​

web3.py

1. Install web3.py.
2. Connect over HTTP.

​

HTTP

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

• Mainnet: 9745
• Testnet: 9746

​

ethers.js

1. Install ethers.js.
2. Connect over HTTP.

​

HTTP

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

const provider = new ethers.JsonRpcProvider("YOUR_CHAINSTACK_ENDPOINT", {
  chainId: 9745,
  name: "plasma"
});

provider.getBlockNumber().then(console.log);

​

Hardhat

1. Install Hardhat and create a project.
2. Create a new environment in hardhat.config.js:
   Javascript

   require("@nomicfoundation/hardhat-ethers");
   ...
   module.exports = {
     solidity: "0.8.26",
     networks: {
       plasmaMainnet: {
         url: "YOUR_CHAINSTACK_ENDPOINT",
         chainId: 9745,
         accounts: ["YOUR_PRIVATE_KEY"]
       },
       plasmaTestnet: {
         url: "YOUR_CHAINSTACK_ENDPOINT_FOR_TESTNET",
         chainId: 9746,
         accounts: ["YOUR_PRIVATE_KEY"]
       }
     }
   };
   
   where
   • YOUR_CHAINSTACK_ENDPOINT — your node HTTPS or WSS endpoint protected either with the key or password. See node access details.
   • YOUR_CHAINSTACK_ENDPOINT_FOR_TESTNET — your Plasma testnet node endpoint.
   • YOUR_PRIVATE_KEY — the private key of the account that you use to deploy the contract
3. Run npx hardhat run scripts/deploy.js --network plasmaMainnet to deploy to mainnet or --network plasmaTestnet for the testnet.

​

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.

​

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 --chain-id 9745

• 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 will use to deploy the contract
• YOUR_CHAINSTACK_ENDPOINT — your mainnet node HTTPS endpoint protected either with the key or password
• YOUR_CHAINSTACK_ENDPOINT_FOR_TESTNET — your testnet node HTTPS endpoint

​

Cast

cast block-number --rpc-url YOUR_CHAINSTACK_ENDPOINT --chain-id 9745
