To start earning
Grab a builder code at base.dev, then add one line to the x402 client you pay MiroShark with:
Every run you drive then pays you 10% automatically.

Send MiroShark paying users and you earn a cut of every run, paid straight to your wallet on Base. This page shows each builder's share and what's still waiting to be paid out.

How the payout works
Attribution rides along with the payment itself. When your client settles a MiroShark run over x402, your builder code travels in the payment as the service code, so the split contract on Base credits your address at settlement time. There is no dashboard to sign up for, no referral cookie, and nothing to reconcile later - the accounting is the transaction.
Balances accumulate per builder and are released on demand. Payouts settle in USDC on Base, and the split percentages are fixed in the contract, so a release always divides the balance the same way - down to a couple of base units of dust the contract keeps to stay solvent.
The funds sit in an immutable 0xSplits PushSplit contract on Base until someone triggers a release. That call is permissionless - anyone can send it, it costs only ordinary Base gas (cents), and it can only move the balance the contract already holds out to each builder's own address. Nobody, MiroShark included, can redirect where a share lands.
How it works
The split is enforced by the chain, not by us.
Nobody owns the account your share lands in - not even MiroShark. Nothing about a split can be edited once it exists, by us or by anyone else, so there is nothing here you have to take on trust. It's the same open-source kit any x402 seller can run.
