A soulbound token (SBT) is a non-transferable NFT that represents a person's identity, credentials, or achievements — permanently tied to the owning wallet ("soul"). It was proposed by Vitalik Buterin and E. Glen Weyl.
2. How It Works
SBTs are minted to a wallet and cannot be transferred (or only with issuer revocation). They store verifiable claims — education, memberships, reputation, licenses — on-chain. Wallets accumulate SBTs as a portable, verifiable identity record. Issuers can revoke SBTs under defined conditions.
3. Why It Matters
SBTs enable on-chain reputation and credentials without the transferability that invites speculation. They underpin anti-sybil systems, social recovery trust, and identity use cases. Their non-transferable nature keeps identity claims honest and stable.
