How to use this guide
Turn the topic into a decision note.
Use this when adding Base to a wallet, app, or deployment configuration. Keep network setup separate from provider evaluation.
Use Base as the network name and 8453 as the chain ID.
Use an RPC URL from official documentation or a provider account you control.
Check the returned chain ID, open the explorer, and run one read call before saving or deploying.
Add the Base network fields
Use Base as the network name, 8453 as the chain ID, a verified Base RPC URL, and a Base explorer URL. Copy endpoints only from official documentation or a provider account you control.
Choose the RPC URL for the environment
A public endpoint can be useful for setup and light testing. An app with user traffic should use an endpoint chosen for its methods, limits, monitoring, support, and fallback plan.
Test before saving or deploying
Confirm that eth_chainId returns 0x2105, load a known Base address or transaction in the explorer, and test one read call before relying on the configuration.

What to do after this guide
After saving the configuration, confirm chain ID 8453, open a known address or transaction in the explorer, and test one read call. Move to the provider directory only when you need managed capacity, support, or a fallback endpoint.
