The current PR for 1559 from geth -- ethereum#22896

Mev-Geth Tasks:

• Investigate if Ethers handles 1559 encoding for tests (T/J)

• figure out how running eip-1599 in a local test net even works, ie. can we easily control the basefee in the header (T/J)

• update end to end tests to use eip-1559 tests (T/J)

  • Make sure we enable the london fork

• mev-geth load test - update to support 1559 (T/J)

• Add test cases for consensus changes:

  • There is a new rule added friday, we may need to check that things work,
  • sender balancer is greater than maxFeePerGas*gasLimit
  • priority fee per gas <= max fee per gas

• add test for bundle with a tx below the block header basefee

• update sponsored tx to rely on pre-inbound eth instead of post-payment of 0-gas-price (J)

• eth_callBundle updates (J)

  • Update gas price
  • Use new fee tip
  • Check base fee

Relay Changes:

• Almost nothing should need to change here.
• Update the hard cutoff for gas price (gasnow endpoint, hardcoded value)

Not mev-geth:

• Update blocks api
• Survey miners and asking if they're planning on moving forward with EIP1559 (Tomasz/Tina?)
  • Is there anything they require us to deliver?

Timeline:

• Original geth timeline was pushed because of a consensus, so Friday the 11th the timelines will be decided on.
• For our planning
• 14/15th a likely date first testnet to exist -- could be delayed.
• 15th of July is earliest date for mainnet
• Goerli Date ~~ 23rd of June

Testing:

• Been relying on end-to-end tests
• Could revisit trying to do more unit test -- it's very complicated
• Investigate connecting mev-geth as a validator to Calaveras (end to end)

Discussion Future Notes:

• Add better End to End testing Structure
• Research: Are there efficient ways to capture value by arbing between legacy and eip1559 txn

Yes,

The implementation changes here -- https://github.com/flashbots/mev-geth/tree/release/v1.10.4-mev0.3. This has been deployed to Goerli and has been running since the Goerli switchover to london.

Newest branch is based on upstream v1.10.5, https://github.com/flashbots/mev-geth/tree/release/v1.10.5-mev0.3. Also it has been pushed to master.
