Bridge BNB to Polygon — Transfer BNB Across Chains
BNB is the native token of BNB Chain and can be bridged to Polygon to access a broader DeFi ecosystem. This guide explains how to move BNB cross-chain safely and at low cost.
Why Bridge BNB to Polygon?
BNB Chain is known for its high speed and low transaction fees, while Polygon excels in scalability and Ethereum compatibility. Bridging BNB to Polygon allows you to leverage Polygon's expanding DeFi ecosystem — including lending protocols, DEXes, and yield farming platforms — while starting from the BNB Chain.
Cross-chain bridges work by locking your BNB on the source chain and minting a wrapped equivalent on the destination chain. The process is reversible, meaning you can bridge back at any time.
Cross-chain transfers usually complete in under a minute, with fees typically under $1 — making it cost-effective even for small amounts.
How to Bridge BNB to Polygon
Connect your MetaMask or Trust Wallet to a supported bridge. Set BNB Chain as the source and Polygon as the destination. Select BNB as the asset, enter the amount, and confirm the transaction. Most transfers finalize within one to three minutes.
Key Tips
Ensure you keep a small amount of BNB in your wallet to pay for gas fees on the BNB Chain. When you arrive on Polygon, you will need a small amount of POL (MATIC) to pay for transactions on that network. Some bridges offer a gas top-up feature to help with this.
Check bridging fees before confirming. Most reputable bridges charge between 0.2% and 0.5% of the transferred value, making them significantly cheaper than centralized exchange withdrawals.
