Giving an AI agent the ability to spend your bitcoin sounds like a terrible idea. In early April 2026, Nunchuk released a tool that makes it a considerably less terrible idea: nunchuk-cli, a command-line interface that lets AI agents operate inside Nunchuk group wallets, with the human holding ultimate control. It shipped as two MIT-licensed…
Why 3-of-4, and why Nunchuk Most shared custody setups are 2-of-3: two keys can move the money, one can be lost. A 3-of-4 raises the bar on both sides. You can lose one key and still spend. An attacker needs three. For a small team or a family treasury, that tradeoff is often worth it….
Why this list exists The multisig wallets everyone knows fit on one hand: Nunchuk, Sparrow, Specter, Electrum, the big custodial coordinators. But there is a stranger layer underneath. Solo developers and small teams are building multisig experiments on Stacker News: timelocked vaults, duress-resistant key sets, descriptor QR codes, threshold signing without hardware. Most will never…
The Lightning problem Escrow on a P2P exchange means someone holds the coins until both sides deliver. With onchain bitcoin, that is a plain multisig: buyer, seller, and the platform as arbiter in a 2-of-3. It works because onchain coins sit still. Lightning coins do not sit still. They live in channels, with balances that…
Every few years a wallet promises to break every rule. FrostSnap is the current candidate: a Bitcoin self-custody system built on FROST, a threshold Schnorr signing protocol, where your devices generate the wallet together and the full private key never exists anywhere, not even for an instant. In May 2026, a skeptical Stacker News post…
Assisted multisig sells you convenience: a company holds one key in your quorum, handles coordination, and helps you recover if things go wrong. The price is usually quoted in dollars per year. In August 2026, a Stacker News poster added up the other price, denominated in privacy, and found it steep. What the co-signer sees…
Multisig is the strongest self-custody setup most people can build. It is also the setup most people never finish, because doing it yourself involves a long chain of careful steps and every one of them matters. In February 2026, Stacker News user @blockdyor shared a full DIY multisig guide built around Nunchuk, the coordinator app…
“Just back up your seed words” is the most repeated and most incomplete advice in Bitcoin self-custody. It works for single-sig. The moment your locking script is more complex than one signature, seed words alone do not recover your wallet. You need the descriptor too. And here is the uncomfortable part: Bitcoin has no comprehensive…
Best Hiding Spots for a Seed Phrase That Burglars Miss The best hiding spots for a seed phrase that burglars miss are the ones a burglar would never spend time on: sealed inside the casing of an old device you never use, behind a wall panel in a room they will not enter, or buried…
"Lots of people are working hard to convince you that a simple step by step guide for using bitcoin core is easier to backdoor than a hardware wallet. Grok is destroying them though so rest easy." That is JW Weatherman, the author of the original YetiCold guide, posting on X in September 2026. He is…
