Definition. Identity attestation on Solana is the issuance and holding of identity credentials — non-transferable soulbound KYC tokens that prove verified status, a role owned by H33-Key, which holds and issues keys, secrets, and credentials (custody, rotation, issuance). This page inherits that verb: it explains how verified-status credentials are issued and custodied so that on-chain contracts can gate access, relative to that role.
Boundary. This page is about issuing and holding the identity credential. For the portable 74-byte post-quantum attestation the credential references, see H33-74, which produces it; for rendering the independent verdict when a credential is checked on-chain, see Verification; to prove attributes without revealing the underlying data, see the ZK Platform. Solana here is an ecosystem chain the credential anchors to, not an owner of the credential. This page uses those mechanisms; it is not itself either one.
Solana's speed and low cost make it ideal for identity attestation. Issue soulbound tokens as KYC credentials, verify on-chain for DeFi access.
Implementation
H33 issues Solana-based attestations after verification. Non-transferable tokens prove verified status. Smart contracts gate access.
Frequently Asked Questions
What does a Solana identity attestation actually hold?
It holds a non-transferable soulbound token that proves verified status after KYC. Issuing and custodying that credential is a role owned by H33-Key. Solana is the ecosystem chain the credential anchors to, not the owner of the credential itself.
How is the credential checked when a contract gates access?
When a credential is checked on-chain, the independent verdict is rendered by Verification. The credential can reference a portable 74-byte post-quantum attestation produced by H33-74 so the same proof travels across systems.
Can a holder prove verified status without revealing personal data?
Yes. To prove attributes without disclosing the underlying data, the flow uses the ZK Platform, which proves claims without revealing them. This page uses that mechanism; it is about holding the credential, not proving in zero-knowledge itself.
