Signing Room

Multisig coordination just leveled up. ⬆️ SigningRoom v1.6.0 is here: 👥 Guest Display Names (Witnesses) 🔎 Address Filtering 📄 Enhanced Enterprise Audit Logs 🔒 Privacy-first Identity Purging Check out the new feaures below! 👇 #Bitcoin #Privacy #SigningRoom

Announcing the BIP Draft for Blind Relay: Stateless PSBT coordination via E2EE WebSockets. Bridging the gap between airgapped security and real-time coordination without the honeypots. BIP Draft: github.com/scarlin90/bip-… #Bitcoin #Multisig #Privacy #FOSS

SigningRoom v1.3.0 is live🚀 How do you get a secure room link from your laptop to your mobile wallet without pasting it into Slack, Email, or Telegram? Solution: Secure QR Codes. Coordinates your multisig securely & metadata free. #Bitcoin #Multisig #Privacy #OpenSource

Ephemeral sessions. Zero knowledge. Stateless coordination. We are proud to introduce our parent laboratory: Stateless Research. The science behind the signal. statelessresearch.com #Bitcoin #multisig #privacy #stateless

The whitepaper is live "The Stateless Pattern: Ephemeral Coordination as the Third Pillar of Digital Sovereignty" We have formalized the architecture behind SigningRoom.io Read the preprint: arxiv.org/abs/2601.17875 @HRF @OpenSats #Bitcoin #Multisig #Privacy #OpenSource

I deleted 30% of the Signing Room codebase. No Lightning Payments Multisig coordination should be a public good, Scaling security matters more than collecting sats Signing Room is now a 100% free, stateless security utility for the #Bitcoin community. signingroom.io

@saylor Ending the year with more #Bitcoin is the goal. Keeping it sovereign is the mission. 🛡️ Are you coordinating that multisig with stateless tools yet? I just launched Signing Room to help whales coordinate offline signatures without a database trail.⚡️ signingroom.io

Did you end the year with more Bitcoin than you started with?

@adam3us @adam3us Tick tock next block. ⏳ Every block is a chance for better PSBT coordination. I just launched Signing Room to make multisig signing as relentless as the chain itself. No database, no tracking, just stateless E2EE coordination.⚡️ signingroom.io

tick-tock, next block🟧

@Blockstream @BlockstreamJade Jade is a beast for single-sig. 🛡️ If anyone is using Jade in a Multisig setup (e.g. with Sparrow), the hardest part is usually moving the PSBTs between signers. I built a free, stateless room to merge those PSBTs instantly without saving data. signingroom.io

The Blockstream app makes Bitcoin self-custody simple from day one.| Face ID or PIN, done. Your Bitcoin in your control. No exchanges holding it. No one else with access. Stacking more? Secure it with @BlockstreamJade for cold storage.

@fartface2000 100% agreed. The ability to verify is the whole point. The next step in 'basics' is making Multisig accessible. Right now, verifying and merging PSBTs usually means insecurely emailing files back and forth. I built a tool to fix the coordination issue: signingroom.io

We need to get back to basics. Bitcoin isn’t about CAGR. That’s a byproduct, not the point. The point is self-custody. Verifying your own UTXOs. Running (or trusting someone you know running) an archival node that can independently verify the supply and every coin that’s ever existed. Value isn’t assigned by models or influencers. It’s subjective. Each individual decides what a bitcoin is worth to them. Some value it more, some less , that will always be true. The market prints a price, but that price only matters if you’re buying or selling right now. Otherwise it’s just noise. Know what you own. Know why you own it. Know why you’d keep buying it. And if that’s not your cup of tea that’s fine. Bitcoin doesn’t need unanimous belief. It needs individuals who understand it.

@COOWN_crypto Spot on about recovery drills. 💯 Most teams skip them because the actual workflow of passing PSBTs back and forth is painful and slow. I built a stateless coordination tool to make those drills instant (and secure) without needing to email files. signingroom.io

⚠️ Common multisig mistake: treating it like a set-and-forget lock. Risks grow when keys sit on personal phones, signers go inactive, or the quorum is too high to meet fast. Result: stalled payouts or a single lost device blocking funds. How to avoid it: - Keep keys on separate, secured devices 🔑 - Set a quorum you can meet within 24 hours ⏱️ - Rotate signers on role change and run recovery drills 🧪 - Add per-transaction limits and daily caps If you need a non-custodial wallet that enforces rules and approvals for stablecoins, BTC, and tokenized assets, COOWN fits that workflow without custody.

@Trezor @nufiwallet Hardware security is the standard. 🔒 For Trezor users who are strictly focused on Bitcoin Multisig, I built a stateless tool to help you coordinate/merge PSBTs without emailing files. It's ephemeral, client-side encrypted, and FOSS. signingroom.io

We have the perfect match 💚 NuFi now integrates with Trezor via Trezor Connect. Use your Trezor Safe 7 to access NuFi's multichain capabilities with hardware-level security — so you can explore more, while your keys stay safely offline. Try it now. @nufiwallet

@bitshala_org Great breakdown. The friction point is usually moving the actual files (email/USB). I built a FOSS tool to fix this 'transport layer' problem. It creates a stateless, encrypted room to merge signatures live. Perfect for students testing flows: signingroom.io

🧵 Week 3 of LBTC cohort - Diving deeper into Bitcoin tech ⬇️ 🟧Question: What is a PSBT and why is it useful? → A PSBT (Partially Signed Bitcoin Transaction) is a standardized format (BIP 174) for Bitcoin transactions that aren't fully signed yet. → It includes the unsigned transaction data plus extra metadata (like UTXOs, derivation paths, and partial signatures). Why useful? → Enables secure offline signing (e.g., air-gapped hardware wallets sign without exposing keys online). → Simplifies multisig setups (multiple parties sign the same tx independently, then combine). → Boosts wallet interoperability (different software/hardware can collaborate easily). → Powers collaborative txs like CoinJoin for better privacy. Super practical for real-world Bitcoin use! 🚀 What did you learn this week? 🧐 #Bitshala #Bitcoin
