/jsonrpc, /wallet, /walletsolidty support

Chainstack supports all three method endpoints:
  • /jsonrpc
  • /wallet
  • /walletsoldity
Note that the TRON nodes provided are full only (non-archive), which makes some of the methods unsupported.
For the full API reference, see the official TRON API Reference.

MetaMask

On node access details, click Add to MetaMask.

​
web3.py

Build DApps using web3.py and TRON nodes deployed with Chainstack.
1
Install web3.py.
2
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. 
from web3 import Web3

web3 = Web3(Web3.HTTPProvider('YOUR_CHAINSTACK_ENDPOINT'))
print(web3.eth.block_number)
where
  • YOUR_CHAINSTACK_ENDPOINT — your node HTTPS endpoint protected either with the key or password
See also node access details.

​
TronWeb.js

See TronWeb.

​
Hardhat

Configure Hardhat to deploy contracts and interact through your Klaytn nodes.
1
Install Hardhat and create a project.
2
Create a new environment in hardhat.config.js:
require("@nomiclabs/hardhat-waffle");
...
module.exports = {
  solidity: "0.7.3",
  networks: {
    chainstack: {
        url: "YOUR_CHAINSTACK_ENDPOINT",
        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_PRIVATE_KEY — the private key of the account that you use to deploy the contract
3
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:
1
Get MetaMask and set it to interact through a Chainstack node. See Interacting through MetaMask.
2
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.

​
Foundry

1
Install Foundry.
2
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: 
forge create CONTRACT_NAME --contracts CONTRACT_PATH --private-key YOUR_PRIVATE_KEY --rpc-url YOUR_CHAINSTACK_ENDPOINT
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: 
cast block-number --rpc-url YOUR_CHAINSTACK_ENDPOINT
where YOUR_CHAINSTACK_ENDPOINT is your node HTTPS endpoint protected either with the key or password
