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.


  • 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": [
"" # make sure the RPC node url is using https protocol
"explorer": {
"url": ""
"start": 2516442, # specify the number of the first block
"logo": "ipfs://QmXTwpE1SqoNZmyY4c3fYWy6qUgQELsyWKbgJo2Pg6K6V9"

3. Check if the network is set correctly

Head to 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
