Sumsub Partners With Chainlink to Power Cross-Chain Identity for On-Chain Compliance

Sumsub and Chainlink to Enable Privacy-Preserving KYC Credentials Across Ethereum, Arbitrum, Avalanche, Polygon, and Base

MIAMI, May 5, 2026 /PRNewswire/ -- Sumsub, a global verification and anti-fraud leader, today announced its partnership with Chainlink, the industry-standard oracle platform. This enables compliant, privacy-preserving identity verification across major blockchains, allowing clients to leverage Chainlink's Automated Compliance Engine (ACE). As digital asset markets move into a more regulated phase, the ability to verify users across blockchain ecosystems without compromising privacy is becoming critical infrastructure.

The partnership provides access to a Cross-Chain Identity (CCID) framework, a core component of Chainlink ACE, to unlock reusable, privacy-preserving identity credentials on-chain in a way that supports compliant access across blockchain ecosystems. This addresses key challenges in on-chain compliance, including enabling verification without exposing raw personal data, supporting reusable identity across multiple wallets, and allowing permissioned access for asset issuers and protocols to enforce eligibility rules.

Once a user completes Sumsub's KYC flow and proves wallet ownership by signing a message, Chainlink ACE issues a CCID – a reusable, privacy-preserving credential containing verified claims like "Age > 18." No raw personal data ever touches the chain. This mechanic allows a single verified identity to be linked across multiple wallets, eliminating the need for repeated KYC at every entry point.

The initial rollout supports Ethereum, Arbitrum, Avalanche, Polygon, and Base, and is designed for a global retail-oriented audience participating in ACE launch campaigns. This represents Phase 1 of the rollout, in which individual retail users complete Sumsub's KYC flow and receive a reusable ACE credential linked to their wallet.

"Digital asset markets need identity verification that can extend into compliant on-chain workflows without forcing users through repeated onboarding," said Ilya Brovin, Chief Growth Officer, Sumsub. "Through Chainlink ACE, Sumsub can extend its identity verification services into compliant institutional digital asset markets and help enable access to permissioned assets with less friction."

"We're excited to see Sumsub support Chainlink's Automated Compliance Engine to advance privacy-preserving identity and compliance infrastructure, enabling the Cross-Chain Identity (CCID) framework for our clients. This is the kind of scalable, privacy-preserving compliance infrastructure needed to unlock tokenized assets at institutional scale." — Ishan Vishnoi, VP of BCM Product & Business Ops, Chainlink Labs.

This launch marks the first phase of a broader roadmap. Phase 2 is scheduled to be released in the summer of 2026, transitioning to a model in which Asset Issuers act as the end users. Future phases may involve Sumsub enabling users to connect to authorize third-party access to underlying data via API. Together, these phases reflect a shared vision for identity infrastructure that scales alongside the compliant digital asset ecosystem.
