Best DeFi Bridges: Move Assets from ETH to BSC, Polygon & Vice Versa

Navigating the dynamic landscape of blockchain technology, one often encounters the need for efficient asset transfers. This is where the concept of bridging comes into play, acting as a vital conduit between different blockchains. Two such key players in this arena are Ethereum and Binance Smart Chain (BSC), with the ETH to BSC bridge and BSC to ETH bridge serving as crucial pathways for seamless asset transfers.

The bridge BSC to ETH and bridge ETH to BSC are not just mere technological constructs, but they represent the growing interoperability in the blockchain ecosystem. As the popularity of these bridges grows, so does the need for understanding their functionality and application.

In this article, we delve into the intricacies of these bridges, shedding light on their operation, and exploring their role in the broader context of decentralized finance. Whether you’re looking to move assets from BSC to Ethereum or vice versa, this comprehensive guide will provide you with the insights you need to navigate these bridges with confidence.

Since 2024, interoperability has shifted from smaller experimental bridges toward large, audited protocols like LayerZero, Wormhole, and Circle’s native USDC transfers – which now move billions monthly.

How to Move Assets from Ethereum to BSC ETH to BSC Bridge


Before we get started – if you’re in the US, your First Amendment rights don’t yet extend to moving value from one blockchain to another. Should you wish to attempt any of the following, you will need to be behind a VPN. There are dozens of free browser extensions here, so take your pick. This week I’m mainly using KProxy and, with much constitutional irony, I’m pretending to be Canadian.

This unnecessarily awkward process is thus. At the top of the MetaMask wallet, click “Ethereum Mainnet” and select “Custom RPC” at the bottom of the dropdown list. To add Binance Smart Chain Network as an option, enter the following details – 

  • Network Name – Binance Smart Chain
  • New RPC URL – https://bsc-dataseed.binance.org/
  • Chain ID – 0x38
  • Currency Symbol – BNB
  • Block Explorer URL https://bscscan.com/

Once you click save, Binance Smart Chain will be listed in the network options. All these details are available here on the Binance website, along with more thorough instructions. 

Like I said before, this bridge should just happen automatically without all this messing about. How on earth do DeFi platforms expect to become mainstream when you need most of an afternoon and an undergraduate degree in computing to make them work? The first universal wallet that completely does away with all this nonsense will have a huge advantage. 

Regardless, once your wallet is set up with BSC as a network option, you can make the transfer. Choose –

  • The asset you would like to move 
  • The source network (Ethereum) 
  • The target network (Binance Smart Chain) 
  • The amount

You will need to confirm both on the Binance Bridge page and your wallet, and the transfer should take around 10-15 minutes. Pro-Tip – You may need to refresh your wallet if it gets confused about whether to display BNB or ETH.

How to Move Assets Back from BSC to Ethereum


Bridge and Swap for Binance Chain and Binance Smart Chain


You may have noticed that there are two Binance chains. The one we’ve been using so far is Binance Smart Chain. So what’s Binance Chain all about? It’s worth knowing so you don’t send tokens to the wrong chain and end up losing them. 

The more recent Binance Smart Chain (BSC) is the proprietary blockchain network Binance uses to interact with the DeFi world. It’s EVM compatible (Ethereum Virtual Machine) so it can understand and execute Ethereum smart contracts. BSC can easily onboard platforms built on Ethereum and offers much cheaper and faster transactions. 

You can move your crypto between the Binance DEx and the BSC chain by selecting the appropriate source and target networks. 

BSC To Polygon Bridge: How to Move Assets from BSC to Polygon Network (Matic)


Your Metmask wallet address should automatically appear in the receiver address box, but it’s a good idea to check this manually to avoid disaster. Once you are sure, click “Swap” and another window will open where you can choose how much of your chosen stablecoin you wish to transfer. 

Once the transfer is complete, you need to select your target network on Metmask to view the tokens in your wallet. This is important! The first time I went through this process, I couldn’t see the tokens in my wallet and thought I had made a fatal error! 

How to Move Assets from Ethereum to Polygon


Polygon has built its own Bridge to move tokens cross-chain to their Matic network. You can find it here. Upon opening the page, the drill is the same as all the other bridges. You connect your Metamask wallet and the bridge main window appears. Enter the usual info – source and target network (Ethereum and Matic), Token, and amount. You can move ETH or any ERC20 token you have in your wallet. 

Best DeFi Bridges in 2025/2026


Rubic


Rubic is the premier Multi-Chain Protocol, enabling swaps between about 10,000 assets, on and between the Ethereum, Polygon, BSC, Avalanche, Moonriver, and Fantom blockchains. It all happens in one click while granting you better rates and lower fees. Cooperating with numerous DEXs for expanded exchange options allows Rubic to choose the best rates for their users, so they rest easy while getting the lowest possible transaction fees.

Rubic integrates one new blockchain for Multi-Chain Swaps on a monthly basis. Recently, Rubic integrated Moonriver (November 8th) and  Fantom (November 18th).

The swap process is very simple, as users don’t have to take part in endless transactions in order to get their desired assets. The only con is that, like every similar protocol, there exists the possibility of a transaction’s reversion, due to changes in exchange rates. Despite this occasional network-based issue, Rubic remains the most reliable way to swap your assets across chains, and their growth is still only beginning.

LayerZero (Stargate Finance)


LayerZero has become one of the leading cross-chain protocols, powering seamless transfers across Ethereum, BNB Chain, Polygon, Avalanche, Arbitrum, Optimism, Base, and more. Its Stargate Finance app is the main gateway, offering deep liquidity pools and one-click swaps. With billions in cumulative volume and integrations across dozens of DeFi apps, Stargate is now one of the safest and most reliable bridges available.

Wormhole


Originally built to connect Solana and Ethereum, Wormhole has grown into a universal interoperability layer. It now supports over 20 networks, including Aptos, Sui, Cosmos chains, and Ethereum Layer 2s. Wormhole is widely used for moving NFTs, tokens, and cross-chain liquidity, with major wallets and DeFi platforms already integrating it.

deBridge


deBridge positions itself as a secure, institutional-grade bridge and cross-chain messaging protocol. It enables not just asset transfers but also advanced functions like cross-chain governance and oracles. Its strict focus on security audits and real-time monitoring has earned it adoption among DeFi projects and DAOs that require reliable interoperability.

Synapse Protocol


Synapse remains one of the most popular community-driven bridges, especially for Ethereum L2 ecosystems. It supports Arbitrum, Optimism, Base, Polygon, Avalanche, and Fantom, offering fast swaps and strong liquidity. Synapse is known for its smooth UX and relatively low fees, making it a go-to bridge for stablecoin transfers.

Circle’s Cross-Chain Transfer Protocol (CCTP)


CCTP is Circle’s official protocol for moving USDC natively across blockchains. Instead of wrapped tokens, CCTP burns USDC on the source chain and mints fresh USDC on the destination. This has quickly become the most secure and widely trusted way to bridge stablecoins, with integrations in leading wallets, DEXs, and DeFi platforms.

Centralized Exchanges 


As I mentioned before, technology like Cross Chain Bridges should not even be visible to the user. It should be integrated into wallets and DExs so the customer does not have to consider on which blockchain their assets sit. Currently, the technology is for enthusiasts and early adopters. By the time it becomes mainstream, there’ll be better solutions.

  1. Umbria Narni bridge is also a fast and inexpensive DeFi bridge option. It bridges selected assets from ethereum to polygon, bsc, fantom, and avalanche. Smaller project, but has a responsive, doxxed team of devs. Worth a look

  2. Second that. They also have bridges for Optimism and Arbitrum in addition to those you’ve listed.
