Problem Pixcross Solves

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.

What Pixcross Enables

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.

Use Cases

• 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

Challanges

Here few challanges i ran into:

1. Cross-Chain Interoperability

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.

2. Bridging NFTs (ERC-721 Not Yet Supported by CCIP)

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.

3. Oracle-Based NFT Valuation

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.

4. Secure, Fair Liquidations

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.

5. UX and Gas Efficiency in Multi-Chain UX

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.
