Getting Started

Verifi Wallet User Manual

Verifi Wallet is the first global standard for the secure deconfliction of cryptocurrency investigations. Built by an active federal special agent and a team of detectives, it’s designed to accelerate casework and combat financial crime—powered by a database of over 350 million wallet addresses and growing rapidly with new entries added daily.

Whether you’re a police officer, detective, special agent, investigative analyst, financial crime investigator, or part of an institutional team, this guide will help you get started with Verifi Wallet’s essential features. Verifi Wallet is purpose-built to support your investigations by streamlining intelligence gathering, improving decision-making, and cutting down redundant efforts across agencies.

Start with a Wallet Lookup: Check any wallet address to see if it’s been reported or flagged by law enforcement, financial institutions, or trusted industry sources. Get instant insights into the trustworthiness of a wallet before sending funds.
Explore Known Connections: View reported counterparties linked to the wallet address you searched. These links help trace fund flow and uncover deeper connections between wallets involved in risky or suspicious activity.
Understand Wallet Reputation: Each wallet profile includes trust indicators such as confirmed reports, known associations, alert flags, and contextual labels—such as ties to darknet marketplaces or other high-risk categories. These insights help you make informed decisions based on verified sources and open-source intelligence.
Contribute to the Network: If you’re with law enforcement, a regulatory body, or a verified partner, you can report wallet addresses of interest. Contributions help strengthen the shared database and protect the broader crypto community.
