How to Bridge CFX from Conflux Network to Binance Smart Chain

·

The ShuttleFlow 2.0 cross-chain protocol now enables seamless asset transfers between Conflux Network and Binance Smart Chain (BSC). This upgrade supports bidirectional interoperability, allowing users to move assets from Conflux to major public chains like Ethereum and BSC. By leveraging Conflux as a cross-chain hub, ShuttleFlow connects Ethereum and BSC networks, enabling permissionless asset transfers for projects and users alike.

In this guide, you’ll learn how to bridge CFX tokens from Conflux to BSC step by step.

Prerequisites: Setting Up Your Wallets

Before you begin, ensure you have both MetaMask and Conflux Portal installed and set up. These wallets are essential for managing assets on Binance Smart Chain and Conflux Network, respectively.

Once installed, log in to both wallets and ensure they are properly configured.

Configuring MetaMask for Binance Smart Chain

To interact with BSC, you need to configure MetaMask to connect to the Binance Smart Chain network. Here’s how:

  1. Open MetaMask and click on the network selection dropdown.
  2. Choose "Custom RPC" to add a new network.

  3. Enter the following details:

    • RPC URL: https://bsc-dataseed.binance.org/
    • Chain ID: 56
    • Currency Symbol: BNB
    • Block Explorer URL: https://bscscan.com
  4. Save the settings. MetaMask will now display "BSC MainNet" as the active network.

This configuration allows you to view and manage BSC-based assets directly in MetaMask.

Using ShuttleFlow for Cross-Chain Transfers

ShuttleFlow is a decentralized cross-chain protocol that facilitates asset transfers between Conflux and other networks. To get started:

  1. Visit the ShuttleFlow website and connect your Conflux Portal wallet.
  2. In the ShuttleFlow interface, select the cross-chain pair: BSC/Conflux.

Bridging CFX from Conflux to BSC (Cross-Out)

Follow these steps to transfer CFX from Conflux to BSC:

  1. Select Token:

    • In the "Cross-Out" section, choose CFX as the token to bridge. The "You will receive" field will automatically show bCFX (the BSC-pegged version of CFX).
    • Click the info icon next to bCFX for important notes: bCFX can be viewed in any BSC-supported wallet like MetaMask. If it doesn’t appear automatically, you may need to add it manually using its contract address.

  2. Enter Amount:

    • Specify the amount of CFX to bridge. The minimum cross-out amount is 100 CFX, with a fee of 0.5 CFX.
    • Note: A one-time address creation fee of 1.2 CFX applies for first-time users.
    • If the amount is below 100 CFX, the system will prompt you to increase it.

  3. Enter Recipient Address:

    • Copy your BSC address from MetaMask (not your Conflux address) and paste it into the "Cross-Out Wallet Address" field.

    • Click the info icon for reminders:

      • Always use a compatible BSC address to avoid irreversible loss of assets.
      • Transactions require block confirmations and may take time to process.
      • ShuttleFlow is decentralized and never accesses your private keys.
      • Assets are secured via audited smart contracts and multi-signature protocols.

  4. Confirm Transaction:

    • Click "Cross-Out" and confirm the transaction in your Conflux Portal wallet.
    • After confirmation, you can view the transaction status on ConfluxScan.

Viewing bCFX in MetaMask

After bridging, add bCFX to your MetaMask wallet to view your assets:

  1. In ShuttleFlow, copy the bCFX contract address from the token info popup.
  2. In MetaMask, click "Add Token" > "Custom Token".
  3. Paste the contract address. MetaMask will auto-detect the token details.
  4. Click "Add Token" to see your bCFX balance.

Bridging bCFX from BSC to Conflux (Cross-In)

To return assets to Conflux:

  1. Select Token:

    • In the "Cross-In" section, choose bCFX as the source token. The "You will receive" field will show CFX.
    • The minimum cross-in amount is 100 bCFX, with no fee (though BSC gas fees in BNB apply).

  2. Copy Deposit Address:

    • ShuttleFlow provides a unique deposit address for cross-in transactions.
    • Copy this address and use it in MetaMask to send bCFX.
    • Important: Never send non-bCFX assets to this address, as they may be irrecoverable.

  3. Execute Transaction:

    • Paste the deposit address in MetaMask, specify the amount, and confirm the transaction.
    • Wait for block confirmations. Once processed, the CFX tokens will appear in your Conflux wallet.

Frequently Asked Questions

Q1: Why can’t I see my bCFX tokens in MetaMask?
A: You may need to add bCFX manually using its contract address. Ensure MetaMask is connected to BSC MainNet, and use the "Add Token" feature to include bCFX in your asset list.

Q2: How do I transfer BNB to MetaMask for gas fees?
A: From Binance or another exchange, withdraw BNB to your MetaMask BSC address. Ensure you select the BEP-20 network (BSC) and use the correct address format.

Q3: What if I encounter an "invalid address" error?
A: This often occurs when using an incompatible address format. Double-check that you’re using a BSC-specific address (starting with "0x") and that your exchange supports BEP-20 withdrawals.

Q4: Is ShuttleFlow secure?
A: Yes. ShuttleFlow uses audited smart contracts and multi-signature security measures. Even if ShuttleFlow’s private keys are compromised, user assets remain protected.

Q5: Can I bridge tokens other than CFX?
A: ShuttleFlow supports multiple assets. Check the official website for the latest list of supported tokens and cross-chain pairs.

Q6: How long do cross-chain transfers take?
A: Transactions require block confirmations on both networks, typically taking 10–30 minutes. Delays can occur during network congestion.
