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)

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.
