This dApp bridges EVM‐based DeFi with Stellar’s ultra‐fast, low‐fee rails to deliver seamless cross-chain swaps and instant global remittance. Users connect their wallet to view an on-chain portfolio—real-time ERC-20 balances, USD valuations, PnL/ROI breakdown and detailed token metadata via 1inch’s Balance, Portfolio, Token and Price APIs. They can search any token across networks using 1inch’s Token Search API. On the Swap page, selecting “From” & “To” assets triggers 1inch’s Classic Swap + Gas Price APIs to quote best rates, display exchange rate, estimated received amount, and gas cost, then generate the unsigned swap transaction payload. Once reviewed, a separate “Swap on Stellar” button mints a pegged custom asset (named after the destination token) on the Stellar testnet—automatically setting up trustlines and issuing the bridged amount via our Stellar Bridge service—and delivers funds instantly to a recipient’s Stellar address, showcasing a full “Swap → Bridge → Remit” workflow that leverages both 1inch’s DEX aggregation and Stellar’s programmable digital assets.
