  • Found a good library to work with to sign eth txs using Google KMS
  • Built a POC to sign and send read txs in base, sepolia and op
  • The library supports only legacy tx types so I made a PR to add EIP1559 used by batcher and proposer. The PR is missing EIP4844 tx which is a blob tx. I think we need to support it eventually but the library used for tx manipulation (@ethereumjs/[email protected]) doesn’t support blobs within its minor versions. They added it in 5.x but they also broke ABIs. I made necessary changes in a branch but testing them have been tricky so I am gonna wait to see how the author responds to my PR.
    Next step: create a server to accept http requests to sign txs. Test it with a batcher or proposer from Optimism.
