How a disabled hardware-RNG path and 32-bit reseed constrain entropy in affected COLDCARD firmware and expose generated secrets.
Turns out most people use a bitcoin wallet the same way they'd use any wallet:
To hold their own money and spend it on their own terms.
Our new report with Global Digital Finance and Block, in partnership with TRM Labs and Coinbase, shows this in the data — and it's why we're building Bitkey for you:
True ownership of your money, no middleman holding your keys.

This is about as cheap as buying bitcoin gets.
Pick @Cash App in Bitkey and you'll pay zero trading fees and zero spread, so more of your money turns into sats.
Most wallets stop at setup. Bitkey is built for everything after.
Bitkey builds recovery, inheritance, and on-device verification in from the start.
No seed phrase. No subscription.
Self-custody used to mean “don’t make a mistake.” Bitkey assumes you will.
The new screen verifies recovery, inheritance, and security changes — not just transactions.
That’s what full protection actually looks like.
Meet the new Bitkey.
No seed phrase.
Multisig by default.

Another month. Another cycle of noise. Self-custody is still the answer.
And bitcoin is still bitcoin. Conviction compounds.
Q2 starts tomorrow. Stay sovereign.
We didn't build Chain Code Delegation to keep it.
We built it as an open bitcoin improvement proposal so any wallet can implement it. Privacy in collaborative multisig should be the standard.
Bitkey
Not our keys, not our business
People come for the price. They stay for sovereignty. It shouldn’t be complicated.
Multisig at its finest. Built for real-world recovery.

Bitcoin Self-Custody Wallet, App & Hardware
Bitkey is a bitcoin self-custody wallet with an app, hardware device, and built-in recovery, so you keep your private keys without losing access.
Financial privacy is about ownership. It's about the baseline assumption that your money is your business.
What does financial privacy mean to you?
In single-sig self-custody, one exposed seed phrase ends the game. With Bitkey's 2-of-3 multisig, no single key can move your funds on its own.
Higher cost to attack. Lower risk for you. That's the design: https://bitkey.world/learning-hub/bitkey-basics/security/bitcoin-security#security-principles
Your address is your business. When you buy Bitkey, you can pick it up at a local retail location instead of having it shipped to your home. No shipping address.
No paper trail. Privacy starts at the point of purchase: https://bitkey.world/learning-hub/bitkey-basics/privacy/bitkey-privacy#pickup-points
There's usually a moment.
An exchange going down.
A withdrawal denied.
A headline that hits too close.
What was yours? What finally convinced you bitcoin self-custody wasn't optional?
"Tools like Bitkey make bitcoin so much more accessible to the average person." — Natalie Brunell. If bitcoin is for everyone, then the tools should be too.

With Bitkey, you can designate a beneficiary: no seed phrases, no instructions to lose. Your bitcoin, your terms. Generations from now.

Inheritance is live. Here’s how it works.
