Connect an EVM-compatible wallet (such as MetaMask or a WalletConnect-supported wallet) to the StableFX Console for signing trades and funding settlements onchain. The console uses Dynamic.xyz for wallet connection and supports any wallet that can sign EIP-712 typed data.

​
Prerequisites

Before you begin:
  • You have a Circle account with StableFX access. Contact your Circle representative if you do not have one.
  • You have an EVM-compatible wallet (such as MetaMask or any WalletConnect-supported wallet).
  • You have the wallet browser extension installed and unlocked, or a mobile wallet with WalletConnect support.

​
Supported wallets

The console supports wallets that are compatible with the EVM and can sign EIP-712 typed data (a standard for structured, human-readable signing requests used by DeFi applications). Common options include:
  • MetaMask (browser extension or mobile)
  • WalletConnect-compatible wallets (Rainbow, Trust Wallet, Coinbase Wallet, etc.)
  • Hardware wallets connected through MetaMask (Ledger, Trezor)

​
Network requirements

Your wallet must be configured for the correct network:
If your wallet does not have the Arc network configured, the console may prompt you to add it automatically. Alternatively, you can add it manually in your wallet’s network settings.

​
Connect during a trade flow

The most common way to connect your wallet is during the trade flow:
1

Start a trade

Open the trade form and configure your trade (currencies, amount, and tenor—the settlement period for the trade). Click Continue.
2

Connect wallet

The Select Wallet panel appears. Click Connect Wallet to open the wallet selector.
3

Choose your wallet

Select your wallet provider from the list. If using a browser extension like MetaMask, the extension popup appears. If using WalletConnect, scan the QR code with your mobile wallet.
4

Approve the connection

In your wallet, approve the connection request from the StableFX Console.
5

Confirm your address

The console displays your connected wallet address. Verify it is correct and click Continue to proceed to trade confirmation.

Token requirements

Before you can sign and fund trades, your wallet needs:

​
Sufficient token balance

Your wallet must hold enough tokens to cover:
  • The trade amount (the currency you are selling)
  • The collateral (risk buffer), if applicable
The console checks your balance before allowing you to proceed.

​
Permit2 approval

StableFX uses the Permit2 contract for gas-efficient token transfers. You must approve the Permit2 contract to spend your tokens.
  • First-time setup: The console detects if you have not approved Permit2 and prompts you to do so during the trade flow. Your wallet displays a standard ERC-20 approval transaction.
  • One-time per token: You only need to approve Permit2 once per token. After approval, all subsequent trades use Permit2 signatures (no additional onchain approval transactions).
  • Manual approval: You can also approve Permit2 ahead of time. See Grant USDC allowance to Permit2.
The Permit2 contract address is 0x000000000022D473030F116dDEE9F6B43aC78BA3.

​
Wallet persistence

Your wallet connection persists across page loads in the same browser session. If you close the browser or clear cookies, you will need to reconnect. The wallet address used for a trade is recorded as the signer address in the trade details. You must use the same wallet to fund the trade.

Troubleshooting

Once your wallet is connected and funded, you are ready to execute trades. For a guided walkthrough of your first trade, see Execute your first trade in the console. For the full taker trade creation flow, see Create a trade in the console.
