0xSwap

0xSwap is a next-generation cross-chain token swap protocol powered by collectible NFTs (SwapScrolls). It delivers a seamless, automated, and gamified experience for swapping digital assets between major blockchains—no bridges, no headaches, just pure DeFi magic.

What exactly is 0xSwap? 0xSwap introduces a new paradigm for cross-chain swaps:

Mint: Users create (“mint”) unique SwapScroll NFTs that encode their intent to swap tokens across chains (e.g., 10 MATIC on Polygon → SUI on Sui).

Gamified UX: Each swap is visually represented and tracked by its SwapScroll NFT, complete with vibrant previews and even rarity traits—blending DeFi utility with NFT collectibility.

Burn to Swap: To execute the swap, users “burn” their NFT, triggering a fully automated, non-custodial cross-chain swap using advanced bridges (e.g., LayerZero, 1inch Fusion+).

Rewards: Successful swappers can earn special reward NFTs (“Cross-chain Wizard”) and climb leaderboards, adding a fun, sticky dynamic to cross-chain DeFi.

Why is 0xSwap different? Truly Seamless Cross-Chain UX: No more multi-step bridging or wrapping. Just mint, burn, and receive on your target chain—all via a beautiful, easy UI.

NFT-Powered: Every swap is an NFT that can be viewed, tracked, or even gifted. This means swaps become assets in themselves, with social and collectible layers.

Decentralized & Secure: All swaps are executed using audited, proven DeFi protocols under the hood. User funds remain self-custodied until the swap happens.

Maximum Transparency: Each SwapScroll NFT contains the full, immutable record of the swap—source, destination, amounts, and status—making tracing and proving cross-chain activity simple.

Fun & Attractive: With animated burn/swapping steps, animated dashboards, user activity feeds, rarity badges, and leaderboard potential, 0xSwap brings a magical, playful feeling to serious DeFi infrastructure.

Who or what is it for? Every DeFi user frustrated by bridges, DEX limitations, or unsafe “multi-hop” swaps.

NFT degens who love on-chain collections and transparent, ownable records.

Projects/communities: 0xSwap’s API and NFT model enables “swaps as quests,” loyalty distributions, and composable DeFi campaigns.

Web3 builders and DAOs: Add branded SwapScroll flows to your dApps with minimal effort.

Any chain. Any time. Zero friction.

How does it work (simple flow)? User logs in with a wallet on their preferred chain.

Mints a SwapScroll by specifying source chain, dest chain, tokens, and amount.

Sees a live animated NFT preview of the swap.

Burns the NFT to initiate the swap. The protocol handles bridging, routing, and fulfillment—all on-chain, trustless, and composable.

Receives tokens on the target chain + potential rare NFT reward.

Tracks progress via futuristic dashboard and activity feed.

Why does it matter? 0xSwap is the playful “magic scroll” bridge for Web3—making cross-chain swaps as easy as buying an NFT. It transforms dry DeFi transactions into social, collectible experiences, while giving ordinary users the most powerful tool for moving value between chains, safely and with style.

No more confusion. No more lost funds. No more boring bridges. Just swap, burn, collect, and repeat. That’s 0xSwap.

0xSwap is built to deliver a seamless, secure, and engaging cross-chain token swapping experience powered by innovative NFT mechanics.

Technologies & Architecture:

Frontend: Developed with React and TypeScript for a fast, modular, and responsive user interface. Custom SVG animations power the magical minting, burn, and bridging visuals, creating an immersive user experience without heavy animation libraries.

Blockchain Interaction: Utilizes ethers.js alongside wagmi and RainbowKit for smooth multi-chain wallet connections and interactions.

Smart Contracts: Our custom ERC-721 based SwapScroll NFTs encode swap instructions and status on-chain. Burning the NFT triggers the swap process.

Cross-chain Communication: Integration of LayerZero and 1inch Fusion+ APIs facilitates reliable, atomic cross-chain swaps with best routing, mocked for hackathon demo.

Backend Orchestration: Node.js services listen to burn events, execute swap logic, and mint reward NFTs on the destination chain, bridging on-chain logic with smooth off-chain coordination.

Meta-transactions: Implemented meta-transaction architecture enables gasless swaps on destination chains, enhancing UX for users without native balances.

UI Features: Real-time progress tracking, detailed NFT metadata renders, leaderboard and activity feeds, and copyable wallet addresses complete the user journey.

Testing & Deployment: Hardhat for contracts, Vercel for frontend deployment, and GitHub Actions for CI/CD ensure robustness and reliability.

Noteworthy Innovations:

Encoding swap data within NFT metadata combines DeFi utility with NFT collectibility.

Pure SVG & CSS animations deliver high-performance, cross-device visual flair.

The meta-transaction design significantly reduces user friction for cross-chain swaps.

Event-driven backend orchestration mimics real-world LayerZero relay functionality safely in test environments.

0xSwap turns complex cross-chain operations into a transparent, game-like, and delightful experience while maintaining decentralization and security at its core.
