Binance has tightened its compliance controls following the European Union’s latest sanctions package against Russia, blocking transactions involving HTX and a group of other crypto-asset service providers targeted by Brussels.

The restrictions underline a growing reality for the cryptocurrency industry: while decentralized networks such as Bitcoin remain permissionless, access to the deepest pools of centralized liquidity is increasingly governed by sanctions, anti-money-laundering rules and other regulatory requirements.

Binance announced on August 14 that it would stop processing transactions involving 11 additional crypto platforms from August 23, including HTX, Rapira, Aifory Pro, ABCeX, WhiteBird, NoOnecrypto, Tradex, Monease, BitPapa, Exnode and EXMO. The exchange said the decision was driven by recent regulatory developments and warned that transactions involving the affected services could be held for compliance review. Wallets connected to those platforms could also face restrictions.

The move followed the European Union’s 21st package of sanctions against Russia, adopted on July 23. The package introduced transaction bans against 14 crypto-related service platforms based outside the EU and included companies operating in jurisdictions such as Georgia, Panama, the United Arab Emirates, the Marshall Islands, Kyrgyzstan and Belarus. The EU said the targeted platforms were providing a financial lifeline that could help Russia circumvent existing sanctions.

Importantly, the restrictions are not limited to Russian-based exchanges. HTX, formerly Huobi, was among the platforms targeted despite being an international crypto exchange. The EU’s listing specifically identifies HTX under the legal entity Huobi Global SA, with the transaction ban taking effect on August 23.

The EU has simultaneously expanded its ability to pursue crypto businesses operating outside the bloc. For the first time, Brussels introduced a mechanism that could eventually allow a broader transaction prohibition against crypto-asset service providers in third countries that authorities determine are being used by Russia to evade sanctions. This represents a significant expansion of the EU’s approach from targeting specific entities toward potentially restricting entire service relationships.

The pressure on HTX is not entirely new. In May, the United Kingdom designated Huobi Global SA under its Russia sanctions regime, alleging that it had provided financial services connected to entities associated with Russian sanctions evasion. HTX disputed the implications of that designation, arguing that the named legal entity was separate from the exchange. UK authorities subsequently took the position that HTX falls within the sanctions framework because of its ownership relationship with Huobi Global.

Binance’s latest decision illustrates how these sanctions increasingly propagate through the broader crypto ecosystem. A platform does not necessarily need to be directly sanctioned in every jurisdiction to become difficult to access. Once a major centralized exchange decides that transactions involving a particular service create unacceptable compliance risk, users may find that moving funds between the two platforms becomes significantly harder.

That creates a sharp contrast between the underlying blockchain infrastructure and the companies operating around it.

Bitcoin itself has no central authority capable of stopping a valid on-chain transaction. Ethereum and other public blockchains operate on the same basic principle. But most users still depend on centralized exchanges for fiat conversion, liquidity, custody, derivatives and access to professional trading markets. Those intermediaries operate within legal jurisdictions and therefore have obligations that the blockchain protocol itself does not.

The distinction is becoming increasingly important as governments target crypto networks as part of broader sanctions enforcement. The objective is not necessarily to make blockchains technically incapable of moving funds. Instead, authorities can make sanctioned entities increasingly isolated from regulated financial infrastructure and major liquidity venues.

Recent events surrounding HTX illustrate how that isolation can develop. Blockchain analytics firms have also scrutinized wallet activity associated with the exchange following the UK sanctions, while reports this week said some Kraken customer accounts were temporarily locked after wallets linked to HTX sent thousands of small transfers to Kraken-related addresses. The incident highlights how sanctions screening can affect transactions even when users themselves are not sanctioned.

For the crypto industry, the implications are broader than Binance and HTX. Centralized exchanges are becoming an increasingly important part of the global compliance architecture, effectively serving as gateways between permissionless blockchains and the regulated financial system.

That does not eliminate Bitcoin’s permissionless nature. Instead, it creates a two-layer market: the blockchain remains open, while access to major centralized venues is increasingly conditioned on compliance.

As sanctions enforcement becomes more sophisticated, that distinction may become one of the defining characteristics of the next stage of crypto adoption. Decentralization can preserve the ability to transact on-chain, but liquidity, custody and fiat access remain services that governments can regulate — and centralized exchanges such as Binance are increasingly operating at the intersection of both worlds.
