A cross-chain DEX
for atomic swaps,
without a middleman.

Swap Bitcoin, Monero, and 10 more coins peer-to-peer and on-chain. BasicSwap is the DEX where you meet other traders to settle atomic swaps directly. Trustless by cryptographic guarantee, not by promise.

Private. Cross-chain. Decentralized. Non-custodial.

Atomic swaps made easy.

Crypto removed intermediaries from sending money. Trading is the last place they still stand between you and the other party.

Atomic swaps solved this in theory, but they're complex to use on their own.

BasicSwap makes them usable, with a distributed order book and an open protocol where traders meet directly across chains, with no custodian, no account, and no one taking a cut. Cross-chain trading, finally ordinary.

from install to settled

How a swap works.

  1. 01

    Install the client

    Desktop builds the full protocol on your own machine, while Mobile rides inside wallets that have already integrated it. Neither asks for a signup or a form.

  2. 02

    Fund your own wallets

    BasicSwap generates addresses inside coin wallets that stay under your control, and funds go straight to those. No third party holds a deposit at any point.

  3. 03

    Post or take an offer

    The order book travels between peers over encrypted messaging, so a trader can post a price or take one that is already sitting there.

  4. 04

    The chains settle it

    Both sides lock, then release together. If one side walks away, the timelocks return the coins to their owners without anyone stepping in.

what makes basicswap different

What you get back.

  • Fully non-custodial

    You stay in control of your keys at every step of the swap. They never leave your local device. No bridge, no third-party custodian, no temporary loss of custody.

  • On-chain settlement

    Each swap is executed and settled by the underlying blockchains themselves. No off-chain promises, no liquidity pool risk, no intermediary chain or token.

  • Zero protocol fees

    The BasicSwap protocol takes no cut. You pay only the on-chain network cost of each transaction.

  • No account

    Launch the client, set up your wallet, and you're trading. No signup, no forms, no delays. Nothing personal is stored, so no breach can ever expose you.

  • Private by design

    Two layers of privacy. With no central operator, no one logs your trades. Orders move through encrypted peer-to-peer messaging, optionally over Tor. On-chain, adaptor signatures make every swap indistinguishable from a regular transaction.

  • Distributed order book

    The order book is built and maintained automatically by the network's nodes. No central matcher to throttle, censor, or prioritize some offers over others. No bot can front-run your trades.

under the hood

Three primitives that make it possible.

  • otves

    Adaptor signatures

    A single cryptographic operation binds both sides of a cross-chain swap. More private and efficient than regular atomic swaps, and compatible with scriptless chains like Monero.

  • smsg

    Secure messaging

    Encrypted peer-to-peer messaging carries the order book and the cryptographic exchange between matched traders. No central relayer, no operator in between.

  • lite

    Light nodes enabled

    Optionally, thin clients can read chain state from public Electrum nodes. No daemon to run, no full sync required. Bridges atomic swap security with everyday usability.
