Wondering how to switch between blockchains? Using cross chain bridges in DeFi ecosystem you can easily swap / transfer tokens, NFTs and other digital assets / data from one blockchain to another.
Just recently we’ve made a post explaining what are bridges and how cross chain swaps work? You can read that to know more about blockchain bridges where we also mentioned the benefits of bridges in the DeFi ecosystem.
We explained everything about bridges but we failed to list out the platforms where you can perform these cross chain activities. So here it is the list of DeFi bridges that connect you to different blockchains. It includes both centralized and decentralized bridges. Also cross chain, multi chain as well as side chain token bridges.
Transfer assets between blockchains
Today there are many blockchains providing DeFi products and services that open up financial solution to anyone with just an internet connection. You got Ethereum, Polkadot, Cosmos, Cardano, EOS, Tron, Algorand, Avalanche, Tezos, Solana, Arbitrum, Binance Smart Chain, Matic (Polygon), Fantom, Near, Optimism, Harmony, WAX, Terra and many others.
There are billions of dollars locked across these platforms. With a great deal of value flowing across these blockchains a connection between these network becomes essential to ensure scalability and to bring connectivity across the DeFi ecosystem.
Bridges in DeFi are very much useful as it provides an easy way for users to bridge cross-chain assets between blockchains. It allows users to access variety of decentralized finance (DeFi) applications across various networks. You can use these bridges not only to perform cross chain token swaps. Once the assets are transferred you can use them to stake, earn yield and perform variety of DeFi activities on the network of your choice.
Bridges – Cross chain and side chain bridges
There are many platforms offering cross-chain swap functionality. Interestingly most of these bridges can connect to the main Ethereum (ETH) network.
Also most projects are in the process of rolling out bridge technology to increase scaling solutions. For example: projects such as Avalanche, Polkadot, Kusama, and Cosmos IBC (Inter-blockchain communication) are already experimenting with the network composability and cross-chain interoperability.
The goal is to bring more liquidity onto the network by enabling token holders to transfer their assets across the bridge to be used in decentralized applications in variety of circumstances.
So some of the bridges listed here only connects L1 and L2 that is connecting parent and child chain. This is typically a side chain bridge mostly connecting Ethereum mainnet to the Layer 2 allowing the transfer of tokens.
Some on the other hand are specifically designed to connect only the substrate and EVM (Ethereum Virtual Machine) based chains which you can use to bridge assets between two blockchains. Then there are bridges that can connect multiple blockchains.
Other than protocols with bridging solutions there are also exchanges both CEX and DEX providing cross chain swap functionality which you can use to swap assets between a myriad of networks. Once the swap is complete you can interact and facilitate transaction on other blockchains.
Below you can find the list of bridges that cryptocurrency and DeFi participants can use to perform cross chain activities. Along with that we’ll also highlight top projects that are building bridges between chains. Using these tools you can potentially connect to any type of chain and in any direction allowing you to transfer assets in a permission less way.
List of Bridges
First of all most of the bridges listed here all function the same. In order to transfer tokens across chains using these bridges all you have to do is connect your Web 3 wallet like Metamask or Trust Wallet. But mostly you’ll only need Metamask.
Then make sure your Metamask is connected to the correct network. For example if you want to swap tokens from BSC to Ethereum then ensure the Metamask network is selected to BSC. Likewise if you want to swap assets from Avalanche to BSC then connect your Metamask to the Avalanche network.
Here are few guides that you can make use of:
- Connecting Metamask to Binance Smart Chain
- Beginners guide to Solana SPL token wallet and Adding custom tokens to Solana wallet
- Transfer / Convert ERC20 to & from SPL
- Adding Arbitrum network to Metamask
- Connect Metamask to Avalanche network
- Guide to connect Metamask to Polygon (Matic network)
- How to add custom tokens to Metamask wallet
Hope these are helpful.
Alright! Now here goes the list of DeFi bridges that you can use to bridge assets across chain which is swap assets, earn yield & perform variety of DeFi activities on the network of your choice.

Now before you connect and start using these bridges here is something that you need to know.
Cross Chain Bridges and DeFi – Risk warning
Each bridges listed here uses different security model to protect users from fraud. They have different incentives to keep the transactions going and also have different limitations.
By using bridges in DeFi you can experience the power of cross-chain. However it is important to keep in mind that the features and the underlying technology behind these protocols are still in the early beta stage. You need to conduct your own research and you should understand the DeFi risks before using these platforms.
You need prior knowledge to use these cross chain bridges. Unlike CEX if you make a mistake then your funds can get lost forever. So do your due diligence and learn how to use cross chain bridges. Only if you understand you should access these cross-chain bridges or any decentralized finance (defi) applications in general.
