A New Era of
Trustless Authenticity.
Fakes are impossible. Every certificate is verifiable on-chain. Creators, celebrities, and institutions sign digital assets as ICRC-7 NFTs — with cryptographic proof that can never be forged.
The Trustless Authenticity Platform
On-Chain Certificates
Every signed copy is an ICRC-7 NFT with cryptographic proof. Fakes are mathematically impossible.
Multi-Currency Marketplace
Trade signed copies and collections in ICP, ckBTC, ckUSDC, and ckUSDT with atomic payment transfers.
Certificate Issuers
Celebrities, institutions, and governments create verifiable digital certificates for authentic works.
Multi-Signer Support
Asset owners can invite co-signers. All signatures are embedded in ICRC-7 token metadata on-chain.
How It Works

Certificate Issuers upload digital assets — images, audio, documents, or videos — and organise them into collections.
Sign & Certify
Sign your asset to create unique numbered copies, each minted as an ICRC-7 NFT with a verifiable certificate.
Set Your Price
Price each signed copy individually — free or paid, direct purchase or auction — in any supported currency.
Sell in the Marketplace
Collectors buy verified signed copies knowing every certificate is cryptographically authentic and on-chain.
