What Is Crypto Open Interest?
Open interest is one of the most important metrics for understanding derivatives market activity. It shows the total value of outstanding derivative contracts that have not been settled, giving traders insight into market participation and leverage.
Read the guideWhat Is a Crypto Funding Rate?
Funding rates are periodic payments exchanged between long and short traders in perpetual futures markets. They keep the perpetual contract price anchored to the spot price and reveal the cost of holding leveraged positions.
Read the guideWhat Is Trading Volume in Crypto?
Trading volume is the total value of trades executed over a given period. It is one of the most fundamental metrics for assessing market activity, liquidity, and interest in a particular asset or protocol.
Read the guideWhat Is Total Value Locked (TVL) in DeFi?

Read the guideWhat Are Perpetual Futures in Crypto?
Perpetual futures are derivative contracts that let traders speculate on an asset's price without owning the underlying token. Unlike traditional futures, they have no expiration date and use funding rates to stay anchored to the spot price.

Revenue is the share of those fees that actually accrues to the protocol, its treasury or its token holders. The two are often confused, but the distinction is central to evaluating any crypto protocol.
