Cross-Chain Technologies: Bridging the Gap in Blockchain Networks

As blockchain technology continues to grow and diversify, the importance of cross-chain technologies, particularly multichain bridges, cannot be overstated. These cutting-edge solutions are designed to enable users to move their digital assets seamlessly between different blockchain networks, such as transferring Ethereum (ETH) to Binance Coin (BNB) or Bitcoin (BTC) to Cardano (ADA). With the advent and expansion of multichain bridges, innovative projects like Multichain, Poly Network, and Orbit Bridge have emerged, each providing their distinct approach to cross-chain communication and collaboration.

Understanding Cross-Chain Technologies

At its core, a cross-chain technology aims to solve the problem of interoperability between different blockchain networks. As various networks have unique consensus mechanisms, smart contract capabilities, and transaction models, communication and asset transfer between them can be challenging. Cross-chain technologies bridge this gap by enabling transactions and data sharing across multiple networks, fostering a more integrated and efficient blockchain ecosystem.

Multichain Bridges: How They Work

Multichain bridges employ a combination of smart contracts, validators, and sometimes, dedicated nodes to facilitate cross-chain transactions. When a user wants to transfer assets from one blockchain to another, the process typically involves:

  1. Locking the assets on the source blockchain: The user locks the original assets in a smart contract on the source network. These locked assets serve as collateral for the equivalent tokens issued on the destination network.  
  2. Issuing equivalent tokens on the destination blockchain: The bridge creates and issues an equivalent amount of tokens on the destination network, backed by the locked assets on the source network.  
  3. Redeeming and unlocking: When the user wants to move the assets back to the source network, they burn the equivalent tokens on the destination network. The bridge then unlocks the original assets on the source network and releases them back to the user.

The Pros and Cons of Cross-Chain Technologies


  • Enhanced interoperability: Cross-chain bridges enable different blockchain networks to communicate with each other, creating a more interconnected and efficient ecosystem.
  • Greater accessibility: With cross-chain solutions, users can access a broader range of DeFi applications, regardless of their native blockchain.
  • Increased liquidity: Cross-chain bridges facilitate the movement of assets between networks, resulting in improved liquidity and more opportunities for traders.


  • Security risks: As demonstrated by the Ronin, Poly Network, Binance Bridge, and Wormhole hacks, cross-chain bridges can be vulnerable to exploits and cyber-attacks, leading to substantial financial losses.
  • Complexity: Implementing cross-chain solutions can be technically challenging, often requiring deep knowledge of multiple blockchain protocols.
  • Scalability concerns: As the number of cross-chain transactions increases, it can lead to congestion and slower transaction times on some networks.

FAQ about Cross-Chain Bridges


Source: DefiLlama

  • Q1: What is a multi-chain bridge?

A: A multi-chain bridge is a technology that allows users to transfer digital assets between different blockchain networks seamlessly. This enhances interoperability and provides access to a wider range of DeFi applications.

  • Q2: How does a multi-chain bridge work?

A: Multi-chain bridges work by locking assets on one blockchain and issuing equivalent tokens on another. This process usually involves smart contracts and validators to ensure the secure transfer of assets between networks.

  • Q3: What is the difference between cross-chain bridge and multi-chain?

A: While both terms are often used interchangeably, a cross-chain bridge typically refers to a specific solution connecting two blockchains, whereas multichain is a broader term encompassing any technology that enables communication between multiple blockchain networks.

  • Q4: Are cross-chain bridges safe?

A: While cross-chain bridges have enhanced the DeFi ecosystem’s interoperability and accessibility, they can also be vulnerable to exploits and cyber-attacks. The safety of a cross-chain bridge depends on its underlying technology, security measures, and the competence of its developers.

  • Q5: What are the best cross-chain bridges?

A: Some of the most prominent cross-chain bridges, ranked by total value locked and with more than two chains integrated, include:

  1. Multichain: $1.55 billion
  2. Poly Network: $330.29 million
  3. Portal: $275.98 million
  4. Synapse: $187.05 million
  5. ChainPort: $185.96 million
  6. Orbit Bridge: $181.73 million
  7. cBridge: $141.99 million
  8. Axelar: $90.12 million
