How it works
Every corridor, say cNGN ↔ USDT, has its own request-for-quote. You name a size. Makers price that size, right now. You get one firm quote or a clear "nobody quoted", and the swap settles on-chain in one transaction.
Request for quote
A swap is not a browse of leftover prices. It is a request:
- You choose a pair and an amount, for example sell cNGN, receive USDT. You can name the sell size or the exact amount you want to receive.
- The app shows an indicative rate from published maker levels, then asks the makers online on that corridor to price the full size. They have about a second.
- You get one firm quote with a countdown, or
no_quote. The quote is bound to your wallet. Nobody else can take it. - You submit before it expires. The signed quote executes through the settlement contract, and the output lands in your wallet in the same transaction.
A quote covers the whole amount. There is no partial fill. If the makers together cannot do the full size, you get no_quote rather than a smaller trade. Try a smaller amount, or name your own price with a limit order and wait.
Quotes expire after about 60 seconds. A long-open tab does not keep asking makers. Request a new quote if the countdown runs out.
Limit orders: name your own price
Swap takes a firm quote now. A limit order flips that. You set the price, sign a gasless order, and wait. Your funds stay in your wallet. A maker fills it when your price is worth taking.
The order expires on its own, anywhere from 5 minutes to a year. Cancelling is a small on-chain transaction that permanently revokes the signature. See How to place a limit order.
What you pay
Swaps carry a small taker fee, set per chain on-chain and already baked into the quoted rate. The maker earns the spread they quoted. The protocol earns the taker fee. There are no other charges. See Fees for the per-chain rates and a worked example.
