AA20 account not deployed

AA20 account not deployed is an ERC-4337 EntryPoint error that means the user operation has no initCode but its sender smart account is not deployed yet.

An initCode was not specified, but the sender address (i.e. the smart account) is not deployed.

Possible solutions

• If this is the first transaction by this account, make sure the initCode is included in the user operation.
• If the smart account is already supposed to be deployed, verify that you have selected the correct sender address for the user operation.
