Every DeFi intent today dies after execution — you swap, it's done; you deposit, it's forgotten. Sigil changes that. Type your intent in plain English — "Put 2 ETH into yield, exit if ETH drops below $3,500" — and an AI agent decomposes it into on-chain actions. Immediate steps execute right away, while persistent on-chain watchers keep monitoring prices, governance, and risk. When conditions change, Sigil automatically creates and executes a new intent — no human needed. It's the difference between a one-time instruction and a standing guardian for your position. Built on Arbitrum, designed to extend across Orbit chains and Robinhood Chain.
Sigil is a Persistent Intent Engine on Arbitrum. Every existing intent protocol CoW Protocol, UniswapX, Anoma follows the same lifecycle: an intent is expressed, a solver executes it, and the intent dies. But real financial goals aren't one-shot transactions. Sigil keeps intents alive after execution through on-chain watchers that continuously monitor prices, governance proposals, and risk conditions. When those conditions change, an AI agent decomposes a new intent and the protocol executes it automatically closing the loop without human intervention. Users simply describe what they want in plain English (e.g., "put 2 ETH into yield, exit if price drops below $3,500"), and Sigil handles decomposition, execution, monitoring, and reaction end-to-end.
