Mantle

Mantle is a high-performance Ethereum Layer 2 designed to bridge traditional finance and crypto through low fees, fast finality, and a modular architecture with zero-knowledge proofs. The ecosystem features institutional-grade products like mETH Protocol, Mantle Index Four, functionBTC, and the UR smart money app, with a $3B+ treasury and growing TVL. Community members highlight the project's longterm vision, skilled team (many from Bybit), cost-efficient scalability, and real-world use cases, though some note visibility has declined relative to the technical innovation.
