ReferralGateway: On-chain referral infrastructure for EVM products

Hi Product Hunt — I’m Maleev Evgeny, building ReferralGateway with the NineLab team. We kept seeing the same pattern in Web3: teams want a referral or affiliate program with transparent payouts, but end up with spreadsheets, manual USDT transfers, or a half-finished Solidity repo that never reaches mainnet. ReferralGateway is the stack we ship to clients: a Solidity contract on EVM, a Go API with indexing, and Next.js dashboards for referrers, sellers, and admins. Sellers publish offers; referrers share links; buyers pay in ERC-20; rewards are split and claimed on-chain. Hold periods and dispute flows are built in so payouts are not instant by default. What to try today: live demo on Sepolia — https://dr.ninelab.ru/ Connect a wallet, browse offers, and walk through the referrer and seller flows. Technical overview and case study: https://ninelab.ru/en/cases/bloc... Who this is for: Web3 marketplaces, DeFi products, and integrators who need white-label referral infrastructure — not a generic CPA network dashboard. We’d love your input: Would you deploy this as-is, or only as a reference architecture? What’s missing for your stack: multi-chain, RBAC, or fiat off-ramp reporting? If you’ve built referral on-chain before, what broke in production? Happy to answer questions about the contract model, gas, ops, or licensing. Thanks for checking it out.
