Identity verification provider Sumsub has officially launched its reusable digital identity solution on the Solana blockchain, allowing users to verify themselves once and carry their credentials across decentralised applications. The announcement was made during a live demonstration at the Solana Accelerate event in New York, marking the first real-world use of Sumsub ID in a Web3 environment.
The integration leverages the Solana Attestation Service, an open protocol designed to link verified off-chain data with on-chain wallet addresses. This allows users to create a Sumsub ID, undergo a one-time Know Your Customer check, and receive a blockchain-based attestation tied to their self-custodied Solana wallet. The credential can then be used across compatible decentralised applications without repeating the verification process.
Unlike traditional methods, these attestations do not publish personal data on the blockchain. Instead, they prove that the user has been verified by a trusted provider, balancing privacy protection with regulatory compliance.
The system was showcased through a real-time identity verification process with Roam, a virtual SIM card provider. Users completed KYC via Sumsub, connected their wallet, and instantly onboarded to Roam using their new digital credential.
The integration builds on Sumsub’s Reusable Digital Identity suite, first introduced in March 2025, which aims to streamline onboarding and compliance across digital platforms. By allowing users to reuse a single verified identity across multiple services, the platform cuts down on repeated document submissions and shortens onboarding times.
This move is part of a broader trend in the Web3 ecosystem toward decentralised identity solutions, where users retain control over their credentials through blockchain wallets and decentralised identifiers.
As identity verification becomes increasingly central to blockchain-based services, ranging from finance to gaming and telecommunications, solutions like Sumsub’s reusable ID are poised to become essential infrastructure.
