Privacy-Preserving KYC Solutions

Galxe Passport is a privacy-preserving digital identity product that stores KYC attestations, wallet verifications, and social proofs in user-controlled, ZK-encrypted form, allowing holders to selectively disclose credentials without re-exposing raw personal data. Passport V3, launched in May 2025, added a compliance-ready layer explicitly targeting institutional and regulated platforms, extending Galxe's identity infrastructure into regulated financial contexts. The ZK architecture means compliance checks can be satisfied without centralizing sensitive data, addressing a core tension in regulated Web3 use cases. By 2025, Passport had issued credentials to over 217 million verified holders across its supported chains.

BitOK is a dedicated KYC/AML compliance platform for cryptocurrency, screening wallet addresses and transaction hashes against databases of known illicit activity including darknet markets, ransomware operators, sanctioned entities, and terrorist financing networks. The platform assigns risk scores based on counterparty exposure, measuring what share of a wallet's historical flows touched flagged sources rather than evaluating individual transactions in isolation. BitOK serves both individual users verifying asset provenance and enterprise clients requiring automated AML screening at volume. Its product lineup spans a simple single-address check tool, an enterprise API-driven compliance suite called KYT Office, a Telegram bot for on-demand screening, and structured audit-quality reports designed for regulatory review and legal proceedings.

HAPI Protocol builds AML screening directly into DeFi smart contracts, enabling integrated protocols to automatically reject interactions from wallets flagged for involvement in hacks, theft, or money laundering. The registry draws from established blockchain analytics partners — Chainalysis and Crystal Blockchain — with data processed through HAPI's distributed oracle network and validated via a DAO governance process before entry. When a wallet is flagged following an exchange hack on Ethereum, integrated Solana protocols can block it without any manual action by their teams. HAPI ID extends identity functions by distinguishing genuine human users from Sybil attackers and bots, primarily to ensure airdrops, governance distributions, and liquidity mining rewards reach verified participants. The Scamfari platform adds community-sourced reporting on scams and phishing operations, with evidence-backed submissions going through a validation process before contributing to the shared threat database. Scamfari 2.0 expanded this into a multi-level system combining community reporting with AI-powered analysis to automate data collection and decision-making at scale.
