About

EVVM let's anyone create Virtual Blockchains on top of any chain just deploying smart contracts. Basically it's an infra-less abstract blockchain inside any blockchain! You can use any existing network like Ethereum, Polygon, CELO, Hedera and others. Just use the MATE Metaprotocol (our EVVM testnet) or spin up your own virtual blockchain environment by simply deploying our smart contracts, instead of running a whole new network (infra, consensus, distribution, etc). We offer one-command deployment tools, npm packages, a fully Scaffold-EVVM and more tooling ready to use! Using the EVVM you have the benefits of a custom blockchain, easy to modify and without managing physical infrastructure: no validators or dedicated nodes!. When an EVVM instance runs on any chain (as set of Solidity contracts) it abstracts the core components of a blockchain, inheriting the security of the underlying chain. A "blockchain within a blockchain", similar to a virtual machine in computing, like VMWare and VirtualBox. We are looking for any novel use cases, including: Gasless Payments, Custom Native Tokens, Improve x402 & ERC-8004 capabilities and more. Developers can also use EVVM as a sandbox to experiment with new features or Ethereum improvements (like testing new opcodes or economic models) in an controled environment, without affecting the main chain.

Connect your project with the MATE Metaprotocol (our official EVVM tesnet deployed on Sepolia) with a x402 agents OR make your dApp. 1. Using 'async nonces' and 'executor' is a plus. 2. Optionally integrate any of the available services and other functionalities: MATE NameService, MATE Staking, p2p Swap, etc.

Qualification Requirements

You must use the official MATE Metaprotocol deployed on Sepolia or any of its official services.

Create a new EVVM Service or a cusotmized EVVM that you believe is needed today. Check the Mate NameService, p2p Swap and Staking as references and/or starting point. We are looking forward to see more Services and customized chains related to -gasless- Retail, -async- DeFi, Governance, Institutions (Gov, Schools, Librares, etc) and Gaming.

Qualification Requirements

For this implementation you can deploy your own custom EVVM or use the MATE Metaprotocol (our testnet EVVM already deployed on Sepolia).
