Solana signs with Ed25519. Quantum computers break it.

Vantax is a post-quantum security platform written in Rust, starting with Solana. It finds the keys and signatures a quantum computer breaks, adds NIST ML-DSA-87 around them, and enforces who is allowed to do what.

Quantum-risk scanner Edit the code. Findings update as you type.

Browser demo using pattern matching on a few common primitives, including ones Solana code relies on. Your code never leaves this page. The full scanner covers 20 primitive families, is CamelCase-aware and comment-aware, walks directories and sets CI exit codes; it runs on the Vantax API with a Pro or Enterprise plan.

Why Solana first.

Every Solana transaction is authorized with Ed25519. Wallets, program upgrade authorities and validator keys all depend on a scheme that Shor's algorithm breaks on a large enough quantum computer.

Vantax cannot change Solana's base signatures. It works as a layer around them, and this part is in progress: scanner rules for Solana codebases, PQ-signed attestations and audit trails that sit next to programs, and guidance on hybrid verification.

Twelve crates. Each answers one question.

A flaw in one component never carries the authority of another. The scanner never holds a signing key, so it has none to leak.

What's included

Engineering and integration work, not a security audit. Half to start, half on delivery. Your secret keys never leave your machines.

Launch your own chain.

Your own post-quantum blockchain, on your own servers. Pick the name, ticker and supply, pay once in SOL, and download a licence signed by Vantax with the node software: validators, sync, an API and a block explorer in one program, with ML-DSA-87 signatures on every transaction and block. You host it. Vantax takes no cut.

Launch a chain

Rules the code enforces.

Each of these is refused in code, not left to configuration.

  • No signing oracle.The gateway signs only its own attestations, from a closed set, under a fixed domain tag. Customer keys stay with the customer.
  • A valid signature is not authority.Verification and authorization are separate checks. Revoking an issuer revokes everything it signed.
  • Humans own irreversible decisions.Sentinel suspends automatically. Revocation always escalates to a person, and protected identities are never contained automatically.
  • A threshold of one is refused.Bridge signers are counted by distinct fingerprint, and the circuit breaker never resets itself.
  • History survives rotation.Keys resolve by timestamp, so old signatures still verify. The audit log is hash-chained, so editing one entry breaks every entry after it.

Live, and open to inspection.

The API is running, nine of the twelve crates are open source, and the whitepaper sets out the design, the threat model and the limits. The cryptography is NIST FIPS 204 ML-DSA-87. Vantax hasn't had an independent third-party audit yet, so don't rely on it alone to custody value until a review covers your deployment.

Official token address.

$VANTAX is the Vantax token on Solana. This is its only official contract address. Any other token using the Vantax name is not ours.

Holding $VANTAX? A wallet with at least 1,000,000 $VANTAX can get a Vantax API key with the migration scanner. Sign a message to prove the wallet is yours: no transaction, no tokens moved. Get holder access

Buy back and burn. 5% of every Vantax sale buys $VANTAX on the open market and burns it. Every burn links to Solana. See every burn

Check the address character by character wherever you paste it. Vantax will never ask for your seed phrase or private key, and never asks you to send tokens to claim anything. You don't need the token to use any Vantax product. This is not financial advice or an invitation to buy; cryptoassets are high risk and you can lose everything you put in.
