DeFi.app aims to simplify DeFi trading while maintaining full self-custody of crypto assets. Through DeFi.app, users can buy tokens on any blockchain, perform "instant, one-click" cross-chain swaps, access decentralized derivatives markets and yield opportunities — all without gas fees or the need for bridges — Greer said. The platform uses "full-chain abstraction" to eliminate gas fees, employs passkeys and biometrics for security and requires no know-your-customer (KYC) checks.
