We're bringing native interoperability to the Superchain this year. This means low-latency, fungible, and portable assets across chains. 

Two pieces to enabling this are the message passing protocol and the token standard. 

We're looking for feedback on the token standard, let us know what you think. Link below!

We could add an execute instruction after the mint ? I think it should be added as it may reduce txs for users

Agreed, because there's an initiate tx and finalize tx we're planning to work with relayer services so from the end user perspective it just feels like 1 tx :)
