Across Protocol Integration with Solana via Rubic

A new integration with **Across Protocol** has been announced, expanding cross-chain bridging capabilities. Across Protocol offers a unique approach to blockchain bridging by combining: - Optimistic oracle technology - Bonded relayers for security - Single-sided liquidity pools This integration enables **instant transactions** from rollup chains to Ethereum mainnet in a decentralized manner. The protocol's novel architecture provides users with faster and more efficient cross-chain transfers compared to traditional bridging methods.

**Across Protocol** has released a new **Swap API** that allows developers to integrate cross-chain swapping functionality into their applications in just 30 seconds. The API simplifies the integration process by: - Providing instant swap capabilities across multiple chains - Reducing development time from hours to seconds - Offering seamless cross-chain transactions This launch builds on recent industry trends toward **faster swap execution**, with major platforms like Uniswap reporting 30% speed improvements in their mobile applications. The new API leverages Across Protocol's optimistic oracle system and bonded relayers to enable **decentralized instant transactions** between rollup chains and Ethereum mainnet. Developers can now add sophisticated cross-chain swap functionality without complex infrastructure setup or lengthy integration processes. [Learn more about the Swap API](across.to/blog/swap-api)

**Uniswap has integrated Across Protocol** to power its in-app cross-chain bridging functionality. Users can now transfer ETH, stablecoins, and other tokens directly through the **Uniswap Bridge interface**. The integration supports transfers between: - Ethereum Mainnet - Base - Optimism - Arbitrum - Additional networks **Key benefits include:** - Transfers completed in seconds - Low fees (cents per transaction) - Seamless user experience within Uniswap This follows a similar integration pattern, as PancakeSwap recently adopted Across for one-click cross-chain swaps between BNB Chain, Arbitrum, Base, and Ethereum.

**Across protocol has officially crossed the $30 billion mark** in total bridging volume, cementing its position as a major player in cross-chain infrastructure. The milestone represents significant growth from the $27.5 billion reported in July, when the protocol had facilitated **17.3 million transfers** for over 4 million users. **Key metrics from Q2 2025:** - $3.25 billion in volume - 2.43 million transfers - 635,000 active users The protocol's **intent-based architecture** continues to drive adoption by enabling fast, decentralized transfers between rollup chains and Ethereum mainnet through its unique combination of optimistic oracles and bonded relayers.
