Solidus Labs

Solidus Labs is a crypto-native market-integrity and compliance technology company founded in 2018 by former Goldman Sachs engineers, headquartered in New York with offices in Tel Aviv and London. Its HALO platform is a unified compliance control hub spanning eight modules — Trade Surveillance, Transaction Monitoring, Stablecoin Monitoring, Token Monitoring, Execution Quality, Case Management, Agentic-AI Workflows and Professional Services — used by regulated exchanges, broker-dealers, market makers, custodians, OTC desks, stablecoin issuers and regulators across digital assets, derivatives, equities and fixed income. The publicly documented developer surface is the TokenSniffer API, the programmatic face of Solidus Labs' Token Monitoring module: a key-authenticated REST API over smart-contract scam detection, the TokenSniffer "Smell Test" risk score, malicious token/pair/address feeds across 15+ chains, and a v3 webhook subscription API for real-time scam and rug-pull notifications. The HALO platform itself is delivered to contracted customers through regional dashboards and is not publicly documented.

Solidus Labs publishes 7 APIs on the APIs.io network, including Address API API, Chain API API, Corrections API, and 4 more. Tagged areas include Company, Compliance, RegTech, Trade Surveillance, and Market Integrity.

The Solidus Labs catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Solidus Labs’ developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 28 more developer resources.
