## Legal Entity Identifiers

A Legal Entity Identifier (LEI) is a unique 20-character alphanumeric code that identifies distinct legal entities that engage in financial transactions. It is a global standard that allows regulators and market participants to track and identify parties to financial contracts, enhancing market transparency and risk monitoring.

In the derivatives market, the use of LEIs is mandatory for many transactions to ensure that regulators can accurately assess the systemic risk posed by any single entity. As the digital asset market matures, the adoption of LEIs is becoming increasingly important for integrating crypto firms into the global financial system.

It provides a standardized way to link on-chain activity to off-chain legal entities, which is crucial for cross-border regulatory compliance and risk management.
