February 2026 marked Self-Custody Month at BOB Space.
@nprofile…9m8v and Seed Keys led presentations on self-custody strategies and workshops on seed phrase security. Participants learned to generate seed phrases by hand, stamp them on metal, and split them for resilience.
Thank you to @nprofile…xl9q for hosting these sessions.

Today marks 17 years since the Bitcoin white paper was published.
In 2008, a vision was introduced: financial sovereignty through cryptography.
It lives on in every user who holds their private keys.
Your recovery phrase is the key to your Bitcoin.
Lose it, and your coins are gone forever.
Seed Keys provides tamper-evident, durable backups built for permanence.
Trusted by those who take custody seriously.
Just own it.

This OP_RETURN may outlast even Seed Keys. But your recovery phrase belongs only on metal.

The bar for self-custody isn’t as high as you think.
If you can birth a child, you can back up a seed.
Your keys. Your responsibility. Your sovereignty.

Seed Keys Launches: Metal Backup for Bitcoin Self-Custody
A new standard in seed phrase protection is now available.
Seed Keys introduces a durable, tamper-evident metal backup made from 316L stainless steel, built to survive fire, flood, and time.

Each backup key set includes:
- 1.5mm thick steel plate with detachable keys
- Precision stamping jig
- Keyring for secure assembly
- Tamper-evident colored seals
Designed for simplicity, the set requires only a hammer and punch to create a permanent backup.
Once assembled, the compact design is easy to store or carry. Small enough for your palm. Strong enough to survive disaster. And fully tamper-evident.
