Skip to main contentBefore 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:
- Approve the vault contract to spend your tokens
- Deposit tokens into the vault for each currency you’ll trade
The vault system allows gas-efficient order management without repeated token approvals.
