How to sell energy

This article shows how to fill an existing energy order by selling/delegating TRON energy through the API.

Note

Do you prefer to sell automatically? Check the guide

Explanation of the code

1. Select the order and define delegation:

   const ID = 5383310;
   
   const AMOUNT = 1000;
   const RESOURCE = "ENERGY";
   const LOCK = true;
   const LOCK_PERIOD = 300;

2. Creates the delegation transaction and sign it:

   const raw_tx = await tronWeb.transactionBuilder.delegateResource(...);
   const signed_tx = await tronWeb.trx.sign(raw_tx);

3. Send the transaction to the API:

   axios.post(ENDPOINT, params)

Example of how to sell energy:

Node.js

const axios = require('axios');
const TronWeb = require('tronweb');

const TRON_NODE = "https://api.trongrid.io"; // or "https://api.nileex.io"
const PRIVATE_KEY = "YOUR_PRIVATE_KEY";

const ENDPOINT = "https://api.tronenergy.market/order/fill";

const tronWeb = new TronWeb(
    new TronWeb.providers.HttpProvider(TRON_NODE),
    new TronWeb.providers.HttpProvider(TRON_NODE),
    TRON_NODE,
    PRIVATE_KEY // this should match origin address
);

const ID = 5383310; // The order id to get filled
const ORIGIN_ADDRESS = "YOUR_ORIGIN_ADDRESS"; // OPTIONAL: add this only for multisignature wallets
const ADDRESS = "YOUR_SELL_ADDRESS";
const RECEIVER_ADDRESS = "YOUR_RECEIVER_ADDRESS";
const RESOURCE = "ENERGY";
const AMOUNT = 1000; // Energy amount, min 50000
const LOCK = true;
const LOCK_PERIOD = 300; // Time in seconds

async function sell() {

    // signed_tx
    const raw_tx  = await tronWeb.transactionBuilder.delegateResource(AMOUNT, RECEIVER_ADDRESS, RESOURCE, ADDRESS, LOCK, LOCK_PERIOD);
    const signed_tx = await tronWeb.trx.sign(raw_tx);

    const params = {
        id: ID,
        address: ADDRESS,
        origin_address: ORIGIN_ADDRESS,
        signed_tx: JSON.stringify(signed_tx)
    };

    axios.post(ENDPOINT, params)
        .then((res) => {
            console.log("all ok, order filled");
            console.log(res.data);
        })
        .catch((error) => {
            console.error("woops, something wrong happened!");
            console.error(error.response?.data);
        });
}

sell();
