About
### **1inch Limit Order Protocol Extension: Yield-Gated TWAP** FEAWS implements **advanced strategies and hooks** for the 1inch Limit Order Protocol, specifically **yield-gated TWAP swaps** that combine: - **Time-weighted average price (TWAP)** execution - **Yield-aware predicates** (only execute when destination asset yield ≥ threshold) - **Custom order hooks** via 1inch LoP predicates - **Advanced order types** beyond basic limit orders ## 1. Vision & Value Proposition FEAWS (Flexible Execution Automated Yield Swaps) allows treasuries and advanced traders to ladder into or out of positions **only when the real-time yield of the destination asset meets a configurable threshold**. It unites the capital-efficiency of TWAP/DCA with capital-productivity awareness (staking/lending yield), delivering smarter order execution on Ethereum & L2s. Key benefits: * **Lower slippage & better prices** – tranches smooth market impact. * **Yield-aware deployment** – capital moves only when it earns the desired return. * **100 % on-chain & trustless** – leverages 1inch Limit Order Protocol (LoP) predicates. * **Reusable building block** for treasury automation, robo-advisors, and yield strategies. --- ## 2. Problem Statement Treasury desks often dollar-cost average into yield-bearing assets (e.g. stETH, aUSDC) but: 1. Bulk swaps create slippage. 2. Static DCA ignores whether the yield is attractive. 3. Manual monitoring is error-prone and lacks execution discipline. ---
