Sumsub joined the idOS Consortium and became a member of the idOS Association Governance Committee through a strategic contribution, advancing reusable identity infrastructure for Web3. The move addresses a persistent compliance problem: users currently complete separate KYC checks across wallets, exchanges, on-ramps, and regulated Web3 applications. This creates friction for users and higher costs for businesses, while repeated identity verification remains a barrier to mainstream crypto adoption.
Sumsub Integrates Attestation Protocols Across Multiple Blockchains
Sumsub rolled out attestation integrations across Solana through the Solana Attestation Service, Linea through the Verax attestation protocol, and Chainlink's ACE Cross-Chain Identity framework. Ilya Brovin, Chief Growth Officer at Sumsub, said: "We've spent the past year proving that verified identity can travel with the user instead of being re-collected at every door, both off-chain and on-chain." The idOS Consortium membership adds to this strategy because idOS is provider-agnostic infrastructure designed to work with multiple verification providers rather than locking identity to a single compliance vendor.
idOS Provides Provider-Agnostic Identity Infrastructure
idOS is an identity infrastructure layer designed to integrate with different verification providers and support reusable credentials across multiple Web3 services. As a member of the idOS Consortium, Sumsub will contribute to the development of the project's open-source technology stack alongside other consortium members. Its governance role gives it a voice in how reusable identity rails evolve for regulated Web3 use cases. Lluis Bardet, Co-Founder of idOS, said: "Re-usable KYC isn't just an engineering problem – it lives at the intersection of cryptography, compliance, and privacy, and you only solve it by moving all three forward at once."
Reusable KYC Applies to Wallets, On-Ramps, and Tokenized Assets
Reusable identity allows users to verify once and reuse that verification across multiple services without every provider collecting the same personal data again. Use cases include crypto wallets, where users can access multiple regulated modules without repeating verification; fiat on-ramps, which reduces onboarding friction and conversion loss; banking modules, which supports embedded financial products inside wallets; tokenized securities, which helps enforce eligibility and transfer restrictions; DeFi lending, which allows compliant access controls without rebuilding identity from scratch; and cross-chain applications, which lets identity proofs travel across multiple networks.
Portable Identity Credentials Introduce Concentration Risks
Reusable KYC introduces risks related to data protection, credential abuse, and governance clarity. If many applications depend on the same identity infrastructure, outages, governance failures, or data security issues could affect a wide part of the ecosystem. Provider-agnostic and open-source approaches may reduce the risk that reusable identity becomes another closed compliance silo. Regulated firms need confidence that users have been properly verified, while users do not want their identity documents copied across dozens of platforms.
FAQ
What did Sumsub do with the idOS Consortium?
Sumsub joined the idOS Consortium and made a strategic contribution to become a member of the idOS Association Governance Committee, deepening its push into reusable identity infrastructure for Web3.
Why does reusable KYC matter for Web3 applications?
Reusable KYC addresses the problem of users being forced to complete separate identity checks across wallets, exchanges, on-ramps, and regulated Web3 applications. This creates friction for users and higher acquisition costs for businesses. Reusable identity allows users to verify once and reuse that verification across multiple services without repeated data collection.
What blockchains does Sumsub support for attestation integrations?
Sumsub rolled out attestation integrations across Solana through the Solana Attestation Service, Linea through the Verax attestation protocol, and Chainlink's ACE Cross-Chain Identity framework.
