Meta DEX Aggregator — Multi-Source Quote Comparison with Safety Layer

Aggregator of aggregators. Queries 5 DEX aggregators in parallel, ranks by gas-adjusted net output, and runs safety checks before execution.

Safety Features

1. Price Impact — Fetches fair market price from DefiLlama coins API (+ DexScreener fallback), compares vs quote output. Thresholds: 3% warning, 5% high, 10% critical (blocks swap).
2. Gas-Adjusted Ranking — netOut = amountUsd - gasUsd. Best route ≠ most tokens.
3. MEV Protection Flags — CowSwap and 0x Gasless are flagged isMEVSafe. Recommends MEV-safe route when within 0.5% of best price.
4. Slippage Warnings — Sandwich risk >1%, stablecoin pairs >0.05%, too-low revert risk.
5. Outlier Detection — Quotes >5% worse than best are flagged as outliers.
