Our Solution

When you take self-custody of your Bitcoin, your seed phrase becomes the only way to recover your funds if your hardware wallet is lost, destroyed, or stolen. That’s why a durable, offline backup is essential. Our solution delivers on both.

Why Durable Backups Are Critical

Most common storage methods are unreliable and can fail over time. Here’s why they put your seed phrase at risk:

Paper

  • Burns in fire
  • Ink can fade
  • Vulnerable to water damage
  • Easily destroyed over time

Memorization

  • People forget
  • Creates problems for inheritance planning
  • Stressful and unreliable long-term

Digital Storage

  • Can be hacked or compromised
  • Anything connected to a network increases attack risk
  • Malware or device compromise can expose seed phrases

Cloud Storage

  • Can be hacked
  • Third-party custodians introduce additional risk
  • Violates the principle of offline self-custody

Seed phrases require a durable, offline physical backup

Why Metal Backups Are Better

Metal provides a long-lasting physical medium that can survive conditions that destroy paper or digital storage.

Fire-resistant

Crush-resistant

Non-corrosive

Long-term durability

However, not all metal backups are designed equally

Why Stamp Seed Is the Best Metal Backup

Titanium Construction

01

Most solutions use stainless steel.

Stamp Seed uses titanium, which offers:

  • Higher melting point
  • Superior corrosion resistance
  • Will not rust (forms a protective oxide layer)
  • Enables deeper stamping

Single Piece Design

02

Many alternative solutions rely on multiple small parts, including:

  • Letter tiles
  • Screws
  • Rivets

More parts = more potential failure points

These designs can fail due to:

  • Heat exposure
  • Corrosion
  • Crushing damage
  • Component seizure or separation

Stamp Seed uses a single solid titanium plate, eliminating these risks

Deeply Stamped Letters

03

Many competing products rely on:

  • Shallow engravings
  • Laser-etched tiles
  • Light markings

Problems with shallow engravings:

  • Can be scratched away
  • Can corrode away
  • May become illegible over time

If seed words become unreadable, Bitcoin funds may be permanently lost.

Deep metal stamping ensures the seed phrase remains legible even after extreme damage.

Stamp Seed uses professional metal stamping tools to create deep, permanent impressions

Professional Stamping Tools

04

Stamp Seed tools are designed by a team with over 15 years of experience in metal stamping tool design.

This ensures:

  • Clear, consistent impressions
  • Reliable stamping process
  • Easy usability

Each kit also includes a practice titanium plate, allowing users to learn the stamping technique before creating their final backup.

Common Metal Backup Designs & Their Weaknesses

Cassette / Rail Systems

01

Uses individual letter tiles, held in metal cassettes

Problems:

  • Components can loosen or fail under heat, crushing, or basic handling
  • Multiple parts increase failure risk
  • Bending
  • Tile etchings are shallow
  • Only includes the first 4 letters

Cassette / Rail Systems

Engraved Metal Plates

02

Relies on engraving instead of stamping

Problems:

  • Engravings are obscure
  • Scratches can erase markings
  • Corrosion can remove legibility
  • Harder to read

Grid / Center Punch Systems

03

Uses a laser-etched grid to punch dots that correspond to each letter

Problems:

  • Surface damage can create inadvertent, misleading dots
  • If the template corrodes away, decoding becomes difficult

Washer Systems

04

Stores seed words across multiple washers or tiles

Problems:

  • Words are stored on multiple pieces
  • Enclosure components could seize
  • More parts create more failure points
  • Some solutions offer pre-marked washers with shallow letters
