Become an ISO partner.
In the payments trade, this is called an ISO — an independent sales partner. A share of the margin, paid in stablecoins on Base. Open to U.S.-registered entities at this stage. We never ask for a tax ID: your commission settles on-chain from the merchant's settlement contract, so Zoyn is not the payer and has no tax identifier to collect.
Commission terms
The ISO partner program is open to U.S.-registered entities at this stage. We cannot accept applications from entities registered outside the United States yet.
Approval links your application to a Zoyn account with the same email address. Make sure a Zoyn account exists for the contact email you give below — sign up with that address first if you don't have one yet. An application with no Zoyn account behind its email cannot be approved.
You earn a share of the margin above each assigned merchant's fee floor — the part of their Zoyn fee that sits above the floor agreed on their deal — paid to your wallet on-chain, in stablecoins on Base, at the same moment the merchant is paid. The exact percentage is set when your application is approved.
Your commission is written into each referred merchant's on-chain settlement contract as your own share, so the contract pays you at the same moment it pays them — directly to your wallet, in stablecoins on Base. No fiat, no invoicing.
Zoyn never holds or forwards your commission; funds flow from the settlement contract to your wallet.
Wallet changes require Zoyn approval and a security hold — typically 72 hours, set when the change is approved. New merchant settlement contracts then pay the new wallet; contracts already deployed keep paying the old one until we redeploy them, and we tell you which are still outstanding in your ISO portal.
