A few years back sending assets from one blockchain to another was impossible. But today this imagination has become reality. With blockchain bridges, developers and other blockchain users can easily share their assets from one blockchain to another. But first, let’s just understand what blockchain bridges are and how blockchain bridges work?
What are blockchain bridges?
A blockchain bridge is a great invention that solves the main pain points within blockchains – lack of interoperability. It is a tool that helps you to transfer assets from one blockchain to another. Since blockchain assets are often not compatible with one another, blockchain bridges create synthetic derivatives that represent an asset from another blockchain. For instance, if you use a bridge to send one Sol coin to an Ethereum wallet, in this case, the Ethereum wallet would receive a "bridge" version of Solana that has been converted to an ERC-20 token – the generic token standard for fungible tokens on Ethereum.
How do blockchain bridges work?
Now that you know what blockchain bridges are, it's time to understand how do blockchain bridges work? Bridges in blockchain operate by facilitating the interaction of smart contracts or protocols across multiple blockchains, enabling the seamless transfer of assets and data between these blockchains. This functionality ensures enhanced transparency, security, and interoperability. Here's a breakdown of its mechanics:
To initiate a bridge transaction, assets are locked on the source blockchain. This locking process generates a cryptographic proof that certifies the assets' ownership.
Once locked, the bridge protocol generates equivalent tokens on the destination blockchain. These tokens represent the locked assets and are issued to the user's wallet on the target blockchain.
The bridge smart contract on the source blockchain verifies the locked assets and the issuance of equivalent tokens. Similarly, the smart contract on the destination blockchain ensures that the equivalent tokens correspond to the locked assets.
Bridge protocols also handle the exchange of data between blockchains, enabling secure sharing of information, particularly for cross-chain communication scenarios.
Some advanced bridges offer bi-directional functionality, allowing assets and data to flow back and forth between the connected blockchains.
Benefits and Use Cases of blockchain bridges
Bridges break down the barriers that isolated blockchains often face, enabling them to work harmoniously and share resources.
Cross-chain bridges facilitate the transfer of assets from one blockchain to another. For instance, you can move Ethereum-based tokens to a BSC-based network.
Decentralized Finance (DeFi)
Bridges enhance liquidity by enabling assets to move fluidly between different DeFi platforms and ecosystems.
Developers can create decentralized applications that interact with multiple blockchains, offering users a seamless experience.
Bridges can mitigate network congestion by allowing transactions to be processed on different blockchains.
Blockchain bridges present groundbreaking solutions for interoperability, security, and decentralization. As these bridges continue to evolve, we're inching closer to a future where blockchains seamlessly collaborate, create harmony within data, transferring assets, and innovation across the decentralized landscape.
Get started by requesting an API key from expand.network for free. Once the user gets the API key they can use the Stargate bridge API endpoint to get any data they want from the blockchain. The available API are:
With this API, the user can read the balance of a particular token pair of an account.
With this API, the user can read the details of a transaction.
With this API, the user can swap the assets across multiple chains.
With this API, the user can loan the assets to the specified bridge.
With this API, the user can remove user liquidity across multiple chains.

In conclusion, blockchain bridges play a vital role as connectors in blockchain technology. They serve as links between disparate blockchain ecosystems, enabling the seamless transfer of assets and data across these networks. These bridges hold immense potential, not only for the cryptocurrency and decentralized finance (DeFi) sectors but also for the broader world of blockchain applications. They facilitate the movement of assets between different blockchains, opening up a realm of possibilities for cross-chain asset management, decentralized exchanges, and more.
However, it's crucial to approach blockchain bridges with caution. Security remains a paramount concern, as any vulnerabilities in a bridge can have far-reaching consequences. Trustworthy development, comprehensive auditing, and robust security measures are essential to ensure the safety and integrity of blockchain bridge operations.
