Problem Statement

Global PayChain revolutionizes how international money transfers are done using blockchain cross-chain token transfer. Instead of dealing with the hassle of expensive and complicated international transfers, simply click once to set up a wallet, buy SOL, swap currencies, and complete transactions.

Solution

We built this using the Squid SDK Axelar protocol for general message passing, as well as Solidity gas optimization. We used Solana smart contract transactions, and the Metamask SDK and ethers.js to connect wallets. We used the T3 stack on Next.JS with Next Auth and decentralized storage to integrate our full stack application.
