KYC verified the person.
KYB verified the business.
KYT verified the transaction.
KYA verifies the agent.
As autonomous AI systems begin executing financial transactions without
continuous human input, the compliance stack has a new and unresolved
layer. Know Your Agent is that layer.
Know Your Agent · KYA
Autonomous AI systems are initiating trades, submitting compliance reports, and executing payments without real-time human authorization. KYA establishes identity, authorization scope, and accountability for non-human actors — the compliance framework that KYC was never designed to cover.
→ Know Your AgentKnow Your Business · KYB
KYB is the institutional counterpart to KYC: verifying the legal entity, beneficial ownership structure, and authorization chain for businesses rather than individuals. As AI agents act on behalf of businesses, KYB becomes the foundational layer below KYA.
→ Know Your BusinessDecentralized Identity · DID · LEI · vLEI
Decentralized identifiers (DIDs), Legal Entity Identifiers (LEIs), and verifiable LEIs (vLEIs) are the cryptographic infrastructure beneath compliant agent identity. GLEIF's vLEI framework and W3C DID standards provide the building blocks for machine-verifiable organizational credentials.

Authorization, delegation, and signing infrastructure for AI agents: OAuth 2.1, mTLS, IAM frameworks, and programmable credential scope. The technical layer that determines what an agent is permitted to do — and what it is not.
→ Agentic CredentialsEach layer in the verification stack emerged when a new class of financial actor demanded its own accountability framework. KYA is the next layer.
