This is an exciting one 🔥

Since Conner’s first publicly documented atomic 🔁 on ⚡️ between BTC & LTC back in November 2017 (shout out!), we spent quite some time attempting to reproduce the whole thing… and finally did it! Admittedly, it’s an old LND branch and required quite a bit of hacking and definitely will be done differently in production, but it’s just beautiful to see the BTC/LTC swap happening instantly. The swap is executed directly between two LND nodes, preserving privacy (you won’t find a trace of the swap on-chain ㊙️) and is completely trustless, which is the point of atomic swaps!

LND contributor offerm is the guy behind the scenes pulling this off (kudos)! Enough words for now, watch our lightning dev Daniel McNally demoing the swap:

What does that mean for Exchange Union?

It’s tangible proof that the underlying technologies powering Exchange Union (cross-chain atomic swaps on payment channels) work in practice. If you want to learn more about Exchange Union, read this.

In the meantime we are heads-down, focusing on getting this swap production ready and merged into LND master at some point (I know you guys are 400% busy Elizabeth Stark, better get Laolu & Conner mentally prepared for some tedious reviews 😅). Apart from that, we plan to launch some (very) early stage testing of our XUD node with selected exchanges next month. Pieces are starting to fall into place with XUD.

We did lightning swap #2 on this 🌎, who will be #3 & #4? Follow our guide and tweet a video showing the swap with #lnswap @exchange_union :

See you at #LightningHackday in Berlin on June 23rd — rumor has it there will be some nice lightning swag for everyone!

Happy swapping,
