AA24 signature error

The validateUserOp function of the smart account rejected the signature of the user operation.

Possible solutions

  • Verify that the user operation was correctly signed, and that the signature was correctly encoded in the signature field of the user operation.
    • Most smart account implementations sign over the userOpHash. Make sure that the userOpHash is correctly computed. Consider leveraging functions like getUserOperationHash from viem/account-abstraction.
    • Make sure you have selected the correct chainId and entryPointAddress when computing the userOpHash.
    • Make sure the smart account signature verification function is correctly implemented.
  • If all else fails, investigate why the validateUserOp function rejected the user operation signature using tools like Tenderly.
