Quick Buy Energy TRONSAVE

This is a typical example of integrating fast energy purchase and sending trtions in only 1 setting.

See how to install and config SDK here

//  before 
const instance = await window.tronWeb.contract(ABI, contractAddress);
const result = await instance
        .method("...")
        .send({
                feeLimit: 1e9,
                callValue: 1000000
        });
        
        
// after use SDK
const options = {
  network: "mainnet",
}
const tronSave = new TronSave(window.tronWeb, options);
    // Replace window.tronWeb with tronSave
    const instance = await tronSave.contract(ABI, contractAddress);
    const result = await instance
        .method("...")
        .send({
                feeLimit: 1e9,
                callValue: 1000000,
                // Add options useEnergy to buy more energy if you don't have enough 
                useEnergy: true
        });

* Tronsave will do all the steps for you:

+ Estimate the energy needed.

+ If you don't have enough energy, TRONSAVE SDK will buy more energy on the TRONSAVE market.

+ Send the transaction.

You only need to sign 2 transactions:

• Buy energy transaction

• Original transaction

Extra options for send():

Options	Type	Required	Default	Description
useEnergy	boolean	false	false	set True if you want to buy energy quickly
maxPrice	number	false		The highest price you allow the sdk to buy energy
gapBuy	number	false	0.05% of the estimated energy but cannot exceed 500.	Amount of energy to buy = energy estimated - account energy + gap.
sponsor	string	false		The sponsor of the order buys energy, if available.
