Secure Wallet Authentication — Your private keys never leave your wallet. You approve each transaction individually. Connect MetaMask (or any WalletConnect-compatible wallet) to test trading endpoints.
Important: Ensure you are on the correct network (Arbitrum One for Mainnet, Arbitrum Sepolia for Testnet). Start with small amounts on Testnet. Each order requires wallet approval.
