Bitcoin inheritance, done right. Non-custodial multisig, on-chain timelocks & guided recovery. Zero KYC.

Shorts

Sorry to hear if you were impacted by today’s Trezor data leak. It’s been a hard few weeks for Bitcoiners: a series of security incidents that directly impact those who self-custody, the very people who keep Bitcoin resilient and decentralized. Strengthening self-custody, at every layer, matters more than ever. At Nunchuk, we’ve kept shipping through it. New today in our latest mobile release: ✅ Ledger over Bluetooth on iOS ✅ Ledger over Bluetooth & USB on Android Nunchuk now supports a dozen hardware signers across every major signing method: Bluetooth, USB, NFC, and fully air-gapped via files or QR codes. Coming over the next four months: • More hardware options for the inheritance key (for both off-chain and on-chain timelock protocols) • BitBox Nova mobile support (Bluetooth & USB) • Blockstream Jade Bluetooth support • Satochip: an NFC card that supports BIP39 seed phrases and is a MuSig2-capable signer Multi-vendor multisig has never been easier to set up. If you want a demo of a specific combination of hardware signers, reply below and we’ll make it.

Multi-vendor multisig demo👇 One multisig, five different hardware vendors, connected five different ways all on mobile: ✅ Ledger (Bluetooth) ✅ Trezor (Bluetooth) ✅ Blockstream Jade (QR) ✅ FOUNDATION Passport (QR) ✅ TwentyTwo Devices Portal (NFC) No single point of failure. Built on open standards. Everything stays end-to-end encrypted through the whole setup, and there’s a built-in E2EE chat for coordinating group setups. Works whether you’re setting it up for yourself or splitting keys across a few people. All keys can be geographically distributed. Keystone Hardware Wallet, SeedSigner, selfcustodykrux, TAPSIGNER also work. BitBox and Satochip on mobile coming soon. (Devices shown are for demo purposes, not a ranking or endorsement.)

The Bitcoin agent key can now live in a COLDCARD Mk4/Mk5 in HSM mode. Even if the host machine running your agent is fully compromised, the signing key stays isolated in hardware. The attacker gets nothing useful. Bitcoin agents with bounded authority. Now with HSM-grade key security.

Prompt: “Create a 3-of-4 wallet. After 2 years, it becomes 2-of-4. After 5 years, it becomes 1-of-4.” What this is: A decaying multisig created with an AI agent using Nunchuk CLI + Agent Skills. No Miniscript knowledge needed. It starts as 3-of-4. After 2 years, it becomes 2-of-4. After 5 years, any 1 of the 4 keys can spend.

Miniscript support is now live in Nunchuk CLI + Agent Skills. This demo shows a decaying multisig: 2-of-3 today → 1-of-3 after Jan 1, 2030. Shared Bitcoin wallets shouldn’t stop at basic multisig. Build Bitcoin agents with richer Bitcoin-native control.
