**Viridus puts a shared portfolio to work in stock-token markets.**

Stock tokens are blockchain tokens linked to stocks. Traders need liquidity: assets available to buy and sell. Viridus supplies those assets and earns a fee when traders use them.

You deposit **USDG** and receive **vUSDG**, your share of the portfolio. A manager chooses where to provide liquidity. Trading fees, changing stock prices and costs all affect what your shares are worth.

This is an investment, not a fixed-interest savings account. Your shares can lose value, and getting your USDG back can take time.

The next five short pages explain returns, shares, withdrawals, fees and risk. Four brief references follow if you want more detail.
