Navigating blockchain interactions without a computer can seem daunting, but with the right tools, you can seamlessly complete tasks like trading and minting NFTs on Starknet’s mainnet using just your phone. This guide walks you through the process step-by-step, leveraging OKX Web3 Wallet and a mobile browser for efficiency.
