This directory provides developers with a comprehensive collection of RPC endpoints across all OP Stack networks, making it easier to build, deploy, and scale applications on the OP Stack ecosystem. ## Public RPC endpoints The following table lists public RPC endpoints for all OP Stack networks. These endpoints are **rate-limited and not suitable for production use**, but are perfect for development, testing, and proof-of-concept work. For production use, please see the [Production RPC Providers](#production-rpc-providers) section below. | Chain | Public RPC URL | Documentation | | ---------- |

by OP Labs with the following policies: * Providers must submit a docs PR to the [docs](https://github.com/ethereum-optimism/optimism/tree/develop/docs/public-docs/) to be added * To be listed, providers must support at least one network in the [OP Stack ecosystem](/op-stack/protocol/superchain-registry) * Anyone can submit a PR to remove a provider that does not support a listed network ## Next steps * Want to run your own node? See the [Node operators guide](/node-operators/reference/architecture/rollup-node). * Looking for other developer tools? See [developer tools overview](/app-developers/tools) to explore more options!
