In the explosive growth of the Ethereum ecosystem in new Layer 2 and Layer 3, what does "scalability" mean?

The answer is programmable interoperability.

Due to their poor user experience and security risks, cross-chain bridges have become a negative synonym for blockchain interoperability. However, a new generation of arbitrary message passing protocols has begun to change this perception - such as Chainlink CCIP, LayerZero, Wormhole, and Axelar's universal message passing.

Now, programmable interoperability becomes the next step in cross-chain narrative - at a critical moment when modular infrastructure like Celestia and Eigenlayer emerges, signaling a more decentralized Ethereum ecosystem. Having programmable interoperability means:

· Any user on an EVM chain can easily interact with any other on-chain applications and assets with just one click.

· The new EVM chain is easy to connect and has low development costs for developers, covering any consensus method (such as ZK proof).

These two requirements require more than just sorters and bridgers. Only a programmable interoperable layer can support L2-based extensions in Ethereum applications and blockchain ecosystems. Axelar has integrated with other key component sets used to extend the Ethereum ecosystem, such as Celestia, Eigenlayer, Lido, and Frax. These projects are working together to build a platform that enables this level of rapid and easy scalability for EVM-compatible applications and other applications.

What is Axelar?

Axelar is a programmable platform that connects blockchains. On the Axelar virtual machine, cross-chain functionality is automated and abstracted, creating a unified user and developer experience across multiple blockchains. This enables Web3 expansion similar to the SaaS components enabled in Web2.

· User abstraction - Through universal message transmission, applications can send any valid payload and trigger multiple function calls across chains, achieving a one-click user experience.

· Application developers abstraction - Inter-chain token services can automatically perform complex tasks involved in managing token supply across multiple chains.

· Blockchain Developer Summary - Interchain Amplifier automates new chain connections, providing immediate network effects and arbitrary interoperability.

With programmable interoperability, cross-chain connections become simple, seamless, and behind the scenes. Applications built on EVM L2 can be scaled to the entire Ethereum ecosystem. Developers can "build once, run anywhere."

Scale Architecture

Axelar connects to 56 blockchains, more than any other cross-chain network. Therefore, the double-sided connection method cannot effectively scale.

Interchain Amplifier will accelerate this advantage, allowing hundreds or even thousands of blockchains to connect quickly and easily.

The construction cost of cross-chain connections is high and cannot be reused. Interchain Amplifier eliminates this complexity for developers: the unified UX for cross-EVM chains is an out-of-the-box component of RaaS (Aggregation as a Service) and RDK (Aggregation Development Kit), which is suitable for building applications on new L2.

Only 100 blockchain is equivalent to about 4,950 potential connections.

For an ecosystem containing hundreds (not to mention thousands) of blockchains, a central hub-and-spoke topology is required. Each new connection immediately gains exclusive routing to any other connected chain via the shortest possible path.

「Web3 Kubernetes」

Axelar Virtual Machine (AVM) is a fully functional, Turing-complete state machine that provides a natively multi-chain programmable environment. It allows applications to provide a unified user experience across multiple chains with minimal developer overhead.

AVM has two main components:

· Interchain Amplifier allows developers to establish a connection with the Axelar network without permission. The ultimate result is scalable interchain technology that can adapt to the future development of the network layer.

· Interchain Maestro, allows developers to quickly scale with minimal overhead. Its motto is: Build once, run anywhere, like Kubernetes for Web3.

Recently, the first component of Interchain Maestro has been launched on the mainnet: Interchain Token Service (ITS), which can automatically create and manage Interchain tokens. These tokens can move across multiple chains and have native-like interchangeability and customizable features.
