# Credit Vault tutorial

Users can test Credit Vaults by creating their own demo vault on Optimism Sepolia using [this link](https://legacy.truefi.io/structured-credit-portfolio/create). 

{% hint style="warning" %}
Before beginning, you will need to switch to the Optimism Sepolia test network and ensure your wallet is funded with test ETH and test USDC assets.
