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.
Introducing: Keypo

I gave Claude a wallet. It can do anything on-chain, but it can't steal my keys. They're in MY Mac's Secure Enclave. Not the cloud.
Introducing the Keypo Wallet CLI: your Mac as a programmable hardware wallet for AI agents. Open source.

Just an observation: the Kalshi ads with Terrell Owens look a lot like the FTX ads with Larry David (in terms of vibe)

2nd update, found a programmatic solution.
Discovered claude code's orchestration feature (code.claude.com/docs/en/agen...).
That + a simple slash command + a couple short agent files and everything is automated!
Feel free to use my setup:
I wish there was a way for my claud code sessions to "talk to each other."
Two simple examples:
1. I like having one session generate a plan and another review it and provide feedback. Rn I have to c/p the plan and feedback between two sessions.
2. Sometimes I have sessions running on different machines (one in a serv

Quick update: been working on the plugin and you can now install it directly from Openclaw!
openclaw plugins install @coffeexdev/xmtp

It's insane how good AI coding tool shave gotten IF you have a way for it to test it's work.
Without self-verification, it's pretty good but not mind blowing.
Huge opportunity to disrupt embedded hardware (i.e. wearables) because it's really hard to test without physically touching the devices.

The worst part of being a solo founder: you can't fire someone and immediately increase your net worth by 20%

Your private key is a single point of failure.
Every wallet has a PK: @privy, @metamask, @rainbow, @phantomwallet, etc.
Keypo.io splits your PKs across devices using Shamir Secret Sharing + Secure Enclave, backed by biometric auth. No more writing them down.

Update: came up with bandaid solution.
Wrote a skill called "review-plan" that takes text as input and outputs feedback. Still have to c/p the plan and feedback but at least save time on typing the prompt.
Here's the skill if anyone find's it helpful!

Password managers aren't built for high-value secrets like seed phrases and 2FA codes.
Keypo.io is. Here's why:

Building self-custody/open source agent wallets is a very important problem space to go after.
If you're already trusting an agent with money, you shouldn't need to also trust a 3rd party API to let your agent spend your money.
At that point, might as well just give it a CC.

Just got a notification that my 1PW subscription is going up this year.
In a world of software abundance, using a self-hosted PW manager like keypo.io makes more sense than ever.

TIL phishing attempts are happening by snail mail now 🤦♂️
Reminder to never enter your seed phrase into a browser. It's really hard to know whether a site is malicious or not.
A big reason why I built keypo.io to be local first. Your seed phrase never touches the cloud.

I'm really excited about the new keypo.io app (coming soon).
Biggest change is it's mobile first so you don't need a mac computer to use it.
Before going live, would love to do some user interviews to get feedback on the app.
If you're interested please reply here! Willing to comp for time too.
