Bridging tokens across different blockchain networks has become increasingly important in the world of DeFi. One particularly compelling bridge route is from BNB Chain (formerly BSC) to Polygon (MATIC). This bridge offers a myriad of benefits, enabling seamless interoperability and unlocking new possibilities for token holders and developers alike.
The first and most significant advantage of bridging a token from BNB to Polygon is access to a wider range of DeFi opportunities. While BNB has established itself as a thriving ecosystem with its own set of projects and applications, Polygon boasts a rapidly growing network of dApps and protocols. By bridging a token to Polygon, users can tap into this expanding DeFi landscape, exploring innovative platforms for lending, borrowing, yield farming, and more.
Furthermore, bridging to Polygon enhances scalability and transaction speed. BNB, like many other blockchain networks, faces limitations in terms of network congestion and high gas fees during peak usage periods. Conversely, Polygon employs a Layer 2 scaling solution that significantly improves transaction throughput and reduces costs. By migrating tokens from BNB to Polygon, users can enjoy faster and more cost-effective transactions, enhancing the overall user experience.
How to Bridge from BSC to Polygon in 3 Steps?
Step 1 - Connect Your Wallet
Go to ChainPort's bridge (https://app.chainport.io/) and connect your wallet. Ledger, Trezor, Coinbase Wallet, Wallet Connect, and Metamask are all supported by ChainPort. Select the wallet containing the tokens you wish to bridge.
Step 2 - Select the Chains & Token
You can select a source chain and a target blockchain from the drop-down menu. In our case, the source chain is BNB, and the target chain is Polygon. Next, select the token you’d like to bridge from the dropdown menu. If you want to bridge a token that is not on the list, you may paste its contract address. Please note that a token may not have liquidity on the target blockchain if it is not listed.
Step 3 - Confirm Tx & Get Tokens
Review all the related information before confirming the transaction. Details include the sending and recipient wallet, gas fees, and the token. Once all details have been confirmed, please approve the transaction and wait a few minutes for it to be processed. Once complete, your tokens have been successfully bridged to Polygon.
What are BNB to Polygon Bridging Fees?
When it comes to bridging tokens from BNB to Polygon, understanding the associated fees is essential for users looking to make informed decisions.
The fees associated with BNB to Polygon bridging primarily consist of gas fees and bridge fees. Gas fees are the charges incurred for executing transactions on the blockchain and are determined by network congestion and the complexity of the transaction. On the other hand, bridge fees are specific to the bridge service being used and cover the costs of facilitating the token transfer between BNB and Polygon.
Due to the dynamic nature of gas fees, it's difficult to provide an exact figure for BNB to Polygon bridging fees. However, certain patterns can be observed. Gas fees tend to be lower during periods of lower network activity. Weekends, especially early in the morning around 4 AM Eastern Standard Time (EST), often see reduced congestion and lower fees.
To get the most accurate and up-to-date information on bridging fees, it is recommended to look into the bridge service you intend to use for the transaction. ChainPort, for example, charges a flat fee of 0.2 - 0.3% of the value of each token bridging transaction, one of the lowest fees for bridging.

What is a Cross Chain Bridge?
Interoperability plays a vital role in connecting different blockchain networks and enabling seamless asset transfers. One key infrastructure that facilitates this interoperability is a cross-chain bridge.
A cross-chain bridge is a technological solution that allows users to transfer assets between two distinct blockchain networks. It acts as a bridge, connecting disparate blockchain ecosystems and enabling the movement of tokens or assets across different chains. This bridge effectively links the source chain (where the assets are initially held) and the destination chain (where the assets will be transferred).
The process of utilizing a cross-chain bridge typically involves locking or depositing the assets on the source chain, which triggers the minting or creation of corresponding tokens on the destination chain. These newly minted tokens represent the equivalent value of the locked assets and can be freely transacted within the destination chain's ecosystem.
Cross-chain bridges rely on various underlying technologies, such as multi-signature wallets, decentralized oracles, and cryptographic algorithms, to ensure the secure and trustless transfer of assets between different chains. They often utilize smart contracts to enforce asset transfer rules and logic, providing transparency and accountability.
Benefits of Using a Cross-Chain Bridge
Cross-chain bridges offer significant benefits in terms of asset mobility, expanded market opportunities, interoperability, enhanced liquidity, risk diversification, and future-proofing. By leveraging these bridges, users can unlock the full potential of decentralized finance and seamlessly navigate the evolving blockchain ecosystem.
About BNB
BNB, short for Binance Coin, is the native cryptocurrency of the Binance blockchain ecosystem. It was initially launched as part of the Binance exchange, one of the largest cryptocurrency exchanges in the world. BNB has since evolved into a versatile digital asset that serves multiple purposes within the Binance ecosystem and beyond.
Formerly known as BSC (Binance Smart Chain), BNB is now widely recognized as an essential component of the Binance Chain, a high-performance blockchain built to facilitate fast and low-cost transactions. BNB operates on a proof-of-stake (PoS) consensus mechanism, which ensures network security and enables users to participate in staking and earn rewards.
BNB has gained significant traction due to its diverse utility and growing ecosystem. It serves as a medium of exchange, allowing users to pay for transaction fees, trade cryptocurrencies, and participate in token sales on the Binance exchange. Additionally, BNB powers the Binance Launchpad platform, which hosts token sales for promising blockchain projects.
Moreover, BNB is pivotal in DeFi applications on the Binance Smart Chain. Users can utilize BNB to access various DeFi protocols, participate in yield farming, lending, and borrowing, and provide liquidity to decentralized exchanges.
Furthermore, BNB holders can enjoy reduced fees when using BNB to pay for transactions and services within the Binance ecosystem. This utility has further enhanced the popularity and adoption of BNB among users.

About Polygon (MATIC) Network
Polygon, formerly known as Matic Network, is a layer 2 scaling solution for Ethereum that aims to improve scalability and usability while maintaining compatibility with the Ethereum network. It addresses the limitations of Ethereum's base layer, such as high transaction fees and slow confirmation times, by providing a framework for building and connecting multiple sidechains to Ethereum.
Polygon combines technologies, including Plasma chains, sidechains, and a decentralized network of validators, to achieve its scalability goals. It allows developers to create and deploy their scalable blockchain networks, known as Polygon sidechains, which are interoperable with the Ethereum mainnet. These sidechains benefit from faster block confirmation times and significantly lower transaction costs than Ethereum mainnet.
The native cryptocurrency of the Polygon network is called MATIC. MATIC is crucial in securing the network and is used for transactions, staking, and paying for gas fees on the Polygon sidechains.
