AA14 initCode must return sender

AA14 initCode must return sender is an ERC-4337 EntryPoint error that means the initCode deployed a smart account at a different address than the user operation's sender.

The address of the smart account deployed with the initCode provided does not match match the sender address provided in the user operation.

Possible solutions

  • Verify that the sender address was generated deterministically from the initCode. (consider leveraging functions like getSenderAddress)
  • Verify that the factory address in the initCode is correct (the factory address is the first 20 bytes of the initCode).
  • Verify that the initCode is correct.
  • If all else fails, investigate why the initCode deploys to a different address than expected using tools like Tenderly.
