Boba Network RPC Endpoint

Flat-rate Boba Network RPC provider and Boba Network RPC node access: free tier, no KYC, HTTP & WebSocket. Boba Network mainnet chain ID 288.

Boba Network is an EVM-compatible Ethereum Layer 2 optimistic rollup known for Hybrid Compute, a feature that lets smart contracts call external compute and APIs during execution. The Ethereum deployment uses ETH for gas, with BOBA serving as the network's governance and utility token.

About Boba Network

Boba Network launched its public Ethereum Layer 2 mainnet in 2021, originally associated with the OMG Foundation, and distributed its BOBA governance token to OMG holders who bridged to the network. It is an EVM-compatible optimistic rollup focused on reducing gas costs and improving throughput.

Boba's distinguishing feature is Hybrid Compute, which lets smart contracts trigger off-chain computation and external API calls (including AI and Web2 data) within a transaction, enabling logic that would be impractical to run fully on-chain. Boba also operates deployments on other base chains such as BNB Smart Chain; the chain 288 deployment is the Ethereum L2, where ETH is the gas token.

Common Use Cases on Boba Network

• Hybrid Compute (off-chain compute and API calls)
• AI-integrated smart contracts
• DeFi protocols
• On-chain gaming
• NFT projects
• Low-cost EVM transactions

Boba Network Ecosystem

Boba supports DeFi, gaming, and infrastructure projects, with Hybrid Compute integrations enabling contracts to reach external data and AI services; OolongSwap is among the native DeFi deployments.
