Cross-Chain Lending Borrowing for IP NFTs

Pitch: Canva
Accessing liquidity using intellectual property (IP) or NFTs has traditionally been:
Difficult – Most DeFi protocols only support fungible tokens like ETH or USDC.
Inefficient – NFTs and IP often sit idle, generating no value.
Risky – Liquidations are often abrupt and non-transparent.
Isolated – Lending opportunities are limited to single chains.
Centralized – Borrowing terms are fixed by protocol maintainers.
Pixcross is a cross-chain NFT lending protocol that uses MetaMask as the core wallet gateway and Chainlink CCIP for secure cross-chain interactions. It enables:
Simple UX – Borrow stablecoins instantly using your IP/NFTs with just MetaMask.
Safe Liquidations – 24-hour auction-based liquidation model that is fair and transparent.
Customizable Pools – Anyone can create pools with unique collateral rules, LTV, and rates.
Cross-chain Borrowing – Live on Ethereum, Base, Arbitrum, and Avalanche via Chainlink CCIP.
Permissionless Participation – No KYC or gatekeeping; just connect MetaMask and use.
IP creators monetize digital assets without selling them
Collectors use idle NFTs to borrow stablecoins
DeFi users earn passive yield via curated lending pools
Builders create specialized lending pools for IP verticals
Curators manage capital and earn performance-based fees
Here few challanges i ran into:
Building a unified lending experience across Ethereum Sepolia, Base, Arbitrum, and Avalanche introduced complexity in asset messaging, state syncing, and security.
Solution: Chainlink CCIP allowed us to relay ERC-20 tokens and messages securely between chains. We coordinated these flows with MetaMask to ensure users could interact across networks without friction, using the same wallet session.
Chainlink CCIP does not yet support ERC-721 bridging, but we needed NFTs to flow across chains for lending eligibility.
Solution: We implemented a custom burn-and-mint NFT bridge, coordinated with CCIP messages to maintain trustless, synced ownership. MetaMask provided a single wallet interface across chains, making it seamless for users to approve and view cross-chain NFT status.
Valuing IP or NFTs in real time is tricky due to lack of liquid markets and price feeds.
Solution: We used Chainlink’s flexible oracle design to set up custom price feeds, with plans to integrate Chainlink Functions and off-chain appraisal data. MetaMask's tight transaction flow allowed us to show users valuation and risk metrics before they borrowed.
We designed a time-locked, 24-hour auction mechanism for liquidating collateral — a major step beyond instant liquidations.
Solution: Chainlink CCIP helped us trigger liquidation events across chains, while MetaMask enabled users to monitor, bid, and approve all interactions within one interface — ensuring clarity, fairness, and control.
Cross-chain UX is often clunky. Users face unexpected network switches, gas costs, and transaction confusion.
Solution: We used MetaMask’s multi-network support and Snap ecosystem (WIP) to make cross-chain lending intuitive. Chainlink CCIP abstracted complex messaging, reducing latency and gas costs while MetaMask handled approvals smoothly.
During the hackathon, we designed and built the initial MVP of Pixcross, a cross-chain NFT lending protocol for IP-backed assets. Our key accomplishments include: Core Functionality, MetaMask Integration, Chainlink CCIP Integration, ERC-721 Cross-Chain Bridge, Frontend Application, Documentation & Demo Prep.
