### Definition

The sum of all MEV tips in native units and USD that interval. The MEV tip represents the non-native transaction fee that goes to miners or validators as an incentive mechanism for transaction ordering. MEV tips are excluded from total native fee metrics.

### Details

* This fee is not included in `FeeTotNtv`. Total fees paid for transactions (MEV + protocol fees) can be obtained by leveraging the following formula: $$TotalFees=FeeTotNtv+FeeMevTotNtv$$

### **Asset-Specific Details**

* For Solana, slots proposed by validators running the Jito-Solana client are considered as MEV slots. Further, in Solana it is possible to identify which transactions paid MEV tip in addition to simply identifying the slot. For this metric each individual transaction is evaluated to determine which are MEV-enabled and which aren't.
