BEST_EXECUTION_ROUTE @ 1.0.0

Best execution route: every chain and venue compared after gas, impact and fees

Where should this trade actually execute? Arbiter quotes your swap on every venue of its book (Uniswap V3 every fee tier, Uniswap V2, PancakeSwap V2) on 1-3 EVM chains you name, from on-chain reads two independent RPC operators agreed on, and compares every route after pool fee, price impact, any disclosed integrator fee and gas priced in the output token: net output, shortfall versus the best, and why each route lost - including when the pool that quotes the most is not the best after gas. Returns the unsigned, ready-to-sign transactions of the best route your wallet can fund (exact approval, hard minimum output, on-chain deadline), simulated from your wallet. You sign; Arbiter never signs, submits or holds funds. Example request: {"chainIds":[8453,42161],"tokenIn":"USDC","tokenOut":"WETH","amountIn":"40000","taker":"0xYourWallet"}. Declared completion: p95 3 s, max 15 s.
