I'd like to create a full list of operating open-source, trustless crosschain exchanges.
At the moment I was able to find the following ones:
- BlockDx (actively traded coins: BLOCK, LTC, DGB, DASH, SYS)
- Swap.online (actively traded coins: BTC, LTC, ETH, SWAP)
- AtomicWallet1 (actively traded coins: BTC, LTC, QTUM)
- Bisq (actively traded coins: Monero, BTC)
- SparkSwap (actively traded coins: BTC, LTC)
- BarterDex2
For Block DX you can see the full list of tradable assets here:
https://docs.blocknet.co/blockdx/listings/#listed-digital-assets- AtomicWallet is a hybrid exchange. A majority of the pairs actually use a centralized service for the exchange. I believe it's just BTC and LTC that use atomic swaps. This also uses centralized wallets for checks which is an invitation for an exploit. I don't know the details about their order book and order matching, but I'd wager those aren't P2P/trustless.
- Bisq is not trustless, the users need to trust the arbitors that the funds are locked in the multisig with.
