Before you can place, cancel, or claim orders on the 1st DEX, you need to complete these one-time setup steps.

​
1. Obtain USDC

You need USDC (or other quote currency) in your wallet to:
  • Post maker orders (quote is locked when you MAKE)
  • Execute taker orders (quote is spent when you TAKE/SPEND)
Ensure you have sufficient USDC balance on the target network (Base Sepolia, etc.) before proceeding.

​
2. Obtain tokens to trade

Acquire the base tokens you want to trade:
  • For buying: you’ll receive base tokens when your quote orders fill
  • For selling: you need base tokens in your wallet to sell
The 1st DEX trades MirrorTokens representing real-world assets. Check the available markets on your target network.

3. Approve tokens & deposit to vaults

All trading happens from vault balances, not directly from your wallet. You must:
  1. Approve the vault contract to spend your tokens
  2. Deposit tokens into the vault for each currency you’ll trade
