# How-to: Connect your wallet

> Connect an EVM-compatible wallet to the StableFX Console for signing and funding trades.

Connect an EVM-compatible wallet (such as MetaMask or a WalletConnect-supported
wallet) to the [StableFX Console](/stablefx/concepts/console-overview) for
signing trades and funding settlements onchain. The console uses
[Dynamic.xyz](https://www.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:

| Environment | Network     | Chain ID  | RPC URL                           |
| ----------- | ----------- | --------- | --------------------------------- |
| Testnet     | Arc Testnet | `5042002` | `https://rpc.testnet.arc.network` |

<Note>
  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:

<Steps>
  <Step title="Start a trade">
    Open the trade form and configure your trade (currencies, amount, and
    tenor—the settlement period for the trade). Click **Continue**.
  </Step>

  <Step title="Connect wallet">
    The **Select Wallet** panel appears. Click **Connect Wallet** to open the
    wallet selector.
  </Step>

  <Step title="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.
  </Step>

  <Step title="Approve the connection">
    In your wallet, approve the connection request from the StableFX Console.
  </Step>

  <Step title="Confirm your address">
    The console displays your connected wallet address. Verify it is correct and
    click **Continue** to proceed to trade confirmation.

  </Step>
</Steps>

## 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](https://github.com/Uniswap/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](/stablefx/howtos/grant-usdc-allowance-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

| Issue                            | Solution                                                                                                                                  |
| -------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------- |
| Wallet not appearing in selector | Ensure the browser extension is installed and unlocked, or refresh the page.                                                              |
| Wrong network                    | Switch your wallet to the Arc network (testnet or mainnet). The console may prompt you to switch automatically.                           |
| Insufficient balance             | Add tokens to your wallet. On testnet, use the [Circle Faucet](https://faucet.circle.com/) to obtain USDC and EURC.                       |
| Permit2 approval fails           | Ensure you have enough ETH (or the native Arc token) for gas fees. Try resetting your wallet's transaction history if the nonce is stale. |
| Signature rejected               | If you reject a signature in your wallet, the console displays an error. You can retry by clicking the sign button again.                 |

Once your wallet is connected and funded, you are ready to execute trades. For a
guided walkthrough of your first trade, see
