Sumsub has announced a new integration with Verax, the attestation protocol built on Consensys’ Ethereum Layer 2 network Linea, to deliver reusable, privacy-first identity credentials on-chain. The solution was unveiled during the EthCC event in Cannes and marks Sumsub’s second public rollout of its on-chain verification capabilities.
The integration allows Web3 users to create a Sumsub ID through Linea Hub, undergo a liveness check, and connect their MetaMask wallet for an AML background check. Once verified, users receive a gas-free on-chain attestation to their wallet address via Verax. The attestation is then recorded on Linea and visible through its public explorer, enabling verified users to access services or incentives across decentralized applications in the ecosystem.
Gasless attestations and Layer 2 scalability
Ilya Brovin, Chief Growth Officer at Sumsub, commented, “Our integration with Linea marks a powerful next step in our mission to bring reusable, privacy-first identity to every corner of Web3. As more ecosystems adopt on-chain credentials, we’re building the infrastructure needed for users to verify once and remove unnecessary repetition and friction, without compromising on high security standards. By combining gasless attestations with Layer 2 scalability, this rollout integration helps to ensure a more user-centric, secure, and interconnected Web3.”
The collaboration builds on Sumsub’s Reusable Digital Identity suite, which launched in March 2025 and debuted on-chain capabilities through Solana’s Attestation Service earlier this year. The product allows individuals to verify themselves once and reuse their identity credentials across multiple platforms, helping to streamline compliance while preserving user privacy.
Every user who completes an attestation on Linea receives twenty free transactions, with gas fees refunded according to offer terms. This incentivized onboarding is part of Linea’s broader strategy to support frictionless user journeys and strengthen ecosystem adoption.
Sumsub’s approach enables real-time proof of humanity and eligibility while maintaining decentralized principles. No document uploads are required unless mandated by specific applications, and credentials can be reused across dApps in the Linea network. The joint rollout reflects the growing interest in decentralized identity solutions that can enhance onboarding speed, interoperability, and user trust in Web3 environments.
Next Generation tapped Sumsub’s KYC for euro-backed stablecoin infrastructure
France-based fintech company Next Generation NGPES has chosen global verification provider Sumsub to deliver fraud protection, identity verification, and AML compliance for its soon-to-launch payment infrastructure, which includes a euro-backed stablecoin and a unified wallet integrating digital assets with traditional finance.
The Next Generation Payment Ecosystem (NGPES) combines digital asset custody, settlement, compliance, and IBAN-based payments into a single platform. As it prepares to enter the market, Next Generation will rely on Sumsub’s suite of verification tools, which include Liveness detection, transaction monitoring, and AI-powered fraud detection to support both security and regulatory obligations.
Sumsub’s systems are designed to go beyond traditional onboarding, offering full-cycle verification to catch fraud attempts after initial checks. The company reports that fraud in the cryptocurrency sector rose 48 percent in 2024, with only 29 percent of crypto firms currently meeting full Travel Rule compliance.
The partnership comes as Next Generation finalizes its entry into Europe’s digital finance space, with its regulated stablecoin playing a central role in its payments model. By using Sumsub’s infrastructure, the firm aims to meet evolving European regulatory standards while safeguarding users against increasingly complex fraud schemes.
