# Margin Lending Margin Lending lets you trade with more than what you deposit. When you open a trade on Aqua, you can borrow up to 1x your balance from the platform — instantly, no application needed You keep 100% of your profits. In return, you pay a fixed interest rate on whatever you borrow, only while you're borrowing it. ## How It Works When a user initiates a trade, the platform calculates the available borrowing capacity based on the user's deposited margin. The user can choose to utilize platform capital to increase their purchasing power. Interest begins accruing only when platform funds are actually deployed into a live Hyperliquid position. ### How It Works When you're ready to place a trade, Aqua shows you two purchasing power options: what you can do with your own funds, and what you can do with lending enabled. You choose. 1\. Deposit USDC into your Aqua wallet 2\. Open the trading page and select your asset 3\. Enable Margin Lending to see your boosted purchasing power 4\. Place your trade — the platform funds are deployed automatically 5\. Interest starts the moment platform capital is used in your position 6\. Interest stops the moment you close that position *You only pay interest on the amount you actually borrow — not on your available credit limit. Previewing a trade does not trigger interest.* ### What Does It Cost? 15% APR — fixed rate, charged hourly on your borrowed balance. In real numbers: • Borrow 10,000 USDC for 7 days → 29 USDC in interest • Borrow 50,000 USDC for 7 days → 146 USDC in interest • Borrow 50,000 USDC for 30 days → 625 USDC in interest Interest is deducted weekly. It's also collected immediately if you close a position, withdraw, or close your account. *The 15% APR reflects the 24/7 nature of crypto markets and the risk of leveraged perpetual trading. Traditional stock margin typically costs 4–12% annually — but those markets close on weekends.* ### Supported Assets * BTC * ETH * HYPE * NVDA * GOLD * SILVER * And other whitelisted pairs ### A Few Things to Know * You can borrow up to 1x your deposited balance * All profits after interest are yours — no profit sharing * If your losses grow large enough, the platform may auto-reduce your position to protect its capital * You cannot withdraw funds while you have unpaid interest * Maximum capital per account: 50,000 USDC during --- # Agent Instructions This documentation is published with GitBook.
