Prefer intent-based routing for trades > $10,000.
For large orders splitting across time:
chunkSize = totalAmount / numChunks
interval = totalDuration / numChunks
| Trade Size | Recommended Slippage | Method |
|---|---|---|
| < $1K | 0.5% | Public or private |
| $1K–$10K | 0.5–1% | Private mempool |
| $10K–$100K | TWAP 5–10 chunks | Intent or Flashbots |
| > $100K | TWAP + intent protocol | CoW/UniswapX |
