First Lightning Network Exchange live on testnet : CryptoCurrency

Hi r/CryptoCurrency!

We just launched sparkswap (, the first cryptocurrency exchange built on the Lightning Network. It’s now live on testnet trading BTC/LTC (blog post here:

We use cross-chain atomic swaps over the Lightning Network, which means you never have to deposit your currency with an exchange or trusted third party, the swap is trustless, and trades settle nearly instantly (~1 second).

We’re looking for feedback on the product, especially from developers and traders who have integrated with exchange APIs.
