FEAWS

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.
