Developing a Cross-Chain Lending Platform on Axelar

Developing a Cross-Chain Lending Platform on Axelar

The DeFi ecosystem is rapidly evolving, with innovative solutions continuously emerging to address scalability and interoperability challenges. As the demand for cross-chain services grows, the need for a unified, seamless platform becomes more pressing. Cross-chain lending is one such service that allows users to borrow and lend assets across different blockchains, facilitating better capital efficiency and a broader range of asset utilization. The TVL in DeFi surpassed $50 billion in 2024, with cross-chain protocols contributing significantly to this growth. This demonstrates the increasing appetite for interconnected DeFi solutions, opening up opportunities for new platforms to capitalize on this trend.

Axelar, a decentralized interoperability network, stands at the forefront of enabling cross-chain communication and bridging multiple blockchain ecosystems. By providing a reliable and scalable infrastructure, Axelar allows developers to build powerful cross-chain applications, such as lending platforms, with ease. 

Notable examples of cross-chain lending platforms utilizing Axelar include Kalkulus Finance and Midas Lending, both of which leverage Axelar’s interoperability to facilitate lending and borrowing across different blockchain networks. 

This blog will guide you through the development process of building a cross-chain lending platform on Axelar, covering key aspects from smart contract deployment to ensuring liquidity across chains. Let’s begin!

Understanding Cross-Chain DeFi and Its Growing Significance

Cross-chain DeFi represents a critical evolution in the DeFi ecosystem, enabling decentralized financial applications to operate seamlessly across multiple blockchain networks. To better understand cross-chain DeFi, imagine each blockchain as a unique TV network with its shows and content. Typically, viewers would need separate subscriptions to access content from different networks. 

Cross-chain DeFi acts as a “streaming aggregator,” offering users access to multiple blockchains from a single interface, eliminating the need for separate interactions with each network. This simplifies engagement with decentralized financial services across a variety of platforms, improving both accessibility and user experience.

Security Concerns of Cross-Chain DeFi

Cross-chain DeFi offers greater liquidity and access, but it also comes with significant security concerns. One of the biggest risks is the vulnerabilities in cross-chain bridges that facilitate asset transfers between blockchains. These bridges have become prime targets for hackers.

Security Concerns of Cross-Chain DeFi

Notable breaches include:

  • Ronin Network (2022): A $600 million loss due to weaknesses in the bridge’s centralized structure and validation protocols.
  • Wormhole (2022): Attackers exploited the Wormhole bridge for $300 million, taking advantage of flawed smart contracts.
  • Nomad (2022): A $190 million loss due to a code flaw, allowing multiple users to exploit the system simultaneously.
  • Binance Smart Chain (2022): A hack resulted in a $100 million loss and halted transactions, highlighting bridge infrastructure vulnerabilities.

These high-profile breaches underline the importance of improving security protocols and code audits to avoid future exploits. But security isn’t the only challenge facing cross-chain DeFi.

Scalability Issues

As DeFi grows, handling a higher volume of transactions across chains is becoming more difficult. This leads to congestion, slower transactions, and higher fees. Solutions like sharding and layer-2 scaling are being explored, but they are still developing.

Security Concerns

With multiple blockchains integrated, new risks arise, such as double-spending and unauthorized access. Cross-chain bridges, acting as intermediaries, are particularly vulnerable to attacks. Strong encryption, secure consensus mechanisms, and constant monitoring are crucial to preventing these issues.

Interoperability Challenges

While cross-chain interoperability has come a long way, fully seamless and secure asset and data transfers between different blockchains remain tough. Each blockchain has its own nuances, and achieving a standardized approach requires collaboration between developers and protocols.

The Need for a Cross-Chain Lending Platform Built on Axelar 

A cross-chain lending platform built on Axelar can address key challenges in DeFi’s security, scalability, and interoperability. Here’s how Axelar can help:

The Need for a Cross-Chain Lending Platform Built on Axelar 

Enhanced Security

Axelar provides a decentralized interoperability network that securely connects different blockchains. It uses threshold cryptography and multi-signature mechanisms to ensure safe asset transfers, mitigating risks from traditional cross-chain bridges that are prone to hacking.

Seamless Cross-Chain Interoperability

Axelar allows cross-chain communication without the need for custom integrations with each blockchain. This enables lending platforms to tap into diverse liquidity pools across various blockchains like Ethereum, Binance Smart Chain, and others, making it easier for users to borrow and lend assets.

Scalability

Axelar’s hub-and-spoke model ensures the platform can scale efficiently without congestion. This is crucial for a growing lending platform that needs to handle increasing transactions while maintaining performance and low fees.

Cost Efficiency

By removing the need for intermediary bridges, Axelar enables direct cross-chain transfers, reducing transaction costs and improving transaction speed. This lowers borrowing and lending fees for users, making the platform more affordable.

Risk Mitigation

Axelar enables cross-chain diversification, allowing lending platforms to access assets from multiple blockchains. This reduces dependency on any single chain and helps mitigate risks like network congestion or security vulnerabilities.

Key Market Takeaways for Cross-Chain Lending Platform

According to Gminsights, the blockchain interoperability market is booming! It was valued at $275.5 million in 2022 and is expected to grow rapidly at a CAGR of 26.8%, reaching around $2.88 billion by 2032. This growth is mainly driven by the rising demand for cross-chain asset transfers, which are becoming essential for businesses that operate on multiple blockchain networks.

As more companies explore the unique benefits of different blockchains, the need for seamless communication and interoperability is becoming a key focus. This, in turn, supports smoother asset transfers and boosts the overall efficiency of decentralized applications and DeFi platforms.

One example of this trend is the growing number of partnerships and integrations in the cross-chain lending space. 

For instance, in early 2023, Aave teamed up with Cosmos Hub to enable cross-chain lending and borrowing. This integration allows users to deposit and borrow assets on Cosmos Hub, offering lower transaction fees compared to Ethereum. 

Similarly, Uniswap’s integration with Polygon will enable users to trade assets across Ethereum and Polygon without the hefty gas fees, making cross-chain transactions more accessible. These partnerships not only increase liquidity but also expand the variety of assets available for lending and borrowing across different blockchain networks.
