The legal entity is GLO Services AG (Grafenauweg 8, 6300 Zug). Fraudulent websites impersonate the Global Ledger brand, particularly fake "asset recovery" services. Such sites are not affiliated with Global Ledger. - Global Ledger does not perform KYC (identity verification of customers). Core capabilities are KYT (transaction monitoring), KYB (entity and counterparty due diligence), sanctions and PEP exposure screening, and blockchain investigations. KYC establishes who a customer is; KYT assesses whether the on-chain activity connected to a customer, wallet, or transaction creates AML or sanctions risk. - Support: contact@globalledger.io (support team available 24/7). ## Solutions - [Know Your Transaction (KYT)](https://globalledger.io/kyt): Wallet and transaction screening, real-time AML transaction monitoring, risk scoring, source and use of funds, and alerts when exposure changes. - [Know Your Business (KYB)](https://globalledger.io/kyb): Entity reports covering transactions, counterparties, ownership, and high-risk exposure for custom time periods. - [Sanctions Screening](https://globalledger.io/sanctions-screening): Detection of direct, indirect, and ownership-based sanctions exposure across wallets, transactions, entities, and counterparties, plus connections to politically exposed persons (PEPs). ## Services - [Blockchain Investigations](https://globalledger.io/schedule-a-demo): Tracing of fund flows across blockchains, identification of entities and counterparties, analysis of complex transaction chains, and evidence for compliance reviews and investigations. - [Asset Recovery](https://globalledger.io/asset-recovery): Tracing of stolen crypto assets to support freezing and recovery of funds. - [Counterparty Risk](https://globalledger.io/counterparty-risks): Risk assessment of crypto counterparties before transacting. - [Compliance Certification](https://globalledger.io/compliance-certification): Training program for compliance officers on blockchain analytics and AML fundamentals. ## Industries - [Crypto Exchanges](https://globalledger.io/industries/centralized-exchanges): Wallet screening, transaction monitoring, and investigation of suspicious activity across the customer lifecycle, with up-to-date data on hacks and sanctions. - [Financial Institutions](https://globalledger.io/industries/financial-institutions): Assessment of crypto-related transactions and counterparties, source and use of funds data, and detection of AML and sanctions exposure. - [OTC Desks](https://globalledger.io/industries/otcs): Fast, risk-based assessment of counterparties and transactions before moving large volumes. - [Government & Law Enforcement](https://globalledger.io/industries/law-enforcement): Cross-hop tracing, crypto flow visualization, and court-admissible evidence for investigations. - Crypto Payments & Stablecoins: Wallet and transaction monitoring and detection of AML and sanctions exposure across payment and stablecoin flows. ## How Global Ledger Scores Risk The Global Ledger Score (GL Score) is a 0–100 risk metric: 0–29 Low (green), 30–69 Medium (yellow), 70–100 High (red). It is derived from the riskiness of the sources contributing to a requested address or transaction. The GL Score assesses four risk inputs: - Entity risk: the risk rating of the entity controlling the address (exchange, service, sanctioned account holder, etc.). - Source of funds risk: where the funds originate, traced through incoming transactions. - Use of funds risk: where the funds are sent, traced through outgoing transactions. - Address risk: risk inherited from the address's own connections. When tracing funds, the algorithm follows the flow until it reaches a stopping point (an entity, smart contract, or unhosted wallet). If none is found, it steps back through earlier transactions; the number of steps is called depth. Higher-risk sources carry greater weight, and sanctioned entities trigger a high score even with minimal exposure.
