This is a sample code snippet that transfer ERC20 tokens:
import { QtumRPC } from "qtumjs"
const repoData = require("./solar.json")
const qtum = new Qtum("http://qtum:test@localhost:3889", repoData)
const myToken = qtum.contract(
"zeppelin-solidity/contracts/token/CappedToken.sol",
)
async function transfer(fromAddr, toAddr, amount) {
const tx = await myToken.send("transfer", [toAddr, amount], {
senderAddress: fromAddr,
})
console.log("transfer tx:", tx.txid)
console.log(tx)
await tx.confirm(3)
console.log("transfer confirmed")
}The full source code.
This example uses async/await (supported natively by Node 8+).
