An Optimistic Build

I missed the first half of this talk

About building/deploying on Optimism L2

By Justin J. Moses @justinjmoses

Contract Management Gotchas

• block size is 24kb
• no selfDestruct
• uses wETHA

Deployment

• no gas price or limit because the L1 is unknown

Testing

• unit testing doesn't change (can still use hardhat for example)
• integration:
  • L1 tests using geth
  • L2 using geth OVM
  • combined uses both nodes

Ownership

• multisig can live on L1
• messages relayed into L2
• avoids multisig on L2 (helps move across L2 without moving the wallet around)
