Top 10 Cutting-Edge Blockchain Interoperability Projects in 2024

Blockchain interoperability refers to the ability of blockchains to communicate with each other, based on cross-chain data transmission protocols, allowing one blockchain to read and write the data of another blockchain. Today, Web 3.0 is developing in a multi-chain, multi-layered direction. Incomplete statistics show that there are over 100 Layer-1 blockchains (basic chains) and an increasing number of Layer-2 and Layer-3 networks based on Layer-1 chains.

Most blockchain networks today (L1, L2, L3) are not compatible with other blockchains but only with networks and applications within the same ecosystem (i.e., operating on the same basic blockchain). This leads to limited resources and fierce competition between different blockchains, instead of being able to collaborate and support each other’s development.

Therefore, Blockchain Interoperability was created to address these issues, making the blockchain industry more cohesive, enhancing cooperation, ease of use, and flexibility. It is no exaggeration to say that blockchain interoperability (Blockchain Interoperability) is the key to the development of Web3 in the future. If you are interested in this topic, this article will share with you a list of the 10 best Blockchain Interoperability platforms currently available for your reference.

Best 10 Blockchain Interoperability 2025

Polkadot (DOT)

Polkadot is becoming a specialized ecosystem aiming to provide interoperability and scalability across multiple independent blockchains (called parachains). Applications and services on it can communicate across chains, allowing true interoperability.

Parachains can communicate via Cross-Consensus Messaging (XCM). This is a new feature introduced by Polkadot in May 2022 to allow parachains in the ecosystem to easily interact and directly transfer data to each other.

Specific aspects supported by XCM include:

• Support for any data type, meaning not just cross-chain token transfers but also cross-chain applications.
• Programmability, meaning blockchains can be programmed with each other, a feature previously unheard of in blockchain technology.
• With cross-consensus, communication is possible between smart contracts on different virtual machines.

Currently, XCM has connected over 450 projects, and this number is rapidly increasing. Polkadot has continued to expand its ecosystem in the bear market and has been number one in developer activity over the last 6-12 months.

Router Protocol (ROUTE)

Router is a cross-chain liquidity aggregation platform designed to provide bridging infrastructure between current L1 and L2 blockchain solutions. Its goal is to allow users to seamlessly exchange assets from different networks in a near-instant and low-cost way. Built with Cosmos SDK, Router Protocol’s first main product will be a bridge between Polygon and Ethereum. Subsequently, it is gradually moving towards building bridges between various other blockchains like Binance Smart Chain, xDai Chain, Cardano, Algorand, Solana, Stellar, Polkadot.

Router Protocol is not just developed for end users but also as a platform allowing developers to build their products on it with features such as:

• Unified Gas Fees: Using a single payment medium for multi-chain transactions.
• Cross-chain Governance: Supporting user participation in governance across multiple chains.
• Best Price Discovery: Facilitating trading at the best prices connected from multiple DEXs.
• Unified Aggregator: Enabling communication and asset transfers between chains with ease.

Overall, the concept of Router Protocol is quite innovative as it can connect not only Layer 1 platforms with each other but also delve into supporting platforms on Layer 2. It is a Blockchain Interoperability worth paying attention to, though it has not attracted much attention currently.

Quant Network (QNT)

The mission of Quant is to unleash the power of blockchain for everyone by providing an interoperable ecosystem and real-world solutions. It aims to solve interoperability issues that have been a challenge for blockchain technology using Overledger and APIs. Overledger is the world’s first blockchain-agnostic API gateway facilitating true interoperability by connecting businesses publicly and privately with multiple distributed ledger networks.

The Quant ecosystem mainly consists of:

• Overledger Operating System
• Multi-chain Applications (mApps)
• Overledger Network Marketplace

Simply put, Quant connects blockchains, networks, enterprise systems and software, applications, and platforms, with the goal of integrating all blockchains into an easy-to-use operating system.

Although Quant Network focuses more on enterprise blockchain services, it is also working to integrate many cryptocurrency blockchains into its Overledger Network. Quant Network has supported Bitcoin, Ethereum, XRP, Binance Chain, Stellar, EOS, IOTA, and Constellation blockchains. Additionally, it supports JP Morgan’s Quorum blockchain, R3 Corda, and Hyperledger Fabric. Overall, this is one of the most promising Blockchain Interoperabilities at the moment.

Cosmos (ATOM)

Perhaps the most prominent Blockchain Interoperability currently is Cosmos. Cosmos focuses on expanding a network of independent blockchains connected through their IBC (Inter-Blockchain Communication) protocol, building an “Internet of Blockchains.”

The IBC protocol has two layers:

• One is the transport layer, providing infrastructure to ensure connectivity between chains and data verification.
• The second is the application layer, determining how data transmitted between chains is packaged and interpreted, primarily for building cross-chain applications such as token transfers, cross-chain accounts, NFT transfers, etc.

I am confident in stating that Cosmos is a very practical project, growing by focusing on cooperation and innovation rather than competition. In the future, real value will be captured as parties exchange, store, and secure without relying on centralized servers, and Cosmos excels in this regard.

Currently, Cosmos has over 272 applications and services in its ecosystem, and its vision is to connect over 1 million blockchain applications on over 1 million sovereign blockchains. Like Polkadot, Cosmos has continued to develop in the cryptocurrency market downturn and is consistently ranked in the top 5 protocols for developer activity.

Chainge Finance (CHNG)

Chainge aims to become the most liquid, cross-chain, and highly interoperable DEX aggregator. It is the only protocol that can aggregate liquidity from different chains simultaneously.

Unlike existing bridge projects, Chainge performs multiple cross-chain operations simultaneously through chain roaming. Through cross-chain roaming, users do not need to switch bridges between multiple platforms, access separate wallets, etc.

For the above functions, Chainge is mainly executed through Fusion DCRM. DCRM (Distributed Control Rights Management) is an encryption technology that facilitates the movement of digital assets in and out of the chain by building bridges between blockchains.

Currently, Chainge can support over 40 chains and more than 1,400 assets.

Constellation (DAG)

Constellation is redefining the interoperability of Web3 and Layer0 consensus. It offers a data-independent interoperable network capable of containing user-defined complex data types and supporting an unlimited number of state channels running on Layer 1.

Constellation democratizes existing digital infrastructure and functions as a global ledger, notary, and audit layer for all digital information and operations. It has developed core infrastructure (Hypergraph) for currency transactions and indexing for the network through its native DAG. It also establishes a programmable interface to build solutions, the so-called Layer0 standard, to combine concepts of data collection, exchange, and value transfer as well as transaction capabilities in an open network.

Constellation’s Hypergraph (HGTP) is a free decentralized network for verifying transactions, meaning a node can send a transaction to multiple nodes, which then broadcast the transaction across the network (not necessarily to all nodes).

Ferrum Network (FRM)

Ferrum Network is a high-speed interoperable network. It is built to focus on real-life financial applications and person-to-person transactions. They use DAG technology to accelerate the speed of digital asset transactions within the network to just a few milliseconds with low transaction costs.

When Polkadot demonstrated the necessity of a Heterogeneous Multi-chain Framework with impressive adoption, Ferrum also deployed itself as a parachain. Ferrum allows users to focus on their target audience, regardless of the core stack, consensus mechanism, or operating environment. It primarily addresses two issues:

• First, eliminating the need to hire many multi-language developers with expertise for each network.
• Second, developers do not need to invest time in learning new languages.

Additionally, as a developer, you don’t need to understand the specifics of each network because, with Ferrum, you can access each network and reach audiences from other networks.

Morpheus Network (MNW)

Morpheus is a supply chain middleware software platform, specializing in providing blockchain middleware solutions with over 100 functions that can appropriately integrate both traditional and emerging technologies.

The current key application aspects of Morpheus include:

• Executing automatic labor contracts based on smart contracts, besides shipping and customs documents, it also performs rapid international payments for over 1600 banks.
• Providing the ability to automate the supply chain based on new and existing technologies, such as using Ripple or FedEx tracking technology to indicate the appearance of consolidated shipments.

Loom Network (LOOM)

Loom Network is a developer-focused interoperable platform. It provides developers with multi-chain scalability to build user-centric DApps with high performance.

Loom offers seamless integration with Bitcoin, Ethereum, Binance Chain, Tron, and other blockchains. This provides developers with an all-in-one solution, as DApps built on Loom can be used simultaneously by users on various blockchains. Basechain, Loom’s main network, runs on Delegated Proof of Stake (DPoS). It is optimized for the fast transaction times and high throughput needed for real-world DApps.

The network’s native token, LOOM, is used by developers to pay for DApp hosting services on the network. Unlike other blockchains, with Loom, developers pay a fixed monthly fee to host their DApp, so users do not have to pay any transaction fees. Loom currently has the top 100 ERC20 tokens integrated into Basechain.

Wanchain (WAN)

Wanchain is a solution for blockchain interoperability that facilitates cross-chain activities through direct decentralized bridges. Its bridges allow seamless transfer of tokens and digital assets between blockchains.

Wanchain offers three different types of bridges:

• Direct Bridges: These bridges allow for the quick and secure transfer of digital assets from the source chain to the target chain without intermediaries or relay networks.
• Layer-2 Bridges: This type of bridge is used to connect assets between layer-2 networks. For example, users can connect assets between Polygon and Arbitrum while maintaining layer-2 features like low gas fees and high transactions per second (TPS).
• NFT Bridges: NFT bridges use the lock-mint-burn-unlock protocol. Moving an NFT from one blockchain to another requires the original NFT to be locked on the source chain. Then, a copy is created on the target chain with the NFT ID and attributes then transferred.

Wanchain is compatible with the Ethereum Virtual Machine (EVM), making it easy for developers to build cross-chain applications using Solidity. Currently, Wanchain can interact with 22 blockchains and 45 tokens.

This concludes the entire content shared about the most promising Blockchain Interoperability projects. Note, the list may not be complete, and it has been compiled based on personal opinion. There may be many other Blockchain Interoperability platforms worth considering beyond this list. Nonetheless, the potential of Blockchain Interoperability is undoubtedly significant. Therefore, you may want to further explore and choose one of them for long-term investment. Wishing you success.
