Kaia (ex. Klaytn) tooling
MetaMask
On node access details, click Add to MetaMask.
caver-js
caver-js is a JavaScript library enabling developers to interact with a Klaytn node via HTTP connection. It supports all Klaytn APIs.
Install caver-js.
Connect over HTTP.
web3.js
Build DApps using web3.js and Klaytn nodes deployed with Chainstack.
Install web3.js.
Connect over HTTP.
HTTP
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 Klaytn nodes deployed with Chainstack.
Install web3.py.
Connect over HTTP. See also EVM node connection: HTTP vs WebSocket.
HTTP
Use the 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)
See also node access details.
Ethers.js Extension for Kaia
See Ethers.js Extension for Kaia.
Hardhat
Configure Hardhat to deploy contracts and interact through your Klaytn nodes.
Install Hardhat and create a project.
Create a new environment in hardhat.config.js
:
where
- YOUR_CHAINSTACK_ENDPOINT — your node HTTPS or WSS endpoint protected either with the key or password. See node access details.
- YOUR_PRIVATE_KEY — the private key of the account that you use to deploy the contract
Run npx hardhat run scripts/deploy.js --network chainstack
and Hardhat will deploy using Chainstack.
See also Forking EVM-compatible mainnet with Hardhat.
Remix IDE
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.
web3.php
Build DApps using web3.php and Klaytn nodes deployed with Chainstack.
Install web3.php.
Connect over HTTP:
where YOUR_CHAINSTACK_ENDPOINT is your node HTTPS endpoint protected either with the key or password
Foundry
Install Foundry.
Use --rpc-url
to run the operation through your Chainstack node.
Forge
Use forge
to develop, test, and deploy your smart contracts.
To deploy a contract:
where
- 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 node HTTPS endpoint protected either with the key or password
Cast
Use cast
to interact with the network and the deployed contracts.
To get the latest block number:
where YOUR_CHAINSTACK_ENDPOINT is your node HTTPS endpoint protected either with the key or password
