4	`onchainos swap quote --from ... --to ... --readable-amount ... --chain ...`	Get swap quote (read-only price estimate). No `--slippage` param.
5	`onchainos swap execute --from ... --to ... --readable-amount ... --chain ... --wallet ... [--slippage <pct>] [--gas-level <level>] [--mev-protection]`	One-shot swap: quote → approve (if needed) → swap → sign & broadcast → txHash.
6	`onchainos swap swap --from ... --to ... --readable-amount ... --chain ... --wallet ... [--slippage <pct>]`	Calldata only: returns unsigned tx data. Does NOT sign or broadcast.

#	Preset	Scenario	Slippage	Gas
1	Meme/Low-cap	Meme coins, new tokens, low liquidity	autoSlippage (ref 5%-20%)	`fast`
