(e.g., with @Blockstream Green)! Powered by @Liquid Network 👊 Disclaimer: While current network fees for Boltz Liquid Swaps render tiny swap amounts economically impractical, we believe it’s crucial to provide flexibility. With Zap Swaps, users of Boltz-powered wallets like Misty Breez no longer need to resort to alternative solutions for occasional tips or Nostr zaps. Happy zapping ⚡️

Call for UI/UX feedback! We are currently debating internally about how meaningful it is to have our Web App expose the technical swap state in the course of the swap (see below). Keep it or remove it? Poll 👇

Common issues/questions

Say adiós to per-swap refund files 👋 Say hola to the Boltz Rescue Key 🛟 At boltz.exchange, we’re dramatically simplifying swap UX: instead of downloading a new refund file for every submarine or chain swap, you’ll now only need one Boltz Rescue Key—downloaded once—and we'll never bother with downloads again 🙏 How It Works 🔑 The Boltz Rescue Key functions as master refund key, deriving a new key for every swap 🖥️ It works on any device and lets you create refunds for all swaps created with it. ⚛️All without compromising the non-custodial characteristic of Boltz Swaps. Why It Matters The Boltz Rescue Key reduces the risk of users misplacing individual refund files and losing access to funds locked in swaps—especially critical for web-based swaps (like boltz.exchange) that require external key backups.

⚡️ Channel house cleaning in progress 🧹 Over the course of the next days, we are: - closing pre-anchor channels - closing stale channels (weeks without activity) - increasing min channel size of our LND to 5 million sats Expect # of public channels to drop significantly. Also, expect us to close channels more regularly from now on and preferably open new channels with our CLN node. Our two nodes: LND:

Network fees for Rootstock -> Lightning swaps just dropped by 50%. Before: 162 sats, Now: 81 sats 🫰 Spontaneous #Lightning payments with your RBTC balance just got even more accessible 🧡 Wen integration to allow your users to spend #Bitcoin on the go? @beexowallet @Rabby_io @EdgeWallet ELI5 of how we did this: we extended our Rootstock swap contract to allow us to claim Rootstock swaps in batches. The more swaps happen in a given time frame, the cheaper it gets. If Rootstock swap volume continues to grow, network fees may drop even more.

Announcement: Today we are making Boltz user support safer! 🛡️ Due to the dramatic increase of scammers, trying to extract mnemonics from our users via DM, we are discontinuing support via DM on all platforms. While we are keeping channels like Discord and Telegram for public discussions, everything that needs private communication, like inquiring about details of a swap, will only be processed using one of the following two communication channels: 1. Via support chat at boltz.exchange 2. Via email to hi@bol.tz This concretely means that if someone tries to make you communicate via any other communication channel, IT'S A SCAM! ⚠️ Your Boltz User Support Squad 🧡

Apart from Bolt12, one more feature of this week's release deserves to be highlighted: 👉 "Any amount chain swaps" 👈 What this means is: you can now send any amount into a chain swap and as long as it's within our min/max range, Boltz will process the swap. This is nice for flexibility (just send vs. decide how much first) but also fixes a major UX issue of boltz.exchange users: - if you accidentally sent too little: your swap still processes with the actually sent amount (instead of failing) and - if you accidentally sent too much: your swap processes with the sent amount (instead of you losing out on the overpaid amount) Two of the most common reasons for failed swaps and support tickets 🤓 DISCLAIMER: only works for chain swaps, not for swaps with Lightning involved Also, we just pushed out a new Boltz Client release implementing Bolt12 and any amount chain swaps.
