Summary

• Route full bid amount through ShMonad sendValidatorRewards
• Apply ShMonad protocol fee (10%) via PROTOCOL_FEE_RATE
• Remove direct MEV split/coinbase tip in auctioneer

Example 10% ShMonad fee (feeRate = 10%)

Assume:

• MEV amount = M
• ShMonad feeRate = f = 10%
• Coinbase mevCommissionRate = c

Flow:

Auctioneer
  └─ sendValidatorRewards(M, f=10%)
       ├─ Protocol fee (ShMonad revenue): M * f
       └─ Validator payable (escrowed):   M * (1 - f)

On validator crank:
  └─ handleMEVPayable(value = M*(1-f))
       ├─ Coinbase commission: M*(1-f)*c
       └─ Coinbase rewards:    M*(1-f)*(1-c)

Example with M=100, f=10%, c=20%:

• ShMonad fee: 10
• Validator payable: 90
• Coinbase commission: 18
• Coinbase rewards: 72
