Sumsub Partners with Binance’s BNB Attestation Service to Streamline Web3 Identity Verification

Sumsub, Sumsub, a global verification and anti-fraud provider, today announced its partnership with the BNB Attestation Service (BAS) on Binance’s BNB Chain. The launch marks the first use of Sumsub ID to issue on-chain credentials within the BNB ecosystem, enabling users to pre-verify their identity once and securely reuse those credentials across multiple Web3 applications.

Sumsub ID – part of the company’s Reusable Digital Identity product suite, launched in March 2025 – allows users to pre-verify themselves once and securely store their documents for multiple verifications across participating platforms. Once verified, users receive on-chain attestations – tamper-proof digital proofs tied to their BNB wallets – giving dApps, exchanges, and protocols confidence in their users’ verified identity.

As a core attestation issuer for BAS, Sumsub will enable faster onboarding with verified Web2 identities. The partnership also reinforces compliance standards and mitigates sybil risks. Sybil risks occur when a single user controls many wallets, skewing participation or rewards in an ecosystem.. By bridging Web2 trust models with Web3 reputation systems, the partnership establishes a stronger foundation for ecosystem growth.

“This partnership marks an exciting, key step in expanding our attestation registry across the BNB Chain. Working with Sumsub allows us to bring trusted Web2 credentials directly into DeFi, RWA, and airdrop use cases,” said Annie Lee, Founder at BNB Attestation Service. “By enabling reusable verification credentials, we’re giving users faster access while ensuring a safe and scalable Web3 ecosystem.”

“This partnership is a crucial milestone in our wider strategy to bring reusable digital identity into mainstream Web3 use cases. For users, it means fewer barriers when accessing platforms; for businesses, it provides a reliable and compliant way to welcome more people into their ecosystem,” said Ilya Brovin, Chief Growth Officer at Sumsub. “We’re proud to be driving a longer-term shift where ‘identity’ moves with the user, not against them. By enabling credentials to be carried securely across platforms, we will continue to lay the groundwork for a more open, trusted, and user-centric Web3 environment.”

Sumsub ID allows individuals to pre-verify once and reuse their identity data across multiple services. It can reduce onboarding time by up to 50% and boost conversion rates by 30%, offering businesses a more efficient route to compliance while improving user experience.

Looking ahead, Sumsub and BAS will extend these benefits across exchanges and wallets through streamlined KYC, support compliant access in DeFi, connect Real World Assets (RWA) platforms with identity credentials, and facilitate community airdrops with fair distribution to real users.
