A new proposal, HIP-4, brings Across protocol integration for 1:1 cross-chain swaps.
Key Details:
- Enables direct cross-chain token swaps at 1:1 ratios
- Leverages Across protocol's bridging infrastructure
- Uses optimistic oracle and bonded relayers for decentralized transactions
- Facilitates instant transfers between rollup chains and Ethereum mainnet
The integration aims to simplify cross-chain operations by removing the need for multiple steps or intermediary tokens. Users can now swap assets across different chains more efficiently through the Across protocol's single-sided liquidity pools.
This builds on previous cross-chain swap developments announced in April 2025, marking continued progress in interoperability solutions.
HIP-4 is here. Integrate Across for 1:1 crosschain swaps.
Vertex Protocol Launches Transaction Support in Front-End Interface

Vertex Protocol has rolled out **transaction support** directly in its front-end interface, marking a significant upgrade to user accessibility. **Key Updates:** - Transaction functionality now integrated into the main interface - New statistics dashboard features added - Blog section launched for community updates The platform previously introduced VRTX token tracking capabilities, allowing users to monitor buy-backs and staking activity through their [stats dashboard](https://stats.vertexprotocol.com/). This front-end enhancement streamlines the user experience by eliminating the need for external tools to execute transactions, bringing core functionality directly to traders and liquidity providers.
Across Protocol Shuts Down Discord, Moves Support to AI-Powered Frontend
Across Protocol is closing its Discord server, transitioning to a read-only state before complete shutdown. **Key Changes:** - Discord becomes read-only as first step in multi-phase sunset process - User support now handled through @fin_ai integrated directly into the frontend - Move aims to reduce friction and improve user experience **Rationale:** The team frames this as a strategic shift to platforms that better serve users as both Across and the broader industry mature. They emphasize this represents evolution rather than abandonment of community engagement. The integration of AI-powered support directly into the interface eliminates the need for users to navigate to separate platforms for assistance.
Across Protocol Advocates for Seamless Cross-Chain UX Through Intent-Based Bridging
Across Protocol published an article arguing that users shouldn't need to know they're bridging between blockchains. The piece, titled 'The Invisible Bridge: Why Users Shouldn't Know They Are Crossing Chains,' makes the case that: - **Intent-based systems** can handle cross-chain operations automatically - Users should simply click "buy" or "stake" without manual bridging steps - The technical complexity of moving between chains should happen **under the hood** The article reflects a broader industry push toward **chain abstraction** - making multi-chain interactions as simple as using a single blockchain. Rather than requiring users to understand gas tokens, bridge interfaces, and destination chains, intent-based protocols can route transactions automatically. This approach could significantly lower barriers to entry for mainstream users who find current cross-chain workflows confusing or intimidating.

Across Co-founder Discusses New Proposal to Solve Blockchain Fragmentation
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 Enables Crosschain USDC Transfers via CCTP Integration
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.
