Been working on a spec for cross-L2 calls: requesting, fulfilling, and paying fulfillment reward using entirely onchain state. https://github.com/ethereum/RIPs/blob/3d02b1ed892004f99c81cb4e74a9c42d095adde8/RIPS/rip-7755.md PR here https://github.com/ethereum/RIPs/pull/31 Discussion here https://ethereum-magicians.org/t/rip-7755-contract-standard-for-cross-l2-calls-facilitation Appreciate feedback!

"Using these inputs, on any Ethereum L2, we can trustlessly verify ERC-1183 storage proofs of any other Ethereum L2." Does this mean the verification could only happen after transactions being sent from L2 to L1 in the destination chain? Would that imply a long time before the cross-chain tx could be confirmed?

not just that: you'd have to wait for the state root on L1 AND for the challenge period to conclude. I.e. probably 7 days right now for the fulfiller to get paid
