Polygon zkEVM tooling
Current API limitations
Polygon zkEVM currently supports most of the wide-known JSON-RPC methods.
-
See zkEVM methods to try out the exclusive
zkevm_*
namespace methods. -
See Polygon zkEVM documentation for the full list of supported methods.
Interaction tools
MetaMask
On node access details, click Add to MetaMask.
Development tools
Truffle
Configure Truffle Suite to deploy contracts to your Polygon zkEVM nodes.
Install Truffle Suite, HD Wallet-enabled Web3 provider, and create a project.
Install the dotenv package to securely load your sensitive variables from a .env
file
Create a new environment, and define a new network, in truffle-config.js
:
Hardhat
Configure Hardhat to deploy contracts and interact through your Polygon zkEVM nodes.
Install Hardhat and create a project.
Install the dotenv package to securely load your sensitive variables from a .env
file
Create a new environment in hardhat.config.js
:
web3.js
Build DApps using web3.js and Polygon zkEVM nodes deployed with Chainstack.
Install web3.js.
Connect over HTTP or WebSocket.
HTTPS
Use the HttpProvider
object to connect to your node HTTPS endpoint and get the latest block number:
where YOUR_CHAINSTACK_ENDPOINT is your node HTTPS endpoint protected either with the key or password.
web3.py
Build DApps using web3.py and Polygon zkEVM nodes deployed with Chainstack.
Install web3.py.
Connect over HTTP or WebSocket. See also EVM node connection: HTTP vs WebSocket.
HTTPS
Use HTTPProvider
to connect to your node endpoint and get the latest block number.
where
- YOUR_CHAINSTACK_ENDPOINT — your node HTTPS endpoint protected either with the key or password
- HOSTNAME — your node HTTPS endpoint hostname
- USERNAME — your node access username (for password-protected endpoints)
- PASSWORD — your node access password (for password-protected endpoints)
node.js
You can build a web app to query data using node.js and axios:
- YOUR_CHAINSTACK_ENDPOINT — your Chainstack node endpoint protected either with the key or password. See node access details.
query
— your JSON-RPC query. In this case, to get the latest block number.
ethers.js
Build DApps using ethers.js and Polygon zkEVM nodes deployed with Chainstack.
Install ethers.js.
Connect over HTTPS or WebSocket. See also EVM node connection: HTTP vs WebSocket.
HTTPS
Use the JsonRpcProvider
object to connect to your node endpoint and get the balance of any address:
where
-
YOUR_CHAINSTACK_ENDPOINT — your node HTTPS endpoint protected either with the key or password
-
NETWORK_ID — Polygon zkEVM network ID:
- Mainnet:
1101
- Testnet:
1442
- Mainnet:
Brownie
Install Brownie.
Use the brownie networks add
command with the node endpoint:
where
-
ID — any name that you will use as the network tag to run a deployment. For example,
chainstack-testnet
. -
NETWORK_NAME — any name that you want to identify the network by in the list of networks. For example,
zkEVM
. -
YOUR_CHAINSTACK_ENDPOINT — your node HTTPS or WSS endpoint protected either with the key or password
-
NETWORK_ID — Polygon zkEVM network ID:
- Mainnet:
1101
- Testnet:
1442
- Mainnet:
Example to run the deployment script:
Remix IDE
To make Remix IDE interact with the network through a zkEVM node deployed with Chainstack:
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.
