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 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 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 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 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.*

MPC and intents.Optimex have completed integration with Across protocol, enabling seamless cross-chain trading between EVM-compatible chains and native Bitcoin. The integration aims to simplify cross-chain transactions by: - Eliminating the need for multiple wallets - Reducing complexity in blockchain interactions - Providing automated wallet management This development marks a significant step toward more user-friendly DeFi infrastructure, particularly for users looking to trade between different blockchain ecosystems.

Across Protocol continues to expand its cross-chain capabilities, now offering near-instantaneous transfers between multiple blockchain networks. The protocol leverages advanced bridging technology to facilitate quick and cost-effective transactions. Key features: - Transactions complete in seconds - Low-cost transfer fees - Secure cross-chain swaps - Multiple network support The integration represents a significant step forward in blockchain interoperability, making cross-chain transactions more accessible to users.

Vitalik Buterin, Ethereum's co-founder, shares insights on challenges faced by developers building on Ethereum. The discussion highlights various technical hurdles while contrasting them with solutions like Across Protocol's crosschain capabilities. Key points: - Focus on identifying core development friction points - Emphasis on crosschain functionality as a critical solution - Documentation available for developers looking to integrate crosschain features Developers interested in crosschain solutions can explore implementation through Across Protocol's documentation.

Ethereum's scaling solutions, while successful, have led to unexpected fragmentation across the network. Key developments: - L2 rollups solved scalability but created liquidity silos - Multiple chains now operate independently, causing user experience friction - Industry leaders including Uniswap team are working on solutions Current focus is on creating seamless cross-chain experiences to make Ethereum feel unified again. Across protocol offers one solution through optimistic oracle technology and bonded relayers. *Next steps involve improving bridge infrastructure and standardizing cross-chain communication protocols.*

Across Protocol announces integration with Arbitrum Fast Withdrawals, reducing transfer times from 7 days to just 15 minutes. This upgrade significantly enhances the Orbit ecosystem's interoperability. Key features: - Enables rapid transfers between chains - Maintains capital efficiency for relayers - Ensures security for users - Supported by major RaaS providers including Ankr, AltLayer, Caldera, Conduit, and Gelato The system relies on validator committees for transaction processing, requiring unanimous votes for state transitions. This approach particularly benefits AnyTrust chains through their DAC trust model.
