Across Protocol has announced its Crosschain Summer initiative, running through August 2025. The program aims to enhance cross-chain interoperability and user experience.
Key features:
- Optimistic oracle integration for secure transfers
- Enhanced bridging between rollup chains and Ethereum mainnet
- Improved transaction speeds and cost efficiency
- Focus on decentralized instant transactions
The initiative builds on developments from June's crosschain infrastructure updates, marking a significant step in blockchain interoperability.
Users can participate by bridging assets through the Across Protocol interface.

Across August. Crosschain Summer.
ZK season is heating up. @SuccinctLabs, Union, Boundless, and Cysic are pioneering the next era of blockchain. But ZK isn鈥檛 just powering proofs, it鈥檚 transforming "cross-chain" too. With SP1 now live in V4, @AcrossProtocol is making bridging faster, cheaper, and more
Across Protocol Enables Cross-Chain Bitcoin Swaps on Multiple Networks

Across Protocol has launched cross-chain Bitcoin swaps on Optimex, expanding their bridging capabilities across multiple EVM-compatible networks. The integration now supports: - Arbitrum - Optimism - Base - BNB Chain This development follows their recent MPC and intents integration, enabling native BTC swaps between EVM chains. The service builds on their existing cross-chain infrastructure, which already supports Ethereum-based transactions. Learn more: [Across Protocol Blog](https://across.to/blog/optimex)
Across Protocol Advances Cross-Chain Solutions
Across Protocol has unveiled significant updates to their cross-chain bridging infrastructure: - New optimistic oracle implementation enhances transaction verification speed - Bonded relayer network expands to support additional L2 networks - Single-sided liquidity pools now offer improved capital efficiency The protocol maintains its focus on secure, decentralized transactions from rollup chains to Ethereum mainnet. Recent improvements have reduced settlement times by 40% while maintaining the same security guarantees. *Technical integration guides and documentation are now available at [docs.across.to](https://docs.across.to)*
Optimex Launches Native BTC-EVM Chain Swaps Using Intents
Optimex has introduced native Bitcoin to EVM chain swaps using intent-based architecture. The integration leverages Across protocol's infrastructure to enable seamless cross-chain transactions. Key features: - Direct swaps between Bitcoin and EVM-compatible chains - Powered by intent-based architecture - Utilizes Across protocol's bridging technology - Combines MPC (Multi-Party Computation) with intent mechanisms This development marks a significant step toward more efficient cross-chain interoperability between Bitcoin and EVM ecosystems.
Across Protocol Implements Intent Batching with UMA
Across Protocol has integrated with UMA Protocol for optimistic verification of batched intents. The system implements: - Frequent Batch Auctions running every 10 minutes - Special focal auctions daily at 12:00 UTC - Multi-leg, conditional order synchronization - Cross-chain order book management The integration aims to provide more efficient settlement and improved liquidity across chains. The matching engine coordinates these batched transactions while maintaining decentralization. Learn more at [Ithaca Protocol](http://ithacaprotocol.io)
Across Protocol Bridging Update
Across Protocol has enhanced its bridging capabilities with key improvements: - Introduced optimistic oracle system for faster transaction validation - Implemented bonded relayers to increase security and decentralization - Launched single-sided liquidity pools for improved capital efficiency The protocol now enables near-instant transfers from Layer 2 networks to Ethereum mainnet, while maintaining decentralization principles. Transaction costs have been reduced by approximately 40% compared to previous versions. *Note: These updates are currently live on mainnet and have undergone security audits.*
