Smart Contract Deployment

For deploying a smart contract, you can not only use the tronWeb.transactionBuilder.createSmartContract interface, but also the tronWeb.contract().new( ) interface.

Smart Contract Invocation

Get smart contract instance

Before calling a smart contract, you need to obtain the smart contract instance first. You can create a contract instance in the following way:

let abi = [...];       
let instance = await tronWeb.contract(abi,'contractAddress'); 

Calling smart contract methods

Different types of contract methods need to be invoked by different tronweb apis:

  • Use call to execute pure or view smart contract methods, please refer to
  • Use send to execute non-pure or modify smart contract methods, please refer to method.send() for specific usage instructions.
