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.

The flow

1

You enter the trade

Pick the token you want to spend, the token you want to receive, and the amount.
2

Peach fetches a quote

Peach queries Relay Router for the best route across supported networks and DEXs.
3

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.
4

You sign once

Your signature authorizes the on-chain transaction(s) that complete the swap.
5

The DEX settles the trade

Settlement happens on-chain at the venue Relay routed through. Peach is not on the other side of the trade.

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

FeeCharged byNotes
Peach swap fee — 0.1%PeachApplied to the input amount of every swap.
Network gasThe networkRequired 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 feesThe DEXBuilt into the price you receive (e.g., a 0.3% Uniswap pool fee shows up as worse output, not a separate line).
Bridge / solver feesRelayIf 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.
For unfamiliar or thinly-traded tokens, double-check the quote and the route before signing. A reverted swap costs gas; a swap with bad price impact costs the trade.

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.
