List of Decentralised Identity companies in Web3 (2026)

shdwDrive helps you store and access files securely by using blockchain technology, ensuring privacy and availability without relying on central servers.

VAAS implements document verification through Hedera Hashgraph technology, enabling authentication of digital information while maintaining data confidentiality and privacy.

V-Board implements secure customer onboarding through real-time video verification, enabling identity verification, document processing, and regulatory compliance across multiple industries.

idOS is a decentralized identity and data storage network that lets users verify once and access multiple stablecoin applications across blockchains. It offers self-custodial encrypted data, biometric sign-in, and KYC orchestration for compliant onboarding.

Naming service for degen chain.

Self is a zero-knowledge digital identity protocol and mobile app that lets users verify government IDs and disclose selected attributes like age or proof of humanity while keeping personal data on device. It enables privacy-preserving verification for Web2 and Web3 applications.

Web3 Domain Registration provides blockchain-based domain names through Unstoppable Name Service (UNS) and Crypto Name Service (CNS) smart contracts, enabling cryptocurrency address replacement and decentralized website hosting. The system operates on Polygon and Ethereum networks with permanent ownership and zero renewal fees.

Unstoppable Login implements OpenID Connect authentication using Web3 domains as identifiers, enabling users to access applications with their domain names instead of wallet addresses. The system provides decentralized identity verification with optional off-chain data sharing permissions.

A decentralized identity verification protocol on Solana that enables users to prove their humanity through privacy-preserving cryptographic methods without disclosing personal information. The system provides anti-bot protection for applications while maintaining user anonymity through zero-knowledge proofs and secure verification mechanisms.

tiny.place is an AI agent platform providing identity, discovery, encrypted messaging, and on-chain commerce infrastructure for autonomous agents. Agents register human-readable handle identities anchored to cryptographic keypairs, publish capabilities to a public directory, and communicate over end-to-end encrypted peer-to-peer channels. The platform settles payments between agents on a public blockchain, with escrow, a marketplace, bounties, reputation scoring, and games layered on top of these core primitives. Its server operates as a centralized relay that coordinates delivery and settlement without accessing message contents or holding private keys.

OfflineID is a universal decentralized identity system that connects devices, wallets, and social ties into a single, censorship-resistant profile. The system enables users to maintain portable social profiles that function without internet connectivity through privacy-first, encrypted peer-to-peer interactions and offline discovery capabilities.

ZKPassport Mobile App implements NFC-based identity document scanning and local zero-knowledge proof generation, enabling users to verify identity attributes from passports, ID cards, and residence permits without revealing personal data. The application processes all identity information locally on the device to ensure complete privacy.

Alastria ID is an open-source digital identity framework based on W3C Verifiable Credentials standards, enabling self-sovereign identity management with GDPR compliance for individuals and organizations across blockchain networks.

SureCircle Identity Assurance is a cryptographic identity verification service for organizations facing AI impersonation risks. Credential holders verify themselves by signing a one-click identity challenge with their unique cryptographic key, producing audit-ready proof of identity in under 20 seconds. The service addresses executive deepfakes, vishing, and business email compromise by using provenance-based credentials that cannot be replicated by AI.

Verified Web is a content authorization platform for public figures and organizations. Credential holders issue digital signatures on the content they publish across social media, news platforms, and hosted files. Audiences verify authenticity through a searchable public registry, inline browser extension badges, or a bio link pointing to the credential holder's verified profile. The platform is designed for bulk credentialing of rosters managed by talent agencies, PR firms, sports leagues, and management companies.

Proof of Intent is a blockchain-based authentication service that verifies whether a digital action was authorized by a human or initiated by an autonomous AI agent at the point of signing. The system uses idle smartphone capacity as a distributed witness network to validate transactions on a permissioned ledger. Telecom operators and enterprises use the service to detect AI-initiated transactions and fund customer loyalty programs from the economic value generated by network activity.
