Sabre

Sabre (Stable Arbitrage Bridge) is a user-friendly DeFi app that enables seamless, bidirectional stablecoin swaps between Ethereum and Sui blockchains. Powered by 1Inch's Fusion+ protocol, it features an arbitrage scanner to spot price differences in stablecoins like USDC across DEXes (Uniswap V3 on Ethereum and Cetus on Sui), allowing one-click trades for quick profits. Plus, an automation option. If the user likes a particular swap, a profit goal can be set for recurrent swapping every 5 minutes if conditions are met. With built-in safeguards like Chainlink peg protection and automated agents for recurring trades, it's designed for traders and DeFi enthusiasts seeking efficient, secure multichain opportunities—all via a simple dashboard with wallet connections (MetaMask and Sui Wallet).

Sabre, a DeFi extension for 1Inch Fusion+, was built using Replit’s Node.js/React environment and Claude AI for non-developer-friendly coding. Designed for bidirectional Ethereum (Sepolia) to Sui (Devnet) stablecoin swaps, it integrates Uniswap V3 and Cetus DEXes for arbitrage detection (>0.5% spreads), and limit order bundling, with an automated agent for recurring trades. MetaMask and Sui Wallet connections enable one-click execution via a React dashboard. Challenges like Celo’s liquidity issues prompted a pivot to Ethereum, with Claude fixing bugs (e.g., signer errors) and Replit’s Ghostwriter refining syntax.
