Practical slippage starting points: ~0.2% for deep established pairs, 0.5–1% for volatile memecoins — too loose posts a bounty for bots, too tight reverts; tune just above the pair's real drift.

Slippage tolerance (your minOut) is a trade-off with two failure modes. Set it too LOOSE and you post a bounty: sandwich bots can legally take everything you tolerated. Set it too TIGHT and volatile markets move past your floor before inclusion — the transaction reverts, you pay gas, and nothing fills. The right number is the smallest one that usually fills for THAT pair's volatility and depth.

Starting points that work in practice: ~0.2% for established, deep pairs (ETH/USDC, WETH/major stables) — their pools are deep enough that honest drift rarely exceeds it. 0.5% for mid-liquidity tokens. For genuinely volatile or thin memecoins, 0.5–1% — accepted consciously, knowing that the tolerance is a real cost you may pay. These are starting points, not laws: your size relative to the pool moves the answer.

## When to deviate, and what not to do

Tighten below 0.2% when you are patient: a revert costs cents on an L2, so retrying with a tight floor is cheap insurance. Loosen — deliberately, one notch at a time — when repeated reverts show real volatility, or when your order is large relative to the pool (check the max-safe-trade figure in the X-Ray first; if your size needs 3% tolerance, the honest move is usually a smaller order, not a looser floor).

Never use "auto" or double-digit tolerance on a liquid pair — that is not a setting, it is a donation. And remember the backstop: on BlazePhoenix the contract re-derives its own floor (hard-clamped at 75%, per-leg) regardless of what you set — your slippage choice tunes everyday protection ABOVE a floor no one can remove.

**Verify it yourself:** quote the same pair twice a minute apart on /api/quote — the drift between them is the pair's real volatility, and your tolerance should sit just above it
