🔁How It Works
Know Your Issuer (KYI) connects token contracts to verified legal entities and minting wallets using a multi-step cryptographic attestation process. It transforms issuer identity verification from a manual, opaque process into a secure, on-chain standard—designed for real-time validation by exchanges, regulators, and DeFi protocols.
KYI is simple for projects to complete, but rigorous enough for institutional-grade verification.
Step-by-Step Process
1. Submit Issuer Information
The process begins when a project submits its token and organizational details to Bluprynt’s KYI portal, including:
Legal entity name and jurisdiction\
Incorporation documentation (e.g., Articles of Association)\
Contact information for legal or compliance personnel\
Token address(es) and the wallet(s) managing mint authority
2. KYB Document Verification
Bluprynt performs a Know Your Business (KYB) review using the uploaded documents and public records to verify:
The existence and status of the legal entity\
That the entity owns or operates the listed project\
That the signer has legitimate control over the business
3. Wallet Signature Challenge
To confirm that the legal entity controls the token contract, Bluprynt issues a cryptographic message challenge to the provided wallet(s). The issuer must sign the challenge using the private key of the wallet that:
Deployed the token contract, or\
Retains mint, pause, or admin privileges
The signature must be completed within a short time window and matches only if the wallet is authentic.
4. Attestation Generation
If the signature is valid and KYB documentation is approved, Bluprynt generates a KYI attestation linking:
The verified legal entity\
The wallet that signed the challenge\
The associated token address(es)
This attestation is published on-chain and made available via API for use by exchanges, DeFi apps, wallets, and regulators.
Attestation Format
KYI attestations are structured to be easily parsed by compliance tools. Each includes:
Token Address
The verified token contract
Wallet Address
The wallet that signed the challenge
Legal Entity
Name, jurisdiction, registration number
Issue Date
Timestamp of attestation
Status
Active, expired, or revoked
Related Disclosures
Linked SmartDocs attestations (optional)
These attestations follow standards compatible with Ethereum (EAS), Solana (Anchor), and Chainlink ACE for broader ecosystem utility.
Revocation and Expiration
Automatic expiration: KYI attestations can have predefined validity periods (e.g., 6 or 12 months)\
Manual revocation: Bluprynt or authorized regulators can revoke attestations if legal status or wallet control changes\
Tamper detection: Signature mismatches or invalid wallets automatically flag tokens as unauthenticated
KYI ensures that every token on-chain can be traced to a known, verified entity—empowering platforms, users, and regulators to trust what they’re interacting with.
