The Crucial Role of Private Keys
While the Orca platform is secured by robust audits, the ultimate security responsibility rests with the user's wallet. Your wallet, whether a browser extension or a mobile app, holds the **seed phrase**—the master key to all your **SOL** and **SPL tokens**. Orca, as a DEX, never holds these keys; it only uses your signature to authorize transactions on the Solana blockchain. Protecting your seed phrase from phishing and securing your device from malware are the fundamental, non-negotiable layers of safety.
Wallet Security Across DeFi Activities
1. Spot Trading and Token Approvals
When executing a **Spot** trade on Orca, you authorize a one-time transfer of tokens. A common security risk here is the concept of **setAuthority** transactions, often requested by malicious dApps to gain permanent spending approval over your tokens. Always inspect the transaction details in your wallet; a safe swap on Orca should ask for a simple transfer, not delegate permanent authority. Regularly check and **revoke unnecessary token approvals** using a Solana approval tool.
2. Lending Protocol Connections
Interacting with **Lending** protocols involves long-term deposits and borrows. This means your wallet is constantly interacting with the protocol's contracts. The primary defense here is ensuring you only connect your wallet to the *official* domain of the lending platform. Phishing sites often mimic these interfaces to capture your interaction, attempting to trick you into signing a malicious transaction that drains your collateral or loan assets.
3. High Stakes: Perps and Hardware Wallets
Given that **Perps** (Perpetual Futures) trading often involves large sums or high leverage, this unit requires the highest level of security. We strongly recommend using a **hardware wallet** (like a Ledger or Trezor) for all Perps activities. This ensures the private key never leaves the physical device. While convenient, hot wallets (browser extensions) are more vulnerable to computer exploits; they should only be used for small amounts of SOL for gas fees.
4. Verifying Transactions via Simulation
Modern Solana wallets (e.g., Phantom) often offer **transaction simulation** before you sign, showing the predicted balance changes. This feature is your last line of defense. If you initiate a **Spot** swap for $100$ USDC and the simulation shows a much larger SOL deduction or transfer of an unrelated token, **do not sign**. This simulation step is invaluable for catching sophisticated exploit attempts across all DeFi interactions, including **Lending** and **Perps** collateral movements.
Essential Security Resources & Tools
Conclusion: You Are Your Own Security
The security chain for Orca is only as strong as its weakest link: the user's wallet. By safeguarding your seed phrase, always verifying the official website URLs before engaging in **Lending** or **Perps** activities, and critically reviewing every **Spot** transaction signature, you drastically reduce your exposure to risk. Adopt a "least privilege" mindset by regularly revoking unnecessary token approvals and committing to hardware wallets for significant capital.
Self-custody means self-responsibility; vigilance is your most powerful defense.
