Description
MERIDIAN is a Mantle-native protocol for tokenizing real-world assets with privacy-preserving compliance. We built a complete end-to-end system: ERC-4626 compliant vaults for RWA tokenization, a zero-knowledge KYC verification system, a composable yield aggregator, and a full-featured React frontend.
The protocol solves a critical problem: institutional capital can't flow into DeFi because there's no compliant infrastructure for real-world assets. MERIDIAN changes that by combining three innovations: (1) Standard ERC-4626 vaults that work with any DeFi protocol, (2) ZK-proofs for KYC that preserve privacy while proving compliance, and (3) a yield aggregator that lets users stack strategies across multiple asset classes.
Everything is deployed and functional on Mantle Testnet. Users can connect their wallet, complete KYC verification, deposit into vaults representing US Treasuries, real estate, trade finance, or carbon credits, and earn yield while maintaining compliance. The smart contracts use battle-tested OpenZeppelin primitives and follow industry standards.
We chose Mantle because RWA transactions need to be economically viable frequent deposits, rebalancing, and compliance checks can't cost $50 in gas. Mantle's sub-cent transactions make institutional RWA flows possible.Progress During Hackathon
