Introduction
Cross-chain bridging allows you to transfer assets between blockchains securely. This guide covers how to move tokens from Polygon to Ethereum Mainnet using Celer's cBridge, along with key concepts about both networks.
Step-by-Step Bridging Process
Step 1: Connect Your Wallet
- Click "Connect Wallet" on cBridge
- Ensure your wallet is set to Polygon network
Step 2: Select Networks and Token
- From: Polygon
- To: Ethereum Mainnet
- Choose token (USDT, USDC, MATIC, etc.)
Step 3: Enter Transfer Amount
- Input amount in "Send" field
- Estimated receive amount will display automatically
Step 4: Review and Confirm
- Verify transaction details
- Check gas fee estimates
- Click "Transfer" and approve in your wallet
Step 5: Completion
- Most transfers complete within seconds
- Some may take up to 20 minutes during high traffic
- Check "Transfer History" for details

What Is a Crypto Bridge?
Blockchain bridges connect separate networks to enable:
- Asset transfers
- Information sharing
- Interoperability between ecosystems
Bridge Types
- Liquidity-Based: Uses pooled assets on both chains
- Canonical-Based: Locks assets on source chain, mints representations on destination
- NFT Bridges: Support both pegged and multi-chain native NFTs
Benefits of Cross-Chain Bridging
Cost Efficiency
- Avoid high fees on congested networks
- Access cheaper alternatives
Expanded Opportunities
- Explore different DeFi protocols
- Access higher yield opportunities
- Diversify across ecosystems
