AbiPago

AbiPago solves a real world crypto payments problem: merchants and users rarely share the same chain or token, and “how to get paid” is often centralized or manual. AbiPago turns a simple NFC/QR invoice into an intent like payment flow backed by portable onchain configuration. A merchant uses an ENS name (e.g., cafeteria.eth) and stores a payment profile in ENS text records: desired token, settlement chain, receiver address, and optional settings (expiry, slippage). A payer scans a QR or taps an NFC tag, AbiPago resolves ENS and automatically builds the best route from the payer’s current assets to the merchant’s requested settlement. AbiPago executes cross-chain routing using LI.FI Composer (swap, bridge, and optionally contract call). On the destination chain, a PayRouter receives funds, optionally performs a final Uniswap v4 swap (Universal Router) if needed, and pays the merchant, emitting an onchain receipt event

AbiPago is a React Native mobile payments app that turns a simple NFC tap or QR scan into an end-to-end onchain payment. Merchants publish a “payment profile” on ENS using text records (pay.chainId, pay.token, pay.receiver, etc.), so the app can resolve human readable names (no 0x) and auto configure settlement without any centralized settings. When a user pays, AbiPago connects via WalletConnect and uses LI.FI Composer routes to swap/bridge from the user’s current chain/token into the merchant’s desired chain/token. On the destination chain we call our Solidity PayRouter contract to finalize settlement; if the incoming asset doesn’t match the merchant’s requested token, PayRouter performs a final swap using Uniswap v4 (via Universal Router) before transferring funds and emitting an onchain receipt event. The “hacky” bit: ENS acts as a portable payments configuration layer, and LI.FI + Uniswap v4 make the entire cross-chain swap-> pay flow feel like a single tap.
