Defi App simplifies both processes for ease of use. ### Private Key A secret number used to access and manage your cryptocurrency. If someone else has your private key, they have control of your funds. ### Slippage The difference between the expected price of a trade and the actual price at which the trade is executed, often due to volatility or low liquidity. ### Solana A high-speed, low-cost blockchain supported by Defi App for cross-chain functionality alongside Ethereum-based networks. ### Stablecoin A type of cryptocurrency designed to maintain a stable value, usually pegged to a fiat currency like the USD. ### Swap Aggregation The concept of combining swap options from different decentralized exchanges to provide users with the best rates available. ### Wallet Aggregation The concept of managing multiple wallets from different blockchains within a single interface, simplifying the user experience. ### Yield Farming The process of earning rewards, typically in the form of tokens, by providing liquidity or staking assets in a DeFi protocol. *** #### **Need More Information?** If there's any term you're still unsure about, read through the documentation on that topic for more in-depth explanations, or contact our support team for additional help.
