Elon Musk’s X has made it easier for its U.S.-based users to turn crypto and stock market chatter on their timeline into trades without leaving the app for long.

This feature, now live, allows U.S. users to tap a cashtag like $BTC or $TSLA, see their live charts and related posts and hit the “Trade button. Tapping “Trade” then takes users to one of X’s partner platforms – Interactive Brokers, Moomoo, Gemini,

Kraken or Coinbase – where they can log in or sign up and complete the order.
X is just letting users act quickly on financial chatter on their timeline, without acting as a broker. The actual buying and selling still happens at one of the partner exchanges.

Cashtags have been available on X for years as a way to follow financial market chatter. Earlier this year, the company upgraded them with real-time prices and charts.

Adding a direct path to trade is the next step in Elon Musk’s effort to turn X into a broader finance destination.

“Cashtags close the gap between a ticker on the timeline and the market itself,” Mridul Singhai, X’s product engineering lead, said.

Trueo has announced plans to move its prediction market protocol from Base to Ethereum mainnet and asked users to avoid new Base markets expiring after January 31, 2027.

Trueo said in its migration announcement that the Base application will remain available while the Ethereum deployment is prepared. Trading, market resolution and redemptions will continue, while existing markets will remain accessible through their expiries. The project said TYD used as collateral will keep earning yield during the transition.

Launched on Base in March 2025, the protocol runs binary YES-or-NO prediction markets onchain. Trueo’s documentation describes trading as non-custodial, with transactions executed directly onchain through a custom Uniswap v4 hook. TYD serves as the payment asset for current market positions and oracle bonds under the present deployment.

Trueo keeps Base markets running during Ethereum move

For existing users, the migration will not immediately shut down the Base version. Trueo said markets expiring during 2026 can still be created there, while existing markets will continue operating under their current settlement system. New market ideas requiring an expiry after January 31, 2027 should wait for the Ethereum instance, according to the project.

TRUE, the protocol’s governance and oracle token, will move to Ethereum through an open-ended migration. Trueo has not announced a deadline for token holders to complete the process. The project said future staking and liquidity incentives will operate on Ethereum once the new deployment becomes available.

Current public data shows that the move has not been completed. Trueo’s official deployment documentation still lists its TruthMarketManager, OracleCouncil, OracleBonds, OrderManager and market master contracts on Base mainnet. No Ethereum mainnet deployment addresses appear on that page.

DefiLlama’s Sept. 22 snapshot attributes all $796,126.31 of tracked Trueo TVL to Base. The same data records $9,727.92 in DEX volume during the previous 30 days and identifies Base as holding 100% of tracked protocol TVL.

Ethereum liquidity and integrations drove Trueo’s decision

Explaining its decision, Trueo cited Ethereum’s network effects, available liquidity, integration options and long-term infrastructure. The team said lower execution costs on Ethereum have made mainnet more practical for its product, while the network’s roadmap offers what Trueo described as a neutral and predictable base for development.

Trueo framed Base as useful during the protocol’s earlier experimental period instead of criticizing the Coinbase-linked Layer 2. The team said Ethereum better fits its intended model of a widely integrated, permissionless and highly immutable prediction market, while liquidity growth and reduced trust assumptions remain priorities for the next deployment.

Ethereum’s existing DeFi environment formed another part of the project’s stated reasoning. Trueo said direct access to Ethereum applications and liquidity could provide more integration paths. The team described the Ethereum L1 prediction-market field as less crowded than several competing blockchain environments, presenting that assessment as part of its own migration case.

Vitalik Buterin praises Trueo’s prediction market model

Ethereum co-founder Vitalik Buterin responded publicly on Sept. 21, welcoming what he described as a new prediction-market contender on Ethereum L1. Buterin praised Trueo’s stated focus on decentralization and ethical design, calling it “not corposlop” and saying prediction markets could be used for “interesting and meaningful things.”

His response follows months of public criticism of some prediction-market products. As crypto.news reported in February, Buterin warned that the sector was becoming heavily focused on short-duration cryptocurrency price wagers and sports betting. He described the direction as an “unhealthy product market fit” and discussed hedging and real-world risk management as other possible uses.

In related crypto.news coverage, Buterin proposed prediction-market-style mechanisms as one layer of future onchain governance, paired with a separate preference-setting system intended to resist capture. His latest Trueo comments did not announce an Ethereum Foundation partnership, grant, investment or other formal arrangement with the project.

Trueo plans a new oracle system on Ethereum

Trueo said work surrounding the Ethereum deployment will include a next-generation oracle system for disputed prediction-market outcomes. The migration announcement did not give a launch date or publish Ethereum contract addresses, leaving the Base contracts as the only deployment currently listed in Trueo’s public documentation.

The current protocol uses an optimistic resolution process. Trueo’s resolution documentation says any participant can propose an outcome once a market meets its resolution criteria, beginning a 12-hour challenge period. If nobody raises a valid dispute, the proposed result becomes final at the end of the window.

When a participant challenges an outcome, Trueo’s existing dispute path can move through several levels. The Oracle Council handles an early arbitration stage, followed by escalation to TRUE holders when a further challenge meets the required conditions. At the final level, the protocol randomly selects 11 attesters to determine the market outcome and applicable slashing conditions.

Market definitions are committed onchain when users create them. Trueo records the market question, approved resolution sources and supporting resolution information as immutable strings, according to its documentation. The project says the setup prevents the written market terms from being changed after deployment.

Its published integrity standards prohibit markets that directly create incentives for targeted violence, terrorism, self-harm or other dangerous conduct. Markets lacking clear, publicly verifiable resolution criteria must be canceled under the protocol’s stated rules.

Trueo has not published a deadline for launching its Ethereum deployment or completing the TRUE token migration. During the transition, the project says Base trading, resolution and redemptions will continue, while future staking and liquidity reward programs are scheduled to operate on Ethereum after the mainnet instance goes live.

Kakao Pay and KakaoBank have signed a memorandum of understanding with Fireblocks to explore stablecoin infrastructure and other digital asset services in South Korea.

Fireblocks said in its Sept. 21 announcement that the three companies will test digital asset distribution frameworks through proof-of-concept programs designed around South Korean regulatory, security and service requirements. The agreement does not announce a stablecoin, investment amount, commercial product or deployment date.

The companies plan to examine infrastructure demand and possible digital asset businesses before deciding whether any framework should advance beyond testing. Fireblocks described secure onchain infrastructure as the central technical area covered by the agreement, with stablecoins receiving specific attention.

Kakao Pay and KakaoBank will test stablecoin infrastructure

Kakao Pay brings payments experience to the project, while KakaoBank provides the banking component of Kakao Group’s work on digital assets. Fireblocks identified both executives leading the companies, Shin Won-keun and Yun Ho-young, as co-heads of Kakao Group’s Stablecoin Task Force.

Under the MoU, no single technical design has been selected publicly. The Fireblocks release says the parties will assess distribution frameworks that fit Korea’s domestic rules and security standards before testing their practical use through PoCs.

KakaoBank CEO Yun said the parties expect to combine their technology and expertise to “develop secure and accessible digital asset services.” His statement describes an intended direction and does not confirm a product launch. Kakao Pay CEO Shin said Korea’s developing digital asset market “depends on the reliable flow of digital asset distribution.”

Neither Kakao company disclosed whether a future stablecoin would be issued directly by a bank, another Kakao entity or an outside issuer. The announcement does not specify a blockchain, token standard, reserve structure, custody model or consumer rollout plan.

Fireblocks brings institutional infrastructure to the PoC

Fireblocks says its platform has been deployed by more than 2,500 institutions, including over 100 banks. Company material says its technology supports custody, settlement, stablecoin payments, tokenization, trading and compliance operations across more than 200 blockchains.

Separate data published on Fireblocks’ website says its network processes more than $200 billion in monthly stablecoin volume through more than 300 payment service providers, fintech companies and banks. The figures are Fireblocks’ own platform statistics and have not been presented as Kakao transaction volumes.

Fireblocks CEO Michael Shaulov said infrastructure for Korean banks and payment platforms needs to be “engineered to meet institutional requirements from day one.” His statement accompanied the MoU and concerned the type of system Fireblocks expects the partners to study.

The agreement does not state whether Kakao Pay or KakaoBank has committed to use Fireblocks in a production environment. PoC testing will come before any announced commercial deployment, according to the companies’ stated sequence.

Kakao’s Circle agreement came before the Fireblocks deal

The Fireblocks pact follows Kakao Group’s July agreement with Circle, which covered stablecoin payments, blockchain settlement and digital asset infrastructure. As crypto.news reported in July, Kakao, Kakao Pay and KakaoBank planned to study KRW-based digital assets, cross-border payments and tokenized financial services alongside Circle.

Under the Circle arrangement, Kakao said it would combine its consumer platform network, Kakao Pay’s payment services, KakaoBank’s banking operations and Circle’s blockchain technology. The parties discussed payment and settlement infrastructure, remittances and connections between blockchain networks and existing financial systems.

No won-denominated stablecoin was launched under the July MoU. Crypto.news reported at the time that Kakao and Circle had not set a launch date or confirmed a particular issuance model, while Circle CEO Jeremy Allaire had previously said Circle did not plan to issue its own KRW stablecoin.

The Fireblocks agreement introduces another infrastructure provider into Kakao Group’s stablecoin research without replacing or ending the Circle arrangement. Fireblocks’ announcement does not describe Circle’s role in the new PoCs or state whether the two relationships will share technology.

South Korea is still developing stablecoin rules

Kakao is not the only Korean financial group testing stablecoin systems before final rules take shape. In related crypto.news coverage, KB Financial Group completed a proof of concept in May covering won-denominated stablecoin issuance, offline QR payments, merchant settlement and a Vietnam remittance test.

Toss followed with another trial in July. As crypto.news reported, the financial app operator partnered with Optimism and Sunnyside Labs for a three-month technology program examining payment settlement, compliance and privacy requirements for won-linked stablecoins.

Work on the legal framework remains unfinished. South Korea’s Financial Services Commission has said its planned framework law for digital assets will include stablecoins, while regulators continue preparing rules covering blockchain-based financial infrastructure.

The FSC said in August that discussions over the government’s second-stage digital asset legislation were still underway and cautioned that some reported provisions had not been finalized. The regulator specifically rejected claims that a proposed ownership cap for major crypto-exchange shareholders had already been settled.

A Bank of Korea payment systems report published Sept. 17 said the central bank had created a Digital Asset Research Section after South Korea’s Virtual Asset User Protection Act took effect. The BOK said the unit has participated in legislative discussions concerning KRW-denominated stablecoins while the country develops its digital asset framework.

Prediction market platform Trueo says it will migrate from Base to Ethereum, positioning the move around broader integrations and the next phase of its oracle infrastructure—an onchain component that helps determine outcomes for markets that settle on real-world data.

Trueo launched on Base in March 2025. After the migration, the team says its near-term focus will be pulling in more liquidity while also developing the next generation of its oracle system, which is central to how prediction markets get resolved.

Key takeaways

• Trueo plans to move its prediction markets from Base to Ethereum to pursue wider integration options.
• The project links the migration to building a more advanced oracle system used to verify real-world outcomes.
• Trueo argues Ethereum is better suited for a “fully permissionless” and highly credible oracle approach than staying within Base’s tighter ecosystem.
• The platform is already a top onchain prediction venue, with DefiLlama listing it among the largest by total value locked.

Why Trueo is leaving Base for Ethereum

Trueo’s core rationale is product reach. In its public messaging, the project said it expects Ethereum to provide “higher integration potential” and more upside for its roadmap, while Base would constrain partnerships and integrations mostly to the immediate Base ecosystem.

The team’s framing is less about trading or execution and more about credibility and neutrality at the oracle layer. Trueo’s co-founder, who goes by “Lumberg,” said Ethereum offers the “best” environment for an oracle designed to be credibly neutral and truthful for prediction markets.

That argument also reflects timing and development tradeoffs from Trueo’s initial deployment. Trueo noted that when it launched, Ethereum mainnet gas costs were still relatively high, and some product features were still experimental—factors that made starting on an L2 like Base pragmatic.

Oracle upgrades are central to the migration

For prediction markets, oracles are not a background detail—they are the mechanism that translates real-world events into blockchain-resolved outcomes. Trueo said that attracting liquidity will be a priority after the move, but the larger effort is the rollout of the next generation of its oracle system.

By highlighting oracle development alongside the chain migration, Trueo is effectively treating the migration as a foundation for scaling the reliability and adoption of its market-resolving process. In the team’s view, the “final form” of Trueo is meant to become a platform that is widely adopted and broadly integrated, with a high standard of credibility tied to how its markets are resolved.

From early-stage L2 to a broader, integrated platform

Trueo’s explanation underscores a common lifecycle pattern for crypto startups: begin on a scaling-friendly network while experimenting, then move toward broader connectivity as the product matures. In Trueo’s case, the company specifically contrasted the properties it could aim for on Ethereum—such as being more widely integrated and permissionless—with the limitations it believes exist when remaining within a single L2 ecosystem.

In comments posted publicly, Trueo also described Ethereum as the “best fit” for combining permissionless operation, strong immutability characteristics, and credible oracle behavior—qualities it says align with its ambition to be a widely adopted prediction market platform rather than a niche app confined to a single rollup.

Where Trueo stands in onchain prediction markets

Trueo is already recognized among the larger onchain prediction venues. DefiLlama ranks the platform as the 14th-largest onchain prediction market by total value locked, with TVL reported at $795,687 at the time of publication.

That matters because migration decisions in the prediction market sector can directly affect liquidity and user participation. Even when the underlying smart contracts and oracle logic evolve, chain selection influences where users already operate, where liquidity pools exist, and how quickly new partnerships can integrate.

Trueo’s plan to prioritize liquidity following the move suggests the team is aware of those transition risks—particularly in a category where market depth and participation can be sensitive to where markets are hosted.

As Trueo executes its Ethereum migration, readers should watch for two things: how quickly liquidity can be reassembled on the new chain, and what changes land in its next-generation oracle system—since the oracle design is likely to determine how credible and widely usable its prediction market resolution process becomes.

U.S. federal prosecutors have been investigating whether Binance knowingly allowed trading that violated Iran sanctions, nearly three years after its $4.3 billion federal settlement, according to a Sept. 22 Bloomberg report.

Bloomberg said the Manhattan U.S. Attorney’s Office is leading the inquiry, while the Justice Department’s Criminal Division in Washington is participating. Prosecutors are examining Binance’s compliance controls and whether the exchange knew about the transactions under review, according to the report. Reuters said it had not independently verified Bloomberg’s account.

Binance responded that it maintains a zero-tolerance policy for sanctions violations. The exchange said, “We fully cooperate with law enforcement, and we remain committed to rooting out and shutting down bad actors.” The Justice Department declined to comment to Reuters, while the Manhattan U.S. Attorney’s Office was not immediately available for comment outside normal business hours.

Binance Iran sanctions probe focuses on compliance controls

The reported investigation centers on whether Binance knowingly permitted trading that should have been stopped under U.S. sanctions, according to Bloomberg’s account cited by Reuters. The report did not identify the transactions under review or disclose when prosecutors began examining them.

Scrutiny of the exchange’s Iran-related controls had surfaced months earlier. In March, crypto.news reported that Senators Elizabeth Warren, Chris Van Hollen and Ruben Gallego planned congressional oversight of a reported Justice Department investigation involving Iran-linked transactions. At the time, the inquiry was described as examining whether networks connected to Iran used Binance to evade U.S. sanctions.

Binance disputed claims made in several February reports. In a March 6 response to a Senate inquiry, the company described parts of the reporting as “demonstrably false, unsupported by credible evidence, and defamatory in several material respects.” Binance said its know-your-customer rules prohibit users residing or located in Iran from accessing Binance.com.

$61 million forfeiture complaint names Binance-linked accounts

A separate court action filed on Sept. 14 provides fresh public records concerning Iran-linked funds that moved through accounts on Binance. The Southern District of New York filed a verified civil forfeiture complaint seeking all USDT held in 10 cryptocurrency addresses, court records show. The case is United States v. All USD Tether Held in the Following Cryptocurrency Addresses, No. 1:26-cv-08010.

Prosecutors valued the targeted cryptocurrency at approximately $61 million and alleged it represented proceeds from black-market Iranian crude oil and petroleum sales. The complaint says the money was intended to finance Iranian government and military bodies, including the Islamic Revolutionary Guard Corps.

The filing alleges two Chinese companies, Blessed Trust and Hexa Whale, used Binance trading accounts while handling proceeds connected with Iranian oil sales. Prosecutors said a network of cryptocurrency actors laundered more than $1.5 billion in illicit oil proceeds, while Blessed Trust and Hexa Whale used the U.S. financial system to send or receive tens of millions of dollars.

The forfeiture complaint does not accuse Binance itself of wrongdoing in that proceeding. The Justice Department states that a civil forfeiture complaint contains allegations that remain unproven until a court enters judgment for the government. As crypto.news reported in related coverage, the case is directed at the cryptocurrency held in the identified wallets, not a criminal charge against Binance.

Court records describe the assets as USDT held on addresses operating on the TRON network. The complaint says Tether would burn the tokens covered by a seizure warrant and issue replacement tokens of equal value for transfer into U.S. government custody.

Binance says the firms were offboarded after reviews

Binance has given its own timeline for Hexa Whale and Blessed Trust. In its March congressional response, the exchange said law enforcement contacted it in April 2025 about transactions between Binance wallets and outside addresses with possible terrorism-financing connections. Binance said it supplied KYC and transaction records connected with Hexa Whale in June 2025 and continued reviewing the account afterward.

The company said it removed Hexa Whale from Binance.com on Aug. 13, 2025. A separate set of law-enforcement requests concerning transactions involving other outside wallets arrived during summer 2025, according to Binance. The exchange said investigators then performed a source-of-funds review and offboarded Blessed Trust in January 2026.

Binance maintains that, to its knowledge, no Binance account transacted directly with an Iran-based entity. In another March statement, the company said its investigation found approximately $126.1 million eventually reached wallets linked to Iran after multiple blockchain hops, with as much as $24.1 million reaching IRGC-related wallets. The figures are Binance’s account of its internal review and have not been presented by the company as findings of a court.

The exchange said claims that it fired compliance employees for escalating concerns were false. Binance acknowledged that one employee was dismissed after an internal investigation over what the company described as an unauthorized disclosure of user information, while other compliance workers left voluntarily.

Binance has pointed to staffing and monitoring data while defending its controls. The company says more than 1,500 people work in compliance-related functions, representing roughly 25% of its global workforce. It reported processing more than 71,000 law-enforcement requests during 2025 and claimed exposure to four major Iranian crypto exchanges fell 97.3%, from $4.19 million to $110,000 over two years.

2023 guilty plea imposed monitors and compliance reforms

The current scrutiny follows Binance’s November 2023 criminal resolution with U.S. authorities. The exchange pleaded guilty to offenses involving the Bank Secrecy Act, operating an unregistered money-transmitting business and violating the International Emergency Economic Powers Act. Binance agreed to a total criminal financial penalty of $4.316 billion.

In that case, the Justice Department said Binance knowingly failed to install controls that would stop U.S. customers from trading with users in sanctioned jurisdictions. Federal prosecutors said Binance caused more than $898 million in trades between U.S. users and users ordinarily resident in Iran from January 2018 through May 2022.

The settlement required Binance to retain an independent compliance monitor for three years and improve its anti-money-laundering and sanctions systems. Separate coordinated resolutions involved FinCEN, the Treasury Department’s Office of Foreign Assets Control and the Commodity Futures Trading Commission.

Later scrutiny centered on whether the post-settlement controls were functioning as required. As crypto.news previously reported, Treasury-related oversight gave authorities access to Binance books, records and systems under separate monitoring obligations, while Iran-linked transaction reports prompted renewed questions about compliance.

Meanwhile, the Sept. 14 forfeiture matter is proceeding separately in the Southern District of New York. Prosecutors are seeking a judgment allowing the United States to retain the USDT named in the complaint, while the filing itself states that its allegations remain unproven unless the court awards judgment to the government.

XRP added 7% to nearly $1.52 and SOL 5% to just under $117. Ether rose 3% to nearly $2,740, while BNB and TRX each picked up between 1% and 2%. ZEC was the only large token to fall, down 4% to just above $1,450.

Liquidations in the past hour came to under $11 million, down from more than $300 million an hour at the peak of Monday’s move, which leaves the next leg dependent on buyers rather than sellers being forced out.

AI trade roars back

Equities set a firm tone through the Asian session, meanwhile.

MSCI’s Asia Pacific gauge rose nearly 1% for a fifth straight day of gains, led by chipmakers Samsung Electronics and SK Hynix, which tracked Monday’s rally in U.S. semiconductor stocks. South Korea’s Kospi advanced 2% and Taiwan’s benchmark hit an intraday record.

Artificial intelligence is doing the pulling. The Wall Street rally followed early signs of success for Meta Platforms’ new AI agent, and AMD is on course to pass $1 trillion in market value.

Meta Platforms released Muse, an AI agent that works across Facebook, Instagram and WhatsApp, nearly two weeks ago and it has since passed ChatGPT to become the top free app on Apple’s U.S. App Store. The app has drawn nearly 3 million installs worldwide and almost 40% more iOS downloads in the U.S. and Canada than ChatGPT managed in its own first 12 days on mobile, data from app-tracker Apptopia shows.

Cardano has been added to the official x402 software kit, giving developers the code needed to let an app or AI agent pay for an online service using ADA or tokens issued on the network.

x402 turns the web’s largely unused “402 Payment Required” response into a checkout built directly into an internet request. A service sends back its price and payment instructions, the agent signs a payment and receives the requested data or computing power after the transaction is verified.

That means an agent preparing a report could buy a single dataset when it needs it, without a person opening an account, entering card details or paying for a monthly subscription.

Coinbase created x402 in 2025 before contributing it to a Linux Foundation-backed organization whose members include Visa, Mastercard, Stripe, Google and Amazon Web Services. Solana, the XRP Ledger and several Ethereum-compatible networks already support the standard.

Cardano Foundation engineers began with a specification accepted in June, then built the client and server software needed to request payments alongside a so-called facilitator that verifies and submits them. The initial release supports TypeScript, with Python planned next.

Kakao Pay and KakaoBank, two major players in South Korea’s Kakao ecosystem, have signed a memorandum of understanding (MoU) with digital asset infrastructure provider Fireblocks to explore new opportunities in crypto infrastructure—specifically including stablecoins. The parties said they will run proof-of-concept tests aimed at building digital asset capabilities that fit South Korea’s regulatory, security, and service expectations.

The announcement, made on Monday, did not disclose any launch plans, investment commitments, or implementation timelines. Instead, it frames the effort as an engineering and compliance-oriented exercise to identify how onchain infrastructure can be deployed responsibly in a market that is still taking shape under an evolving regulatory framework.

Key takeaways

• Kakao Pay and KakaoBank are partnering with Fireblocks to test digital asset infrastructure use cases, including stablecoin-related work.
• The MoU centers on proof-of-concept testing tailored to South Korea’s regulatory and security requirements, without any announced rollout timeline.
• Fireblocks says it supports more than 2,500 institutions, including over 100 banks, positioning the partnership as focused on enterprise-grade custody and infrastructure.
• The move adds to a growing cluster of South Korean finance and fintech firms exploring won-denominated stablecoin pathways as regulation develops.

Why Kakao’s infrastructure search matters

Unlike pilots that focus purely on payment trials, this MoU is primarily about the infrastructure layer—how institutions can securely connect to digital assets and operate systems that meet banking-grade standards. Kakao Pay and KakaoBank sit in the heart of South Korea’s digital payments and banking ecosystem: Kakao Pay provides mobile payments and financial services, while KakaoBank is one of the country’s largest internet-only banks.

For firms like these, the practical challenge is not simply adopting blockchain technology, but integrating it in ways that satisfy security controls, operational reliability, and compliance expectations. By working with Fireblocks on proof-of-concept tests, the companies are signaling that they want to validate onchain systems that can withstand enterprise requirements—an issue that often determines whether stablecoin concepts can move from experimentation to production.

What Fireblocks brings to the table

Fireblocks provides digital asset infrastructure used by institutions, and the company says it supports more than 2,500 institutions, including over 100 banks. In enterprise crypto deployments, that kind of track record is often tied to capabilities such as secure custody and infrastructure tooling used to manage digital assets at scale.

While Monday’s MoU announcement does not describe specific technical components, it does clarify the target outcome: secure onchain infrastructure that aligns with South Korea’s regulatory and security landscape. For investors and builders watching South Korea’s stablecoin trajectory, this is a meaningful signal that large local financial institutions are seeking infrastructure partners capable of meeting banking-level standards.

A wave of stablecoin exploration in South Korea

The Kakao-Fireblocks agreement arrives amid a broader pattern of experimentation across South Korea’s financial sector as the country continues building out its digital asset regulatory framework.

Earlier activity includes a separate MoU between Kakao Group and stablecoin issuer Circle, announced in July. According to Cointelegraph’s earlier coverage, that MoU was intended to explore blockchain-based payment infrastructure and digital asset technology, including opportunities around won-denominated stablecoins and related services (see Kakao Circle won stablecoin payment infrastructure).

The stablecoin push is not limited to Kakao. In May, Cointelegraph reported that KB Financial Group completed a won-denominated stablecoin pilot spanning issuance, offline merchant payments, and cross-border remittances (see KB Financial stablecoin pilot offline payments). And in July, fintech company Toss partnered with Optimism and Sunnyside Labs on a proof of concept for won-based stablecoin payment infrastructure (see Toss partners Optimism won stablecoins).

Taken together, these efforts suggest the market is moving beyond pure “whether” questions and increasingly focusing on “how”—including what infrastructure is needed to support stablecoin payments and settlement, including in scenarios that require offline functionality or integration with cross-border flows.

What to watch next for investors and operators

For now, the MoU provides a direction of travel rather than a product roadmap. The lack of a launch or implementation timeline means stakeholders should treat the announcement as an early-stage initiative: proof-of-concept testing will determine what technical and compliance hurdles need to be cleared before any wider deployment.

As South Korea refines its approach to digital assets, the next milestones to monitor are not only regulatory developments, but also whether these infrastructure-focused pilots can evolve into operational systems—especially for won-denominated stablecoin use cases, where payment reliability and security controls are central.

Readers should watch for details on the proof-of-concept scope, results, and whether Kakao’s infrastructure testing leads to further partnerships or public pilots aligned with the country’s expanding stablecoin and payment framework.

South Korean financial companies Kakao Pay and KakaoBank have signed a memorandum of understanding (MoU) with crypto infrastructure provider Fireblocks to explore digital asset opportunities, including stablecoins. 

Under the agreement, the companies will conduct proof-of-concept tests for digital asset infrastructure suited to South Korea’s regulatory, security and service requirements. The initiative aims to help establish secure onchain infrastructure for the country’s emerging digital asset market. 

The announcement on Monday did not include a launch, investment or implementation timeline. 

Kakao Pay operates mobile payments and financial services, while KakaoBank is one of South Korea’s largest internet-only banks. Both are part of the broader Kakao ecosystem. Meanwhile, Fireblocks provides digital asset infrastructure to more than 2,500 institutions, including over 100 banks, according to the company. 

The agreement follows a separate memorandum signed by Kakao Group and stablecoin issuer Circle. In July, the two companies signed an MoU to explore blockchain-based payment infrastructure and digital asset technology. The collaboration included examining opportunities around won-denominated stablecoins and related services. 

Kakao Pay and KakaoBank are among several South Korean financial and technology companies exploring stablecoin opportunities as the country develops its regulatory framework for digital assets.

In May, KB Financial Group completed a won-denominated stablecoin pilot covering issuance, offline merchant payments and cross-border remittances. In July, fintech company Toss partnered with Optimism and Sunnyside Labs on a proof of concept for won-based stablecoin payment infrastructure.
