To utilize the Render Network, you need RNDR tokens, which can be obtained on several cryptocurrency exchanges. Once you've secured RNDR tokens in your wallet, they can be used within the Render ecosystem.

If you possess idle GPUs, you can register as a "Node Operator" on the Render Network, where your GPU's power can be used to complete rendering tasks in return for RNDR tokens. You simply connect your GPUs to the Render Network and begin accepting jobs.

Conversely, if you're a "Creator" needing rendering work, you can submit your projects to the Render Network. The network assigns your job to an available Node Operator, and you pay for this service with RNDR tokens.

In each transaction, OTOY receives a small percentage of RNDR tokens as a fee for maintaining the network and enabling operations.

Remember, it's crucial to store your RNDR tokens in a supported wallet and always follow good security practices when dealing with cryptocurrencies.
