Improved speed and cost savings with Metis on Ethereum L2

Building Web3 dApps on Metis is easier with Blast! Blast's RPC endpoints enable developers to prototype, deploy, and scale projects with fast response times and low prices.

Benefits of Metis

About Metis

Metis is an L2 scaling solution that uses optimistic rollup technology to enable the Ethereum blockchain builders to handle increased transaction volumes more securely, and efficiently.
Metis also supports an EVM-compatible virtual machine called the Metis Virtual Machine (MVM).

In addition to its Layer-2 scaling technology, Metis offers additional solutions such as:
- An NFT bridge and storage solution that enables users to transfer NFTs between the Ethereum blockchain and the Metis Andromeda network. If a user mints an NFT on Ethereum and sends it to Metis, the network protocol offers NFT storage.
- A framework for DACs (Decentralized Autonomous Companies), designed to offer support for governance problems, internal management, or incentives.
- A middleware platform called Polis that records transaction history.

All of these solutions function on top of Metis' Andromeda (its own blockchain framework), which the chain uses to enable access to the Ethereum network.
Metis offers a decentralized framework, ensuring that power and control are distributed across its network, enhancing trust and security. The platform's approach to ecosystem governance involves its community, allowing stakeholders to have a say in its development and evolution.
Metis is also notable for its user-friendly approach, offering simple integration processes that lower the barrier to entry for developers and businesses.
