Definition of a Cross-Chain Bridge
Before you try searching for a list of cross-chain bridges, it is essential to learn what they are. Cross-chain bridges are an innovative solution for bridging between two distinct blockchain networks, thereby enabling the easier exchange of information and assets. Cross-chain bridges are an essential tool for exchanging siloed assets and data in blockchain networks with different blockchains. Upon building a cross-chain bridge, you can ensure easier transfer of funds and access to other functionalities without any glitches on the blockchain networks of your choice.
The outline of the most popular cross-chain bridges is an essential requirement for crypto and web3 users right now. Cross-chain bridges could guarantee significant benefits such as better user experiences and more opportunities for achieving asset productivity. In addition, cross-chain bridges could also ensure that developers could leverage the liquidity accessible on different platforms, thereby improving liquidity for concerned dApps.
Most of the cross-chain bridges follow the “Burn and Release” or “Lock and Mint” approaches for enabling blockchain interoperability. For example, the bridge would lock tokens on one blockchain and mint tokens on another blockchain with the same value. After minting on the new blockchain, owners can decide the release or unlock the tokens on the first blockchain.
Significance of Cross-Chain Bridges
You can identify the answer to “What are the best cross-design bridges?” with more emphasis on their value by understanding the importance of cross-chain bridges. First of all, you need to know that cross-chain crypto bridges are unidirectional and help in sending assets to one blockchain network only. On top of it, you can also find multichain bi-directional bridges for enabling two-way asset transfer among two chains.
Cross-chain swaps can work by creating synthetic derivatives for assets on the native chain to ensure compatibility with the destination chain. For example, if you want to transfer ETH to Binance Chain, then the bridge would create a wrapped token for ETH in a format compatible with BEP-20 format and send it to the user’s wallet. The simple process helps in resolving the problems with interoperability.
As a result, users could make the most of high speed and scalability as well as the advantages of low cost in other chains you can find in the industry. Decentralized applications could improve their functionalities with access to top features on other popular blockchains. Developers could also collaborate across multiple blockchain platforms to ensure a better quality of decentralized applications.

Top Cross-Chain Bridges in Crypto
The concept of cross-chain bridges offers a significant value improvement in services accessible to blockchain developers and users. An outline of the best cross-chain bridge crypto solutions could help you pick the ideal choice according to your requirements. The most popular cryptocurrency, Bitcoin, utilizes the Wrapped Bitcoin or WBTC as a bridge. It helps in converting Bitcoin into an ERC-20 token, which is acceptable on different blockchain networks. However, Bitcoin does not have the features of smart contract programmability, which make Ethereum a top choice for DeFi, NFTs, and dApp development.
Cross-chain bridges could help in offering support for different variants of blockchain, albeit with varying levels of support from one provider to another. The top cross-chain bridges could help in taking the value of smart contracts, NFTs, and tokenization outside the Ethereum blockchain to different networks. Here are some of the most notable cross-chain bridges you can try out now.
1. Binance Bridge
The first choice among the best cross-chain crypto bridges would refer to the popular Binance Bridge. It is a trusted option for enabling the transfer of assets from Ethereum to the Binance Smart Chain. As a trusted Ethereum-Binance Smart Chain bridge, the Binance Bridge could help anyone in converting crypto tokens into formats compatible with Binance Chain and BSC.
It can also help in converting the tokens back into Ethereum-compatible formats. The Binance Bridge offers support for converting ERC-20 tokens as well as a few other coins on different networks. Some of the supported coins on Binance Bridge include XRP, ONT, LINK, XTZ, DOT, and ATOM.
The work of Binance Bridge as one of the best cross-chain bridges is easy to understand, thereby enabling better usability. Upon receiving a request for token transfer, the bridge would wrap and convert the ETH tokens into BEP formats. After completing the conversion, the tokens can be implemented as the native BEP-20 tokens in swapping and staking activities throughout different protocols in the Binance Smart Chain ecosystem.
The conversion process is simple and can be completed within a few minutes for bridging tokens among the networks. Interestingly, the Binance Bridge is a unique choice in the list of cross-chain bridges as it does not charge any transaction fees. Users should only pay for the gas fees on the source and destination blockchain networks. In addition, the Binance Bridge interface is accessible to any user without the need for a Binance account.

2. Avalanche Bridge
The next prominent entry among the most popular cross-chain bridges refers to the Avalanche Bridge. It is a bi-directional cross-chain crypto bridge working between the Avalanche and Ethereum blockchain networks. The Avalanche Bridge or Avax Bridge offers a better alternative to the traditional Avalanche-Ethereum Bridge or AEB. The Avalanche Bridge could enable the seamless transfer of assets among the two networks, thereby fuelling the growth of Avalanche.
Avalanche Bridge is the best cross-chain bridge the crypto industry has right now, and you can validate the same from its working. It works by using the ChainBridge of ChainSafe and enables two-way transfers of crypto tokens as well as NFTs. Users could request cross-chain swaps or use ERC-20 tokens in the dApp ecosystem of Avalanche. All users have to do is deposit and lock their tokens in the ChainBridge smart contract.
After the assets have been deposited and locked, the bridge creates a proposal and sends it to the relayers. The relayers on Avalanche Bridge, such as Avascan, Protofire, POA Network, and Hashquark, work on ensuring the security of the bridge. Relayers would compare the proposal with data available on the Avalanche blockchain and use a voting process for approval or rejection of the proposal. With the assurance of a voting process, Avalanche serves the benefit of additional security in transferring assets.
