Error AA20: Account Not Deployed

Resolving issues when the sender account is not deployed

No initCode was specified, but the sender address (smart account) isn’t deployed.

Potential Fixes

1. For first-time transactions, include initCode in the user operation
2. If the account should already exist, double-check the sender address in the user operation

Ensuring the correct deployment status and address of the sender account will resolve the AA20 error.
