USDT/CRV Authorization Issues
Some tokens (USDT, CRV) require revoking existing approvals before setting a new amount. This is an on-chain action that incurs gas fees.
Revoking USDT Approval (Ethereum)
- Go to the USDT contract on Etherscan.
- Click Connect to Web3.
- Find the approve function and set:
_spender: 0xa4994144a9217e3779bDa588798EfF546b69DEfB
_value: 0
- Click Write and sign in the MPCVault app.
Retry the batch payment after the revocation confirms.
