The Conflux Network continues to expand its interoperability across major blockchain ecosystems, and one of the most significant developments is the integration between Conflux and Binance Smart Chain (BSC) via the ShuttleFlow 2.0 cross-chain protocol. This upgrade enables seamless, bidirectional asset transfers—allowing users to bridge CFX tokens from the Conflux blockchain to BSC as bCFX, and vice versa.
This guide walks you through every step of the process, ensuring a smooth and secure experience while maintaining full control over your assets. Whether you're looking to access DeFi protocols on BSC or simply diversify your holdings, this cross-chain functionality opens new doors.
Understanding ShuttleFlow 2.0 and Cross-Chain Interoperability
ShuttleFlow 2.0 is a decentralized cross-chain bridging protocol designed to connect Conflux with leading blockchains like Ethereum and Binance Smart Chain. By using Conflux as a central hub, ShuttleFlow allows permissionless asset transfers between networks—meaning any project or user can initiate a cross-chain transaction without requiring approval.
Key features:
- Bidirectional transfers: Move assets freely between Conflux and BSC.
- Decentralized security: Assets are held in audited smart contracts protected by multi-signature governance.
- No private key access: ShuttleFlow never has access to user wallets—your funds remain under your control at all times.
This infrastructure empowers users to leverage CFX across multiple ecosystems, increasing utility and liquidity.

Step 1: Set Up Your Wallets
Before initiating any cross-chain transfer, you’ll need two compatible wallets:
- ConfluxPortal: For managing CFX on the Conflux Network.
- MetaMask: For interacting with Binance Smart Chain (BSC).
Install and Configure Wallets
- Download ConfluxPortal and MetaMask from their official sites.
- Create secure accounts and back up your seed phrases.
Switch ConfluxPortal to Tethys Mainnet
Ensure your ConfluxPortal is set to the Conflux Tethys network (mainnet), not the testnet.
Add Binance Smart Chain to MetaMask
In MetaMask:
- Go to Settings > Networks > Add Network.
Enter the following details for BSC Mainnet:
- Network Name: Binance Smart Chain Mainnet
- New RPC URL:
https://bsc-dataseed.binance.org/ - Chain ID:
56 - Currency Symbol: BNB
- Block Explorer URL:
https://bscscan.com
Once saved, switch MetaMask to the BSC network.
🔐 Tip: BSC uses the same address format as Ethereum. Your MetaMask address remains unchanged when switching chains.
Step 2: Connect to ShuttleFlow
Visit the official ShuttleFlow website and connect your ConfluxPortal wallet.
After connecting:
- Select the cross-chain pair: Conflux ↔ Binance Smart Chain
- Choose whether you’re bridging out (CFX → bCFX) or in (bCFX → CFX)
Step 3: Bridge CFX from Conflux to BSC (Cross-Out)
Now you’re ready to begin the cross-chain transfer.
1. Select Token and Amount
- Under “Cross Out,” choose CFX as the source token.
- The destination token will automatically display as bCFX (the BSC-pegged version of CFX).
- Enter the amount of CFX you wish to transfer.
⚠️ Minimum transfer: 100 CFX
Cross-out fee: 0.5 CFX
First-time address creation fee: 1.2 CFX (one-time only)
These fees are subject to change based on service provider policies.
2. Enter Destination Address
Paste your MetaMask BSC wallet address (starts with 0x) into the “Cross-Out Wallet Address” field.
❗ Important:
- Only send to a valid BSC-compatible wallet.
- Never use a Conflux address here—funds sent to incorrect addresses cannot be recovered.
- Transactions require multiple block confirmations before completion.
3. Confirm and Submit
Click “Cross Out,” review the transaction in ConfluxPortal, and confirm.
Once submitted, you’ll see “Transaction Sent.” Use the “View Details” option to track progress on ConfluxScan.

Step 4: View bCFX in MetaMask
After confirmation (usually within minutes), your bCFX tokens will arrive on BSC—but they won’t appear automatically in MetaMask unless added manually.
Add bCFX as a Custom Token
- Open MetaMask and click "Import Tokens"
- Switch to the BSC network
- Paste the bCFX contract address (available in ShuttleFlow’s info panel)
- Confirm and add the token
You should now see your bCFX balance reflected in MetaMask.
💡 Pro Tip: Keep a small amount of BNB in your MetaMask for paying future BSC transaction fees (gas). A single transfer typically costs around 0.0007 BNB.
Step 5: Bridge bCFX Back to CFX (Cross-In)
To return your tokens to the Conflux Network:
- In ShuttleFlow, switch to the Cross-In tab
- Select bCFX as the source token
- Destination will auto-convert to CFX
- Copy the provided Conflux deposit address
Send bCFX via MetaMask
- Open MetaMask
- Send the desired amount of bCFX to the copied address
- Confirm transaction (you’ll pay gas in BNB)
⚠️ Minimum cross-in: 100 bCFX
Cross-in fee: 0 CFX (but standard BNB gas applies on BSC)
Wait for sufficient block confirmations. Once processed, your CFX will appear in ConfluxPortal.
Frequently Asked Questions (FAQ)
Q: What is bCFX?
A: bCFX is a BEP-20 token on Binance Smart Chain that represents CFX 1:1. It allows CFX holders to participate in BSC-based DeFi applications like yield farming, staking, and decentralized exchanges.
Q: Is ShuttleFlow safe?
A: Yes. ShuttleFlow is a decentralized protocol—your private keys are never exposed. Funds are held in smart contracts audited by third parties and secured by multi-signature controls, preventing unauthorized access even if internal keys are compromised.
Q: Why isn’t my bCFX showing up in MetaMask?
A: You must manually add the bCFX token using its contract address. If already added, try resetting MetaMask’s token detection or re-importing the contract.
Q: Do I need BNB to bridge CFX to BSC?
A: Yes. While bridging from Conflux doesn’t require BNB, receiving and using bCFX on BSC does—since all BSC transactions require gas paid in BNB.
Q: Can I use other wallets besides MetaMask?
A: Absolutely. Any EVM-compatible wallet that supports BSC—such as Trust Wallet, Coinbase Wallet, or OKX Wallet—can receive and manage bCFX.
Q: Are there daily limits on cross-chain transfers?
A: There are no hard limits, but each transaction must meet minimum thresholds (e.g., 100 CFX). Very large transfers may take slightly longer due to consensus verification.
By leveraging ShuttleFlow 2.0, users gain unprecedented access to cross-chain opportunities—unlocking liquidity, expanding investment options, and enhancing participation in both Conflux and BSC ecosystems.
Whether you're exploring DeFi innovations or optimizing asset allocation, mastering cross-chain movement is essential in today’s multi-chain world.
