Aave Re-opens Access after Blocking Addresses over Tornado Cash Crackdown

Leading decentralized finance protocol, Aave, revealed that the TRM API on its app was liable for blocking addresses that received Ethereum (ETH) from unknown sources through outlawed crypto mixer, Tornado Cash.

This comes hot on the heels after Aave blocked wallet addresses that received funds from Tornado Cash. Addresses of prominent users including Tron’s founder Justin Sun, Sassal0x, and Shixing Mao, co-founder of Cobo crypto custodian were blocked by Aave. According to PeckShieldAlert, over 600 addresses received 0.1 ETH from Tornado Cash 0.1 ETH contract.  Other decentralized protocols including Uniswap, Balancer within the DeFi ecosystem had also blocked Tornado Cash-funded accounts.

How did the Addresses get Blocked?

On August 14, Aave announced that the protocol received blockchain intelligence from TRM Labs and integrated TRM API into its frontend to ensure a safe and secure system. The decentralized protocol said that after The Office of Foreign Assets Control’s (OFAC) sanction decision on Tornado Cash, the team integrated TRM’s API, which screened and blocked any address that interacted with the Tornado Cash contracts post-sanction. Aave wrote,

“This explains why the API may have made incorrect calls about which wallet should be included in block-lists, in this case including those wallets that were sent “dusted” ETH by third parties interacting with the Tornado Cash contracts without consent.”

As per the announcements, the Aave team addressed the issue assuring to evaluate responsible and reasonable risk mitigation according to the circumstances. However, the protocol reiterated that it continues to remain decentralized and governed by a decentralized organisation (DAO), urging its “community to remain engaged and actively fight for open and fair finance.” Aave specified,

“The Aave team will continue to innovate. We encourage the community to remain engaged and actively fight for open and fair finance.”

Sanction Slapped on Tornado Cash

In the meantime, Justin Sun, whose Aave account was one of those blocked for receiving $0.1 ETH through Tornado Cash, confirmed that the account is active again. On August 13, the Tron founder, tweeted that he was unable to interact with Aave revealing that that the decentralized protocol had blocked his wallet because of a Tornado Cash-linked transaction.

Earlier this month, The United States Treasury Department, had slapped sanctions on virtual cryptocurrency mixer, Tornado Cash, charging the platform of money laundering, that cybercriminals used to siphon nearly $7 billion in crypto. OFAC has already listed Tornado Cash to its Specially Designated Nationals list, a register of blacklisted people, entities and cryptocurrency addresses.
