Know what your trade will cost
Understand each part of a future quote so the headline price does not hide the result you may receive.
TL;DR
- The trading fee is 2% on the bonding curve and 1% after graduation.
- Price impact is movement caused by your trade; slippage is extra movement you permit before failure.
- Minimum received, any anti-MEV surcharge and Base Chain network gas belong in the same decision.
Trading is currently paused
Buying and selling are paused across Orbit Moon for the first four days so creators can prepare their projects and communities. On Day 4, the platform-wide pause ends; each creator chooses when their coin opens. Learn the quote now without implying a trade can execute.
The headline price describes the market before your action. The quote explains what may happen when your amount, the route and the transaction boundaries meet that market.
Give every quote item one job
| Item | What it tells you |
|---|---|
| Route | Bonding curve before graduation or Uniswap V4 after it |
| Trading fee | 2% on the curve or 1% after graduation |
| Price impact | Expected market movement caused by this order |
| Slippage tolerance | Further movement allowed while the transaction settles |
| Minimum received | Least output the transaction may accept |
| Network cost | Estimated Base Chain gas when it applies to the selected wallet path |
Network gas is separate from Orbit’s trading fee. A wallet can therefore need enough ETH for both the buy amount and the Base Chain transaction cost.
Keep impact and slippage separate
High impact can exist even when nobody else trades before settlement because your own order moves the market. Raising slippage does not improve that quote; it permits a worse result before the transaction refuses to complete.
The panel defaults to Auto and also offers 0.5%, 1%, 3% and a custom value. A low tolerance can fail as price moves. A high one can settle beyond a boundary you would otherwise reject.
Impact-based surcharge
Moving the curve further costs more
Understand the large-curve-trade surcharge
On the bonding curve, additional anti-MEV fee applies only above 10% price impact and grows with impact on buys and sells. It responds to the trade’s impact, not the trader’s identity. Splitting an order may change impact but creates multiple trades and fees.
Understand Orbit’s contract protections explains why this surcharge is a speed bump rather than a guarantee against bots or poor execution.
Good to know
A successful transaction can still be a poor trade. If impact or minimum received crosses your boundary, reduce the future amount or do not proceed.
Common questions
Does higher slippage make a transaction faster?
No. It changes the worst movement the transaction may accept; it does not improve the route, quote or network confirmation time.
Does the anti-MEV surcharge prove a trade is protected from bots?
No. It responds to impact and does not identify trader intent. Same-block provenance and other contract checks narrow specific paths without guaranteeing protection from bots.
Where can I see these checks in order?
Make your first trade owns the wallet, amount, quote and confirmation sequence. It is preparation only while trading is paused.
