Vitalik Buterin Discusses Ethereum Development Pain Points

Hyperliquid has implemented HIP-4, integrating Across protocol for 1:1 crosschain swaps. **Key Features:** - Direct crosschain swaps at 1:1 ratio - Integration with Across protocol's bridging infrastructure - Enables seamless asset transfers between chains This integration leverages Across's optimistic oracle system and bonded relayers to facilitate instant crosschain transactions, expanding Hyperliquid's interoperability capabilities.

**HIP-4 outcome markets are now live on Outcomexyz**, enabling users to bridge into USDH and begin trading within seconds. - The platform is **powered by Across protocol** for fast cross-chain transactions - Users can quickly convert assets to USDH and participate in outcome markets - This follows the earlier announcement of USDT0-backed prediction markets on HIP-3 The integration streamlines the onboarding process, removing friction between bridging and trading activities.

Across co-founder Hart Lambur appeared on Talking Tokens to discuss a new proposal addressing blockchain fragmentation. **Key Points:** - Lambur outlined how Across is working to solve interoperability challenges across different blockchains - The discussion covered technical approaches to bridging fragmented blockchain ecosystems - Full episode available for those interested in cross-chain infrastructure developments This follows previous appearances where Lambur discussed Across's fast interoperability solutions and Solana bridging capabilities.

Across Protocol has launched support for crosschain USDC transfers, enabling bridgers and developers to move USDC between chains. **Key Features:** - Native USDC bridging using Circle's Cross-Chain Transfer Protocol (CCTP) - Seamless integration for builders developing crosschain applications - Part of Across's expanded "bridge everything" functionality **Technical Details:** The solution leverages CCTP v2 to facilitate secure USDC transfers across supported chains. This builds on Across's recent upgrade that introduced any-token-to-any-token bridging in single transactions. For implementation details and technical documentation, visit: [Across USDC Bridge Guide](https://across.to/blog/usdc-bridge-cctp-v2) **For Developers:** The integration provides builders with tools to incorporate native USDC transfers into their crosschain applications without managing multiple bridge protocols.

Blend Money has integrated Across Protocol to enable crosschain deposits for its onchain savings product. **Key Details:** - Users can now deposit funds across different blockchain networks - [Across Protocol](https://across.to) provides the crosschain infrastructure - The integration simplifies access to Blend's savings features from multiple chains This follows Uniswap's recent crosschain implementation, also powered by Across Protocol. The move reduces friction for users who want to access savings products without manually bridging assets between networks first.
