 Operating an EVM Gateway is straightforward. It can either be deployed locally alongside the Flow emulator or configured to connect with any active Flow networks supporting EVM. Given that the EVM Gateway depends solely on [Access Node APIs](https://developers.flow.com/networks/node-ops/access-onchain-data/access-nodes/accessing-data/access-api), it is compatible with any networks offering this API access.
