Reads the chain itself
Derives the Metaplex metadata PDA for a mint with hand-rolled ed25519 curve maths, decodes the account, and reads supply and holder spread from the public Solana RPC. No indexer key, no wallet connection.

Prove which Solana token came first.
A public, hash-chained origin registry for token identities. Mintline decodes the on-chain metadata account, finds semantic collisions with an open-weight model that runs in your browser, and files every claim in a tamper-evident ledger anyone can replay.

what it does
02 · compare
Finds the collision
A 22M-parameter sentence-embedding model loads in your browser and compares the token's identity text against every registered origin. The server's lexical comparator is always available as a deterministic floor.

Files it where it can be checked
Every create, verdict, re-assay and retirement appends to a SHA-384 chain per record. Replay recomputes every seal and names the first broken link.
how a score is read
Provenance integrity is a weighted sum of six factors. Weights are published in the API response and printed in every exported dossier.
| band | score | meaning | required action |
|---|---|---|---|
| Attested origin | 75–100 | No meaningful collision, real market depth, and an inspectable identity. | Safe to attest. Record the claim in the registry and keep the dossier. |
| Unregistered | 55–74 | No collision found, but the evidence for a clean origin is incomplete. | Ask the issuer for a signed origin statement before accepting the identity. |
| Collision suspected | 35–54 | The identity text resembles a registered origin closely enough to matter. | Treat the name as unproven. Compare the two metadata records before trading or bridging. |
| Impersonation likely | 0–34 | Strong collision with an existing origin and thin independent evidence. | Do not treat this identity as authentic. Report the mint to the issuer of the matched origin. |

agent interface
Scriptable over MCP
10 typed tools over JSON-RPC 2.0, including three that mutate through the same service layer the UI uses. Retrying an agent mutation with the same idempotency key does not create a duplicate.

safety
Mintline measures observable structure. It does not predict price, does not evaluate whether a token is a good investment, and is not financial advice. A high provenance score means an identity is not obviously impersonating another — it is not an endorsement of the project behind it. Verify anything that matters against the issuer directly.
