How Multi-Collateral Will Work
Unified Account Value
Your Trading Account will calculate total value across all deposited collateral types. Each asset will have a collateral weight based on its liquidity and volatility. Example collateral weights (hypothetical):- USDC: 100%
- APT: 95%
- BTC: 95%
- ETH: 95%
Auto-Conversion on Liquidation
If you’re liquidated while holding non-USDC collateral, the system will convert assets to cover losses. Conversion uses oracle prices with a small buffer for slippage.No Manual Conversion Required
You won’t need to swap assets to USDC before depositing. Deposit APT directly and start trading.Benefits
Capital Efficiency
Traders holding APT or BTC won’t need to sell their holdings to trade perps. Deposit your assets directly and maintain exposure while trading.Reduced Friction
No need to find the best USDC on-ramp. If you already have APT from staking or BTC from another chain, use it directly.Ecosystem Integration
Multi-collateral opens integrations with Aptos DeFi. LP tokens, staking derivatives, and other yield-bearing assets could eventually serve as collateral.Timeline
Multi-collateral support is scheduled after mainnet launch. Check the roadmap for current status.When multi-collateral launches, existing USDC-only accounts will continue working. You can add other collateral types at any time.
