What is Across Protocol (ACX)?
Across Protocol is a decentralized cross-chain bridge designed to facilitate the movement of assets between Ethereum and various Layer 2 networks. It distinguishes itself from traditional bridging solutions through an intent-based architecture, which focuses on user outcomes rather than complex technical execution paths. At its core, the protocol operates using a network of competitive relayers who fulfill user requests almost instantly. When a user initiates a transfer, a relayer provides the funds on the destination chain immediately, effectively taking on the short-term risk of the transaction. The relayer is then reimbursed through a central liquidity pool after the transaction is verified. This model significantly reduces wait times, often completing transfers in a matter of minutes. The security of Across Protocol is underpinned by an optimistic verification mechanism provided by the UMA optimistic oracle. This system assumes that all transactions are valid by default but allows for a challenge window during which anyone can dispute a fraudulent claim. If a dispute occurs, UMA token holders resolve the conflict through a decentralized voting process. This optimistic approach minimizes the need for heavy on-chain computation, resulting in lower network fees and greater efficiency. Capital efficiency is another key pillar of the project. Unlike many bridges that fragment liquidity across multiple chains, Across utilizes a single liquidity pool located on the Ethereum mainnet. This design allows the protocol to manage assets more effectively and reduces the amount of idle capital required to support cross-chain transfers. The ACX token serves as the native governance and utility token for the ecosystem. Holders of ACX can participate in the decentralized autonomous organization known as the Across DAO. This governance body is responsible for making critical decisions regarding the protocol, such as adjusting fee structures, managing the treasury, and voting on future upgrades or integrations with new blockchain networks. The protocol supports a wide array of networks, including major Ethereum Layer 2 solutions like Arbitrum, Optimism, Polygon, and Base. Recent developments have also seen the protocol expanding its reach to non-EVM chains, such as Solana, by incorporating zero-knowledge proofs to maintain its security standards. By prioritizing speed, security, and capital efficiency, Across Protocol aims to serve as a fundamental layer for interoperability in the evolving multi-chain Web3 landscape. Learn more

Across Protocol (ACX) FAQ
Unlike traditional bridges that typically use 'wrapped tokens' or 'lock-and-mint' models, Across Protocol utilizes an 'intents-based' architecture. Users broadcast an 'intent' for a desired asset on a specific chain, and a network of relayers competes to fulfill this intent instantly using their own liquidity. Relayers are subsequently reimbursed on Ethereum L1 after UMA’s Optimistic Oracle verifies the transaction, ensuring rapid transfers while maintaining robust security.
UMA's Optimistic Oracle serves as the crucial security layer for Across Protocol. Its primary function is to verify that relayers have accurately provided the requested funds to users on the destination chain. This optimistic verification mechanism allows for extremely fast bridge transfers, often completed within minutes, while ensuring that the underlying security guarantees are equivalent to those of Ethereum L1.
The ACX token provides several key utilities. It grants holders significant governance rights, allowing them to vote on critical protocol parameters, fee structures, and treasury management decisions. ACX also acts as an incentive mechanism, rewarding Liquidity Providers (LPs) and relayers for their participation. Furthermore, users can stake ACX or provide liquidity to earn yield derived from the protocol's operational fees, fostering a vibrant and engaged ecosystem.
Yes, there is. Following a significant community discussion, a proposal was passed to permanently cap the supply of ACX tokens at 1 billion. This decision included renouncing the ability for the protocol to mint any additional tokens, ensuring a fixed and predictable supply for the long term. This provides clarity and stability regarding the total tokenomics of ACX.
Yes, Across Protocol has maintained a clean security record since its launch. As of early 2025, the protocol has processed a substantial volume of transfers without experiencing a single exploit or hack. This strong track record is a key differentiator and a significant point of confidence for its community, especially in an industry where many bridging solutions have faced security challenges.
Across V4 represents a major advancement, introducing Zero-Knowledge Proofs (ZKPs) powered by Succinct Labs. This innovation is crucial for expanding Across Protocol's reach beyond EVM-compatible chains. V4 enables the protocol to support non-EVM chains, such as Solana, without the need for bespoke, chain-specific adapters, thus streamlining new integrations and positioning Across as a versatile cross-chain solution for a broader range of blockchain ecosystems.
