I’ve never found a solution for managing my seed phrases that didn’t keep me up at night
Write it down
Multisigs
Password managers
They all have major flaws
So I decided to build a product for me and all my weird internet friends
Check out the demo in the reply!

Keypo never stores your seed phrase in the cloud.
Instead, seed phrase recovery uses peer to peer connections between your devices (in the case of macbook <-> iPhone, we're using the same low-level API that airdrop was built on).
I like to call it an e-Horcrux.

Most apps use YubiKey for 2FA, which requires a server.
Keypo uses the Yubikey's secure enclave directly to encrypt/decrypt a piece of your seed phrase.
No middleman. No reliance on Keypo to access your seed phrases in the future.

Keypo isn't a password manager. It's a recovery solution for things you don't use everyday but you can't ever lose, like your seed phrase.
Your seed phrase is split into pieces and stored on devices you already own. You can't access each piece without biometric auth or pin.

Last week the SEC published guidance on how to custody your crypto.
And what’s in bold and with exclamation points: Protect your seed phrase!
If you’re still writing your seed phrase on a piece of paper, you should check out Keypo.

Tech companies should name rounds after names like how we do hurricanes.
"We raised a series Anne last year but we're talking to investors about doing a series Bernie this year"

Password managers can be convenient, but beware of using them to back up your seed phrases.
The 2022 LastPass hack led to hundreds of millions in stolen crypto. Here's how it went down. 🧵

Keypo never stores your seed phrase in the cloud.
Instead, we store pieces of it on different devices you own like your phone and your computer.
Each piece is encrypted by the device’s tamper resistant Secure Enclave.
To use each piece requires either biometric auth or a PIN.

Keypo’s core design principle is self custody.
Which means we’ll always make sure we offer products that do not require subscriptions.
So when you need your seed phrases, you're not wondering if your credit card is still on file.
