feat(interop): superchain backend

3

This contains the start of the backend for superchain interopability. This backend exposes a single endpoint `superchain_messageSafety` that will verify that the message identifier matches the supplied payload and returns...

The indexer is in a mature state. Some followups: 1. The default indexer configuration in the repository should be setup for the local devnet. 2. The docker-compose should include a...

Closes ethereum-optimism/optimism#10890 Introduces a general abstraction, `OptimismTxPoolPolicy` that layers over the transaction pool and applied 3rdparty validation logic prior to txpool submission. The only implementation of this abstraction with the...

feat(engine.queue): consistent safe head progression on failures

3

We can simplify derivation by having the pipeline always ensure safe head progression when processing payloads pulled from L1. 1. Always Valid (empty deposits-only block) 3. A proper L2 block...

feat: eth_sendRawTransactionConditional

8

Closes ethereum-optimism/ecopod#1024 Sequencer implementation of `eth_sendRawTransactionConditional` described in this [design doc](/ethereum-optimism/design-docs/blob/main/ecopod/sendRawTransactionConditional/proposal.md), refreshed from @tynes initial [draft](https://github.com/ethereum/go-ethereum/compare/master...tynes:go-ethereum:eip4337) ## Design Doc Divergence Rather than exposing a separate port to expose the sequencer...

expose http headers & request body via peerinfo context

1

go-ethereum library has very useful rpc libraries for creating json-rpc servers, used extensively in the optimism monorepo. For the [sendRawTransactionConditional](https://github.com/ethereum-optimism/design-docs/blob/main/ecosystem/sendRawTransactionConditional/proposal.md) endpoint, we want to implement authentication external to the the...

Validation script should use the OptimismMintableERC20 interface

3

Surfaced in #915 L2StandardERC20 imported [here](https://github.com/ethereum-optimism/ethereum-optimism.github.io/blob/master/src/validate.ts#L227) is an outdated interface. L2 tokens just implementing the `IOptimismMintableERC20` interface should be compatible with the validation script without needing to implement the legacy...
