Metis serves as a decentralized economic platform designed to facilitate the initiation, management, and expansion of any decentralized application, enterprise, or community on the blockchain with remarkable ease and scalability. Our solution can seamlessly integrate with your current platform without requiring modifications to your existing codebase. Depending on the specifics of the smart contract stack involved, the integration process onto the Metis Layer 2 network can often be completed in less than a day due to our EVM equivalence. Furthermore, Metis redistributes 30% of the transaction revenue collected each month back to the decentralized applications deployed on our Andromeda Layer 2 network. Unlike zk Rollups, which are limited in their general EVM computation capabilities, Optimistic Rollups provide a broader scope of functionality. Additionally, zk Rollups tend to create a restrictive "walled garden" environment, posing challenges for many developers attempting to deploy their decentralized applications effectively. This creates a need for more inclusive frameworks that promote wider access to decentralized technology.

Boba represents an advanced Ethereum Layer 2 Optimistic Rollup solution designed to lower gas costs, enhance transaction speed, and broaden the functionality of smart contracts. With the assistance of community-driven liquidity pools, Boba enables rapid exits by significantly reducing the Optimistic Rollup exit timeframe from seven days to just a matter of minutes, while simultaneously offering liquidity providers enticing yield farming options. Developers within the Ethereum ecosystem will benefit from Boba’s extensible smart contracts, allowing them to create decentralized applications that utilize code executed on large-scale infrastructure like AWS Lambda, thereby facilitating the use of algorithms that would be too costly or unfeasible to run on-chain. Our approach to building Boba prioritizes both users and developers, aiming to create a practical Layer 2 solution that paves the way for the next billion users to access Ethereum. We invite you to participate in this journey and contribute to the growth of our vibrant community. Together, we can reshape the Ethereum landscape for years to come.
