I personally think no one can keep up with Patrick's speed. Patrick is Co-founder, Defi Educator, Smart Contract Developer, Web3 security researcher and educator, KZbinr etc. The energy is just off the charts.

[@gunnerandersen4634]

Awesome video (still on it) I'll post/update my question/s 1 why not use roles over owner contract to map owner, entry point contract address and any others ?

[@PatrickAlphaC]

we could do that!

[@musprodev]

Been waiting on this 😅

[@dangelgeek]

WAO!, this is awesome!; thank you very much! Now I understand better how to implement and use AA-4337 with Solidity. At some point, are you thinking of implementing something like that with Rust?

[@PatrickAlphaC]

@@dangelgeek awesome!! And probably not in the near future

[@dangelgeek]

@@PatrickAlphaC I try to test it on sepholia but I gave me errors when run the SendPackedUserOp.s.sol, look like the EntryPoint code is different? or the problem is other, also in the video you mention I can't be possible?

[@PatrickAlphaC]

@@dangelgeek you probably didn’t change the entry point contract address?

[@justiceessiel6123]

@2:03:43 I see we used config.account of which we stated that if we are working locally we use the anvil signer but then is that not the right signer for the userOps..we changed that to the minimal account

[@PatrickAlphaC]

@@justiceessiel6123 what’s the question?

[@codertjay]

the legend is here

[@patricioibarrag]

@patrick As I understand this works for all EVM blockchains, correct? Do you know if is there something similar for Solana, Cosmos, or other non EVM blockchains!

[@PatrickAlphaC]

Correct! This is for EVM only! There is a type of account abstraction on chains like Solana, and technically you could do it since day 1 of Solana, but I'm not sure how well adopted it is.

[@patricioibarrag]

Thanks,@@PatrickAlphaC. Is there any chance you can share how to find more information on this for Solana and Cosmos?

[@PatrickAlphaC]

@@patricioibarrag I’m not aware of such information, sorry. I think a lot of it you’d have to pioneer.

[@patricioibarrag]

Thanks @@PatrickAlphaC!

[@BigPaulean]

The Problem: Some people find managing a keypair to be too complex and confusing. The Solution: Let's implement a process that is too complex and convoluted for people who DO know how to manage a keypair so that no one can easily interact with smart contracts.

[@PatrickAlphaC]

@@BigPaulean pretty much lol. Make engineers lives harder so that non-tech people can have easier lives

[@BigPaulean]

@@PatrickAlphaC This is great content though, I appreciate it. Everyone has been talking about 4337 since 2024 started or so...this is the first easy-to-follow deep dive that exists as far as I know though :). This process will definitely need to be systematized (and implemented on testnets!).

[@BigPaulean]

Hey I was just thinking: would you consider these alt mempool nodes to be a sort of competitor to Chainlink Functions DON nodes? They seem to have a similar utility of updating onchain state based on some offchain logic…

[@PatrickAlphaC]

@@BigPaulean yes! In some regards I would!

[@LevisTovi]

From the example, I'm not sure how to use a Google Account (as an example) to sign the transaction without a crypto wallet on the user side. Do I need a backend service that takes user input and uses it to sign and send the transaction to the EntryPoint contract? Do you have or know of a complete example (with UI) that implements this without the user needing a crypto wallet? Thanks.

[@PatrickAlphaC]

@@LevisTovi yes - you’d need to generate a Google session key and use that to sign transactions, and then a service that asks Google if the tx is legit signed by a session key. Or you could do something clever with public private session keys. So the Google key thing would require more engineering than what we do here, this is the bare bones skeleton

Is it possible to deploy on EVM base private blockchain. Thank you in advance

[@PatrickAlphaC]

@@sagarkarmoker4517 yes - but private blockchains are lame. Unless you’re talking about a public blockchain with privacy features -> that is cool

[@codeWithBala]

"Could you please explain why AA was tested on the main net, considering we don't have entrypoint contracts available on testnets?

[@PatrickAlphaC]

@@codeWithBala it was tested on testnets, but alt-mempool node just don’t think it make sense to spend resources servicing testnet requests since they aren’t paid for them! It can be very hard to run such services for free

[@acanaldelbuencontenido]

@@PatrickAlphaC so there's no way to test AA in Sepolia for example or how can I test an AA project on Sepolia or Arbitrum Sepolia? Thank u genius

[@PatrickAlphaC]

@@acanaldelbuencontenido not really. You’d have to find alt-mempool nodes that run on sepolia. I’m not aware of them. There could be.

[@acanaldelbuencontenido]

@@PatrickAlphaC But when you set the rpc url for Arbitrum, how did you know it was an alt mem pool node or is there a process behind to detect that it is a ERC4337 transaction and it is derived to the alt mem pool by this rpc url node you gave? Thank you for your time.
