AA93 invalid paymasterAndData

AA93 invalid paymasterAndData is an ERC-4337 EntryPoint error that means the user operation's paymasterAndData field is set but too short to hold a paymaster address.

The paymasterAndData field is of an incorrect length.

Possible solutions

  • Make sure you have either not set a value for the paymasterAndData, or that it is at least 20 bytes long.
  • If you are using a paymaster provider like Pimlico, reach out to them.
