I created a TS library for sending ERC-4337 user operations, currently supporting Kernel and Nexus, designed to work with ethers.js. Feedback is welcome! https://github.com/ethaccount/sendop

1. 7702 and 4337 are not mutually exclusive. The best way to use 7702 is adding 4337 validation to the EOA. It gives you gas abstraction without extra code - just use existing paymasters. And censorship resistance is baked in. 2. EOA+7702 will remain less secure even if we add an opcode to revoke the ECDSA key. Any ERC20 that supports `permit` trusts the old key. The EOA also remains valid on other networks so the original key still has power. 3. Post-quantum we'll switch to quantum-safe validation such as Falcon, using AA. An EOA always has the additional ECDSA key and has already published one signature (the 7702 tuple), hence it'll be vulnerable to quantum attacks even if it upgrades its code to use a quantum-safe sig. If you care about quantum safety (which you should if your account is meant to be long-term), avoid EOA. 4. The one reason to use 7702 is when your EOA already has assets that are a hassle to transfer, or non-transferable such as reputation. For new accounts I'd consider an AA-only account.

I got it after the end of Richard’s talk. Maybe you can reach out to him!

Most web3 tools are made for React, but very few for other major frameworks such as Vue. This is why I think we should support libraries like Vue Dapp made by @johnson86tw. They bring more diversity to the web3 frontend dev space. Consider donating to Vue Dapp here: https://explorer.gitcoin.co/#/round/42161/609/21

I have a quick idea about ZK password AA validator. I want to build a signature validation module by implementing a validateSignature function with Circom, which is simply a Poseidon hash (input: secret, output: commitment). If a smart account installs this module, storing the commitment on-chain during installation, the smart account could then use a user-defined "password" to submit user operations and initiate any transaction. Is this idea feasible?

I played badminton in high school until I discovered tennis XD. it's hard to play outdoors because the ball can be affected by the wind, but it's really fun!

The biggest problem I have with passkeys in crypto is that it fails the walkaway test because it’s tied to a domain Is this solvable?

In the future, we might need an interface to manage any smart account from various AA venders, such as sending txs or installing erc7579 modules, instead of being limited to the interface provided by the AA vendor's app or dashboard, for greater control over our smart wallet.
