BNB Attestation Service BASPrice $ 0.0131

BAS (BNB Attestation Service) is a blockchain-based infrastructure on the BNB ecosystem designed to create, manage, and verify attestations—trusted assertions or claims about data or identities. Users can define customizable schemas, generate attestations (both on-chain or in BNB Greenfield), and enforce ownership and privacy through flexible access controls. On-chain attestations are publicly accessible and immutable, while off-chain attestations stored in Greenfield maintain user ownership and can be permission-controlled or revoked as needed.

BASCan serves as the user interface and explorer for BAS, enabling both technical and non-technical users to browse schemas, make attestations, inspect records, and revoke them—all without coding knowledge.

The protocol supports advanced features such as resolvers for validation logic, GraphQL APIs, and SDK tools to power deeper developer integrations.
