What Usher is

Usher is an open-source platform for managing performance-based referral partnerships in Web3. Brands can set web actions or smart-contract events as campaign conversions, then track referrals and reward partners when those events occur. Partners share invite links and earn campaign rewards for qualifying referrals. Rewards can be flat or percentage-based, paid in ETH, MATIC, a brand’s own token, or an NFT. The platform describes campaigns for NFTs, Web3 infrastructure, digital wallets, decentralized finance, metaverse projects, and gaming. Usher says it is sunsetting operations for Usher Referrals, but makes the project code available for self-deployment under the GPL-3.0 license. The repository describes a Next.js web app and an optional blockchain listener, with Ceramic, ArangoDB, and Humanode Sybil resistance with OAuth among its components. Operators are responsible for encrypted wallet private keys stored in their database; decentralizing funds management was described as planned. Usher Labs provides a contact form for guidance on use cases, integration, and technical needs.
