Unichain Joins Optimism's Superchain

Hyperlane, an open interoperability framework, has launched a new bridging solution on the Superchain. The protocol currently connects 40+ chains and has processed over $2B in cross-chain transactions. Key features: - Smart contract integration for cross-chain data transfer - Token bridging capabilities - Cross-chain function execution Implementation process: 1. Deploy Hyperlane on chosen chain 2. Create Warp Route for token bridging 3. Launch Warp UI for user interaction Learn more: [Hyperlane Documentation](https://www.hyperlane.xyz/) | [Web3 Infrastructure Map](https://www.diadata.org/web3-infrastructure-map/hyperlane/)

USDT0, a 1:1 backed version of Tether's USDT, has been deployed across the Superchain ecosystem. This implementation represents a significant step toward seamless cross-chain asset movement. Key features: - Direct USDT backing on Ethereum - Native multi-chain compatibility - Coming soon: 1-block finality and zero slippage - Enhanced DeFi foundation across Superchain The Superchain currently handles over 50% of L2 transactions. This deployment aligns with the vision of Ethereum scaling through interconnected cross-chain networks functioning as one cohesive system.

Optimism Collective announces its H2 strategic goal: achieving $100M monthly in cross-chain asset transfers across interoperable Stage 1 chains. The Citizens House introduces three stakeholder groups: - Top 15 chains by revenue - Top 100 apps by gas fees - End-users with verified activity Key registration requirements: - End-users must prove human status via WorldCoin - Limited spots available - Sybil protection through HumanPassport screening This follows Optimism's recent $2M bug bounty extension for Superchain protocol upgrades, which has already paid out $2.6M since 2022.
