FusionX-Eth-Cos

Problem Statement

We’re building a bidirectional swap bridge between Ethereum and Cosmos, powered by 1inch Fusion+ and a CosmWasm-based HTLC (Hash Time Locked Contract). The project enables fully onchain execution of token transfers, preserving hashlock and timelock mechanics on both sides. Users will be able to create swap orders from Ethereum and have them settled on Cosmos—and vice versa. This expands the reach of 1inch Fusion+ to Cosmos, making cross-chain liquidity truly interoperable between an EVM chain and a Cosmos chain.

Solution

The project uses various wallets to connect Ethereum and Cosmos network .Cosmos-side HTLC contract would be written by CosmWasm.Deploy to a Cosmos chain like Juno,Neutron or Osmosis Test Net.Use React/Next.js front-end with wallet connection for Ethereum and Cosmos.Use Viem + Wagmi + RainbowKit for Ethereum.Use CosmJS for Cosmos interaction
