What Are Soulbound Tokens?

SBTs are a token variant conceived in 2022 by Vitalik Buterin (with Puja Ohlhaver, E Glen Weyl):

  • Permanently linked with an identity
  • Cannot be transferred between wallets
  • "Soul" = persistent identity, "bound" = bound
  • Original use case: credentials (diplomas, certificates)

Edition Overview

Year of the Horse 2026 (March 2026):

  • 3 unique horse designs by Chrissy Lau
  • Price: AUD 15 per DigiStamp
  • Theme: Lunar New Year, Fire Horse 2026
  • First SBT crypto stamp worldwide

Anti-NFT-Hype Strategy

Australia Post deliberate distancing from NFT hype backlash:

  • 2021-2024: NFT market crash, rugpulls, hacks
  • 2025-2026: Anti-speculator sentiment among collectors
  • AU response: SBT instead of NFT — serious, collector-focused

GM statement: "DigiStamps marks a defining moment in the history of collecting".

No-Wallet-Required

A critical UX innovation:

  • No app download needed
  • No wallet setup needed
  • No account creation needed
  • DigiStamps displayed online as unique collectable

Drastically lowers Web3 entry barrier — comparable to EPG built-in wallet, but structurally different (SBT instead of transferable NFT).

StampFinity Implementation

StampFinity (Austria) as tech partner is structurally central in the crypto stamp space:

  • AT pioneer tech provider (2019)
  • GG, UAE, FO + others
  • First SBT implementation with Australia Post

This tech cluster position shows structural centralization: few tech partners serve many issuers.
