Sumsub, a verification provider for the crypto industry, and Chainlink, a decentralized oracle network, announced a new partnership focused on on-chain compliance. The companies are working together to enable identity verification across multiple blockchains without revealing personal data.
The integration uses Chainlink’s Automated Compliance Engine. The Cross-Chain Identity system allows users to authenticate themselves once and reuse that status on different networks. This approach is designed to solve a common problem in crypto where users often repeat KYC checks on each platform.
A user completes verification through Sumsub and confirms ownership of the wallet. Chainlink then issues a reference with basic claims, such as age confirmation. No sensitive data is stored in the chain. This allows protocols to check eligibility without accessing personal data.
The initial rollout includes major networks including Ethereum, Arbitrum, Avalanche, Polygon and Base. It is intended for private users participating in early access campaigns. In the next phase, expected to take place in summer 2026, the focus will shift to asset issuers. Later updates may allow users to access their data via APIs.
