Phase 2 for Sponsoo: smart contracts that pay athletes once deliverables are verified
In a second project for Sponsoo, we built Solidity smart contracts with an Oracle that validates deliverables, automating the deal from contract signing to athlete payout.
The Challenge
With the marketplace live, Sponsoo's sponsorship agreements still depended on manual steps between signing and payment. Sponsoo wanted the terms on its platform enforced automatically.
The Approach
In this second phase, we wrote the sponsorship contracts as Solidity smart contracts, which are immutable, transparent and distributed. We implemented an Oracle that validates deliverables automatically, so the whole process from signing the contract to paying the athlete runs without manual steps. We used Hardhat for development and testing, Ethers.js to interact with the blockchain and Metamask for wallet integration. Figma supported design collaboration.
The Results
Contract terms between brands and athletes are now enforced automatically and transparently for both sides. Payments go out only when the Oracle confirms the deliverables, which reduces administrative overhead. Sponsoo can now settle sponsorship deals on its platform from signature to payout with far less manual work.
