mevEth - MVP Testnet

[ControlCplusControlV]

Minimum Requirements for mevEth given updated business requirements, and a now fully fleshed out design in mind which should be final.

LayerZero Requirements

• Inherit OFT v2 + move over tests from that repo to allow OmniChain Usage #37
• Fee on bridge event outside of L2s? #33
• Find some way to test multichain functionality? #36

MevShareVault

• Test with multisig as initial version of MevShareVault #39
• MevShareVault should accept payment from feeTo minting and mevPayments, which both generically work to increase its balance (although should be accounted for separately, feeTo is anything from block.coinbase, all else is MevPayment) #31
• MevShareVault should determine a median block reward amount, and a median mev payment, both of which should be tracked in some index-able way, similar to a TWAP #28
• MevShareVault should have an operator-only function to grant its rewards to mevEth, boosting its numerator value only #32
• MevShareVault should have configurable fee parameters, and charge a fee of any outlier Mev Payments #29
• MevShareVault is incomplete #30

Accounting

• Remove the word "Rebase" from the codebase, should instead use generic terms like "Fraction", "Numerator," and "Denominator" instead of "base," and "elastic" #48
• Address calculateNeededEtherBuffer() to fetch a max between a configurable % of total stake or a max of 31 ether #51
• Minimum Denominator amount should be enforced by requiring a 1 finney burn at contract creation, minting to the 0 address #40

Withdrawal Queue

• - Implement withdraw / redeem queues #27

Tracking Validators

• Ensure parity with the old ValidatorRegisttry contract, and that the same data is tracked #21
• - createValidator should emit an event #22
• - Method oracleUpdate on WagyuStaker not called #17

Upgrades

• Test upgrading staking module from dummy contract to Wagyu, ensure it works #38
• Test upgrading from Multisig to MevShareVault #41
• withdraw / redeem admin controlled pause flag #34

*Integration (in order strictly)

• Test WagyuStakingModule, MevShareVault, and MevEth deployment locally on mock consensus layer via nix #15
• Test WagyuStakingModule, MevShareVault, and MevEth deployment on Goerli with gETH validators #14

Docs

• - Make arch diagram
• - Make sure each contract has full natspec for each function

*Finishing Touches (in order strictly)

• - Any cool anscii art?
• - Fix README for auditors
• - 100% test coverage
• - Look for gas optimizations
• - Run slither + other static analysis
• - Format rules
• - Run through solcurity checklist
