The amount you spend is more than the bot’s fee. Account for MON gas, the platform’s charge, pool or route fees, token taxes and the effect of your order on the price.

| Cost | Where to check |
|---|---|
| Network gas | Wallet transaction estimate in MON. |
| Platform charge | Current bot schedule and your account tier. |
| Pool / route fee | Executable quote and route details. |
| Token tax | Contract behavior and token-specific buy/sell estimate. |
| Price impact | Quote for your actual order size. |
| Bridge or withdrawal charge | Provider quote, separate from the swap. |
Why the gas limit matters on Monad
The documented charge is gas limit multiplied by effective gas price. The effective price includes a base fee and any priority component. Do not assume unused computation will receive the same treatment as on another EVM network.
Illustration: 200,000 gas at 100 MON-gwei per gas is 0.02 MON, before any additional priority component. This is arithmetic under stated assumptions, not a live fee quote. The base fee and transaction estimate can change. Avoid increasing the gas limit dramatically just because a transaction failed.

Platform percentages are a separate layer
Maestro’s documentation states a 1% fee on successful buys and sells and a minimum accumulated fee extraction of 1 MON on Monad. This does not mean every trade costs exactly 1 MON. MEVX’s fee depends on account rank. A current Monad-specific GMGN fee has not been reverified for this release.
Check both entry and exit costs. A fee rebate is generally a fraction of the platform fee, not a percentage of the entire trade amount. Do not subtract maximum advertised cashback unless your eligibility and calculation base are confirmed.

Slippage and price impact are different
Price impact describes what your order does to the available market. Slippage tolerance is your permitted deviation from the displayed quote. Raising tolerance can allow a worse fill; it does not create liquidity. Check minimum received, and cancel the plan when the quote no longer fits your intended trade.
Priority does not guarantee success
A larger priority fee cannot fix an invalid transaction, a restricted token or an unavailable route. Fast block production also does not guarantee that the bot’s quote is fresh. Inspect the receipt and failure reason before retrying.
Execution checklist
- Quote the exact amount you intend to trade.
- Inspect minimum received and every disclosed fee.
- Leave MON for further transactions and pending platform charges.
- Check the signed network and gas limit.
- After submission, inspect the hash before repeating the order.

Frequently asked questions
Does low gas mean a cheap trade?
Not necessarily. A thin pool, token tax or platform fee can dominate the network charge.
Does higher slippage improve execution?
It permits a wider deterioration from the quote. It is not a promise of a better or faster fill.
