Soulbound NFTs

Web3 lacks primitives to represent social identity, resulting in dependencies on centralised web2 structures.

For example, NFT artists rely on centralised platforms and web3 participants rely on custodial wallets managed by centralised entities.

Non-transferable soulbound tokens (SBTs) enable a richer social experience.

It facilitates trust networks of the real economy, community wallet recovery, and sybil-resistant governance.

Accounts or wallets holding non-transferable SBTs represent commitments, credentials, and affiliations.

These SBTs can empower applications such as undercollateralized lending, decentralised key management, and creating novel markets.

SBTs correspond to affiliations, memberships, and credentials, issued or attested by counterparties.

They can be self-certified and issued by individuals, companies, or institutions.
