A Commons bridge hack drained 18.5M SYND tokens worth $330K. Here’s what happened, who’s affected, and what Syndicate is doing next.
A security exploit struck the Syndicate protocol’s Commons bridge on the Base chain. Attackers used a privileged upgrade flaw to drain approximately 18.5 million SYND tokens.
The stolen tokens were worth roughly $330,000 at the time of the attack.
The thief quickly converted the tokens into ETH on Aerodrome, a Base chain decentralized exchange. Proceeds then moved to the Ethereum mainnet, complicating recovery efforts.
