Bitfrost is also planning to work on interoperability with EOS contracts. The siloed nature of today’s blockchain networks goes against the principle of decentralization and re-establishes the Balkanization of the existing centralized web (often called Web 2.0). According to DeFi Llama, there was $21.8 billion worth of crypto locked in bridges as of March 2022. The largest blockchain bridge is Wrapped Bitcoin, accounting for almost half of the bridge market, with $10.2 billion in total value locked . DeFi Llama pegs Multichain as the largest cross-chain bridge, with about $7 billion in TVL. Other bridges like Wormhole and Multichain are bidirectional, or two-way, meaning you can freely convert assets to and from blockchains.
This results in a boost in security, where governance is similar to that of the blockchain technology itself. As a result of the use of smart contracts, users are empowered to keep control of their funds and assets. Blockchain networks deploy different fragments of code to help developers in deploying applications, tokens and smart contracts over a network. In addition, all blockchain networks feature their own token standard and framework, offering opportunities for development.
Like the currency exchange we made for EUR, we need a mechanism to move our ETH from Ethereum to Arbitrum. In this case,Arbitrum has a native bridgethat can transfer https://xcritical.com/ ETH from Mainnet onto Arbitrum. Burn and mint—A user burns tokens on the source chain, then the same native tokens are re-issued on the destination chain.
It also provides general message bridging for cases such as cross-chain DEX and NFTs. Other exciting features include secured bridge node service, flexible security models, and native gas token unwrapping. Blockchain bridges solve this problem by enabling token transfers, smart contracts and data exchange, and other feedback and instructions between two independent platforms.
Stargate Bridge
With this in mind, let’s break down the concept of blockchain bridges and understand it in simpler terms. A blockchain “bridge” connects two blockchains and allows users to send cryptocurrency from one blockchain to another. Smart contracts enable users of trustless bridges to keep control of their finances.
Blockchain bridges can be categorized according to their functions, mechanisms, and levels of centralization. Network security encompasses all the steps taken to protect the integrity of a computer network and the data within it. Binance Bridge, Celer cBridge and Wormhole are just a few of the cross-chain bridges available today. Manual checkpoints are similar to a trusted model as it depends upon a third party, i.e., the officials, for its operations.
Decentralized bridges do exist that are trustless and you do not give up control of your coins at any point. These bridges operate like a blockchain with networks validating transactions. In addition, because programs designed for one network only operate on that network, this has led to a lower adoption rate. A significant limitation of blockchain solutions is the interoperability problem.
The Challenges of Cross-Chain Bridging
Although blockchain technology has proven to be effective in some scenarios, it has a siloed nature, preventing the progress of DeFi and other decentralized applications. Rather than utilizing the functionalities of different dApps to facilitate growth, the technology is limited due to the lack of communication between separate chains. The blockchain bridge by Binance serves as a bidirectional bridge between Ethereum and the main Binance chain. It also utilizes specific features of the Ethereum-compatible BNB Smart Chain for wrapping token assets. The Binance Bridge helps users utilize Ethereum-based assets on the BNB Smart Chain by wrapping tokens in the BEP-20 token standard. The bridges provide seamless transactions between popular blockchain networks.
We already mentioned that blockchain bridges enable interoperability between different networks, like Ethereum and Bitcoin, for example. But to fully understand bridges in blockchain, it’s important to go back to the basics of the technology. The important thing to remember here is that each blockchain has its own standard, its own set of rules that is rarely compatible with other chains. List of blockchain bridges focused on addressing unique user requirements. Here is an outline of the notable blockchain bridge variants you can use for transferring assets and information between blockchain networks.
- Censorship Risk — bridge operators might hypothetically prevent users from moving assets across the bridge.
- But what if you want to perform a similar transaction with a different blockchain?
- For example, Terra Bridge allows you to move funds from Harmony or Ethereum to Terra and vice versa, but it doesn’t allow you to move funds when neither source nor target blockchain is the Terra blockchain.
- They enable innovation in protocols, leading to new and creative solutions.
- On the other side, Blockchain bridges allow coins and information to be transferred from one chain to another.

With a wrapped token, the value of one token from a specific blockchain network can be encapsulated inside another token. Wrapped tokens are typically based on the ERC-20 technical specification for an Ethereum network. For example, WBTC is a Bitcoin token wrapped with an ERC-20 Ethereum smart contract. One characteristic of a cross-chain bridge is that it enables users to exchange one cryptocurrency for another without first changing it to fiat currency.
Despite the fact that bridges in their ultimate form may be bullet-proof solutions, today, they’re still relatively new. In their nascent phase, bridges bring several challenges to the blockchain table. The zero-trust security model is a cybersecurity approach that denies access to an enterprise’s digital resources by default and …
Are there risks to using blockchain bridges?
The hacker created a fake deposit event that was transmitted to the bridge without any legitimate deposit. DApps can combine the strength of various blockchains to enhance their capabilities. Examples of the chain-to-chain bridge are the ETH – RSK token bridge, the Avalanche Bridge and the Binance – Ethereum bridge.
If we were able to combine the capabilities of these continents, we’d have a prosperous world. But without a way to connect their distinct economies by way of shipping, bridges, tunnels, or other infrastructure, these regions would be unable to derive benefit from their capabilities. Continent A would be without food, Continent B wouldn’t have the technology to maximize its food production efficiency, and Continent C wouldn’t have the resources to manufacture the best products. All bridges have different designs and trust assumptions, so make sure to do your due diligence on each bridge before interacting with it. You can do this by checking the documentation and code and observing how mature it is.
A hot wallet is susceptible to hacking as it is connected to the internet, but the cold wallet is much more secure. Hot wallets are third-party applications and might have security vulnerabilities. Recently, around 8,000 hot wallets, mainly Trust wallet and slope wallet, were hacked using a Supply Chain Attack to steal the private keys and drain the wallets. Although blockchain technology is revolutionising how we interact online and has emerged as a worthy opponent to the traditional banking system, it is also susceptible to hacking.

The enormous demand for blockchain solutions has led to an increase in blockchain protocols and the need for blockchain communication. The blockchain bridge will continue to grow in the future, too, as the Internet is moving to Web3. Since blockchain assets are often not compatible with one another, bridges create synthetic derivatives that represent an asset from another blockchain.
Lock and Mint: The Lynchpin of Decentralized Bridges
Similarly, high transaction fees and congestion on the Ethereum network raise the need for blockchain bridges, encouraging users to move their assets to a Layer-2 blockchain network such as Optimism or Polygon. As blockchain technology innovates quickly, more cross-chain trustless bridges are created in order to help with bridging assets from one blockchain to another. An example of a trustless cross-chain bridge is XDEFI Wallet’s cross-chain swap functionality using THORChain. You can swap native Bitcoin on the Bitcoin network to native Ethereum on the Ethereum network without trusting a centralized bridge. Both reliable and trustless methods may have underlying technological faults.
What Are Blockchain Bridges, and Why are they Important for DeFi?
You can solve this problem by using a blockchain bridge to move your assets across different chains. For instance, you can use BTC as collateral for the wBTC, which can be used on the Ethereum blockchain. This ensures that cryptoassets produce extra value, instead of lying dormant on one blockchain. The multichain erc20 vs kcc future is a present reality as newer blockchains continue to launch. Per stats, there are 125+ Layer 1 and Layer 2 blockchains, each offering unique tradeoffs, security guarantees, scalability, and so on. With the explosion in blockchains comes a need for better interoperability in the blockchain ecosystem.
Today, interoperability between blockchains is facilitated by many of the best blockchain bridges in the crypto space. Cross-chain bridges work by “wrapping” tokens in a smart contract and issuing native assets you can use on another chain. For instance, wrapped BTC is an ERC-20 token that uses BTC as collateral. Users must deposit BTC on the Bitcoin blockchain before receiving wBTC tokens on the Ethereum network. Interest in blockchain bridges is a result of the expansion of the blockchain ecosystem.
In addition, you can also learn about the risks of a blockchain bridge and examples of projects. 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.
