## Why Lock USDC on Yearn Finance?

Locking USD Coin (USDC) – a dollar-pegged stablecoin – in Yearn vaults offers unique advantages:

1. **Stability**: Avoid crypto volatility while earning yield
2. **Competitive APY**: Often outperforms traditional savings accounts (typically 3-8% APY)
3. **Hands-off compounding**: Automatic reinvestment boosts returns
4. **DeFi exposure**: Access institutional-grade strategies without expertise
5. **Liquidity**: Most vaults permit withdrawals without long lockups

## Step-by-Step Guide to Lock USDC on Yearn Finance

### Prerequisites:
– Web3 wallet (MetaMask, Coinbase Wallet)
– USDC tokens in your wallet
– ETH for gas fees (minimum $10-$50 recommended)

### Locking Process:
1. **Connect Wallet**: Go to [yearn.finance](https://yearn.finance/) and click “Connect Wallet” in the top-right corner. Authorize the connection.

2. **Navigate to Vaults**: Select the “Earn” tab, then choose “Vaults” from the dropdown menu.

3. **Select USDC Vault**: Scroll to the USDC vault (e.g., “USDC yVault”) and click “Deposit”.

4. **Approve Token Spending**: Confirm the token approval transaction in your wallet. This allows the vault to access your USDC (one-time action).

5. **Deposit Funds**: Enter the USDC amount to lock, review estimated APY, and click “Deposit”. Verify gas fees before confirming.

6. **Monitor Position**: Track earnings in the “Portfolio” section. Withdraw anytime via the vault’s “Withdraw” button.
