# FAQ ## What does the funding rate show? The funding rate displayed in the header bar shows you an estimate of the rate that will be assessed at the end of the payment epoch. ## What is a payment epoch? Payment epochs occur every 8 hours. This is the interval for funding rate payments, trade mining, and PnL settlements. ## What is a PnL Settlement? Every 8 hours, open positions are settled vs the mark price. ## What is trade mining? Trade mining is a form of liquidity mining that ensures active traders receive DDX so that they can participate in DerivaDAO governance (and receive reduced fees, when paying in DDX). Makers and takers receive proportional shares of a DDX allotment every payment epoch. | Amount per payment epoch | Makers | Takers | | ------------------------ | ------ | ------ | | 3196.34703196 DDX | 20% | 80% | --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
