List of L2 projects on Optimism (2026)

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.

Unichain is an Ethereum Layer 2 network built for decentralized trading and liquidity. It is an optimistic rollup with permissionless fault proofs that produces one-second blocks, with faster preconfirmations to cut latency and reduce value lost to MEV. As part of the Superchain, it connects natively with other networks in that group, and transactions pay gas in ETH.

Celo is a Layer 2 blockchain with fast finality and low fees. Transactions settle to Ethereum, and fee abstraction allows gas payment in supported ERC-20 tokens. The network supports stablecoin payments, DeFi, and AI agent infrastructure for high-frequency real-world transactions.

Automata Mainnet is an OP Stack rollup Layer 2 on Ethereum that serves as the settlement and execution layer for Automata's attestation infrastructure. Built with a two-second block time and deployed via AltLayer, it hosts DCAP attestation smart contracts enabling onchain verification of Intel SGX and TDX hardware reports. The chain uses ATA as its native currency and provides an EVM-compatible execution environment with Chain ID 65536.

Gate Layer is a Layer 2 network built on a rollup architecture that inherits security from Ethereum. It uses an optimistic rollup design and settles to GateChain, achieving high transaction throughput and fast block times while using a native asset as its gas token. The network hosts decentralized applications including token launch, swap, and bridging services, and connects to other networks through cross-chain messaging.

Ink is an Ethereum Layer 2 blockchain built on the OP Stack and part of the Superchain, designed to serve as the house of DeFi. The network features sub-second block times, low gas fees, sequencer-level security, and interoperability across the Superchain ecosystem.

HSK Chain is an Ethereum Layer 2 network from HashKey Group built for institutional on-chain finance, tokenized assets and cross-border settlement, with HSK as its native gas token. It builds on Ethereum's security with performance optimizations. Its ecosystem covers staking, launchpads, a perpetuals DEX, stock and bond tokenization and digital asset yield.

Presto is a rollup deployment platform that lets developers launch their own Layer 2 or Layer 3 zkEVM rollups and validiums. It provides multiple configuration options for chain customization and generates a live network within minutes through an automated deployment flow. Zero-knowledge proofs secure transaction validity, and the platform integrates with multiple blockchain settlement layers, including preset blueprints for use cases such as exchanges and digital banks.

Zircuit L2 is an EVM-compatible zero-knowledge rollup on Ethereum for running smart contracts at lower cost. AI monitoring at the sequencer level analyzes transactions in real time to stop malicious ones before they are processed.

Soneium Mainnet is an Ethereum Layer 2 blockchain implementing optimistic rollup technology through the OP Stack, processing transactions off-chain before batch settlement on Ethereum for reduced costs and increased throughput. The network provides EVM-compatible infrastructure for developers building applications across entertainment, gaming, and finance sectors, while maintaining Ethereum's security guarantees through its settlement layer integration.

Metal L2 implements Ethereum scaling through Optimism rollup technology, enabling BSA-compliant DeFi operations with traditional banking integrations. The system connects banks and payment partners while maintaining Layer 0 interoperability through Metal Blockchain, and includes native Metal Dollar stablecoin infrastructure, bridge functionality for Ethereum deposits/withdrawals, and blockchain explorer tools

GIWA Chain is an Ethereum Layer 2 blockchain built on the OP Stack, executing transactions through Optimistic Rollup architecture with 1-second block times. The system supports EVM-compatible smart contracts, enabling developers to deploy applications using existing Solidity tools and frameworks. It currently operates as a public testnet (GIWA Sepolia) while mainnet remains in development.

Silent Data Rollup provides privacy-enabled Ethereum Layer-2 infrastructure through trusted execution environments, enabling programmable privacy directly within smart contracts using standard Solidity code. The system processes transactions while protecting sensitive data through Intel SGX enclaves.
