AI agents want to identify your crypto wallet using social media

Crypto influencers are taking a preprint, non-peer-reviewed research paper as a terrifying warning about a new unlock for AI agents that allegedly grants them power to deanonymize crypto wallets.

Almost all blockchains like Bitcoin and Ethereum employ pseudonymity in wallet addresses, which are usually presented as a string of characters.

Although wallet addresses are just a string of characters, AIs and easy-to-use agentic tools like Claude Cowork and Perplexity Computer are advancing the capabilities of casual users to deanonymize them.

According to their research, new versions of AI are gaining the power to conduct large-scale deanonymization by taking in posts by billions of humans and linking distinct usernames using highly-processed probability scores.

This is akin to making educated inferences that the person behind one username is likely the same person behind another username.

Researchers used Claude tools by the AI giant Anthropic. The paper is a preprint and as such hasn’t been accepted for publication in a peer-reviewed academic journal. However, its conclusions are potentially disturbing and reinforce concerns about crypto privacy.

Exploiting a common opsec error

Unfortunately, many people re-use the same crypto wallet addresses. Although this is bad practice from an operational security (OpSec) and privacy perspective, the commonplace occurrence allows researchers to glean and infer a tremendous amount of information.

Tracing and deanonymizing crypto has been popular for years at Chainalysis, Elliptic, TRM, Crystal, Coinglass, and Arkham.

However, the use of AI agents to easily link wallets to social and internet platforms is the breakthrough.

Users of Claude Cowork or Perplexity Computer are already asking AI to connect crypto wallets to activity elsewhere.

Four stages of AI deanonymization

Researchers automated hours of manual research by building a pipeline with four stages:

  • In the “extract” step, AI agents searched for identity-relevant data from social posts that indicated interests and writing style. Importantly, the researchers used raw, unstructured text directly from social networks. 
  • The “search” step encoded the extracted data to perform “nearest neighbor” queries across tens of thousands of candidate profiles. 
  • Next, the “reason” phase applied multi-stage, LLM logic using ChatGPT to select the most likely match. 
  • Finally, the “calibrate” stage asked other AI models to double-check, error-correct, and assign confidence scores. This allowed the researchers to present their inferences as to which usernames across social networks were likely the same person.

Although researchers didn’t focus on crypto wallets specifically — they focused on linking Reddit, Hacker News, and LinkedIn profiles — the implications for crypto are obvious.

Most concerningly, their financial cost per deanonymization attempt was, in many cases, less than $4, putting the capability of deanonymization well within reach of even conservatively funded adversaries.

Mert Mumtaz, CEO of Helius Labs, amplified the research within the crypto community.

Blockchain transactions are visible to anyone. Although crypto is already accustomed to the use of machine learning, heuristics, and clustering algorithms to link wallet addresses to real-world identities by correlating on-chain behavior with off-chain data, this new research demonstrates how off-blockchain data sets like forum posts and social media activity are now exponentially larger in size and trivially automatable.

Anthropic Refuses Pentagon Ultimatum, Sets Precedent for Crypto

Anthropic Refuses Pentagon Ultimatum, Sets Precedent for Crypto

Anthropic CEO Dario Amodei publicly rejected the Pentagon’s demand on Thursday. The Defense Department wants unrestricted military use of the company’s AI technology. The deadline, just hours away, could see the $380 billion startup expelled from the US military’s supply chain.

The showdown marks the first time a major AI company has publicly defied a US government threat to seize control of its technology.

The Standoff

In a blog post published on Anthropic’s website, Amodei called the Pentagon’s threats “inherently contradictory,” noting that one designates Anthropic as a security risk while the other treats Claude as essential to national security.

“Regardless, these threats do not change our position: we cannot in good conscience accede to their request,” Amodei wrote.

The dispute centers on two conditions Anthropic placed on military use of Claude. The company bars autonomous targeting of enemy combatants and prohibits mass surveillance of US citizens. The Pentagon views these as unacceptable limitations on lawful military operations.

Anthropic said the Pentagon’s “final offer,” received overnight Wednesday, failed to address its core concerns. “New language framed as compromise was paired with legalese that would allow those safeguards to be disregarded at will,” an Anthropic spokesperson said in a statement, as reported by The Hill.

Defense Department spokesman Sean Parnell issued a public ultimatum on Thursday. He gave Anthropic until 5:01 pm ET on Friday to grant unrestricted access to Claude Gov — or face termination of the partnership and designation as a supply chain risk.

“We will not let ANY company dictate the terms regarding how we make operational decisions,” Parnell wrote on X.

Timeline of Escalation

On Tuesday, Amodei met directly with Defense Secretary Pete Hegseth, during which Pentagon officials outlined three consequences for noncompliance. First, removal from military systems. Second, supply chain risk designation that would bar other defense contractors from using Anthropic products. Third, the invocation of the 1950 Defense Production Act to legally compel the company to hand over its technology.

Amodei argued in the blog post that the refusal is also grounded in technical reality. “Frontier AI systems are simply not reliable enough to power fully autonomous weapons,” he wrote, adding that without proper oversight, such systems “cannot be relied upon to exercise the critical judgment that our highly trained, professional troops exhibit every day.”

Republican Senator Thom Tillis criticized the Pentagon’s handling of the dispute. “Why in the hell are we having this discussion in public? This is not the way you deal with a strategic vendor,” Tillis told reporters.

What’s at Stake

For Anthropic, the immediate exposure is a $200 million military contract. But the supply chain risk designation carries far broader implications. It would force every defense contractor to verify that they don’t use Anthropic products in their operations.

The competitive landscape is shifting fast. Elon Musk’s xAI signed a deal to use Grok in classified systems, according to Axios, accepting the ‘all lawful purposes’ standard for classified work. OpenAI and Google are accelerating negotiations to enter the classified space. Anthropic, once the only AI company cleared for classified material, risks losing that first-mover advantage entirely.

Why Crypto Should Pay Attention

The Pentagon’s willingness to invoke the Defense Production Act against a technology company sets a precedent that extends beyond AI. If the government can legally compel an AI firm to remove safety restrictions on national security grounds, the same framework could, in theory, be applied to compel crypto companies to modify privacy features or weaken transaction safeguards.

The standoff also strengthens the case for decentralized AI development. A centralized AI provider can be pressured — or legally compelled — to strip away guardrails at a government’s demand. That validates the thesis that decentralized alternatives offer more resilient infrastructure against state coercion.

Anthropic’s rapid growth has already raised concerns for crypto markets. The company’s $380 billion valuation and AI-driven disruption of traditional software revenue are putting pressure on private credit flows that correlate closely with Bitcoin.

Anthropic also has a historical link to crypto: FTX’s bankruptcy estate held a significant early stake in the company, which it later sold to help fund creditor repayments.

The Friday deadline will pass, but the real question begins after: whether the Pentagon follows through, and what that means for every technology company drawing a line between government contracts and product integrity.

Decibel Perpetuals Exchange Launches on Aptos

Published

Perpetual Volume & Open Interest chart

The perp DEX is incubated by Aptos Labs and plans to leverage the blockchain’s high speed to deliver a highly responsive trading experience.

Decibel, a perpetual derivatives decentralized exchange (DEX) incubated by Aptos Labs, launched its mainnet today alongside its official points program.

The DEX is starting with perpetual markets, before expanding to spot and real-world assets (RWAs), similar to the progression taken by market leaders Hyperliquid and Lighter.

According to a press release shared with The Defiant, Decibel’s testnet generated “over 1 million user trades per day” across more than 130,000 daily active users (DAU).

So far, the DEX has processed $6.4 million in volume since its mainnet launch and hosts $57 million in total value locked (TVL), according to DeFiLlama.

The DEX is based on a central limit order book (CLOB) model, and hosts its risk engine onchain, ensuring functions such as auto-deleveraging are directly verifiable via the block explorer.

While Aptos Labs incubated Decibel and the DEX is built on the Aptos Layer 1, the DEX also uses X-chain accounts to enable deposits from Ethereum and Solana.

The perpetual market remains red hot, with more than $730 billion traded across all DEXs in February, roughly the same amount traded throughout all of 2023. Activity has cooled off since volumes peaked at $1.37 trillion in October, but the sector remains one of the most popular in DeFi.

Brylee Whatley, the Head of the Decibel Foundation, told The Defiant, “On the acquisition side, Decibel has invested heavily in aligning incentives with real usage. Season 1 of our Amps points program is live and is designed to reward genuine trading activity. But incentives only get users through the door.”

“What keeps traders is trust in the system they are trading on. Everything on Decibel is transparent – the infrastructure, risk approach and liquidation logic. We built an exchange where serious traders feel confident deploying real capital,” they added.

While a majority of DEXs offer tokenized equity and commodity offerings, only HyperUnit’s TradeXYZ, Lighter’s tokenized Korean stocks, and Ostium have found sustained liquidity and success.

Whatley also touched on the future vision for Decibel as it enters the highly competitive tokenized RWA trading space, citing Aptos’ existing success in the world of RWAs and the chain’s global go-to-market reach.

“Imagine using tokenized RWA holdings – treasuries, equities, commodities – as collateral to trade perpetuals, or using your crypto portfolio to margin equity positions. That kind of cross-asset capital efficiency is impossible at a traditional brokerage and isn’t available on other DEXs,” Whatley concluded.

Bitcoin price outlook: analyst warns it’s ‘premature’ to say bear market is over

  • Bitcoin price trades around $67,500.
  • The asset rose to near $70,000 but is facing key resistance.
  • Analyst Rekt Capital warns that it’s “premature” to say the current bear market is over.

Bitcoin price is hovering around $67,500 after retreating from highs near $70,000.

The spike to intraday highs on Wednesday saw chatter across ‘Crypto Twitter’ shift to the potential for BTC to have bottomed out and prospects of a sharp uptick.

While bullish sentiment continues to permeate the crypto market, one analyst is cautioning against “premature” calls of the bear market being over.

This even as US spot Bitcoin ETFs take fresh inflows to cut year-to-date outflows to under $2 billion.

Bitcoin retreats from $70k as analyst warns of further declines

Macroeconomic and geopolitical headwinds have meant Bitcoin has found it hard to break higher since recovering from lows near $60,000 reached in early February.

However, the bellwether crypto asset surged toward $70,000 ahead of Nvidia’s earnings report on Wednesday, February 25, 2026.

Like gains across equities, Bitcoin’s uptick benefited from anticipation around Nvidia’s earnings report.

But despite strong AI-driven results, stock futures stalled, and BTC pulled back, trading to around $67,500 as of writing.

Nvidia shares also fell, down more than 5% at open on Thursday. Reaction to the chip giant’s earnings beat impacted BTC.

Despite this pullback, many traders are upbeat after US spot Bitcoin ETFs snapped a recent losing streak, with over $750 million in net inflows over two days. The flip has the market trending with mixed signals.

However, according to crypto analyst Rekt Capital, it’s premature to say the bear market is over.

“The shortest Bitcoin Bear Market lasted 365 days. Bitcoin is currently ~140 days into its current Bear Market,” he posted on X, adding:

“Any talk of the Bear Market being over already is probably premature.”

Spot ETF inflows, on-chain metrics and macro shifts could be key factors in this cycle. But Rekt believes the technical picture says a lot.

In this case, the analyst points to historical cycle bottoms and BTC’s slide below the 200-week exponential moving average.

Even with recent inflows reversing recent outflows to a degree, institutional demand is low, and that could limit any upside.

BTC price analysis

Technically, Bitcoin’s retreat from $70,000 exposes support at $68,000-$68,500.

With a breakdown to $67,500, bulls risk an acceleration toward $60,000.

Rekt shares this outlook by noting that bulls remain vulnerable as long as price fluctuates below the 200-week EMA.

The moving average has acted as resistance in previous bear markets, including in 2018.

“Ultimately, as long as Bitcoin remains below the 200-week EMA, history suggests price will favour additional downside,” the analyst noted.

Earlier this month, analysts at Standard Chartered cut their target for BTC in 2026 to $100,000 and forecast a potential retest of $50,000 before a fresh rally higher.

Nasdaq Files to List VanEck JitoSOL ETF Tied to Solana Liquid Staking

Nasdaq Files to List VanEck JitoSOL ETF Tied to Solana Liquid Staking

Nasdaq has filed a proposed rule change to list the VanEck JitoSOL ETF, a fund designed to hold the Solana-based liquid staking token JitoSOL.

Liquid staking allows users to stake tokens to help secure a proof-of-stake network while receiving a transferable token in return that represents the staked assets and accrued rewards.

Jito Foundation president Brian Smith told Cointelegraph that if the fund is approved, staking rewards would not be distributed separately but instead reflected in the fund’s net asset value.

Because JitoSOL automatically compounds rewards, each token held by the trust would represent the underlying deposited SOL along with any staking yield accrued on the Solana network.

The exchange submitted the proposal under Nasdaq Rule 5711(d), which governs commodity-based trust shares, seeking approval to list and trade shares of a trust that would hold JitoSOL directly.

Created by the Jito Network, JitoSOL (JTO) is a liquid staking token backed by SOL deposited into a staking pool on the Solana network. It lets holders earn staking rewards through a transferable token without directly running validators or managing onchain staking.
