# BNB Chain > Build for the Next Billion Web3 Users BNB Chain is a community-led blockchain ecosystem powered by BNB, composed of BNB Smart Chain (L1), opBNB (L2), and BNB Greenfield (storage). BNB Chain is an open, permissionless blockchain ecosystem for building Web3 apps. It includes BNB Smart Chain (EVM L1), opBNB (L2), and BNB Greenfield for decentralized storage, all powered by the BNB token. - Type: Network - Sector: Blockchain Platforms - Status: Active - Founded: 2018-10-01 - Profile: https://thegrid.id/profiles/BNB_Chain ## Products - [BNB Smart Chain](https://thegrid.id/profiles/BNB_Chain): BNB Smart Chain is a decentralized, EVM-compatible Layer 1 blockchain for building smart contracts, dApps, and DeFi. It offers fast transaction processing and low fees for a wide range of blockchain applications. (L1, Live, Main Product) - [opBNB](https://thegrid.id/profiles/BNB_Chain): opBNB is a Layer 2 scaling network for BNB Smart Chain. It processes transactions off-chain using optimistic rollups to reach higher throughput and lower fees while relying on BNB Smart Chain for security. (L2, Live) - [BNB Greenfield](https://thegrid.id/profiles/BNB_Chain): BNB Greenfield is a decentralized storage infrastructure providing blockchain-based data management with EVM programmability, enabling users to store files and digital assets while maintaining data ownership and control. (Decentralized File Storage, Live) - [BNB Chain Bridge](https://thegrid.id/profiles/BNB_Chain): BNB Chain Bridge is a cross-chain bridge aggregator for transferring assets between various blockchain networks and BNB Smart Chain. (Bridge, Live) - [BNBAgent SDK](https://thegrid.id/profiles/BNB_Chain): BNBAgent SDK is a developer framework for deploying and operating AI agents onchain on BNB Chain. It provides agent identity registration with trackable reputation, a standardized job lifecycle with native escrow for task creation, funding, delivery, and settlement, and decentralized dispute resolution. A toolkit simplifies agent registration, task management, and payment workflows. (AI Agent Framework, Open Beta) - [opBNB Bridge](https://thegrid.id/profiles/BNB_Chain): opBNB Bridge is the native bridge for moving BNB and BEP-20 tokens between BNB Smart Chain and the opBNB Layer 2. Deposits are locked in a standard bridge contract on BNB Smart Chain and credited on opBNB, while withdrawals are proven against opBNB state posted to BNB Smart Chain before funds are released. It serves as the canonical route for moving assets onto opBNB, with deposits and withdrawals made from a dedicated web interface. (Bridge, Live) - [BNB Greenfield Bridge](https://thegrid.id/profiles/BNB_Chain): BNB Greenfield Bridge is the native bridge for transferring BNB between BNB Smart Chain and the BNB Greenfield storage network. It relays transfers through the cross-chain messaging layer that connects the two networks, in either direction. Users move funds from a web interface by connecting a wallet holding BNB on the source network. (Bridge, Live) ## Assets - [BNB (BNB)](https://thegrid.id/profiles/BNB_Chain): BNB is the native token of BNB Chain, an EVM-compatible Layer 1 blockchain ecosystem. It is used for paying transaction fees, staking for network security, and governance participation on BNB Smart Chain. Originally issued as an exchange token by Binance, BNB evolved into the gas and staking asset across a multi-chain ecosystem spanning a Layer 1, a Layer 2, and a decentralized storage network.
