Add a network

This page explains which networks are supported by Snapshot and how to add a new one.

EVM-based networks
Snapshot supports EVM-based networks. You can explore them at https://snapshot.org by selecting the Networks filter:
You can also follow this link directly: https://snapshot.org/#/?type=networks.
Add a new network
If you can't see the network you are looking for on the list or you want to add your custom network, follow the steps below to include it within Snapshot.
Requirements
New network must be EVM-based
RPC node must be an archive node
RPC node's url must use https 
Multicall contract must be verified and published 
Logo has to be stored on IPFS
1. Fork the repository
Create a fork of the snapshot.js repository.
2. Prepare the network details
Update the network.json file with a new JSON object storing information about the new network, following the example below:
  "30": {
    "key": "30",
    "name": "RSK Mainnet",
    "chainId": 30,
    "network": "rsk mainnet",
    "multicall": "0x4eeebb5580769ba6d26bfd07be636300076d1831",
    "rpc": [
      "https://public-node.rsk.co" # make sure the RPC node url is using https protocol
    ],
    "explorer": {
      "url": "https://explorer.rsk.co"
    },
    "start": 2516442, # specify the number of the first block
    "logo": "ipfs://QmXTwpE1SqoNZmyY4c3fYWy6qUgQELsyWKbgJo2Pg6K6V9" 
  }
3. Check if the network is set correctly
Head to https://snapshot-networks.on.fleek.co/ to test if your network is reachable:
a. Click the first network from the left sidebar and click Edit networks.json on the right side:
b. Add the JSON object with your network details (be careful with typos!) and click Apply. Do not refresh the page!
c. Search for your network in the left sidebar. You can look for the chainId or the network's name
d. Scroll up to the top of the page and check if:
it is a Full Archive node
the last block is fetched correctly (click on it to see its timestamp)
there are no errors
4. Create a Pull Request
If everything works correctly create a new PR on the original snapshot.js repo.
5. Wait for the team to approve the PR
It's now in the hands of the Snapshot team to review your changes and apply them to https://snapshot.org. 
The average time to merge a PR is 2-3 days, so please be patient! 😉
