Hi Stackers,
It’s Hypno, been in Bitcoin since 2017, running nodes, playing with wallets, stacking sats, and trying to keep my seed phrase safe, actually.
Last year, I needed a durable backup, but the metal options I was looking at were a hassle to set up, too expensive, or discontinued.
So I decided to build my own.
I’d never designed that kind of product before. So I learned CAD, experimented with 3D-printed jigs, and researched laser-cut metal. I wanted something simple: modular, tamper-evident, easy to stamp with basic tools, and built to last.
I made it for myself. But once I realized how much work it took, and how many of us struggle with the same problem, I figured: if it works for me, why not for others too?
My original plan was to manufacture it here in Thailand. I emailed five local metal shops. Followed up once.
Not. One. Reply.
So I found a shop in China, placed a prototype order, and in under three weeks, I had samples in hand, plus a real human contact who answered emails.
That’s why each unit has “MIC” engraved on it: Made in China. Not because I idealize the system, but because they responded.
I can’t overstate how much that mattered.
This is a family project.
- I built the product, and the website (marketing’s my day job).
- My wife gave feedback and helped with admin, including the import license.
- My son helped package the sets, sorting plates, jigs, keyrings, and cable ties into bags.
- My wife’s sister took the product photos.
- A friend helped shoot the tutorial video.
- My dad placed the first order, just to run through the whole process, and give feedback.
It’s small. It’s real. And it works.
Seed Keys is live: seedkeys.xyz
The first product is a metal backup set, made from 316L stainless steel, with detachable keys, tamper seals, and a precision stamping jig.
Available for single-signature and 2-of-3 multisig wallets.
The kit includes everything except the letter punch and hammer, both standard tools you can find locally, or may already own.
I excluded the punch set mainly because it’s heavy and expensive to ship globally. Given it’s a common size (3mm / 1/8”), it made sense to leave it out. No need to charge you for something you might already have.
Starting small. Aiming to support sovereignty.
Feedback and questions welcome.
