Cross chain Swaps and Beyond with 1inch
summary
1inch reports 3M users, $55B available liquidity and 38% aggregator market share, and demonstrates a working cross‑chain swap from Ethereum to Base using Fusion Plus implemented with HTLCs. Fusion shows a 3,700 WETH -> USDT auction filled by ~17 resolvers at slightly above market rate. APIs and SDKs (TypeScript, Go) power intent‑based, gasless Dutch auctions and a Vercel proxy demo for safe frontend keys. Bounties target non‑EVM HTLC implementations and limit order extensions.
