They are not linkable for the public observer as amounts are blinded on Liquid and additionally Taproot Swaps generally made swap transactions indistinguishable from any other regular transaction.
BUT we do have the link! Therefore, privacy on Lightning is a bit better as one can't tell with certainty where a Lightning transaction was sent from.
That being said, Boltz respects privacy but is NOT a privacy solution or a substitute for e.g. coinjoins.

Chain Swaps let you swap directly between Liquid and the Bitcoin mainchain and lay the foundation for more chain-to-chain pairs in future.

Not directly. You can use Boltz to swap from Lightning into Liquid, (best directly use a Sideswap destination address) and then Sideswap to go from L-BTC to USDT.

CLN's "pay this lightning invoice" is pretty broken. This PR makes it easier for users to use the alternative "mpay" instead.

Michael wrote mpay - a new pay plugin for CLN because CLN's pay is... not behaving as we expexted. Now Rusty of the CLN team pushed a commit adding the option for CLN to override pay with mpay.

It's a protocol upgrade that we are beta testing that allows us sending transactions with 0.01 instead of 0.1 sats/vbyte. If all goes well, it will be generally available later this year.

Today we are drastically reducing network fees for Liquid swaps - finally making ⚡micropayments via wallets like Aqua, Marina, Bull Bitcoin or Helm economically viable 🫰
Network fees drop from previously ~400 sats total to ~40 sats total🤯

Probably nobody is considering using the mainchain anyways rn, but we temporarily disabled #Bitcoin mainchain swaps as a safety measure til things calmed down a bit.
Happy halving!

We know the chain origin and final lightning destination in Chain -> Lightning Swaps. We do *not* know the origin in Lightning -> Chain swaps but, the chain destination. We always know amounts.
Publicly, privacy is not too bad with confidential transactions hiding asset and amounts on Liquid (but not tx graph), and with Taproot Swaps it's additionally pretty tough to tell that a tx was part of a swap.
Will start a FAQ section in docs with this as we get this question a lot. Thanks for asking and pushing for transparency!

#Bitcoin community, help a fellow Bitcoiner to recover funds! Reposts & @'s highly appreciated🙏
Anyone with contacts to a tech-savvy person at Kraken please relay this! The issue is not easy to get across, user tried with Kraken customer service for two weeks to no avail.
What happened:
- user accidentally pasted Kraken's ln node pubkey as "destination" in a Boltz swap
- turns out node pubkeys are valid P2PKs (the thing before there were Bitcoin addresses), so the swap went through
- now the funds are sitting in a P2PK which Kraken should have keys for
Here the P2PK: https://mempool.space/address/02f1a8c87607f415c8f22c00593002775941dea48869ce23096af27b0cfdcc0b69
Which matches:

Kraken should be able to return the funds using their lightning node's key to sign the transaction.
We know this is a big ask and some might not even consider the amount worth the effort but for us this is about principles: Returning funds to a fellow Bitcoiner, user of Kraken & Boltz 🙏

We were essentially offline already for the past hours without noticing it because LND *deadlocked* itself once more in the weirdest way - invoice creation just stopped working reliably.
