Verifiable
Checkable by anyone
A credential is cryptographically signed to your handle — verify it against your keys, no issuer lookup that outs you.
📜
Credentials & Sign
Prove it, sign it — post-quantum.
Hold credentials others can verify, and sign documents with a post-quantum signature bound to your handle. Provable and portable — without revealing who you really are.

Attestation without a paper trail to you
A credential is a signed statement about your handle — a reputation, a membership, an approval — that anyone can verify against your keys, and that you can present without exposing your identity. Signatures use ML-DSA-65 (FIPS 204), so proofs made today stay valid against a quantum adversary tomorrow.
Post-quantum
Signed to last
ML-DSA-65 signatures keep a document or credential provably yours even against future quantum attacks.
Unlinkable
Prove without exposing
Present what you need to prove, bound to your pseudonymous handle — not to your real-world identity.
How it works
Receive or issue a credential
A counterparty signs a statement about your handle, or you sign one about theirs — portable and self-verifying.
Sign a document
Attach a post-quantum signature to a file or agreement, bound to your identity and the moment.
Anyone verifies it
A recipient checks the signature against your keys — provably yours, with no central authority in the loop.
📜
Proof you own
Reputation, membership and signatures that travel with your handle — verifiable everywhere, linkable to no one.
