# Multi-Collateral

> Use multiple asset types as margin from a single account

Decibel is launching with USDC-only collateral. Multi-collateral support is coming soon, allowing you to use APT, wrapped BTC, ETH, and other assets as margin.

## Current State

Today, Decibel accepts only USDC as collateral:

* Deposit USDC to your Trading Account
* All positions are margined in USDC
* PnL settles in USDC
* Withdraw USDC when you close positions

## What's Coming

Multi-collateral will let you use multiple asset types as margin from a single Trading Account.

### Planned Collateral Types

| Asset             | Status     | Notes                       |
| ----------------- | ---------- | --------------------------- |
| USDC              | ✅ Live     | Primary stablecoin          |
| APT               | 🔜 Coming  | Native Aptos token          |
| Wrapped BTC       | 🔜 Coming  | LayerZero or similar bridge |
| Wrapped ETH       | 🔜 Coming  | LayerZero or similar bridge |
| Other stablecoins | 📋 Planned | USDT, etc.                  |
| RWAs              | 📋 Planned | Real-world asset tokens     |

## 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%

If you deposit \$10,000 worth of APT with a 95% weight, your effective collateral is \$9,500.

### 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-traders/overview#product-roadmap) for current status.

<Info>
  When multi-collateral launches, existing USDC-only accounts will continue working. You can add other collateral types at any time.
