Robinhood Wallet, MetaMask, Rabby, or any browser wallet that announces itself on Robinhood Chain. You will be asked to sign one short message — it is free, sends no transaction, and is how the server knows the address is yours.
You’re about to play Petroleum Strategy on Robinhood Chain (chain 4663), an EVM L2 that settles on Ethereum with ETH as gas. Connect Robinhood Wallet, MetaMask, Rabby, or any browser wallet that announces itself. Wallet approvals and transactions must be confirmed in your own wallet. Mainnet transactions use real assets and cannot be reversed. PETRO is a game, not a financial product; rewards are not guaranteed.
