Cryptographic launchpad · Solana

Launch with proof.

Create tokens on Solana with verifiable declarations, cryptographic launch records, and transparent provenance. The declaration and what the chain says afterwards are both published, even when they disagree.

How OBSIG works

Three stages, and a record at each one

Each stage leaves a sealed entry you can recompute yourself.

Learn how it works
01 — Declare

Commit the declaration

Name, ticker, supply and intent, signed by your wallet and sealed before the coin exists.

02 — Launch

Build it and sign it

The transaction is built from that declaration, simulated, and shown account by account. Your wallet signs it, never this server.

03 — Verify

Agree, then seal

Two independent endpoints must agree on the whole transaction before anything is sealed as launched.


Cryptographic provenance

Each seal commits to the one before it

A seal is a sha256 over the whole entry, and every entry carries the digest of the previous one. Editing an entry later changes its digest, which breaks every seal after it. Anyone holding a later digest can prove that, including against us.

Each digest is a sha256 over the canonical JSON of its own entry. Recompute them from the raw record.

Declared, then read

What you signed is sealed before the coin exists. A worker re-reads the chain on a schedule and seals what it finds, each reading carrying its slot.

Published when they disagree

If a later reading contradicts the declaration, both stay on the token page. Nothing is quietly replaced, because a record that can be tidied is not one.

Recomputable by you

Every preimage field is served as JSON with the recipe, so you can compute the digests yourself and disagree with our verdict.

Declared on OBSIG

Every token on this launchpad, with its sealed declaration and the slot each reading was taken at.

Nothing has been declared yet

No token has been sealed on this launchpad. When one is, it appears here with its declaration, its seals and the slot each reading was taken at.

Be the first

Every launch leaves a record.

OBSIG does not promise a coin will do well. It promises the record cannot be changed.
