Crypto API and node infrastructure providers Infura and Alchemy are the latest centralized entities in the cryptocurrency space to blacklist the US Treasury-sanctioned crypto mixer Tornado Cash.

Both platforms are currently blocking remote procedure call (RPC) requests to Tornado Cash, according to Twitter user 0xdev0.

Infura has been known to block access to crypto services in accordance with US sanctions. Users in places like Iran and Venezuela have routinely complained of being unable to use MetaMask. The MetaMask wallet uses Infura as its default RPC endpoint for connecting to the Ethereum network.
