spent some time updating my script for recovering funds sent to coinbase smart wallets on chains not supported by the base account app to add passkey signing support
used it to successfully recover funds on monad e.g. https://monadscan.com/tx/0x8486ce008224fcc5dd19f8c90605a0b08237b9d10539999a0a2bd2d80859d022
disclaimer: this script is not affiliated with coinbase / base. use at your own risk
