# afrxETH Vaults

**What is afrxETH**

afrxETH simply represents the compounding frxETH-ETH LP in the Concentrator vault. The total amount of frxETH-ETH LP contained in the Concentrator vault is equal to the total frxETH-ETH balance multiplied by the current index:

frxETH-ETH\_Balance = afrxETH\_Balance \* Current\_afrxETH\_Index

Using afrxETH to represent a share of the underlying compounding frxETH-ETH LP vault simplifies the smart contracts and is more gas efficient.

**Is it safe?**\
The concentrator is built by the experienced and security-obsessed AladdinDAO team, and it is audited by SECBIT Labs. Check out the audit here.

**How much does it cost?**

Concentrator takes a 10% treasury fee and a 2% harvest fee on yields. The fees were collected during the harvest process and distributed to the Treasury and Keeper respectively.
