Violet

Violet (operated by DeFi Labs GmbH) is a blockchain-native compliance and identity infrastructure platform purpose-built for decentralized finance. Founded in 2022 and headquartered in Berlin, Germany, Violet provides privacy-preserving, reusable on-chain compliance credentials that enable DeFi protocols and dApps to meet regulatory requirements without compromising user privacy.

Core Products/Services

Violet offers four modular compliance infrastructure products:

• VioletID: The flagship product and most advanced compliance guarantee in DeFi. VioletID is a reusable on-chain compliance credential that maps wallet addresses to verified compliance statuses. It functions as both a proof of unique personhood and an AML-compliant identity credential. Protocols integrate VioletID via a one-line code addition.

• Full AML: A comprehensive anti-money laundering solution combining KYC/KYB verification, continuous sanctions screening (US, UK, UN, EU lists), Know Your Transaction (KYT) monitoring via blockchain analytics, geofencing, accredited investor checks, and multi-factor authentication.

• GeoFencing: An on-chain access control product that allows DeFi protocols to ring-fence specific countries or regions, restricting smart contract and function access to authorized geographic jurisdictions.

• Sybil Resistance: Built on VioletID's proof-of-unique-personhood mechanism, this product ensures a one-to-one binding between a verified real human identity and a wallet address, preventing sybil attacks across DeFi applications.

Key Strengths

Violet's architecture is built around privacy-by-design principles. All personally identifiable information (PII) is stored off-chain in encrypted storage and never written to the blockchain. On-chain, only a binary compliance signal is shared via Ethereum Access Tokens (EATs) — signed messages compliant with EIP-712 that pass trusted compliance data from Violet's off-chain system to the Violet Verifier Smart Contract on-chain.

Violet also maintains a VioletID Registry — an on-chain registry mapping wallet addresses to specific compliance statuses that can be queried by any integrating dApp without additional Violet interaction. The system supports Decentralized Identifiers (DIDs), Verifiable Credentials (VCs), and is designed to be highly modular, supporting customized compliance schemas including accredited investor status and credit scores.

Violet's compliance program was directly used as the backbone for Mauve's VASP (Virtual Asset Service Provider) registration approval, demonstrating its regulatory credibility.

Notable Clients/Projects

• Mauve: The first fully compliant decentralized exchange, built entirely on Violet's compliance infrastructure. Every Mauve user requires a VioletID to swap tokens or provide liquidity.
• Humanbound: A protocol for securing interactions with human identities while protecting privacy, built using Violet's identity framework.
