Across Protocol (ACX)
The technology behind Across
UMA's optimistic oracle
The core technology that powers Across is UMA's optimistic oracle. This oracle system is a decentralized truth machine that allows for secure data verification across blockchain networks. It operates under the principle of optimistic verification, where data is assumed to be correct unless disputed. This approach allows the system to operate efficiently and quickly, as it does not require constant on-chain verification. By utilizing UMA's optimistic oracle, Across ensures that cross-chain transactions are both secure and reliable.

Capital efficiency
Across is optimized for capital efficiency, which means it is designed to use its resources in the most effective way possible. A single liquidity pool is central to this design, allowing for a consolidated source of funds that can be used to support transactions across multiple blockchains. This centralized liquidity helps minimize the capital required to facilitate cross-chain transfers, making the process more efficient and cost-effective for users.
Competitive relayer landscape
Another key component of Across is its competitive relayer landscape. Relayers are entities that facilitate the transfer of assets across different blockchain networks. Across encourages competition among relayers, which promotes better service and lower costs for users. This competitive environment ensures that transactions are processed quickly and efficiently, as relayers strive to provide the best possible service.
No-slippage fee model
Across adopts a no-slippage fee model, which is particularly advantageous for users conducting large transactions. Slippage refers to the difference between the expected price of a transaction and the actual price at which it is executed. By eliminating slippage, Across ensures that users receive the same value they expect from their transactions, providing a more predictable and transparent bridging experience.
Use cases of Across
Across can be used for a variety of applications within the cryptocurrency ecosystem. It is particularly useful for users who need to transfer assets between different blockchain networks, such as moving tokens from Ethereum to a Layer 2 solution or another compatible network. Developers can also leverage Across to build decentralized applications (dApps) that require cross-chain functionality, broadening the potential use cases for blockchain technology.
