The U.S. Treasury has ordered the freezing of more than $130 million in cryptocurrency linked to Iran, as tensions between the two countries have escalated. On Tuesday, Treasury Secretary Scott Bessent confirmed the action is part of a broader effort to disrupt Iran’s access to proceeds from illicit activity, including through digital assets.

The development comes shortly after blockchain investigator Specter highlighted on-chain activity indicating that Tether had frozen four Tron wallets containing $131 million worth of USDt (USDT). Bessent said the wallets are tied to the Central Bank of Iran, naming the targeted addresses in an X post.

Key takeaways

• U.S. Treasury ordered the freezing of over $130 million in crypto held in wallets linked to Iran, according to Scott Bessent.
• On-chain investigator Specter connected the freeze to Tether’s action against four Tron wallets holding $131 million of USDT.
• Bessent linked the move to the wider U.S. push to restrict Iranian access to illicit financial flows during renewed hostilities.
• The freeze follows a prior action in April, when Tether reported freezing more than $344 million in USDT at the request of U.S. authorities.

Treasury confirms a new freeze linked to Iran

Bessent confirmed on Tuesday that the U.S. government directed the freezing of cryptocurrency held in wallets “tied to the Central Bank of Iran.” He framed the measure as part of an ongoing U.S. strategy to “disrupt and degrade Iran’s illicit financial activities” and to prevent the Iranian regime from accessing proceeds tied to illicit revenue streams.

He also emphasized that the Treasury will continue to “aggressively follow the money,” signaling that additional asset-targeting actions could follow if more wallets are identified through investigations.

Earlier coverage referenced on-chain signals from Specter, which pointed to the specific USDT freeze activity. Specter’s analysis indicated that four Tron wallets were frozen after holding roughly $131 million in USDT, aligning with the figure Bessent cited regarding the U.S. order.

Why stablecoin freezes matter during renewed tensions

The Treasury action underscores how stablecoins, despite being designed to track fiat value, can still sit at the center of sanctions enforcement. When authorities identify addresses connected to sanctioned institutions or networks, freezes can limit the ability to move funds quickly—even if the assets are technically “tokenized” rather than held directly in traditional bank accounts.

In this case, the freeze is tied to hostilities and intensifying U.S.-Iran tensions. The U.S. said it renewed its blockade of Iranian ports, while Central Command announced a new wave of strikes on Iran. Iran’s military, in turn, claimed it carried out drone strikes against U.S. military facilities at Jordan’s Al Azraq Air Base.

That geopolitical backdrop helps explain the urgency of targeting digital assets. For sanctions planners, stablecoins can function as high-speed rails in attempts to move value across borders—making them a logical focus during periods when financial pressure is meant to disrupt procurement networks and operational funding.

A pattern in April and beyond

This is not the first time Tether-related freezing activity has been linked to U.S. sanctions against Iran. In April, Tether confirmed it had frozen more than $344 million in USDT at the request of U.S. authorities, described as an earlier wave of actions consistent with the same enforcement theme: using token controls to prevent access by designated entities.

Separately, Bessent previously said in May that the U.S. has seized around $1 billion in Iranian crypto assets as part of a broader pressure campaign against Iran known as Operation Economic Fury, which launched in March 2025. In a statement in June, Bessent described the operation as targeting foreign procurement networks that support the Iranian military’s efforts to acquire weapons.

Taken together, Tuesday’s reported freeze fits an established trajectory: U.S. authorities identify wallets, impose restrictions through sanctions processes, and then coordinate with market participants capable of freezing stablecoins tied to those addresses.

What to watch next: identification, enforcement, and transparency

For investors, traders, and builders, the practical question is less about whether USDT will “hold its value” and more about how sanctions compliance and wallet targeting continue to affect where stablecoins can flow. These freezes can quickly reduce the ability of certain wallets to access funds, and they can also influence how analysts and market participants assess wallet-level risks associated with regulated enforcement.

Going forward, readers should watch for whether additional Iranian-linked wallets are identified through on-chain investigations and whether further freezes are publicly confirmed by U.S. officials and stablecoin issuers. The key uncertainty remains how widely the freeze net expands—both in terms of the number of wallets and the total value affected—as U.S.-Iran tensions continue to evolve.

Zcash (ZEC) gained much popularity as it moved toward the $505 region but faced significant selling pressure. The move was met with a retreat as traders decided to take profits in one of the most critical psychological resistance regions on the charts.

The development caused controversy among traders regarding the cryptocurrency’s future. Some suggest that the rejection indicates reduced momentum after the fast-moving advance, while others say the retracement is natural after the gains.

However, despite the negative move, ZEC remains above the support levels and the overall recovery setup remains intact. In any case, the following trading sessions will define which side wins.

Zec Retreats Amid Major Resistance Rejection

After reaching around $505, ZEC moved down toward the $466 level due to an increase in profit taking. The high number of leveraged longs at the resistance level provided additional selling pressure when prices reversed course.

This drop in price triggered numerous liquidations and helped market makers take advantage and push prices down temporarily. Soon after, buyers emerged at the $440 support level to prevent the fall in prices beyond that.

This support level is crucial for the existing market structure, as a sustained breach would give an impetus to the bears to move further downward. On the other hand, a successful defense of this level means buying interest still exists.

Social Sentiment Falls While Confidence Rises

The market’s mood has changed significantly over the past few weeks as well. As per Santiment, there was an uptick in social activity around Zcash after it dipped below $362 amid the revelation of the vulnerability of the Orchard shielded pool. Daily social mentions exceeded 1,100 in those days as traders responded to the risk.

On the other hand, social sentiment fell dramatically as the price recovered by almost 29%. Low social activity does not necessarily indicate a bearish sentiment. In most scenarios, less chatter indicates a relatively calm market and fewer panic sales.

Ironwood Network Upgrade Improves Future Prospects

Among the major reasons to be optimistic about Zcash’s future is the scheduled Ironwood network upgrade.

According to developers, the Ironwood network upgrade will be implemented in several days, bringing enhanced mathematics-based proof of concept designed to protect against unnoticeable forgery in Zcash’s privacy pools.

The scheduled network upgrade comes after its emergency fix for the issue related to the vulnerability of the Orchard shielded pool.

Investors find the network upgrade important for Zcash’s future prospects, regardless of current price dynamics.

Technical Indicators Highlight The Most Critical Resistance Level

Technical analysis indicates that ZEC is set to face another crucial challenge.

The first resistance level lies in the range of $480 to $490. It incorporates past horizontal resistance, the upper Bollinger Band, and the 0.786 Fibonacci retracement level.

According to analyst Ardi, the potential to break past $480 on the daily chart can give bulls hope of reaching $500. A further breakdown below this level may provide an opportunity to target the next resistance level at $540.

CryptDollar, another analyst, has also pointed to this resistance level as the most critical one to watch before confirming the continuation of the latest recovery trend.

Momentum Indicators Still Favor Bulls

While there are no definitive signs yet, several signals support the current trend.

Chaikin Money Flow is still positive at 0.13, indicating capital inflows into the asset. In addition, the Aroon Up indicator remains above 92%, meaning the uptrend is still alive.

TradingView’s Moving Average still shows a Strong Buy signal despite several neutral momentum oscillators.

Liquidation charts can also be helpful for gauging future volatility. Large short positions are formed in the range of $480 to $500. As a result, a breakout of the range will likely bring more momentum to the next leg higher due to short liquidations.

The U.S. commodities regulator has moved to prevent Kalshi, a registered prediction market platform, from reversing Michigan trades—sparking fresh legal friction between federal oversight and a state court order. The dispute centers on whether Kalshi must unwind already executed sports betting contracts for Michigan users while litigation over Michigan’s sports betting laws continues.

On Tuesday, the Commodity Futures Trading Commission (CFTC) ordered Kalshi not to comply with the Michigan order and instead continue operating. The clash follows an earlier ruling on June 29 by Ingham County Circuit Court Judge Rosemarie Aquilina, who directed Kalshi to stop offering sports betting contracts to Michigan users during the ongoing case.

Key takeaways

• The CFTC says canceling already executed prediction market trades would disrupt market certainty and create a cascading effect across derivatives markets.
• Kalshi argues the situation forces it to choose between conflicting obligations: comply with a state court directive or follow federal regulatory requirements.
• The controversy underscores an ongoing jurisdictional tension between the CFTC and multiple state regulators regarding prediction markets.
• CFTC Chair Michael Selig warned that the agency will continue legal action against states that attempt to impose penalties on CFTC-registered exchanges.

Michigan judge’s order vs. federal directive

Michigan’s court case began with a directive that targeted Kalshi’s ability to provide sports betting contracts to residents of the state. According to Cointelegraph reporting, Judge Aquilina ordered Kalshi to cease offering those contracts to Michigan users while the lawsuit proceeds over whether Kalshi’s offerings violate state sports betting laws. Earlier coverage from Cointelegraph described the scope of that order and the legal context surrounding it.

But on Tuesday, the CFTC intervened. In a press statement, the regulator ordered Kalshi not to comply with the Michigan directive and to continue operating despite the state order. The CFTC press release frames the issue as one of maintaining federal authority over registered entities and executed derivatives contracts.

Kalshi says it unwound trades—and now faces contradictions

Kalshi’s response highlights the practical dilemma regulators rarely address directly: companies caught between courts can end up violating one authority while trying to obey another.

In a statement posted on X, Robert DeNault, Kalshi’s head of enforcement and legal counsel, said the company is “disappointed” and described the federal action as placing Kalshi in an “impossible position.” DeNault’s statement on X argues that Kalshi already followed the Michigan court order by unwinding the trades, but the new CFTC directive appears to contradict that requirement.

DeNault’s wording underscores the core problem: Kalshi believes it is being pushed into a compliance conflict, where it may be required to reverse actions taken under state instructions while also meeting federal regulatory expectations.

Reuters reported that Kalshi is reviewing the CFTC’s order and considering its next steps. According to Reuters, the company is weighing how to respond given the opposing directives.

Why the regulator says “canceling” is a market-breaking precedent

The CFTC’s position is grounded in the mechanics of derivatives contracting. The regulator argues that canceling trades already executed is not just a procedural change—it threatens contract certainty across the marketplace.

In the same dispute framing, the CFTC characterized cancelation of executed trades as unprecedented and potentially destabilizing. The regulator’s message is that prediction markets operate through contractual certainty, and that undermining that certainty would ripple outward beyond any single platform.

The CFTC also emphasized that it will not allow states or state courts to pressure registered entities into violating the Commodity Exchange Act and CFTC regulations. That argument is aimed directly at the core tension at the center of the Michigan case: whether states can effectively override federal rules through injunctions and court orders applied to an exchange that is already registered with the CFTC.

Broader conflict: federal authority vs. state-by-state attempts

This is not presented by the CFTC as an isolated disagreement. The regulator has repeatedly argued that prediction markets fall within the federal scope when they are run through CFTC-registered structures.

As the dispute is framed, Michigan is described by the CFTC as the first state to attempt interference with executed derivatives transactions through a court order. That characterization matters because it suggests the CFTC views the issue as moving from “licensing and legality” arguments—traditionally handled at the state level—into the domain of how executed federal derivatives contracts must be honored.

During an appearance on Fox Business, CFTC Chair Michael Selig said it is “critical” that the regulator maintains its authority over prediction markets. Selig also stated that the agency has sued nine states and indicated it would continue to challenge states that attempt to impose criminal or civil fines against CFTC-registered exchanges. According to Selig’s remarks, the CFTC’s stance is that state actions cannot be allowed to erode the federal regulatory framework for these markets.

For investors and market participants, the practical implication is that prediction market compliance may remain a moving target. Even where a state court order appears clear, a federal regulator may step in to enforce a different standard. That dynamic increases uncertainty for platforms operating across state lines and could affect how traders evaluate jurisdictional risk when participating in events-based contracts.

What to watch next is how Kalshi navigates the contradiction between the Michigan directive and the CFTC’s order—and whether additional courts or appeals clarify which obligations control when state and federal requirements diverge for already executed derivatives contracts.

This is Part 4 in the technical article series about Bitcoin covenants by Cointelegraph Research. To read the previous article, click here. 

The following opcodes do not independently implement full covenant functionality. Instead, they are building blocks for constructing covenants when combined with other opcodes or script elements.

OP_CHECKSIGFROMSTACK (OP_CSFS) and OP_CAT

OP_CSFS is a proposed opcode that would allow Bitcoin script to verify signatures over arbitrary messages supplied on the stack. It is different from OP_CHECKSIG, which verifies signatures over the spending transaction according to the active SIGHASH mode. By enabling signature verification for data other than the serialized transaction details, OP_CSFS enables a broader class of constructions, including oracle-based scripts where an external party signs off-chain messages that represent real-world events. For example, a trusted oracle could publish Schnorr signatures over messages that encode external outcomes, and an OP_CSFS-based script could condition payments on the presence of a valid oracle signature. 

On its own, OP_CSFS does not implement covenants. It can authenticate external data, but it does not bind that data to the structure of the spending transaction. That binding requires OP_CAT.

OP_CAT is a proposed opcode that enables the concatenation of two values on the script stack to form a single byte sequence instead of two distinct ones. When combined with OP_CSFS, it allows the script to assemble selected transaction fields into a canonical message and verify that a provided signature commits to that message.

OP_CSFS and OP_CAT taken together can perform introspection by compelling the spender to provide transaction details on the witness stack. If both OP_CSFS and OP_CHECKSIG succeed for the same signature, it proves that the correct transaction details have been passed on to the witness stack and can be further reasoned about. By checking the transaction against a predefined template, a covenant construction, similar to OP_CTV, can be enforced. Two minimal assemblies show how this works:

OP_CAT + Schnorr Tricks

Using OP_CAT, covenant-like constructions can be enforced under Taproot without OP_CSFS by exploiting how Schnorr signatures interact with the Taproot sighash rules defined in BIP 341. The construction repurposes OP_CHECKSIG which is ordinarily used to authenticate ownership of a private key, to a transaction introspection tool.

A schnorr signature is a pair ⟨R, s⟩. Under normal circumstances, this schnorr signature is generated by selecting a secret nonce k, deriving the point R = kG, and computing the signature value s as a function of the message hash and the private key. The verifier then checks the signature pair ⟨R, s⟩ against a public key P and the message being signed. The randomness of k ensures that s is unpredictable and non-reproducible without knowledge of the private key.

The introspection trick works by eliminating randomness by fixing some of these variables in advance. Instead of choosing R randomly during signing, the script commits to a predetermined value of R and to a fixed public key P. Because Schnorr verification follows a deterministic equation, it becomes possible to construct these values so that the signature scalar s must equal a hash of specific transaction parameters.

The spender provides R and s on the witness stack. OP_CAT concatenates them into the signature pair ⟨R, s⟩ in the format OP_CHECKSIG expects. The script verifies this against the hardcoded public key P. Because R and P are fixed to the base point G, OP_CHECKSIG will only accept the pair if s equals the SHA256 hash of the actual transaction data computed by the protocol. The spender cannot fabricate an s that passes OP_CHECKSIG unless it genuinely reflects the real transaction data. The spender must grind the transaction data until its SHA256 hash ends in a specific byte, which takes roughly 256 attempts on average and adds negligible cost. 

In this way, OP_CHECKSIG is no longer used to authenticate ownership of a secret private key but instead to enforce that the transaction matches a specific template.  The expressiveness is broadly comparable to OP_CTV.

Because this approach depends on Schnorr signatures and the taproot sighash algorithm, it applies only to SegWit v1 outputs and does not extend to SegWit v0 outputs which uses the BIP-143 digest and ECDSA signatures.

In our next article we will commence our discussion of OP_CCV, which is even more capable than OP_CSFS and OP_CAT combined.

Bitcoin (BTC) should repeat history and put in a bear-market bottom when a classic indicator hits zero, a trader says.

Key points:

• Bitcoin classic two-month stochastic RSI signals are valid this bear market, Max Crypto said.
• The bear market will be over once the indicator reaches zero again.
• RSI divergences provided advance notice of the BTC price rebound beyond $64,000 this month.

Bitcoin stochastic RSI bottom signal “will happen again”

In an X post at the weekend, Max Crypto went on record to forecast the end of the 2026 bear market when the stochastic relative strength index (RSI) hits a new swing low.

“Stoch” RSI is a derivative of RSI, a popular leading indicator, with a greater bias on recent price moves.

“Every time the 2M Stoch RSI had a bullish cross and dropped to 0, $BTC bottomed,” Max Crypto wrote in accompanying commentary. 

“This happened in 2014, 2018, and 2022, and it will happen again.”

Two-month stoch RSI measures 4.81, having dropped into its sub-30 “oversold” zone during March, data from TradingView confirms. Current levels were last observed just over three years ago.

Stoch RSI has already formed a focus for market participants this year, with daily moves previously drawing comparisons to the 2022 bear market. 

In April, crypto trader Quantum Ascend described BTC price history as “playing out nearly perfectly.”

Bear-market RSI cues keep coming

Turning to traditional RSI data, traders continue to look for bullish cues as BTC/USD treads water above $60,000.

On Sunday, trader and investor BitcoinHyper eyed a bullish divergence against the S&P 500.

At the start of June, daily RSI dropped to just 15, marking one out of just six of what trader Osemka later called “extremely powerful selling events.”

“There’s been one case where extreme $BTC RSI (1D at 15) failed to break the lows and only managed to sweep it. That was at the end of accumulation range in 2015,” he continued on Tuesday. 

“I’m mentioning it now since we have also only swept the low on such powerful move down.”

Osemka implied that a deeper RSI retracement could still emerge, marking a price reversal in-line with previous bear markets.

Bitcoin’s return above $64,000 this month, meanwhile, came after bullish RSI divergences across multiple time frames.

A solo Bitcoin miner hit the jackpot and validated a solo block with a single Bitaxe mining rig, marking a rare win that beat massive statistical odds.

The retail Bitcoin miner secured a 3.125 Bitcoin (BTC) block reward, currently worth about $200,000, on Friday at block number 957382, according to blockchain data from mempool.space. 

The miner was using a single Bitaxe mining rig, according to the BTC mining pool Public Pool. The Bitaxe was a budget, lower-power Bitcoin miner that costs less than $200 and has a hashrate of about 1 terahash per second (TH/s), which is a tiny fraction of the global Bitcoin network.

The solo block reward shows that even a sub-$200 investment in a mining rig can lead to a statistically rare payday for retail miners. 

Another solo Bitcoin miner validated a solo block in April, through CKPool’s solo mining service. Earlier in February, another retail miner validated a solo block using rented hashrate from a mining provider, meaning that he didn’t own the physical mining rig that solved the block.

Solo BTC miners bag $4.7 million during the past year

While mining a solo block is statistically rare, this marks the 12th Bitcoin block validated by a hobby-level miner so far in 2026, pushing the past 12 months’ total payouts to more than $4.7 million for retail miners.

Solo blocks mined increased by 41% year-on-year, as solo miners have validated a total of 24 blocks during the past year, according to solo miner data aggregator Bennet. This brings total rewards paid to solo miners to 75.4 Bitcoin, or $4.7 million, for the past year.

The average interval for solo Bitcoin blocks stands at 15.2 days, while the longest drought without a successful solo block stands at 58 days.

Fears that artificial intelligence would trigger a wave of catastrophic decentralized finance (DeFi) hacks in what was coined as a “hackpocalypse” have not materialized, according to Dragonfly managing partner Haseeb Qureshi.

While the incident count grew to a record high, the median size of hacks has dipped below $500,000 this year, down from over $2 million in 2025. Qureshi argued that this shows malicious actors using AI are targeting “small protocols and abandonware” while larger DeFi protocols have fortified themselves against AI’s threat.

Excluding outlier months with large incidents, such as the Bybit hack in February 2025 along with the Drift Protocol and KelpDAO exploits in April of this year, 2026 has still seen less value hacked per month than the previous year, said Qureshi.

The comments come in response to concerns shared by blockchain security platform OpenZeppelin’s founder, Manuel Aráoz, who said that he considers “all of DeFi unsafe,” citing the growing ability of AI coding agents to identify smart contract vulnerabilities. 

Broader industry datasets, which include centralized platforms, wallet compromises and phishing, as well as DeFi exploits, offer a less reassuring picture. In April, crypto hacks surged, resulting in losses of around $644 million, marking an over one-year high last seen in February 2025 when the $1.4 billion Bybit hack pushed monthly losses to $1.46 billion, according to DefiLlama.

Crypto hacks fall 47% in H1, but crypto industry not necessarily safer: CertiK

Losses to cryptocurrency hacks fell 46.8% year-on-year to $1.32 billion in the first half of 2026, but blockchain security company CertiK argued that the Web3 industry’s lower headline losses do not necessarily mean the industry is safer.

While it marks a significant drop in dollar value, last year’s figures were skewed by the $1.4 billion Bybit hack, the largest in crypto history, CertiK told Cointelegraph.

During the second quarter of 2026, over 70% of the losses stemmed from the KelpDAO and Drift Protocol exploits, which were largely attributed to North Korean state-sponsored hackers.
