$3.3M in ETH Drained From SushiSwap Approval Contract
The blockchain security resource PeckShield was the first to inform about the exploit against SushiSwap’s approval contract.
According to the firm, all 1,800 ETH (worth about $3.3 million) were drained from a single user – @0xsifu.
- The “RouterProcessor2” contract in question is used to execute trade routing on the popular decentralized exchange.
It seems the @SushiSwap RouterProcessor2 contact has an approve-related bug, which leads to the loss of >$3.3M loss (about 1800 eth) from @0xSifu.
If you have approved https://t.co/E1YvC6VZsP, please *REVOKE* ASAP!

- Jared Grey, SushiSwap’s head developer, also weighed in on the matter, outlining the “approval bug” and advising users to revoke the approval as soon as possible.
- Additionally, Grey tried to caution the community by noting that the team behind the DEX is working on finding a proper solution.
Sushi’s RouteProcessor2 contract has an approval bug; please revoke approval ASAP. We’re working with security teams to mitigate the issue. https://t.co/WhXJfa5xD4
