How to Buy Stocks and Indices on Ostium (Arbitrum)

If you're looking for a simple way to trade real-world stocks and indices like Tesla (TSLA), Apple (AAPL), or the S&P 500 (US500) using crypto, Ostium on Arbitrum offers a powerful DeFi solution. Ostium is a decentralized platform where users can take long or short positions on tokenized versions of traditional financial assets — all without needing a brokerage account or going through KYC.

To get started, users need a crypto wallet like MetaMask connected to the Arbitrum network. After funding their wallet with ETH (for gas) and a stablecoin like USDC or DAI, users can head over to Ostium’s app to begin trading.

One of Ostium’s key features is the ability to use leverage when trading. Leverage allows traders to amplify their exposure:

• 1x leverage means you're trading only with your own funds. There’s no risk of liquidation.
• 10x leverage gives you 10 times more exposure, but a 10% loss will liquidate your position.
• 100x leverage is extremely high risk — even a 1% move against your position can wipe you out.

Ostium’s UI makes it easy to choose assets, select leverage, and execute trades. The platform offers around-the-clock access to markets, running entirely on-chain.

For beginners, it’s advised to start with 1x leverage to avoid liquidation risk and get comfortable with the system. As you gain experience, higher leverage can be used carefully to increase potential gains — but only with strong risk management.
