the contract for vote-locked CVX (vlCVX) has been re-deployed. Convex Finance was recently made aware of a potential bug in the vlCVX rewards system. This bug was responsibly disclosed before anyone utilized it; no loss of funds occurred, and user deposits were not at risk.

User’s who vote-lock CVX earn 5%+1% rewards in the form of cvxCRV. This bug made it possible for expired locks to relock directly to a new address, which, in turn, enabled them to claim more cvxCRV rewards than they had earned.

This was a near miss.
