Swap lets you exchange one token for another from inside Peach. Behind the scenes, a swap is a regular on-chain trade: Peach quotes you a price, you sign a transaction, and the trade executes on a decentralized exchange.Documentation Index

Peach fetches a quote
Peach queries Relay Router for the best route across supported networks and DEXs.
You review the quote
The screen shows the expected output, the route, the price impact, the fees (Peach + network), and the slippage tolerance — before you sign.
Who does what
| Role | Who |
|---|---|
| Builds the user interface and transaction | Peach |
| Quotes price and route | Relay Router |
| Provides liquidity / fills the trade | DEXs and on-chain market makers |
| Settles on-chain | The destination network |
| Signs the transaction | You |
Relay is a cross-chain liquidity router. It can settle a swap on the same network the input token is on, or — if the better price is elsewhere — bridge through another network on the way. The route you see in the quote is the route that will be executed.
Fees
| Fee | Charged by | Notes |
|---|---|---|
| Peach swap fee — 0.1% | Peach | Applied to the input amount of every swap. |
| Network gas | The network | Required by every on-chain transaction. Peach may sponsor gas in some cases — when it does, you will see that called out in the quote. |
| DEX / LP fees | The DEX | Built into the price you receive (e.g., a 0.3% Uniswap pool fee shows up as worse output, not a separate line). |
| Bridge / solver fees | Relay | If the route crosses networks, the bridge cost is included in the quote. |
The 0.1% Peach fee is current at the time of writing and is subject to change. Any change will be reflected in the in-app quote, which is the source of truth at the time of your trade.
Slippage and price impact
Because swaps execute against on-chain liquidity, the price you actually get can move between the moment you accept a quote and the moment the trade settles.- Slippage tolerance is the maximum unfavorable move you are willing to accept before the trade reverts. Lower is safer; too low risks the trade failing during volatile moments.
- Price impact is how much your own trade moves the market price. Large trades against thin liquidity have higher price impact — the quote will warn you when this is significant.
What Peach does not do
- Peach does not run an order book.
- Peach does not make markets or hold inventory.
- Peach is not the counterparty to your trade.
- Peach does not custody the input or output tokens — they go directly between your wallet and the DEX.
