Digital assets are typically restricted to their native blockchain networks, and existing methods of transferring tokens from one blockchain network to another are highly vulnerable to hacking or involve using a trusted third party.
However, multichain tokens enable users to transfer their assets to another blockchain directly without giving up custody of their tokens.
Experts in the blockchain space believe that cross-chain tokens can positively impact the industry by enabling greater user participation over multiple networks.
Marius Ciortan, director of product engineering at Bitpanda and Pantos, a European crypto exchange, told Cointelegraph, “Multichain tokens can establish a more fluid and connected environment in the context of decentralized finance.”
Ciortan continued, “Multichain tokens, for example, can aid in developing more efficient decentralized exchanges by allowing users to trade assets across several blockchain networks. This can aid in improving liquidity and decreasing fragmentation in the DeFi ecosystem.”
Multichain tokens can also help connect blockchain networks, assisting developers in deploying their applications on multiple blockchains. Hoon Kim, chief technology officer at Astar Foundation, a layer-1 smart contract platform, agreed, telling Cointelegraph, “More asset and liquidity interoperability means more interdependence between ecosystems. This can expand the network to allow more innovation and increase the risk of failure when one asset loses its value.”
“But if an asset wants to increase its demand, we can see a future where more and more projects will aim to inject their assets into multiple networks and increase their utility,” Kim said.
Challenges with interoperability
Facilitating communication and interoperability among various blockchain networks heavily relies on interoperability protocols. However, interoperability protocols in the blockchain domain present several challenges that require resolution in order to ensure the seamless operation of the blockchain ecosystem.
The absence of standardization poses a significant obstacle to interoperability protocols. There are many different exchange protocols, and each one has a different design and framework. This means that the environment is full of different networks that don’t work together.
Since there isn’t much unity, it’s hard for developers to make apps that can run on different blockchain networks and still work. Because of this, people who work in software development have to learn how to use different exchange standards, which can take a lot of time.
Scalability is another obstacle to interoperability protocols. Most interoperability protocols are specifically engineered to manage a restricted quantity of transactions, potentially impeding the flow of data in networks that experience high traffic levels.
As a result, the issue of scalability may lead to sluggish transaction processing, elevated fees and network overcrowding.

To tackle this challenge, it is imperative to devise interoperability protocols capable of managing large quantities of transactions and expanding proportionately with the increasing adoption of blockchain technology.
Security is another noteworthy obstacle for interoperability protocols. The interconnectivity of blockchain networks is associated with an elevated likelihood of security breaches and hacks. The absence of security considerations during the design of an interoperability protocol can lead to exploitable vulnerabilities of which malevolent entities can take advantage.
Developers have stressed that it is imperative to design interoperability protocols with resilient security characteristics capable of safeguarding against potential attacks and upholding the authenticity of the blockchain ecosystem.
Ciortan said, “One of the biggest challenges we have seen across all interoperability projects in recent years is ensuring the system’s security. Validation of events across multiple chains is a difficult task, and it takes a lot of work and research to develop a system that is robust enough to achieve this goal reliably and can stand the test of time.”
The challenge of addressing the complexity of interoperability protocols is a crucial matter that warrants attention. The intricacy of interoperability protocols necessitates a profound comprehension of cryptography, networking and distributed systems.
To get around these problems, the blockchain community has to work together to develop standards and best practices for interoperability protocols.
Kim also believes security is one of the major challenges concerning interoperability in the blockchain space. Kim said:
“Most bridge protocols are managed through a centralized server that facilitates a burn-and-mint function where the account is controlled via a multi-sig. But recently, we’ve been seeing a lot of ‘layer 0’ protocols with node…
