What is BNB Attestation Service (BAS)?

BNB Attestation Service (BAS) is a modular, verifiable identity and reputation layer built for BNB Chain and beyond. It functions as the native verification and reputation layer on BNB Smart Chain, delivering composable Know Your Customer (KYC) tools and trust infrastructure for decentralized applications. The project positions trust as a programmable primitive, enabling privacy-preserving on-chain and off-chain verification. BAS is deployed on BNB Smart Chain as a BEP20 token and also utilizes BNB Greenfield for storing attestations. The token has a fixed maximum supply of 10,000,000,000 BAS, with 2,500,000,000 BAS in circulation, representing 25% of total supply. The project launched on July 17, 2025, and is categorized under AI & Big Data, MVB, Binance Alpha, Identity, and Infrastructure tags.

How does BNB Attestation Service work?

BAS operates as a decentralized, modular identity and attestation protocol on BNB Chain. It comprises three core components. BNB Passport aggregates KYC from Binance and other exchanges, integrated with Space ID, serving as the user's master identity. The Attestation Registry provides structured, cryptographically secure attestations covering identity, assets, credentials, and behavior. The BAS Verify SDK offers plug-and-play modules for dApps to integrate permissioning, personalization, and compliance filters. Users can perform on-chain or off-chain verification, assert ownership of attestations by storing them in BNB Greenfield, manage their verifications, and control data sharing. The architecture supports privacy-preserving verification, making trust a programmable and composable primitive for developers and users across the BNB ecosystem.

What makes BNB Attestation Service unique and valuable?

BAS distinguishes itself as the native verification and reputation layer on BNB Smart Chain, providing essential infrastructure for composable KYC and trust. Its modular design allows dApps to integrate permissioning, personalization, and compliance filters through plug-and-play SDK modules. The integration of BNB Passport with Space ID and KYC aggregation from Binance and other exchanges creates a unified master identity for users. By leveraging BNB Greenfield for attestation storage, BAS enables users to maintain control over their data while supporting privacy-preserving verification. The project's focus on making trust programmable addresses a critical need in Web3 for identity and reputation infrastructure, positioning BAS as a foundational layer for applications requiring verifiable credentials and compliance tooling.

What is BNB Attestation Service used for?

The BAS token is deployed on Binance Smart Chain and functions within the BNB Attestation Service ecosystem. The protocol is used to manage verifications, control data sharing, and store attestations via BNB Greenfield. Users can assert ownership of attestations and perform on-chain or off-chain verification. dApps utilize the BAS Verify SDK to integrate permissioning, personalization, and compliance filters. BNB Passport serves as the user's master identity by aggregating KYC from Binance and other exchanges. The Attestation Registry provides structured, cryptographically secure attestations of identity, assets, credentials, and behavior. BAS enables composable KYC tools and trust infrastructure, supporting privacy-preserving verification across the BNB Chain ecosystem and beyond.

How Is the BNB Attestation Service ecosystem developing?

The BAS ecosystem is developing through key integrations and milestones. BNB Passport integrates with Space ID and aggregates KYC from Binance and other exchanges. The Attestation Registry and BAS Verify SDK provide core infrastructure for dApps. On May 29, 2026, the Agent Passport Launch introduced a verifiable identity solution as a development milestone. The project is categorized under Infrastructure on TokenTerminal with a market share of 0.1%. BAS is listed on multiple data platforms and trading venues, with 75 to 77 active markets reported across sources. The token is verified by the Coinpedia markets team and has a community badge claimable via CoinMarketCap. The project continues to build the trust layer for the next generation of Web3 applications on BNB Chain.

How to mine BNB Attestation Service?

BAS is a BEP20 token deployed on Binance Smart Chain and does not operate on a traditional proof-of-work mining model. There is no public information describing a mining mechanism for BAS. The token's supply model is transparent, with a fixed maximum supply of 10,000,000,000 BAS and total supply equal to the cap. Detailed public information on staking or yield mechanisms is currently limited. Users interested in acquiring BAS typically do so through centralized exchanges or decentralized swap products where the token is available. The project's focus is on identity and attestation infrastructure rather than mining-based issuance.

How to keep your BNB Attestation Service Coin safe?

To keep your BAS tokens safe, use a reputable wallet that supports BEP20 assets on Binance Smart Chain. Store your private keys and seed phrases securely offline, and never share them with anyone. Enable two-factor authentication on any exchange accounts you use. Verify contract addresses before interacting with any token or dApp, and use official sources such as the project website and verified explorers like bscscan.com for confirmation. Be cautious of phishing attempts and unsolicited messages. For long-term storage, consider hardware wallets that support BNB Smart Chain. Always double-check recipient addresses before sending tokens, and keep your wallet software updated to the latest version.
