Global verification provider Sumsub has joined forces with the BNB Attestation Service (BAS) on Binance’s BNB Chain. The collaboration will enable users to turn verified Web2 credentials into reusable on-chain attestations for accessing Web3 applications.
The integration marks the first use of Sumsub ID to issue on-chain credentials within the BNB ecosystem. According to the announcement, the system enables users to complete a one-time identity verification and then securely reuse those credentials across multiple decentralised applications (dApps).
Sumsub ID, which is part of the company’s Reusable Digital Identity product suite launched in March 2025, allows users to store their verified documents for multiple uses across participating platforms. Once verified, users receive tamper-proof digital proofs, or attestations, linked to their BNB wallets. This provides dApps, exchanges, and other protocols with confidence in the user’s verified identity.
Bridging Web2 trust models with Web3
The partnership aims to establish a stronger foundation for the Web3 ecosystem by bridging traditional Web2 trust models with on-chain reputation systems. As a core attestation issuer for BAS, Sumsub will facilitate faster onboarding for users by leveraging their verified Web2 identities. The companies also state the collaboration will reinforce compliance standards and help mitigate sybil risks, where a single user controls multiple wallets to manipulate participation or rewards.
“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.”
Reusable identity for Web3 use cases
The concept of a reusable digital identity is designed to reduce friction for both users and businesses. According to Sumsub, its solution can reduce onboarding time by up to 50 per cent and increase conversion rates by 30 per cent.
“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.”
Looking ahead, Sumsub and BAS plan to extend the benefits of this partnership to a wider range of Web3 applications. Potential use cases include streamlined KYC processes for exchanges and wallets, compliant access to DeFi protocols, connecting Real World Asset (RWA) platforms with identity credentials, and ensuring fair distribution for community airdrops by verifying real users.
