- Any network from the [Superchain Registry](https://github.com/ethereum-optimism/superchain-registry/) (Optimism, Base, Zora, etc).

## Anvil

- Local devnets

Anvil [implements the Otterscan API](https://getfoundry.sh/anvil/reference/#otterscan-methods), so you can point your Otterscan installation to an Anvil RPC endpoint and have an explorer for your local devnet.
