6 best cross-chain bridges in 2022
Content
User X is in a quandary if they wish to pay user Y for something, but Ethereum only takes ETH. Due to the interoperability provided by bridging solutions, they can still buy ETH or convert part of their BTC into ETH. It’s a disadvantage compared to regular fiat transferring/exchanging since fiat currencies and many banks and financial institutions can utilize credit cards.
If a bridge’s developer copy pastes code from another bridge, they may copy the same vulnerabilities.
Web3 has developed into an ecosystem that consists of L1 blockchains and L2 scaling solutions. Each of these solutions was created with its own set of capabilities and trade-offs. The need to transfer assets between different blockchains is growing at the same rate that the number of blockchain protocols is expanding.
Sidechain Bridges
For example, developers can benefit from the lower fees offered by the different L2 solutions by deploying their dapps across rollups, and sidechains and users can bridge across them. Technically, the operator hosting the Custodial blockchain bridge can seize the funds of all its users, or even close the bridge to prevent users from transferring assets. Considering that assets from one blockchain are usually incompatible with foreign blockchains, the bridge is actually an asset of another blockchain. For example, if you want to bring bitcoin to the Ethereum blockchain for consumption, the bridge will wrap bitcoin in a blank code to make it compatible with the target blockchain. In the case of Ethereum, the bridge just turns bitcoin token into ERC-20 t token — Ethereum’s native replaceable token — which makes it usable like Ethereum’s native token. It also provides general message bridging for cases such as cross-chain DEX and NFTs.
For instance, the trusted blockchain bridge raises worries about censoring because of centralized management. Additionally, users may be impacted by the custodial risks of exposing assets to fraudulent bridge operators. In addition, a trustless bridge would put the smart contract code at danger from malware or other bugs.
Different Types of Blockchain Bridge
Web3 has now evolved into a distributed ecosystem due to the introduction of side chains. But both of these original chains and scaling solutions come with their unique features and trade-offs. As more blockchain technologies are developed, there is an increasing demand for asset transfers. Blockchain bridge projects, the web3 ecosystem could become stronger and more immersive for users. The following discussion offers a detailed introduction to a blockchain bridge and its working alongside the value advantages it presents for the blockchain community. In addition, you can also learn about the risks of a blockchain bridge and examples of projects.
Other exciting features include secured bridge node service, flexible security models, and native gas token unwrapping. The future of decentralized blockchain networks necessitates easy interaction and interoperability. Since the founding of Bitcoin in 2009, there has been a surge in the number of blockchain networks with varying designs and functionalities.
It has seen significant increase in use given very generous returns from applications like Anchor with a 20% APY. Darwinia – Using a light client approach for native verification on Ethereum and a number of other popular chains. As challengers to Bitcoin and Ethereum have emerged so have solutions to bridge between the growing number of layer 1 chains. For that reason Ethereum bridges are crucial to growing DEFI, and naturally, one of the first to emerge was with Bitcoin through what is known as wrapped Bitcoin. The Nodes are continually verifying new blocks of data based on that mechanism. That could be recent Bitcoin transactions or updated Ethereum account balances.
But, what do you do if you want to make a similar exchange to use a different blockchain? Let’s say you want to exchange ETH on Ethereum Mainnet for ETH onArbitrum. Like the currency exchange we made for EUR, we need a mechanism to move our ETH from Ethereum to Arbitrum.

Ronin discovered the breach that day, but the platform’s “validator nodes” had been compromised on March 23. Ronin Bridge has been down ever since, and users can’t carry out what is a blockchain bridge and how it works transactions on the platform. Polkadot provide an interesting dimension to the interoperability debate, positioning itself as the blockchain of blockchains, or layer 0.
- As more blockchain technologies are developed, there is an increasing demand for asset transfers.
- When you want to convert back to BTC, the ETH you had or whatever’s left of it will get burned and an equal amount of BTC goes back to your wallet.
- Non-custodial bridges operate in a decentralized manner, relying on smart contracts to manage the crypto locking and minting processes, removing the need to trust a bridge operator.
- Other exciting features include secured bridge node service, flexible security models, and native gas token unwrapping.
- In blockchain bridge, another crypto’s tokenized version is often referred to as a wrapped token.
The other natural off-chain destination for Solana assets is Bitcoin and similar PoW chains. REN VM Bridge again uses the lock-and-mint approach to bridge BTC, BCH, ZEC and DOGE. Solana has huge appeal as a layer one chain given the significant throughput it can achieve, with 50,000 transactions per second, compared to Ethereum with just 30. As Solana and its ecosystem have developed the need for bridges quickly emerged. One of the most popular Ethereum-Bitcoin bridges is Bitgo, which uses the centralised bridge approach.
Disadvantages of blockchain bridges
DEFI includes a whole range of financial services for crypto users, such as lending/borrowing and swapping. Given the problem of blockchain interoperability a significant proportion of the value within the crypto system is locked out of Ethereum-based DEFI applications. They exist as isolated domains with unique operating logic, prioritising security and decentralisation.
With separate rules and technologies, they need blockchain bridges to be interconnected. A blockchain ecosystem linked by bridges is more cohesive and interoperable, opening up opportunities for better scalability and efficiency. With numerous attacks on cross-chain bridges, the search for a more secure and robust bridge design continues. A one-way bridge means users can only bridge assets to one destination blockchain but not back to its native blockchain. To understand what a blockchain bridge is, you need to first understand what a blockchain is. Bitcoin, Ethereum, and BNB Smart Chain are some of the major blockchain ecosystems, all relying on different consensus protocols, programming languages, and system rules.
What are Blockchain Bridges and How Do They Work?
However, because each sidechain is isolated, any security impairment will only affect the sidechain itself and not the main chain. To stay updated on key developments in the DeFi space, follow the MakerDAO blog. We make every effort to ensure that the content is reliable and qualitative. One of the primary reasons for these hacks, as stated by CoinTelegraph, is open-source code and copy-pasting code. With open-source code, blackhat hackers can review a bridge’s code for vulnerabilities.

Asset exchange and asset transfer are the most common forms of cross-chain implementation. Both are essential aspects of the blockchain world and a crucial study focus for PPIO . Users can make and receive microtransfers quickly and without paying high transaction fees, enabling better gaming and ecommerce experiences. Wrapped Bitcoin and similar projects, such as imBTC and HBTC, each provide a simple and effective solution to the problem of moving value across siloed blockchains.

The Avalanche Bridge can be used to transfer assets between the Avalanche proof-of-stake blockchain and Ethereum. According to the documentation, an Avalanche transaction on AB will take a few seconds, while an Ethereum transaction may take up to 15 minutes. The Wrap Protocol, which as of this writing will soon be rebranded as the Plenty Bridge, can be used to transfer ERC20 and ERC721 tokens between the Tezos network and Ethereum, Polygon, and BSC. The Tezos blockchain uses validating nodes known as bakers to implement its proof-of-stake consensus algorithm. Portal offers unlimited transfers of assets between Solana and several other DeFi blockchains, such as Ethereum, Terra, Binance Smart Chain, Avalanch, oasis, and Polygon.
Trusted (Centralized) Bridges
One minor gripe you might have with cBridge is you need to connect a wallet before doing anything. Here are some of the most talked-about blockchain bridges you can use to transfer https://xcritical.com/ crypto. These blockchains mint different coins and operate on different sets of rules; the bridge serves as a neutral zone so users can smoothly switch between one and the other.
They need a neutral system for accurately verifying transactions that can make sense to each planet separately, without relying on trust and which neither side can manipulate—an interplanetary information bridge. This is because users will have all sorts of networks to utilize, using dApps on EOS and Bitcoin instead of everyone clogging up Ethereum. Bridges opt to solve the scalability problem, as the load from many smaller transactions (via games and NFT trades, etc.) is lifted from the main Ethereum chain. Now, it’s worth noting that you’re not actually sending ethereum to tron . Rather, the ethereum you’re “sending” is actually locked within the network.
Without bridges each blockchain has a monopoly on what users of their supported assets can do. As more bridges connect to each of the layer 1 blockchains and their layer 2 applications, that monopoly is broken and users have more choice in how they transact. Ethereum is the dominant blockchain for supporting decentralised applications, particularly in the sector known as DEFI – decentralised finance.
