Across Protocol's Positioning and Significance

In 2022, the Across Protocol team launched Across Protocol (ACX), aiming to solve inefficiencies in cross-chain transactions and capital utilization.

As a cross-chain bridge optimized for Optimistic Rollup L2 solutions, Across Protocol plays a crucial role in the DeFi and cross-chain interoperability sectors.

As of 2025, Across Protocol has become an important infrastructure in the Ethereum L2 ecosystem, with an active developer community. This article will delve into its technical architecture, market performance, and future potential.

Origins and Development History

Birth Background

Across Protocol was created by the Across team in 2022 to address the inefficiencies and high costs associated with cross-chain transactions, particularly for Optimistic Rollup L2 solutions.

It was born in the context of growing demand for scalable blockchain solutions and interoperability between different networks. The goal was to optimize capital efficiency through innovative liquidity management and competitive relayer dynamics.

Across Protocol's launch brought new possibilities for users and developers in the Ethereum ecosystem, particularly those working with L2 solutions.

Important Milestones

• 2022: Mainnet launch, achieving efficient cross-chain transfers with a single liquidity pool.
• 2023: Major upgrade introducing improved relayer mechanics and governance features.
• 2024: Adoption by several major DeFi protocols, pushing the price to new highs.
• 2025: Ecosystem expansion, with the number of integrated L2 solutions and DeFi applications surpassing 50.

With support from its community and development team, Across Protocol continues to optimize its technology, security, and real-world applications.

How Does Across Protocol Work?

Decentralized Control

Across Protocol operates on a network of decentralized nodes, eliminating the need for centralized control by banks or governments.

These nodes collaborate to validate transactions, ensuring system transparency and attack resistance, empowering users with greater autonomy and enhancing network resilience.

Blockchain Core

Across Protocol's infrastructure is built on top of Ethereum and various L2 networks, leveraging their security and transparency.

Transactions are recorded on these underlying blockchains, ensuring immutability and public verifiability.

The protocol's unique single liquidity pool design and competitive relayer model further enhance performance and capital efficiency.

Ensuring Fairness

Across Protocol uses a competitive relayer system to validate and execute cross-chain transactions.

Relayers compete to fulfill user requests, incentivized by fees and protocol rewards. This system ensures efficient and fair transaction processing.

Its innovation includes optimized capital efficiency and a no-slippage fee model.

Secure Transactions

Across Protocol utilizes advanced cryptographic techniques to secure transactions:

• Smart contracts ensure the integrity of cross-chain transfers
• Relayer bonds provide economic security against misbehavior

This mechanism ensures fund safety while maintaining transaction transparency.

Additional security features include time-locked recoveries and upgradeable contracts for future improvements.
