What is Energy Used for in the TRON Blockchain?

The primary purpose of energy in the TRON ecosystem is to execute smart contracts. Smart contracts are computer programs that automatically execute, control, or document certain events and actions. In the TRON network, they can be used to create decentralized applications (DApps) that operate on the blockchain and are not controlled by any single organization.

Energy is primarily consumed in the following scenarios (the provided data on consumption is a summary of blockchain information and is approximate):

ATTENTION! After October 2024, the values for energy and bandwidth have changed. The article presents data up to October 2024, which may no longer be relevant today.

TRC20 Tokens:
TRC20 standard tokens consume bandwidth and energy. For example, transferring 20 USDT tokens requires 32,000 units of energy and 339 units of bandwidth, which is equivalent to approximately 13.44 TRX in energy and 1 TRX in bandwidth.

Using Smart Contracts:
Calling smart contracts also incurs energy and bandwidth costs. For instance, buy/sell transactions on the DEX Sunswap involve interacting with smart contracts that consume account resources.

Deploying TRC20 Contracts:
Publishing a standard contract requires 580,000 units of energy, equivalent to about 150 TRX. For non-standard token contracts, energy consumption can range from tens of thousands to millions of units.

Deploying TRC721 Contracts:
Publishing a TRON NFT based on the TRC721 protocol consumes 10,610 units of bandwidth and 1.67 million units of energy, corresponding to fees of 10.61 TRX and 471 TRX, respectively.

In addition to executing smart contracts, energy in TRON is used for:

Reducing Transaction Fees:
Having energy available allows for reduced or completely waived transfer fees, which is especially beneficial for active traders.

Increasing Transaction Speed:
A sufficient supply of energy ensures rapid execution of operations and smart contracts, while a lack of energy may lead to delays or cancellations.

Maintaining Network Stability:
Freezing TRX to obtain energy also provides additional protection and stability for the entire blockchain system.
Thus, energy is a vital resource in the TRON ecosystem, underpinning the execution of smart contracts, DApps, and many other functions of this cryptocurrency network. Proper energy management can significantly optimize the user experience and reduce costs on the blockchain.

Great! Now we’ve learned how to save on transaction fees when transferring USDT TRC20 on the TRON blockchain! You can explore more interesting materials in the "How It Works?" section.
