KILT Protocol

KILT Protocol is a decentralized identity infrastructure running as a parachain on Polkadot, developed by BOTLabs with its mainnet launched in 2021. The protocol is built around three roles: the Claimer who creates a statement, the Attester who issues a signed credential, and the Verifier who checks authenticity without touching raw personal data. Credential structure is defined by CTypes schemas, and only cryptographic hashes are recorded on-chain rather than the underlying information, preserving privacy while keeping verification possible. An open SDK supports integrations such as SocialKYC, DIDsign and enterprise KYC. The KILT token pays for on-chain DID registration and other fees, is staked to collators that produce blocks, and carries governance rights.

In 2026 BOTLabs announced the evolution of KILT into Primer, extending the identity stack into AI-agent payments and trust management. On the enterprise side, a partnership with Deloitte applies the technology to credential verification, with use cases spanning KYC compliance, age verification, professional qualifications and academic diplomas. Supply-side figures show roughly 121 million KILT in circulation against a maximum of about 291 million, with allocation split among staking rewards, treasury and ecosystem grants.
