Create new frontiers with cross-chain DeFi technology


Omatech Web3


The application of blockchain technology, its use cases and underlying capabilities have driven revolutionary changes across many industries. Although most enterprises nowadays seem interested in reaping the benefit of blockchain-enabled, the finance sector is considered the early adopter of decentralization. Evolution in these technologies, DeFi, Crypto, and Web 3, significantly impacts the DeFi ecosystem, stimulating changes for it. Talking about the most recent buzz in the Defi world, we find cross-chain Defi technology as the frontier. Hence, Let’s discuss cross-chain technology and understand how it supports the growth of the existing DeFi infrastructure.


DeFi cross chain


Blockchain has enabled financial institutions to replace their centralized, legacy infrastructure with a robust peer-to-peer ecosystem, revolutionizing services such as banking processes, lending loans, digital asset trading, and execution of finance-related contracts.

DeFi is generally powered by blockchain and cryptography. However, industry leaders are now combining DeFi and Crypto with Web3 to provide enterprises with a more robust infrastructure to support the future of DeFi.

What is cross-chain technology?

The blockchain ecosystem inherently represents a siloed infrastructure that restricts the two non-native blockchain networks from communicating with each other. To address this interoperability challenge, cross-chain technology enables interoperability across independent blockchains, allowing two separate blockchains to interact and share resources and arbitrary data for various purposes.

The interoperability challenge was the most significant obstruction in the mass adoption of blockchain in many industries. Now that most third-generation blockchains are powered with cross-chain technology, their ecosystems support the development of novel dApps to support industry-specific use cases.

How does cross-chain technology work in DeFi?

DeFi Chuỗi chéo

DeFi has experienced exponential growth with the massive rise in crypto investments and more industries identifying the potential of decentralized technology. Since second-generation blockchains represent a siloed decentralized ecosystem, it created many challenges such as high transaction cost, inadequate liquidity and slow transaction execution, hampering the mass adoption of DeFi. As a solution, cross-chain technology showed up in the blockchain world.

As the name suggests, cross-chain DeFi technology is the solution to the DeFi ecosystem’s inability to facilitate multi-chain smart contract transactions, powering the ecosystems with interoperability elements. Innovation-rich web3.0 blockchain projects like Polkadot are optimized to facilitate interoperability between non-interoperable blockchain networks via parachains and their native bridges.

With more cross-chain technology-enabled blockchain networks being introduced, DeFi space facilitates higher interoperability that interconnects independent DeFi platforms, DeFi marketplaces, and DeFi dApps to support a low-cost yet efficient DeFi economy. With that, cross-chain DeFi allows users to access diverse DeFi platforms via single-point access.

Cross-chain DeFi offers inter-blockchain connectivity, enabling instant token swap across unique and isolated blockchains. For example, if you already have a good amount of Ether (the native currency of Ethereum) in your wallet, but you want to invest these tokens on a DeFi platform built on a blockchain other than Ethereum. You must use web 3.0 bridges like Polakdot bridges.

With interoperable bridges, users do not require a centralized exchange to convert their existing tokens into the currency of any desired blockchain network for further use. Instead, bridges allow the users to perform instant swaps that mint the token of an equivalent amount on the other blockchain whenever required.

Cross-chain DeFi vs Regular DeFi: key aspects compared


Cross-chain technology powers the DeFi ecosystem with interoperability, enabling them to benefit from the unique attributes of multiple Defi protocols. Cross-technology supports assets trading, lending and exchange across DeFi platforms on isolated chains.

This technology further brought a solution to enterprises, financial institutions, and businesses struggling to provide their users with a multichain experience, allowing them to move their financial assets seamlessly from one chain to another.


Since cross-chain DeFi technology allows the users to leverage the speed and efficiency of the multiple blockchain networks, it holds the potential to facilitate better scalability compared to siloed systems. For instance, individuals can use a dApp built on Ethereum while leveraging the high TPS and low transaction from a different blockchain protocol such as XDC Network.


With cross-chain DeFi, borrowers can shift their pledged financial digital assets from first-generation Bitcoin to second and third-generation blockchains such as Cardano, Ethereum, or Polkadot. Likewise, a lender can accept digital assets as loan security across multi chains. DeFi without cross-chain technology, on the other hand, limits the access and activities of both the lender and borrower to the specific blockchain protocol on which a specific DeFi platform runs.


Powered with interoperability, cross-chain DeFi ensures end-to-end transparency between various interconnected DeFi ecosystems. Higher clarity supports real-time independent auditing of the collaterals, reducing risks regarding potential fraudulent tactics and manipulation of fractional reserve rights. DeFi infrastructure without cross-chain elements cannot enable transparency, which remains limited to a particular ecosystem on which the DeFi solution is built and run.


Relying on a single blockchain for “on-chain” data storage can be expensive for many DeFi applications, and some decentralized networks even create trouble storing large files. However, a Defi ecosystem can extend its storage capacity by utilizing the space offered in the interoperable ecosystems.


Cross-chain technology enables the DeFi users to engage in micro-transfer approaches faster and more efficiently across evolving landscapes. This facility is highly relevant across industries such as blockchain gaming, e-commerce and brands.

What cross-chain DeFi platforms are relevant today?

Since cross-chain DeFi is the latest buzz, many interoperable and feature-rich DeFi platforms are being launched frequently. Following are some platforms that hold higher value across trading and finance industries.

Cross-chain DeFi Lending platform

Cross-chain DeFi lending platforms are powered with the latest technologies to help users manage their savings and supply & lock them for interest-earning across multiple chains. Being able to access and interact with multiple lending platforms, users can effectively manage their funds, lend loans to the interested users, and gain higher profit.

A cross-chain DeFi lending platform is unique. It is integrated with new-age features such as automated market maker (AMM) interoperable smart contracts, multichain Defi Wallet, atomic swap, liquidity pools, unified dashboard etc. Compared to a non-interoperable DeFi lending platform, cross-chain defi supports mass adoption of DeFi across industries such as gaming and e-commerce, where multichain transactions and trading is essential.

Cross-chain DeFi Staking platform

DeFi staking platforms enable users to make additional profit on their funds by locking a specified portion of the platform’s native token. However, DeFi staking is a means to become a validator in any proof-of-stake (POS) blockchain platform.

Powered with the interoperability element, a cross-chain DeFi staking platform supports staking on various unique blockchain ecosystems, not just a single blockchain network. It implies that users can become validators for multiple blockchains and raise profit from their contribution to those staking.

Cross-chain DeFi Exchange platform

With the cross-chain feature, a DeFi exchange platform enables the users to lend and borrow a wide range of crypto assets across multiple DeFi platforms running on independent chains. Being able to borrow or earn interest from different platforms seamlessly, users can get the best of staking their digital assets to maximize appeal and perform their duties as validators.

DAO-enabled cross-chain DeFi platform

New and futuristic DeFi projects that are being launched most recently are DAO-enabled. Regardless of the purposes a cross-chain DeFi platform intends to serve, which can be staking, liquidity, and decentralized exchange, DAO facilitates autonomy across the enterprise launching and managing the DeFi platform.

Users on DAO-based cross-chain DeFi platforms can invest, trade, and stake their digital assets without getting oppressed due to regulations imposed by a hierarchy-based centralized body.

How to create a cross-chain DeFi Platform?

Cross-chain DeFi solutions are optimized to enable interoperability for inter-blockchain transactions. For your DeFi project to be interoperable, you should develop and run it on a blockchain, which can originally provide interoperability to the dApps built on its ecosystem.

Building the cross-chain bridge requires setting up a brand new session with the visual code editor, writing and compiling the codes for the smart contract, and working on the user interfaces.
