Xeno
Xeno
Xeno is a payment infrastructure that turns Web3 wallets into contactless payment instruments, settling stablecoin payments directly on-chain via NFC on existing terminals (PAX, Verifone, Ingenico) and Android/iOS devices. It positions itself as a self-custodial card scheme as an alternative to traditional networks: keys stay with the user, transactions settle in about 2 seconds with no banks and no chargebacks. It settles on Base, Solana and Ethereum with USDC and PAX support. The team comes from Barclays, TUI and PassEntry.
