Vitalik Buterin Discusses Ethereum Development Pain Points

Across Protocol has announced support for bridging to **Ink**, Kraken's new Layer 2 network designed for DeFi applications. **Key Details:** - Ink is Kraken's scaling solution built to handle high transaction volumes for decentralized finance - Users can now bridge assets to Ink using Across Protocol's infrastructure - The integration connects Kraken's centralized exchange ecosystem with Layer 2 DeFi capabilities The bridging support arrives as Kraken expands its onchain presence, with the $INK token previously announced for integration into Kraken's product suite. The move represents Kraken's strategy to blend centralized and decentralized finance offerings. Across Protocol uses bonded relayers and optimistic oracle technology to facilitate transfers between Ethereum mainnet and Layer 2 networks.

Superbridge has launched a major update by integrating Across protocol as its underlying infrastructure. This integration brings Across's optimistic oracle technology and bonded relayer system to Superbridge users. **Key Features:** - Decentralized instant transactions between rollup chains and Ethereum mainnet - Single-sided liquidity pools for improved efficiency - Enhanced cross-chain bridging capabilities The partnership combines Superbridge's user interface with Across's proven bridging technology, potentially offering faster and more reliable cross-chain transfers for users moving assets between different blockchain networks.

**BarterDeFi has integrated the Across Swap API**, enabling users to perform cross-chain swaps directly within the app. - Users no longer need to switch between different platforms or tabs to execute cross-chain transactions - The integration leverages Across Protocol's infrastructure for seamless asset transfers - This follows a previous integration in April that enabled in-app cross-chain deposits with no bridging fees The feature aims to streamline the user experience by consolidating cross-chain functionality into a single interface.

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.
