SwappaTEE

Problem Statement

SwappaTEE enables trustless token swaps between XRPL and Ethereum chains without intermediaries. It is powered by 1Inch's Fusion+ protocol and a TEE implementation of the escrow contracts on the XRPL side.Instead of using centralized exchanges or risky bridge protocols, users get direct wallet-to-wallet swaps between XRPL and Ethereum. The TEE ensures escrow contracts execute correctly without requiring trust in any intermediary.Better liquidity access: XRPL's fast payments + Ethereum's deep DeFi markets in one workflowReduced counterparty risk: No custody periods where funds could be lost or stolenCost optimization: Route transactions through whichever chain is cheaper at the momentPayment apps that automatically find the best rates across both chainsDeFi protocols that can tap liquidity from both ecosystems seamlesslyTraders who want cross-chain arbitrage without centralized exchange frictionThe TEE approach is more secure than typical bridges (which have lost billions to hacks) while being more decentralized than custodial solutions. 1Inch's Fusion+ integration adds professional-grade order execution.
