Gemini's sandbox site is separate from the Gemini Exchange and offers full exchange functionality using test funds, trades, and other features on the exchange. The prices and trade volume run independently from production and will not reflect market price. To access Gemini's sandbox, users need to register a new account at https://exchange.sandbox.gemini.com/. Your account should automatically be verified and provided with funds to execute test trades.
If you have any issues, please contact trading@gemini.com for assistance.
Please note Sandbox is used to test upgrades for the production server, and some services may not be available at all times.
