# Money Market Fund Vaults

## Summary

There are several different types of Money Market Fund Vaults on the OpenTrade Platform. Each has slight differences in how they work but they all use highly rated USD and EUR Money Market Funds as collateral, enabling users to earn the risk free rate of return on their stablecoins while maintaining maximum liquidity, safety, and stability.

## USD Money Market Fund Vault (V5)

The primary difference between the USD Money Market Vault and the Flexible Term USDC Vault is the version of the protocol they run on. The Flexible Term USDC Vault runs on Version 4 and the USD Money Market Vault runs on Version 5. 

Version 5 vaults provide more flexibility in the flow of funds, use simpler contracts which are easier to upgrade, and support for several different exchange rate methods in a single vault type.

## Franklin Templeton Benji MMF Vault (V5)

The primary difference between the USD Money Market Vault and the Franklin Templeton Benji MMF Vault is the latter exclusively uses Franklin Templeton's tokenised money market fund (BENJI) as the underlying collateral. As such, the yield and processing times can vary from the other money market fund vaults.
