The swap, step by step
Swapcoin is a non-custodial swap aggregator. It never holds your money: you keep your wallet, your keys and your coins at every step. Swapcoin's job is to find the best route for your swap and hand you a ready-to-sign transaction.
- Pick a pair. Choose the asset you want to spend and the one you want to receive, then pick the network you want to send from — or let Swapcoin suggest the optimum chain.
- Connect your wallet. No registration, no KYC, no forms. Just sign in with the wallet you already use.
- Compare live quotes. Swapcoin aggregates prices across 27 DEXes and 30 bridges on 17 networks, so you always see the best available rate instead of a single destination exchange's price.
- Review the route. See exactly which providers are involved, what the provider fee is, what the network gas is, and how much you receive. No hidden markups.
- Sign the transaction. You approve and sign in your wallet. Funds move directly from your address to the destination address — your assets are never deposited with us.
- Track settlement. Follow the swap live until it is confirmed on the destination chain. Transactions settle automatically.
Where the best rate comes from
A single exchange can only quote you its own liquidity. Swapcoin doesn't work that way. When you start a swap, it queries 27 DEX aggregators and 30 bridges at once and splits or routes the order through the combination that gives you the most out.
That means one thing in practice: the price you see is a market-wide price, not a walled-garden price. And because the entire flow stays non-custodial, the best rate never comes with a withdrawal fee or a freezing risk attached.
Same-chain and cross-chain swaps
Swapcoin handles both types of swaps in the same interface:
- Same-chain swaps move from one token to another on the same network — for example, from ETH to USDT on Ethereum. These settle in seconds and cost only the native chain gas.
- Cross-chain swaps move value from one network to another — for example, from USDC on Solana to USDT on Arbitrum. Bridges and liquidity between the two chains handle the leg, and you receive the asset on the destination network.
If the cheapest route involves moving through several chains, Swapcoin chains the legs automatically. You still sign one transaction — the routing happens for you.
Fees and gas, explained
Two costs appear on the confirmation screen:
- Provider fee — a small service fee routed through the liquidity providers that execute your swap. It is shown in the quote before you sign.
- Network gas — the fee paid to the blockchain itself for processing the transaction. It varies with network load and is set by the chain, not by Swapcoin.
The effective price is always displayed in the review step. You approve the final amount you receive — if the route changes and the rate moves while your transaction waits, you can re-quote before signing.
Non-custodial by design
Swapcoin never has your coins — not before the swap, not during it, not after it. Your wallet signs the transactions and your assets move directly between your addresses. This design removes the largest known failure point in crypto: the exchange that holds user funds and becomes a target.
If an exchange is hacked but it never custodyed your assets, there is nothing of yours to lose. That principle is the whole architecture of swapcoin.exchange.
