Sumsub, a digital identity verification provider, has introduced a reusable identity credential solution built on the Solana blockchain, signaling a significant shift in how users manage online verification in Web3 environments. The announcement took place during a live demonstration at the Solana Accelerate event held in New York, marking the first practical deployment of Sumsub’s identity system within a decentralized setting.
The new solution utilizes the Solana Attestation Service, an open-source protocol developed to link verified off-chain information with on-chain wallet addresses. Through this integration, users can generate a Sumsub ID, complete a one-time Know Your Customer (KYC) verification, and receive a blockchain-based attestation connected to their self-custodied Solana wallet. Once verified, these credentials can be used across supported decentralized applications (dApps), eliminating the need for repeated identity checks.
This approach differs from traditional verification processes by not storing any personal data directly on-chain. Instead, it confirms the authenticity of a user’s verification by indicating they have been validated by a trusted provider, ensuring compliance with regulations while safeguarding user privacy.
A real-time use case of this technology was demonstrated with Roam, a virtual SIM card provider. Users were able to complete the KYC process through Sumsub, link their wallets, and immediately access Roam’s services using their newly issued digital identity. This case showcased the practical application and efficiency of Sumsub’s system in reducing onboarding friction.
The rollout builds upon Sumsub’s Reusable Digital Identity framework, which was initially launched in March 2025. This suite was developed to simplify compliance and onboarding procedures across a broad range of digital platforms by enabling users to reuse a single verified identity. The aim is to eliminate repetitive documentation steps and significantly reduce verification times across multiple services.
Sumsub’s initiative aligns with a growing trend in the Web3 sector favoring decentralized identity frameworks. These models emphasize user ownership and control, allowing individuals to manage their identity credentials through blockchain wallets and decentralized identifiers rather than relying on centralized databases.
As digital identity becomes a foundational component for blockchain-integrated services—including financial platforms, gaming ecosystems, and telecommunications—the adoption of reusable identity credentials is expected to gain traction. Sumsub’s integration with Solana not only sets a precedent for future identity standards in decentralized ecosystems but also addresses the dual challenges of privacy and compliance that frequently hinder widespread adoption.
This development positions Sumsub as a key player in shaping identity infrastructure for Web3, providing a scalable, user-friendly, and secure verification alternative that accommodates both regulatory requirements and user sovereignty. The company’s strategy reflects a broader movement within the blockchain industry to transition from fragmented verification systems to interoperable, privacy-focused identity solutions that can serve as essential infrastructure in the next generation of digital services.
