🧠What Is KYI?
Know Your Issuer (KYI) is Bluprynt’s token authentication tool. It enables projects to cryptographically prove that a token was issued by a verified legal entity and that the controlling wallet holds legitimate minting authority.
Why KYI Matters
In traditional finance, securities are tied to registered issuers and disclosures. In crypto, any wallet can deploy a token with no link to a verified identity or legal entity.
This results in:
Impersonation of legitimate projects
Fraudulent airdrops and token listings
Increased regulatory exposure for platforms and investors
KYI fixes this by publishing a verifiable attestation that ties:
A token contract address
To a minting wallet address
Controlled by a verified legal entity
Key Benefits
For projects:
Establish official token provenance
Prevent copycats from undermining your market or confusing users
Improve eligibility for exchange listings and institutional capital
For platforms:
Easily verify whether a token is official
Use KYI as a listing requirement or policy gating mechanism
Reduce exposure to reputational and compliance risk
For regulators:
Identify issuers responsible for token deployment
Trace wallet activity linked to registered entities
How It Works
The following outlines how to leverage the KYI application:
Step 1: Open the KYI Application
Go to the home page of your account and click on "Authenticate Asset" under the "Know Your Issuer (KYI)" card.
Step 2: Fill Out the Token Details
Complete the "Token Details" section by filling out essential information about the issued asset.
Step 3: Verify the Issuing Wallet(s)
To complete KYI, the asset issuer must prove control over a wallet with mint authority by signing a Bluprynt-generated message via wallet extension, CLI, or HSM.
Step 4: Finalize Business Verification
Fill out the business details section regarding the asset issuer. Such a process will include completing KYB (Know Your Business) verification if the asset issuer hasn't already done sone when creating an organization account on Bluprynt.
Step 5: Submit the Asset
Once you have completed all of the other sections, the asset issuer may press "Submit" and finalize the KYI process. The asset's KYI application will go into "pending" before being approved.
Step 5: Generate the KYI Attestation
Once the asset is approved, two critical things occur:
The asset has a W3C (DID) and ONCHAINID compatible identity created for itself.
A KYI attestion linking the asset issuer's onchain identity and the asset's onchain identity is created and published on the asset's blockchain network.
Anyone may verify the KYI attestation via the asset's details page. Additionally, the KYI attestation and asset identity are also registered on the Bluprynt registry, which is also publicly facing.
What’s in a KYI Attestation?
KYI (Know Your Issuer) brings verifiable identity and accountability to token issuance—without compromising composability or the permissionless nature of Web3. It creates the foundational link between:
The off-chain entity (the asset issuer and its legal status)
The on-chain asset (the token contract and issuing wallet)
The asset’s disclosures and licenses (via SmartDocs attestations)
Without KYI, there's no cryptographically provable relationship between the legal issuer and the asset they claim to issue. This breaks the compliance chain and introduces risk to both users and regulators. KYI solves this by generating a signed, tamper-proof attestation containing:
Token contract address
Mint-authority wallet address
Verified entity name, jurisdiction, and registration number
Timestamp and expiration
Optional link to related SmartDocs disclosures and licenses
These attestations are machine-readable and interoperable with major block explorers, token registries, and compliance systems. KYI enables automated policy enforcement, investor trust, and regulatory alignment—all while preserving the permissionless flexibility that makes Web3 powerful.
