Web 3.0 is on the rise, and the industry is booming now more than ever. As the market keeps growing and evolving, we also see new user needs and demand rise. This has led to the development of cross-chain crypto bridges. Essentially, bridges are platforms that enable the transfer of crypto assets from one blockchain to another. These assets can include anything from cryptocurrency to NFTs.

As the need for a seamless flow of data is growing, crypto bridges have become more and more significant. With so many options to choose from, it is natural to wonder what are the best crypto bridges in the industry right now.

In this article, we solve that question and give you a list of the best crypto bridges to choose from in 2024.

What are Crypto Bridges?

In the world of cryptocurrencies, a crypto bridge refers to a platform that allows the transfer of one cryptocurrency from one chain to another, without the need for a centralized intermediary like a traditional exchange. These cross-chain bridges can help facilitate transactions between different blockchain networks and enable the transfer of assets from one blockchain to another.

Let’s take an example to understand it better.

Let’s say that Kane is a cryptocurrency trader who wants to buy some tokens on ZkSync, a new blockchain network that is not yet widely supported on traditional exchanges. Kane holds Ethereum, but the new tokens he wants to purchase are only available on the new network’s native blockchain, in this case, which is ZkSync.

To get the new tokens on the ZkSync blockchain, Kane could use a crypto cross-chain bridge that supports both Ethereum and ZkSync, the new network’s cryptocurrency. He would first deposit his Ethereum into the bridge’s platform, and the bridge would then after deducting a small fee deposit the Ethereum into the new cryptocurrency at the current market rate.

Once the transfer is complete, Kane can then swap ETH to the new cryptocurrency on ZkSync. He could then hold the tokens or trade them on the new network’s decentralized exchange.

Without a crypto bridge, Kane would need to find a centralized exchange that supports the new tokens, which could be difficult or impossible if the tokens are not yet widely traded.

A crypto bridge enables Kane to access the new tokens without the need for a centralized intermediary and allows for more efficient and decentralized trading across multiple blockchain networks.

Now that we have understood what crypto bridges are, let us take a look at the top 7 cross-chain crypto bridges to use in 2024.

Top 7 Crypto Bridges to Use in 2024

It is feasible to perform cryptocurrency exchanges without a bridge, but it can be both costly and time-consuming. If users opt not to use a crypto bridge, they must use a centralised exchange to move funds from one blockchain to the other. However, this is something a lot of the users do not want to opt for as they want to stay anonymous.

With a multichain crypto bridge, this process is simplified and made easy for users.

However, all the benefits of bridges are only actually helpful when you use a dependable platform. The bridge you choose must be the best option possible. The seven best options for a crypto bridge in our opinion are:

  • Across Protocol
  • Stargate Finance
  • Orbiter.Finance
  • Allbridge
  • Synapse
  • HopBridge
  • Portal Bridge

Across Bridge

Across Protocol is a top choice for cross-chain bridging, offering the fastest and cheapest way to transfer assets between different blockchains. It’s the only cross-chain intents protocol currently in production, providing seamless interoperability without compromising security.

Across bridge

Till date, Across has already facilitated over $10 billion in transaction volume through 6 million transactions.

In the list of top crypto bridges in 2024, I have mentioned Across Protocol as the top crypto bridge and I have my reasons.

Why I Choose Across Protocol as the best Crypto Bridge in 2024?

While choosing a crypto bridge, most of the users look for a few important things that I have taken into account, writing this. Across is also my preferred crypto bridge, and below mentioned are my top 3 reasons:

  1. Cost-Effective: Across is the most affordable option for cross-chain bridging I’ve found. Before using any blockchain, I always check if Across supports my needs. If it does, I go with Across. If not, I look for alternatives.
  2. Speed: Across is incredibly fast, with an average fill time of less than a minute.
  3. Security: Users don’t face any risks because relayers handle all the transactions, ensuring secure and reliable operations.

Current Limitation: Across currently supports only a few blockchains. I’m hopeful they will add more soon to expand their reach.

If you’re looking for the best multichain bridge in 2024, Across Protocol is the way to go. It combines speed, affordability, and security, making it the ideal choice for cross-chain transactions.

Stargate Finance

Stargate is a liquidity transport protocol powered by Omnichain DeFi. Stargate enables users to seamlessly transact across various blockchains while enjoying unparalleled liquidity and minimal slippage, making it the preferred cross-chain bridge for large transactions. Unlike custodial solutions, Stargate’s cross-chain bridge is decentralized and enables cross-chain swaps at a nominal fee structure. Recently Stargate has pushed a V2 upgrade, and the platform has become less expensive.

Stargate finance

As of July 8 2024, the platform boasts a staggering Total Value Locked of nearly 459M US dollars, a testament to its growing user base and unrivaled value proposition.

With Layerzero tech, Stargate empowers users and decentralized applications to exchange utility assets across different blockchains while enjoying suitable liquidity pools that provide rapid and irrevocable finality. Transfers made through Stargate are assured to be successful on the destination blockchain, as long as they have been submitted on the source blockchain. Liquidity providers using Stargate can earn generous annual percentage yields ranging from 5% to 10% in the form of STG incentives. They can also participate in yield farming by staking their LP tokens in exchange for STG rewards.

Historically, cross-chain bridges have had to compromise on one or more of the fundamental features that define them: irrevocable finality, native asset support, and unified liquidity. Prior bridge solutions often had to give up at least one of these aspects to deliver a functional product. However, Stargate has pioneered a solution to this trilemma, becoming the first cross-chain bridge to offer all three features in a single platform. Stargate supports a diverse range of blockchains, including Ethereum, Binance Smart Chain, Avalanche, Polygon, Arbitrum, Optimism, and Fantom.

Stargate offers a unique value proposition in that it enables applications to natively facilitate cross-chain transactions. For example, Yield aggregators can integrate Stargate to unlock new APY prospects by seamlessly deploying assets across different blockchains. Stargate’s cross-chain swap fees are remarkably low, starting at 0.1% per trade. The platform supports a broad range of tokens, including ETH, WETH, USDC, USDT, DAI, FRAX, SUSD, and BUSD.

Stargate.finance is my go-to bridge for any kind of cross-chain transfer, where services of Across Protocol is not available. I find it to be easy to use. Funds are transferred fairly quickly and the charges are very cheap.

Orbiter.Finance

Orbiter Finance is another cross-chain bridge I started using last year. I was looking for a platform to move funds from BSC/Polygon to ZkSync Mainnet, but could not find one until I discovered Orbiter.Finance. The platform’s sophisticated technology facilitates the seamless exchange of assets belonging natively to the Ethereum network, with a strong emphasis on maintaining decentralization and security. With its inception in 2021, the project has rapidly gained traction and garnered a significant user base consisting of a diverse set of individuals and organizations.

Orbiter finance

In November 2022, a time of great uncertainty and volatility in the industry, Orbiter Finance completed its first-ever funding round, raising a substantial amount of capital from investors such as Tiger Global, A&T Capital, Starkware, Cobo Ventures, and Mask Network. The project also received support from Vitalik Buterin, the creator of Ethereum, who contributed a generous sum of 16 ETH to the endeavor. This influx of funding undoubtedly provided Orbiter Finance with the resources it needed to continue its growth and development in the future.

The use of a layer 2 mechanism in the protocol helps to minimize safety concerns and the accompanying risks associated with traditional layer 1 software. Presently, Orbiter provides support for a vast array of blockchain networks, enabling users to carry out asset trades very easily. These networks comprise Ethereum, StarkNet, zkSync, Loopring, Arbitrum, Arbitrum Nova, Optimism, Polygon, BNB Chain, ZKSpace, Immutable X, dYdX, Metis and Boba..

Orbiter Finance is renowned for its exceptional speed and economical pricing of transactions. The platform facilitates two crucial functions, namely the Maker and the Sender. The Orbiter’s official documentation elucidates the “Maker” as a cross-rollup service provider for the “Sender”. The Maker must deposit a surplus margin to the Orbiter’s contract before qualifying for the position. “In the usual process, the ‘Sender’ sends assets to the ‘Maker’ on the ‘Source Network’, and the ‘Maker’ sends back to the ‘Sender’ on the ‘Destination Network’”.

Orbiter.Finance is the crypto bridge that I use to move funds to the ZkSync blockchain.

Allbridge

The Allbridge platform is a simplistic, user-friendly, and trustworthy method for the easy exchange of digital assets across diverse networks. It serves as a gateway between non-EVM-compatible chains (such as Terra or Solana) and EVM-compatible chains (such as Ethereum, Polygon, and Binance Smart Chain) while also providing support for layer 2 solutions (such as Arbitrum, and Optimism). The goal of Allbridge is to abolish the barriers between blockchain networks and deliver a means for hassle-free cross-network asset movements.

Allbridge Core

Allbridge facilitates the transfer of cryptocurrencies, digital assets, and tokens and intends to expand its range to include NFTs as well. The platform offers a diverse set of transfer options, allowing users to send Native or Wrapped tokens from the source network and receive Native or Wrapped tokens on the destination network. In addition, Allbridge supports cross-chain swaps, ensuring a seamless and secure transfer experience for its users.

In every transfer process facilitated by Allbridge, two transactions are required, one on the source blockchain, and the other on the destination chain. The duration of the transfer largely depends on the confirmation time of the respective blockchain used. In the case of Allbridge, the platform ensures that the transaction speed is optimized to enable swift and efficient transfers. Therefore, if the confirmation speed of the blockchain used is rapid enough, the transfer can be completed within a matter of seconds.

Allbridge’s flexible fee structure enables stalkers to reduce the charge of moving assets between different blockchains. By staking on the source blockchain, users can lower the bridge fee, which is settled before the actual trade. This dynamic fee system ensures that users have greater control over their transaction costs and can optimize their use of the platform.

Having made its debut in 2021, Allbridge has facilitated a bridge worth a staggering 6.4 billion US dollars to date. The platform boasts a range of products, such as the Allbridge Classic (a cross-chain bridging solution), Allbridge BaaS (a white-label bridging solution), and the Allbridge Core (a cross-chain stablecoin swap platform). Allbridge has also been supported by several leading names in the blockchain industry.

If you are looking to move funds between EVM and non-EVM chains, Allbridge is your best bet.

Synapse

The cross-chain network, Synapse, is a highly popular, versatile, and secure communication platform established across chains. The network allows the integration of blockchains by providing a messaging system that facilitates the transfer of smart contract calls, tokens, and other data. Developers can utilize Synapse to create cross-chain applications such as cross-chain margining approaches, yield aggregators, markets for derivatives, and lending protocols.

The network is composed of a cross-chain communication system and a consensus mechanism that ensures the security of transactions. Hence with Synapse, the interoperability between blockchains is both seamless and secure. The messaging infrastructure established by the platform is designed to function on a wide range of blockchain networks. The platform’s versatility allows developers to transfer a variety of data types between chains, including contract calls, NFTs, snapshots, etc

Its security model is based on the Optimistic prototype which guarantees that cross-chain transmissions will remain secure. According to their official docs, “Smart contracts from one chain use the Synapse Messaging Router to send the message to the destination chain, where a corresponding Messaging Router sends it to the destination contract. Messages are optimistically verified to ensure security and trustlessness.”

Synapse provides a straightforward method to swap assets using their AMM liquidity pools that are cross-chain compatible. The platform provides comprehensive backing for more than 16 EVM and non-EVM blockchains and is working towards developing new integrations regularly. It is also an ideal platform for developers as it offers an easy way to incorporate a token-bridging system that can work across networks, natively into their decentralized application.

Synapse has successfully handled a plethora of transactions with tens of billions in bridged funds processed since its inception. Its TVL stands at an impressive 259,006,010 dollars with a volume of 39.1 billion dollars. Moreover, Synapse prides itself on recording 7.06 million transactions to date, while its unique addresses amount to 1.29 Million. Additionally, it has collected a staggering 23.23 Million dollars in fees.

SYN token is an essential element of the Synapse network, with a wide range of use cases. The token serves as a reward for users who provide liquidity on the platform, as well as for those who vote on critical community governance issues. As the network’s native token, it is utilized for paying transaction fees and facilitates smooth cross-chain communication while ensuring maximum security and transparency.

Synapse is one such cross-chain bridge that offers a wide range of blockchains for multi-chain transfers.

Hop Bridge

Hop protocol

Hop is an advanced rollup-to-rollup token bridge that facilitates scalable cross-chain transfers between different rollups and sidechains in real time, circumventing the network’s cumbersome challenge period. The platform relies on Bonders, who provide liquidity on the destination chain in exchange for a modest charge, to make this possible. The platform’s liquidity is dynamically adjusted and maintained through a sophisticated rebalancing mechanism that is fueled by these Bonders that operate decentralized nodes. These Bonders monitor state transitions on the source chain to verify the accuracy of transfers and assess whether to “bond” the transaction by shutting 110% of the transferred amount as collateral.

The Bonder extends a line of credit to users through hTokens, which are exchanged for their native token equivalent via an Automated Market Maker (AMM) on the receiving network. This process enables users to transfer tokens smoothly between networks. The hTokens have been developed to enable the protocol to create and destroy tokens automatically for easy transfer across different chains. This also helps in reducing the time taken to exit a particular scaling solution and enhances the capital efficiency of Bonders. Moreover, Bonders can release their fronted capital every 24 hours, thereby ensuring timely and secure transfer of tokens.

Hop’s designers were uncompromising in their commitment to security, creating a system with no weak points or trusted off-chain participants. Instead, the security is derived entirely from on-chain mechanisms. Individuals are provided with assurances on-chain that they will obtain their funds, even if Bonders are unavailable. In the unlikely occurrence that this happens, individuals must wait for the on-chain proof to be disseminated to the destination chain to manually withdraw their tokens. In the most adverse scenario, individuals may experience a delay, but their funds remain safe from the Hop Bridge.

I recently used Hop Bridge to move funds from any Polygon to the Base chain.

Portal Bridge

Portal Bridge, developed by Wormhole, functions as an advanced cross-chain transfer solution for both tokens and NFTs. Its unique feature lies in its ability to facilitate seamless transfers across various blockchains without the need for double wrapping, a common limitation in similar platforms. This streamlined process ensures that users do not have to reverse their transactions.

Furthermore, utilizing Portal Bridge for asset transfers, particularly from Ethereum to the Solana blockchain, may qualify users for potential Wormhole token airdrops. This is due to the system’s design to acknowledge and reward retroactive activity.

My recent experience with Portal Bridge involved transferring funds from Ethereum to Solana, strategically positioning myself to capitalize on forthcoming airdrop opportunities within the Solana ecosystem.
