No Filecoin support

Chainstack deprecated support for Filecoin nodes. This page here is for legacy and in case you may find it useful.

​
MetaMask

You can set your MetaMask to interact through your Filecoin nodes..
1
Open your MetaMask and click the network selector.
2
In the network selector, click Custom RPC.
3
In the New RPC URL field, enter the node endpoint endpoint.
4
In the Chain ID field, enter the ID of the network:
  • Calibration Testnet: 314159
5
Click Save.

​
Truffle

Configure Truffle Suite to deploy contracts to your Filecoin nodes.
1
Install Truffle Suite, HD Wallet-enabled Web3 provider, and create a project.
2
Create a new environment in truffle-config.js, add your mnemonic phrase generated by a wallet and the Filecoin endpoint instead of FILECOINT_ENDPOINT:
const HDWalletProvider = require("@truffle/hdwallet-provider");
const mnemonic = 'pattern enroll upgrade ...';
...
module.exports = {
 networks: {
    chainstack: {
        provider: () => new HDWalletProvider(mnemonic, "FILECOIN_ENDPOINT"),
        network_id: "*"
    },
   }
  }
};

​
Remix IDE

To make Remix IDE interact with the network through a Filecoin node:
1
Get MetaMask and set it to interact through a Filecoin node. See Interacting through MetaMask.
2
In Remix IDE, navigate to the Deploy tab. Select Injected Provider - MetaMask in Deploy & run transactions.
This will engage MetaMask and make Remix IDE interact with the network through a Filecoin node.

​
web3.js

Build DApps using web3.js and Filecoin nodes.
1
Install web3.js.
2
Connect over HTTP or WebSocket.

​
HTTP

Use the HttpProvider object to connect to your node HTTPS endpoint and get the latest block number: 
const Web3 = require('web3');

const web3 = new Web3(new Web3.providers.HttpProvider('FILECOIN_ENDPOINT'));

web3.eth.getBlockNumber().then(console.log);
where FILECOIN_ENDPOINT is your node HTTPS endpoint.

​
WebSocket

Use the WebsocketProvider object to connect to your node WSS endpoint and get the latest block number: 
const Web3 = require('web3');

const web3 = new Web3(new Web3.providers.WebsocketProvider('FILECOIN_ENDPOINT'));

web3.eth.getBlockNumber().then(console.log);
where FILECOIN_ENDPOINT is your node WSS endpoint protected either with the key or password.

​
web3.py

Build DApps using web3.py and Filecoin nodes.
1
Install web3.py.
2
Connect over HTTP or WebSocket. See also EVM node connection: HTTP vs WebSocket.

​
HTTP

Use the HTTPProvider to connect to your node endpoint and get the latest block number. 
from web3 import Web3

web3 = Web3(Web3.HTTPProvider('FILECOIN_ENDPOINT'))
print(web3.eth.blockNumber)
where
  • FILECOIN_ENDPOINT — your node HTTPS endpoint
  • HOSTNAME — your node HTTPS endpoint hostname

​
WebSocket

Use the WebsocketProvider object to connect to your node WSS endpoint and get the latest block number. 
from web3 import Web3

web3 = Web3(Web3.WebsocketProvider('FILECOIN_ENDPOINT'))
print(web3.eth.blockNumber)
where
  • FILECOIN_ENDPOINT — your node WSS endpoint
  • HOSTNAME — your node WSS endpoint hostname
See also WebSocket connection to an EVM node.

​
ethers.js

Build DApps using ethers.js and Filecoin nodes.
1
Install ethers.js.
2
Connect over HTTP or WebSocket. See also EVM node connection: HTTP vs WebSocket.

​
HTTP

Use the JsonRpcProvider object to connect to your node endpoint and get the latest block number: 
const { ethers } = require("ethers");

var urlInfo = {
    url: 'FILECOIN_ENDPOINT'
};
var provider = new ethers.providers.JsonRpcProvider(urlInfo, NETWORK_ID);

provider.getBlockNumber().then(console.log);
where
  • FILECOIN_ENDPOINT — your node HTTPS endpoint
  • NETWORK_ID — Filecoin network ID:
    • Calibration Testnet: 314159

​
WebSocket

Use the WebSocketProvider object to connect to your node WSS endpoint and get the latest block number: 
const { ethers } = require("ethers");

const provider = new ethers.providers.WebSocketProvider('FILECOIN_ENDPOINT', NETWORK_ID);

provider.getBlockNumber().then(console.log);
where
  • FILECOIN_ENDPOINT — your node WSS endpoint
  • NETWORK_ID — Filecoin network ID:
    • Calibration Testnet: 314159
