Shop Self-Custody for Bitcoin Mining
Bitcoin self-custody hardware. Hold your own keys — this is the bench side of it: air-gapped signing-device kits you build and verify yourself, seed-backup tooling, and the printed parts that keep a signing device on the desk instead of in a drawer.
Nothing in this category holds your Bitcoin, and no product can make you safe. That part is your process, your backups and your threat model. What D-Central ships is hardware you can inspect: the SeedSigner DIY Kit — stateless, no WiFi or Bluetooth radio, QR codes in and QR codes out — the BlockMit washer jig for punching a seed backup into metal, and D-Central-designed cases and mounts printed in Montreal, QC.
Shoulders of giants. We did not invent these designs. SeedSigner is an independent open-source project released under the MIT licence; the BlockMit washer-stamping design is released under CC BY 4.0. We build, support and ship them, and we credit the people who did the design work.
Reading before buying: the signing devices reference, the wallet sovereignty matrix, the recovery and derivation-path matrix, and the sovereignty hub.
Built to order, shipped from Canada. Not Amazon.

Before you generate a seed
Self-custody is a process, not a purchase. Read what the device actually does, check how your wallet derives and restores, then plan the metal backup and who inherits it.
