• Network name: Robinhood Chain Mainnet
• RPC URL: your Chainstack HTTPS endpoint
• Chain ID: 4663
• Currency symbol: ETH
• Block explorer URL: https://robinscan.io/

• Network name: Robinhood Chain Testnet

​

ethers.js

1. Install ethers.js.
2. Connect over HTTP or WebSocket to get the latest block number.

const { ethers } = require("ethers");

const provider = new ethers.JsonRpcProvider("YOUR_CHAINSTACK_ENDPOINT");
provider.getBlockNumber().then(console.log);

const { ethers } = require("ethers");

const provider = new ethers.WebSocketProvider("YOUR_CHAINSTACK_WSS_ENDPOINT");
provider.getBlockNumber().then(console.log);

• YOUR_CHAINSTACK_ENDPOINT — your node HTTPS endpoint. See node access details.
• YOUR_CHAINSTACK_WSS_ENDPOINT — your node WSS endpoint

​

viem

1. Install viem.
2. Create a public client over HTTP and get the latest block number.

import { createPublicClient, http } from "viem";

const client = createPublicClient({
  transport: http("YOUR_CHAINSTACK_ENDPOINT"),
});

const blockNumber = await client.getBlockNumber();
console.log(blockNumber);

​

web3.py

1. Install web3.py.
2. Connect over HTTP to get the latest block number.

from web3 import Web3

web3 = Web3(Web3.HTTPProvider("YOUR_CHAINSTACK_ENDPOINT"))
print(web3.eth.block_number)

from web3 import Web3

web3 = Web3(Web3.HTTPProvider("https://%s:%s@%s" % ("USERNAME", "PASSWORD", "HOSTNAME")))
print(web3.eth.block_number)

• YOUR_CHAINSTACK_ENDPOINT — your node HTTPS endpoint protected either with the key or password
• USERNAME — the username to your node if you use a password-protected endpoint
• PASSWORD — the password to your node if you use a password-protected endpoint
• HOSTNAME — the host name of your node

​

Hardhat

1. Install Hardhat and create a project.
2. Add the network to hardhat.config.js:
   Javascript

   require("@nomicfoundation/hardhat-toolbox");
   
   module.exports = {
     solidity: "0.8.24",
     networks: {
       robinhood: {
         url: "YOUR_CHAINSTACK_ENDPOINT",
         chainId: 4663,
         accounts: ["YOUR_PRIVATE_KEY"],
       },
     },
   };
   
   where
   • YOUR_CHAINSTACK_ENDPOINT — your node HTTPS endpoint. See node access details.
   • YOUR_PRIVATE_KEY — the private key of the account you use to deploy the contract
3. Run npx hardhat run scripts/deploy.js --network robinhood and Hardhat will deploy through Chainstack.

​

Foundry

1. Install Foundry.
2. Use --rpc-url to run the operation through your Chainstack node.

​

Forge

forge create CONTRACT_NAME --contracts CONTRACT_PATH --private-key YOUR_PRIVATE_KEY --rpc-url YOUR_CHAINSTACK_ENDPOINT

• CONTRACT_NAME — name of the contract in the Solidity source code
• CONTRACT_PATH — path to your smart contract
• YOUR_PRIVATE_KEY — the private key to your funded account that you use to deploy the contract
• YOUR_CHAINSTACK_ENDPOINT — your node HTTPS endpoint protected either with the key or password

​

Cast

cast block-number --rpc-url YOUR_CHAINSTACK_ENDPOINT

Remix IDE

1. Get MetaMask and set it to interact through a Chainstack node. See MetaMask.
2. In Remix IDE, navigate to the Deploy & run transactions tab. Select Injected Provider - MetaMask in Environment.
