About

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 workflow - Reduced counterparty risk: No custody periods where funds could be lost or stolen - Cost optimization: Route transactions through whichever chain is cheaper at the moment - Payment apps that automatically find the best rates across both chains - DeFi protocols that can tap liquidity from both ecosystems seamlessly - Traders who want cross-chain arbitrage without centralized exchange friction The 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.

How it's made

- Both parties create escrows with same hash-lock on different chains - Fund escrows - One party reveals secret → both can claim tokens - If timeout → automatic refunds Infrastructure: - Runs in Oasis Protocol ROFL (Intel TDX TEE) - Uses 1inch Limit Order Protocol contracts - Supports multi-transaction funding on XRPL - Cloudflared tunnel for secure access
