How the sandbox works

Connect a wallet and sign a Sign-In with Ethereum message for Robinhood Chain (chain 4663). One active squad per wallet, within a global squad cap; squads deployed through the API count toward the same cap and appear in the Arena.

Each squad gets a practice budget in paper ETH, converted to a dollar balance at the ETH price when you deploy. Squads run on scheduled market refreshes, and no real orders are placed.
