Let's walk through an example of swapping 2000 USDC for crvUSD. After entering these details, the interface updates to show you a detailed quote for the trade:

Here’s what the detailed quote from the interface is telling us:

  • Exchange Rate: For every 1 USDC you swap, you will receive 1.00004 crvUSD. This rate already includes trading fees.
  • Trade Route: The Swap Router found the best price by routing your trade through two pools: first USDC → USDT, and then USDT → crvUSD.
  • Slippage Tolerance: This is a safety feature that protects you from large price swings while your transaction is being processed. The default of 0.03% means that in a worst-case scenario, the minimum you would receive is 0.99974 crvUSD per 1 USDC.

3. Approve and Swap

To complete the swap, you'll likely need to perform two separate transactions:

  1. Approve: Before swapping a token for the first time, you must grant the Curve smart contract permission to interact with it. This is a standard security step in DeFi. Click Approve and confirm the transaction in your wallet. You only need to do this once per token.
  2. Swap: Once the approval transaction is confirmed, the button will change to Swap. Click it and confirm the final transaction in your wallet to execute the trade.

4. Confirmation

After a few moments, the transaction will be confirmed on the blockchain. The interface will update to show your new crvUSD balance, confirming a successful swap:
