Additional precautions will be adopted, according to Shevchenko, to ensure that such cost of an assault rises. He also revealed the attacker’s address, who began with some ETH supplied using Tornado Cash. The attack started on May 1, when the attacker used a contract to deposit money in order to become a Rainbow Bridge relayer. The plan was to send out fictitious light client blocks.

One of the bridge protectors eventually recognized the submitted block wasn’t on the NEAR Protocol blockchain then sent a challenge transaction to Ethereum. Shevchenko notes in his tweet that as a consequence, the watchdog transaction failed, the MEV bot transaction succeeded, and the perpetrator’s faked block was scaled back. Their relayer then uploaded a fresh block a few minutes later.
