Global verification and anti-fraud provider Sumsub has announced a new partnership with the BNB Attestation Service (BAS) on Binance’s BNB Chain. The collaboration introduces the use of Sumsub ID within the BNB ecosystem, marking the first time the tool is being applied to issue on-chain credentials. The initiative allows users to complete identity verification once and reuse those credentials securely across a wide range of Web3 applications.
Sumsub ID, part of the company’s Reusable Digital Identity suite introduced in March 2025, enables individuals to pre-verify their information and store documents for future verifications across different platforms. After verification, users are issued on-chain attestations, which act as tamper-proof proofs linked directly to their BNB wallets. This system provides decentralized applications, protocols, and exchanges with stronger confidence that their users’ identities have been verified.
Faster Onboarding and Stronger Security
By acting as a core issuer of attestations for BAS, Sumsub will help simplify onboarding with verified Web2 identities. This not only accelerates user access but also strengthens compliance practices and reduces sybil risks. Such risks occur when a single individual operates multiple wallets to distort participation or rewards within an ecosystem. By combining Web2 trust models with Web3 reputation frameworks, the partnership aims to reinforce integrity across the BNB Chain and set a stronger base for long-term growth.
The team behind BAS indicated that this development is a significant step in expanding the attestation registry across BNB Chain. They highlighted that Sumsub’s involvement would make it possible to bring Web2-verified credentials into decentralized finance, real-world asset platforms, and community airdrop programs. The move was described as one that would accelerate user access while preserving the security and scalability of the broader Web3 landscape.

Enabling a User-Centric Web3
Leaders at Sumsub emphasized that the partnership represents a milestone in advancing reusable digital identity for mainstream Web3 applications. They explained that the approach lowers barriers for users seeking access to platforms, while simultaneously offering businesses a reliable and compliant process for scaling their ecosystems. The company’s growth leadership outlined a vision where identity moves alongside the user, rather than creating friction, and where credentials can travel securely across multiple platforms.
Sumsub’s technology is designed to improve both user experience and business outcomes. The company estimates that its system can cut onboarding times by as much as 50 percent and raise conversion rates by around 30 percent, enabling enterprises to reach compliance benchmarks more efficiently while making the process smoother for end users.
Looking Ahead to Wider Applications
The collaboration between Sumsub and BAS is expected to extend beyond the current launch phase. Future plans include supporting exchanges and wallets through streamlined Know Your Customer processes, ensuring compliant participation in DeFi platforms, connecting identity credentials with real-world asset ecosystems, and facilitating airdrops that can be distributed fairly to verified individuals.
Through this integration, Sumsub and BAS are aiming to create a foundation for a more open, trusted, and user-focused Web3 environment. The combination of reusable credentials and secure attestations seeks to balance ease of access with the high standards of compliance needed in an evolving digital economy.
