command with the node endpoint.
where YOUR_CHAINSTACK_ENDPOINT — your node HTTPS or WSS endpoint protected either with the key or password. See node access details.
Invoke any methods from Web3 JavaScript API.
Example below demonstrates how to get the balance of an address in wei value and convert it to ether value:
You can use GraphQL on a dedicated node on the paid plans.
You can query data using the graphical interface.
On Chainstack, navigate to your dedicated Scroll node. See node access details.
Hover over GraphQL IDE URL and click Open.
In the graphical interface that opens, run a GraphQL query.
Example to get the latest block number:
You can build a web app to query data using node.js and axios:
where
query
— your GraphQL query. In this case, to get the latest block number.See also Using GraphQL with EVM-compatible nodes.
On node access details, click Add to MetaMask.
Configure Hardhat to deploy contracts and interact through your Scroll nodes.
Install Hardhat and create a project.
Create a new environment in hardhat.config.js
:
where
Run npx hardhat run scripts/deploy.js --network chainstack
and Hardhat will deploy using Chainstack.

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