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)

  1. Go to the USDT contract on Etherscan.
  2. Click Connect to Web3.
  3. Find the approve function and set: 
    _spender: 0xa4994144a9217e3779bDa588798EfF546b69DEfB
_value: 0
  4. Click Write and sign in the MPCVault app.
Retry the batch payment after the revocation confirms.
