Understand What Cross-Chain Bridges Are And How They Work

Cryptocurrencies are becoming increasingly popular, and the world is quickly adapting to this novel form of digital currency.

But the technology behind these digital assets can be confusing, especially when transferring cryptocurrencies between different networks, which is why cross-chain bridges are becoming more common.

Cross-chain bridges are a way to readily transfer digital assets from one blockchain to another, allowing users to take advantage of different networks and services for their digital asset needs.

In this article, we’ll discuss what cross-chain bridges are, how they work, alongside the benefits and potential drawbacks of using them.

What are Cross-Chain Bridges?

Cross-chain bridges are a simple tool used to transfer cryptocurrencies. They act as channels that allow users to move their digital assets and tokens. These bridges do not need centralized exchanges or intermediaries.

But, it operates by locking the assets of one blockchain network and issuing corresponding tokens on the destination network. Once this transaction is complete, the token can be exchanged.

How Do Cross-Chain Bridges Work?

Cross-chain bridges create a system of smart contracts which can run on multiple blockchain networks. These contracts serve as a bridge allowing users to transfer digital assets.

Transferring digital assets between different blockchain networks using cross-chain bridges involves several steps. These steps are:


The transfer starts with locking the digital assets on the original network. Locking is done by sending the assets to a specific address on the original network, controlled by the cross-chain bridge.

Issuing Tokens

Once the digital assets are locked, the cross-chain bridge creates corresponding tokens on the destination network, representing the same value as the locked assets.


The tokens are transferred to the destination network, where they can be redeemed for the original digital assets.


Once the tokens are received, they are redeemed for the original digital assets. The cross-chain bridge will release the locked assets back to the original owner.

Advantages of Cross-Chain Bridges

The cross-chain bridges are famous for a lot of perks. Some of them are;

  • Interoperability - Allows users to transfer digital assets between them.
  • Decentralization - No need for third parties.
  • Security - Operate using smart contracts which are secured by cryptography.
  • Efficiency - Allows users to transfer digital assets between different blockchain networks quickly and at a low cost.

What digital assets provide cross-chain bridges?

No particular coin or network is required for cross-chain bridges to function. If designed by skilled tech guys, any blockchain network will be interoperable with them!

Different blockchain networks are compatible with a cross-chain bridge.

If the software is made to be interoperable with all blockchains, cross-chain bridges can communicate with them.

Are chain-crossing bridges secure?

Cross-chain bridge is a software application constructed on top of other blockchains. Thus, just like other blockchain applications, cross-chain bridges are safe. However, they are a bit vulnerable to hackers if there is a loophole in either the blockchain software or the smart contract.

Cross-chain bridges play an exceptional role in the growing cryptocurrency ecosystem. They unite the blockchain system, helping users take full advantage of digital tokens and assets.
