Rewards and the MEV split

Understand the ordinary baseline, gas coverage, standard 60/40 split, and Vouch fee-depositor rebate.

The ordinary reward comes first#

The validator receives the ordinary block’s baseline reward before added MEV is shared. BlockFerret’s share comes from value added above that baseline, after costs. Ordinary priority fees are forwarded to the validator; they are not divided 60/40.

What counts as net added MEV?#

Gross arb or protocol proceeds are reduced by the builder’s execution gas, the validator payment’s gas, and ordinary fees displaced by the candidate. Returned borrowed principal is not profit.

Accounting

Net added MEV = gross capture
              − execution gas cost
              − payout gas cost
              − displaced ordinary fees

This accounting covers the builder’s measured gas costs before profit is split. A candidate that has no sufficient net surplus cannot justify a MEV share.

Standard proposer: 60 / 40#

The validator receives 60% of net added MEV. BlockFerret retains 40%. The ordinary baseline is paid in addition to the validator’s MEV share.

Illustrative amount	PLS
Ordinary baseline reward	1,000
Gross added capture	600
Execution gas + payout gas + displaced fees	100
Net added MEV	500
Validator’s added share: 60% × 500	300
Validator payout: 1,000 + 300	1,300
BlockFerret retained: 40% × 500	200

Vouch fee-depositor rebate#

For an eligible Vouch validator fee-depositor proposer, BlockFerret also returns half of its standard retained share through the bid’s validator payout. Half of the 40% builder share is another 20% of net added MEV.

The resulting share is effectively 80% to the validator and 20% retained by BlockFerret, in addition to the ordinary baseline. The rebate is included in the block payment rather than requiring a later manual transfer.

What a wallet user pays#

The base fee is burned by the network. The effective priority tip contributes to the validator’s ordinary reward. There is no separate BlockFerret wallet service fee, and this RPC does not automatically increase your fee settings.

You pay for gas actually used when your transaction is included. A transaction that is never included does not incur on-chain execution gas.

Independent builder submissions#

The standard split describes BlockFerret’s own captures. Independent complete-block submissions follow separate payment gates; the builder does not automatically take 40% of an outside builder’s entire profit.
