TulipSwap

[UNFINISHED - UNRELATED VIDEO] This project is an experimental cross-chain swap built using the 1inch Fusion+ protocol and the Aptos blockchain. The core idea was to enable seamless swaps between users on different chains, particularly allowing non-EVM wallets (like Aptos) to interact with Fusion+ swaps on EVM chains such as Ethereum, Polygon, and others.

[UNFINISHED - UNRELATED VIDEO] • Next.js – Used for both the frontend and backend, enabling a fast developer workflow and server-side logic for wallet management and API integration. • 1inch Fusion+ – The core swapping protocol, providing gasless and MEV-resistant swaps using Dutch auctions. • @1inch/cross-chain-sdk – Used to construct and sign Fusion+ orders off-chain. We extended its capabilities to support non-EVM initiators by simulating EIP-712-compatible signatures with Aptos accounts. • @aptos-labs/ts-sdk – Used to manage Aptos wallets, deploy Move modules, interact with the chain, and handle transaction signing.
