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.

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.
