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.

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.
