I read the specs of ERC-6551 and am missing the gap to ERC-4337.

ERC-6551 seems to be based on ERC-4337 according to various sources on the internet and the general terminology, but the specs do not mention 4337 at all and there seems to be no footprint of the reference account implementation.

My questions are:

  1. Is there a connection between ERC-6551 and ERC-4337 at all?
  2. How is that wired? At some point I'd need to specify an entrypoint etc. for the accounts created via the registry in ERC-6551.

  • Thank you for asking, I've seen similar threads floating around on Twitter and no hard evidence :). My guess is that ERC6551 wallet implementations can conform to ERC4337 but that they don't need to as per the standard.

=> No. There's no direct connect between 6551 and 4337.

6551 meres acts as a registry for the contracts created using the details of the ERC721, where as 4337 defines the flow of a txn using UserOPs, Paymasters, and Bundlers to provide a good UX.

You can deploy Smart Account (4337 enabled Smart Contract) using your ERC721 details, and 6551 will store the address of it.
