Pay-on-sale referral marketing
Pay creators only when they sell.
Publish an offer, set a commission, and let creators share it with their audience. Every buyer payment is held in escrow and, once the refund window closes, released in a single step that splits it between you and the creator. No invoices, no chasing payouts, no paying for clicks that never convert.
- Escrowed on NEAR
- Refund window for buyers
- Low cost for creators
- Payouts across chains
How it works
From offer to payout in three steps
Publish an offer
Describe what you sell in one sentence. Our assistant drafts the price, commission and refund window. You review the terms and publish from your own wallet.
Creators share their link
Creators claim a unique referral link in a few seconds and share it with their audience.
Everyone gets paid
Buyers pay into escrow. When the refund window closes, the payment is released and split between you, the creator and a small service fee.
For businesses
Grow sales without paying for reach
- Pay only for results. Commission is taken from completed sales, never from clicks or impressions.
- Refunds stay in your hands. Refund a buyer in full at any point before the refund window closes.
- Launch in minutes. Describe your offer in a sentence and get a ready-to-publish draft.
- Every sale on record. Payments and splits are public and verifiable.
For creators
Get paid for every sale you drive
- Your own referral link. Claim a link for any offer and share it anywhere.
- Free to join. No sign-up fee. Claiming a link costs only a tiny network fee.
- Locked-in split. Your commission is recorded with each sale when the buyer pays and paid out by the contract, not by an invoice.
- Payouts your way. Get quotes to receive your earnings on other chains.

Simple, transparent fees
service fee per completed sale. No listing fees, no monthly plan, and refunded sales cost nothing. You set the creator commission yourself.
Example: a 100 tUSDC sale with a 10% creator commission
- Seller 88 tUSDC
- Creator 10 tUSDC
- Service fee 2 tUSDC
Technical details
The split is calculated and paid by a smart contract on NEAR. Both the creator commission and the service fee are taken from the sale amount; the rest goes to the seller.
Service fees are paid to referrail-demo.testnet.
Claims made without a wallet can be sent as sponsored transactions, so the network fee is covered by the app. Cross-chain payout quotes come from NEAR Intents and are estimates until you confirm them.
FAQ
Questions, answered
Is my money safe?
Buyer payments are held by a public smart contract on NEAR, not by ReferRail. The contract only pays out according to the offer's terms: the full amount back to the buyer on a refund, or the agreed split once the refund window closes. You can inspect the contract at any time.
ReferRail is currently running on the NEAR test network, so only test tokens are involved.
What happens if a buyer asks for a refund?
Each offer has a refund window. Until it closes, the business can refund the buyer in full and nobody is charged a commission or fee. After the window closes, the payment is split and paid out.
Do creators need crypto?
Creators need a NEAR account to receive earnings. They don't need to buy the offer's token, just enough NEAR to cover a tiny network fee when they claim a link.
Which tokens are supported?
Offers are priced in tUSDC, a test stablecoin used on the test network. Creators can also request quotes to receive their earnings on other chains.
What does it cost?
A 2% service fee on each completed sale. There are no listing fees or subscriptions. Businesses pay a small NEAR network fee when they publish an offer; claiming a referral link costs creators only a tiny network fee.
