Overview
Sharky.fi is peer-to-peer NFT lending on Solana: holders unlock instant liquidity by using their NFTs as collateral without selling, and lenders put idle SOL to work funding those loans. We contributed to the on-chain program and the trading-grade dApp that together make borrowing and lending against NFTs fast, cheap, and trust-minimized across hundreds of collections.
The challenge
NFT-backed lending is hard to make safe and instant: collateral is illiquid and volatile, loans must be escrowed and liquidated trustlessly, and the whole flow has to feel instant and near-free to compete on Solana. It needed an order-book of loan offers per collection, sound liquidation and default handling, and an interface that made a complex financial primitive feel like one click.
Our solution
We helped build Solana on-chain programs (Rust / Anchor) for escrowed, collection-scoped loan offers with defined durations, interest, and trustless liquidation on default, paired with a fast Next.js dApp. The app surfaces live loan offers, floor prices, and portfolio positions, integrates Solana wallets, and settles borrow, repay, and lend actions in seconds at minimal cost — plus SHARX holder rewards and analytics on top.
