What it does
BasicSwap combines locally controlled coin wallets with a distributed offer book. Its atomic swaps exchange supported native cryptocurrencies across their own blockchains. The software has no registration or protocol trading fee, although blockchain charges apply. Desktop use involves installing and maintaining the client and its coin software.
Running the desktop client
BasicSwap Desktop supports Linux and Mac; Windows setup uses WSL, the Windows environment for running Linux software. Each installation builds the client and coin components from source. The supported-pair table matters: a listed coin cannot necessarily trade with every other listed coin.
After installation, Wallets shows synchronization progress. Manage opens the selected coin's deposit address and withdrawal controls. BasicSwap's terms require users to be of legal age and able to enter agreements locally; users remain responsible for whether their activity is permitted where they live.
Set the offer you want to publish
In New Offer, choose the coins and amounts under You Send and You Get. Fetch Rate supplies an editable starting price. Lock Rate keeps the rate steady when the amount changes. Amount Variable permits smaller bids, while Rate Variable allows bids at a different price.
The next screen controls offer expiry and the contract timeout. Choose Accept All for automatic matching or Accept Known to limit that behavior to previous counterparties. Otherwise, review incoming bids under Bids before accepting one. Review the offer and confirm publication; the bid's Events area records its progress.
Completed swaps do not automatically remove the offer. It can remain available until expiry, which matters when automatic acceptance is enabled.
Charges and responsibilities
The MIT-licensed software is free to use, with no maker or taker protocol charge. Each swap still incurs the underlying chains' transaction fees. BasicSwap requires the node to remain online throughout settlement, which can take multiple confirmations on both chains.
Keep the wallet seed and node data backed up. BasicSwap warns that software bugs, lost keys and long disconnections can leave funds stuck or lost. The agreed coin ratio also does not fix the assets' value in ordinary currency.
