Yieldproof
YieldProof is a trustless DeFi protocol that cryptographically verifies real-world asset yield on-chain and enforces transparent, automated distribution using smart contracts and economic incentives.

Description
YieldProof is a DeFi protocol that brings trustless, on-chain verification to real-world asset (RWA) yield, solving a critical gap in today’s RWA ecosystem.
While RWAs are increasingly tokenized on-chain, yield reporting and distribution remain off-chain, opaque, and trust-based. Investors must rely on issuer claims, delayed audits, and manual processes, creating risk, misreporting, and capital inefficiency.
YieldProof introduces a cryptographic yield verification and enforcement layer that ensures issuers can only distribute yield that is provably earned.

Progress During Hackathon
During the hackathon, the YieldProof team designed and implemented a fully functional MVP that demonstrates end-to-end, trustless yield verification for Real World Assets. Protocol Design & Architecture Defined the core protocol architecture separating capital custody, yield verification, and distribution enforcement Designed a zero-trust yield disclosure model using economic incentives instead of issuer trust Formalized issuer, investor, and attestor roles with clear responsibility boundaries Smart Contract Development Implemented Solidity smart contracts on Mantle Sepolia for: Yield disclosure submission Attestor staking and validation Automated yield authorization and enforcement Slashing mechanics for fraudulent disclosures Ensured non-custodial design where issuers never access investor principal Deployed and tested contracts on Mantle Sepolia testnet Attestor & Incentive Mechanisms Built an economic consensus model where attestors stake capital to verify disclosures Implemented reward and penalty logic to align incentives toward honest validation Integrated basic issuer reputation tracking tied to historical disclosure accuracy Frontend & User Experience Developed a production-grade Next.js 14 frontend with: Issuer portal for submitting yield disclosures Investor dashboard for viewing verified yields and distributions Attestor interface for reviewing and validating disclosures Integrated Web3 wallet connectivity using Wagmi, RainbowKit, and Viem Designed a professional, glass-morphism UI focused on clarity and transparency End-to-End Demo Readiness Connected frontend and smart contracts for a complete user flow Enabled real-time visibility into disclosure status, verification results, and yield distribution eligibility Deployed a live application accessible to judges and users Deliverables Completed Live MVP on Mantle Sepolia Deployed smart contracts with documented interfaces Fully functional Web3 frontend Public GitHub repository with clean project structure and setup instructions Outcome: By the end of the hackathon, YieldProof evolved from a concept into a working, composable DeFi protocol that proves the feasibility of trustless yield verification for RWAs and is ready for mainnet hardening and institutional integration.
Tech Stack
Fundraising Status
Funding & Support Required YieldProof has reached a fully functional MVP stage during the hackathon, validating both the technical feasibility and market relevance of trustless yield verification for RWAs. To transition from a hackathon prototype to a production-ready, institutional-grade protocol, additional funding and ecosystem support are required. Use of Funds Security Audits Conduct comprehensive smart contract audits and economic model reviews to harden slashing, staking, and verification mechanisms. Oracle & Proof Infrastructure Integrate robust oracle providers and verifiable computation frameworks for real-world revenue proofs. Mainnet Deployment Deploy and maintain the protocol on Mantle mainnet with production monitoring and fail-safes. Protocol Expansion Extend attestor reputation systems, dispute resolution mechanisms, and advanced analytics dashboards. Ecosystem & Institutional Integrations Build APIs and tooling for RWA issuers, DeFi protocols, and institutional partners. Why Funding Matters YieldProof addresses a foundational trust gap in the RWA ecosystem. Without verifiable yield, RWAs cannot safely scale into DeFi. Funding enables us to transform YieldProof from an MVP into a core infrastructure primitive for transparent, enforceable on-chain yield. We are seeking funding, grants, or incubation support to accelerate security hardening, mainnet launch, and ecosystem adoption.
