Mantle
Mantle is a technology stack for scaling Ethereum, and we strive to be EVM-compatible while doing so. Being EVM-compatible means all the contracts and tools that work on Ethereum also work with Mantle with minimal modifications. Mantle users can experiment with exciting Web3 apps, and developers can deploy smart contracts in an efficient, low-fee environment.
At its core, Mantle has been built with a modular architecture that uses an optimistic rollup with an innovative data availability solution. This allows Mantle to inherit security from Ethereum AND offer cheaper and more accessible data availability.
