Funds are placed into lending protocols (e.g. Aave, Compound) that offer high interest. These platforms have proven to hold depositor funds safe even under extremely volatile market conditions. Traditional banks make most of their money through lending - but the Vault gives more of the yield back to you.

Funds are placed into trading protocols known as Automated Market Makers (e.g. Uniswap, Sushiswap) that enable traders to exchange their assets. This activity generates fees which go back to those who have provided the funds.

Many DeFi protocols (e.g. Curve, Balancer) offer additional financial incentives to use their platforms which can significantly increase yield. GRO claims these rewards, sells them for profit and compounds the gains for you.
