SuperNova

Our project extends the 1inch Fusion+ protocol to enable trust-minimized, atomic token swaps between Ethereum (EVM) and Move-based chains like Sui and Aptos. It bridges the interoperability gap between fundamentally different virtual machines — the account-based EVM and the resource-oriented MoveVM — while preserving hashlock and timelock guarantees that are central to Fusion+’s secure swap mechanism.

Supernova is a modular extension to 1inch Fusion+, designed to enable atomic swaps between Ethereum (EVM) and Sui/Aptos (MoveVM) — unlocking secure, cross-VM interoperability. Built using the Zap Protocol for off-chain coordination and messaging, Supernova maintains full support for hashlock and timelock mechanisms for atomicity.

🧱 Architecture & Technologies 🛠 Smart Contracts EVM Chains (Ethereum Sepolia, Avalanche Fuji, Arbitrum Sepolia)

Forked and deployed a lightweight version of 1inch’s LimitOrderProtocol, EscrowFactory, and a custom Resolver.

MoveVM Chains (Sui, Aptos)

Custom-written Move smart contracts for token minting, escrow creation, and resolver logic.

Modules mimic the EVM escrow behavior, including hashlock-timelock logic.

🧪 Command-Line Interface Built a Node.js CLI tool for:

Creating off-chain signed orders (EIP-712 for EVM)

Registering resolver addresses and secrets

Executing swaps across chains

Minting mock tokens on testnets

🧠 Cross-Chain Coordination Designed a MultiVMResolverExtension, which:

Extends the post-interaction hook of 1inch Fusion+ orders

Embeds metadata for non-EVM execution

Keeps Fusion+ architecture modular and backwards-compatible

🪙 Token Mocking Deployed mock USDC contracts across all testnets.

CLI allows users to freely mint tokens to simulate liquidity and test swap flows.
