# Fees

## Exchange Fee Dominance

> \*\*Definition.\*\* Exchange Fee Dominance is the percentage of total transaction fees paid in transactions related to on-chain exchange activity, segmented by counterparty role:\n- Deposits: transactions that include an exchange address as the receiver of funds.\n- Withdrawals: transactions that include an exchange address as the sender of funds.\n- In-House: transactions that include addresses of a single exchange as both the sender and receiver of funds.\n- Inter-Exchange: transactions that include addresses of (distinct) exchanges as both the sender and receiver of funds.\n\n\*\*Technical.\*\* When a transaction can be categorized into multiple of these categories, for example a transaction that sends funds externally as well as in-house, the fees are split into percentages according to the volume transferred. Exchange metrics are based on Glassnode\&#x27;s continually updated set of labeled exchange addresses, together with statistical and data-science methods that are refined over time. The series is therefore mutable: its established history is stable, but recent data points may revise as labels update. For methodology and limitations, see our \[article on exchange metrics]\(<https://insights.glassnode.com/exchange-metrics/>) and \[Exchange Data Transparency Notice]\(<https://docs.glassnode.com/further-information/exchange-data-transparency-notice).\n\\>

## Fee Ratio Multiple (FRM)
