# Custom RPCs

## Custom MetaMask Networks

When adding custom networks to your MetaMask wallet, keep in mind that malicious RPCs do exist. To learn about possible dangers, read this article by MetaMask. Never allow an untrusted source to add a network to your MetaMask automatically, and always do your due diligence before adding one manually.

The process for adding custom RPCs is slightly different for each wallet. Please refer to the wallet documentation for guidance.

## How to Add Custom Networks

MetaMask provides great documentation for adding custom networks to your MetaMask Desktop and Mobile App. If you are unsure how to do it, please check this illustrated[ article](https://metamask.zendesk.com/hc/en-us/articles/360043227612-How-to-add-a-custom-network-RPC). Please check <https://rpc.info> or <https://chainlist.org> to add all of the chains we are on by connecting your wallet and clicking the blue "add to MetaMask" button next to each chain. If this does not work correctly, feel free to paste the details in manually.

## Chainlist.org

A popular service for adding new RPCs to your wallet is [chainlist.org](https://chainlist.org). It is simply a list of providers and has a connection option to make adding RPCs very simple. As always, choose wisely, and check URLs.

## RPC List

The list below includes officially approved RPCs for each chain, along with alternative public RPCs that are generally trusted by members of the Elk community. As always in Web3, choose carefully, you are in control and your decisions are your own.
