Getting started

​
What you need

  • A wallet that supports Ethereum (MetaMask, Coinbase Wallet, WalletConnect-compatible wallets)
  • Stablecoins to swap or deposit (USDC, USDT, RLUSD, or EURC)
You do not need ETH for gas if you use gasless mode. The protocol handles gas costs through the swap spread.

​
Step 1: Connect your wallet

Go to blankfx.org and click Go to App in the top right. Select your wallet provider and approve the connection.

​
Step 2: Make a swap

  1. Select the token you want to sell (e.g. USDC)
  2. Select the token you want to receive (e.g. EURC)
  3. Enter the amount
  4. Review the quoted rate and output amount
  5. Click Swap
  6. Sign the transaction in your wallet
If this is your first swap with a given token, you’ll be asked to approve the token first. This is a one-time on-chain transaction. After that, swaps are gasless: you sign a message (free), and the protocol submits the transaction on your behalf.

​
Step 3: Earn yield (optional)

If you want to earn from FX trading activity:
  1. Go to the Earn page
  2. Pick a pool (e.g. USD Pool)
  3. Click Supply
  4. Choose your token and amount
  5. Confirm the deposit
You’ll receive pool tokens representing your share. Yield accrues automatically from trading fees. Withdraw anytime after a 5-minute cooldown.
