[enitrat]

See https://github.com/kkrt-labs/kakarot/blob/7fb90d799a5a0bfab0a48bdfcb4e867d35b4943c/src/kakarot/accounts/account_contract.cairo#L83

Can I work on this ?

Some info I found:

• SNIP-9 : https://community.starknet.io/t/snip-outside-execution/101058
• Argent implementation: https://github.com/argentlabs/argent-contracts-starknet/tree/main/src/outside_execution

Hey @remybar!
Thanks for showing interest.
We've created an application for you to contribute to Kakarot zkEVM.
Go check it out on OnlyDust!

[enitrat]

yes, and the reference implementation in Cairo Zero: https://github.com/kkrt-labs/kakarot/blob/7fb90d799a5a0bfab0a48bdfcb4e867d35b4943c/src/kakarot/accounts/account_contract.cairo#L83.

First try to migrate to a SNIP-9 compatible structure. For everything that can not trivially implemented, add a TODO and we'll create an issue.

@remybar how are things going?

Hi @enitrat
We finally took some holidays until end of August so I'll be back to work on issues end of August/beginning of September.

Do you need this feature earlier than that? If yes, I can push what I did if someone wants to continue.

[enitrat]

yes please!

[remybar]

yes please!

I pushed what I've started in the following PR #836.

Sorry for the delay, I don't like to start a task and let it for several days/weeks 😕
