8inch

Problem Statement

A seamless intent-based exchange enabling direct asset swaps between Ethereum Virtual Machine (EVM) compatible networks and the Aptos blockchain. Powered by 1inch's Fusion+ technology, this cross-chain bridge eliminates the complexity of multi-step transactions, allowing users to trade tokens across different blockchain ecosystems with minimal friction.Key features include:One-click cross-chain swaps between EVM chains (Ethereum, BSC, Polygon, etc.) and AptosAbility to unify liquidity pools - aggregating assets from multiple networksLow latency transactions with optimized routing algorithmsSecure cross-chain validation through Fusion+'s advanced bridge infrastructureCompetitive rates with minimal slippage across supported networks

Solution

Smart Contract Infrastructure - Leverages 1inch's battle-tested Solidity smart contracts for EVM-side operations, paired with custom MOVE language smart contracts optimized for Aptos blockchain interactions Developer Framework - Built using industry-standard tooling including Foundry for smart contract development and testing, ethers.js for Ethereum ecosystem integration, and aptos.js for seamless Aptos blockchain connectivity Cross-Chain Communication - Fusion+ protocol handles secure message passing and state verification between heterogeneous blockchain environments
