[cgewecke]

DO NOT MERGE: TARGETS #81

  • Figure out test selection strategy for both clients (since some tests will only succeed on OVM)
• Get critical tests passing on Optimism client in CI
  • Add revert helper
  • SetToken
  • BasicIssuance
• Add L1 -> L2 Eth deposits f5d3c88
• Publish built docker images to SetProtocol github packages account 37b37e2
• Add installation instructions / script for local development 6dc1c33
• Normalize library function signatures for external calls (e.g no IERC20 data type) and clean up contract changes
• Fix eth-optimism core-utils tsc error on build 4d6cff5

Should go after call.

Actually, need to investigate how value gets compiled down...current order might be right.

Also double check current Optimism's client's management of this to see if necessary.

Closing for the moment ... will revisit when support for Optimism is scheduled.
