# MegaYours

> Bring tokens to life

MegaYours helps developers build cross-chain digital assets by providing a blockchain stack connecting EVM chains and Solana through onchain metadata infrastructure.

MegaYours helps developers and blockchain projects create cross-chain digital assets by providing a modular stack built on Chromia's relational blockchain. Through MegaChain, Gamma Chain, Megadata, and Yours Protocol, projects can deploy assets with dynamic on-chain metadata, bridge between EVM chains and Solana without token lockups, and build composable token standards with persistent cross-chain state.

## Products

- [MegaChain](https://thegrid.id/profiles/megayours): MegaChain is an L1 blockchain that coordinates the MegaYours ecosystem through Chromia's relational architecture, enabling horizontal scalability via app chains and processing usage fees denominated in MEGA. The chain serves as the central settlement and state-coordination layer for cross-chain asset operations, facilitating metadata verification across connected networks. (L1, In Development, Main Product)
- [Gamma Chain](https://thegrid.id/profiles/megayours): Gamma Chain is a cross-chain infrastructure protocol that enables asset interoperability across EVM-compatible networks and Solana through a stakeless bridging model, eliminating the need for token deposits or lockups from connected chains. The protocol anchors to Chromia state verification to relay asset state and metadata across blockchains. (Cross-chain Infrastructure, In Development)
- [Megadata](https://thegrid.id/profiles/megayours): Megadata is a developer tooling framework that enables dynamic on-chain metadata attachment for digital assets deployed on EVM-compatible networks and Solana through Chromia-based storage infrastructure. The system exposes SDK interfaces for reading and writing asset metadata from existing token contracts, providing an alternative to off-chain storage for asset data. (Developer Tooling, In Development)
- [Yours Protocol](https://thegrid.id/profiles/megayours): Yours Protocol is a token standard built on Chromia that supports on-chain metadata storage and cross-chain asset portability for digital assets. The protocol enables assets to carry structured, mutable metadata verified on-chain rather than through external URIs, and supports both fungible and non-fungible asset types with persistent state across connected chains. (Developer Tooling, In Development)
- [YOURS.fun](https://thegrid.id/profiles/megayours): YOURS.fun is a Telegram Mini App that enables users to create, collect, and share on-chain sticker packs organized around community groups through Yours Protocol's on-chain metadata infrastructure. The platform includes AI-generated sticker creation, user profiles, and community content feeds, with sticker data stored on-chain via MegaChain. (Service Provider, Early access)

## Assets

- [Mega (MEGA)](https://thegrid.id/profiles/megayours): MEGA is the utility token of MegaChain. It is used for paying usage fees on MegaChain and Gamma Chain, and is deployed on multiple blockchains. The token provides a unified fee denomination for cross-chain asset operations, consolidating transaction costs across EVM-connected chains and Solana into a single currency. (Utility)
