# How to Supply

<a href="https://app.gauntlet.xyz/vaults/gtusda?utm_source=website&#x26;utm_medium=vaultbook&#x26;utm_campaign=page1" class="button primary" data-icon="circle-right">Explore the Vault</a>

### **Supply**

Capital allocators supply USDC into the vault via the [Gauntlet App](https://app.gauntlet.xyz/vaults/gtusda) on Base, Arbitrum, Optimism, and Ethereum Mainnet.

### **Receive gtUSDa**

Suppliers receive gtUSDa, an ERC-20 token that is a claim on the supply amount plus earnings. Supply is reflected onchain within 6-12 hours.

### **Yield Optimization**

Our automated optimization engine, combined with our risk management platform, selects various cross-chain opportunities for the vault to execute. This includes Morpho vaults on Base, Ethereum Mainnet, Arbitrum, and Optimism. The strategy optimizes for available yields within the opportunity set, considers TVL levels, assesses impacts from the size of a given allocation, and generates sustainable real yield.

### **Incentives**

Morpho Rewards/incentives are regularly converted to USDC and redeployed to the strategy. Gauntlet USDC Rewards are regularly streamed by Sablier.

### **Withdrawal**

USDC withdrawal requests can be initiated at any time for gtUSDa. Transactions complete within 6-12 hours on average.
