What is Tron (TRX) crypto?

Tron is a public blockchain that runs smart contracts and digital tokens, and TRX is its native cryptocurrency. If you are asking what Tron crypto is used for today, the main answer is moving stablecoins, especially Tether's USDT. The project was founded in 2017 by Justin Sun.

What is the Tron network?

Tron's mainnet went live on May 31, 2018. The network uses delegated proof of stake. TRX holders stake their coins and vote, and 27 elected block producers, called Super Representatives, create new blocks.

Smart contracts on Tron run on the Tron Virtual Machine. It is designed to be close to Ethereum's virtual machine, though the developer docs list a number of differences, such as address formats. The smallest unit of TRX is the sun. One TRX equals 1,000,000 sun.

What is TRX used for?

TRX has three main jobs, according to the Tron developer docs:

• Paying for resources. TRX can be burned to pay for a transaction.
• Staking. Locking TRX gives an account a share of network resources and voting power.
• Unit of account. TRX is the base currency across Tron's DeFi apps.

What is TRC-20 USDT?

TRC-20 is Tron's standard for tokens, similar to ERC-20 on Ethereum. USDT issued on Tron is often called TRC-20 USDT. It is the same stablecoin, but it lives on a different blockchain from ERC-20 USDT, so you must pick the matching network when you send it.

Tron carries a large share of USDT. In the second quarter of 2026, about $87.9 billion of USDT circulated on Tron, roughly 47.6% of tracked USDT supply, according to Messari's State of TRON report as cited by Crypto Briefing. That was more than the $78.7 billion on Ethereum. Tron also handled about $2.1 trillion in stablecoin transfers in that quarter. Our guide to USDT vs USDC explains how the two largest stablecoins differ.

How do Tron fees compare with Ethereum fees?

The two networks charge fees in different ways. On Ethereum, users pay gas fees in ETH. The base fee rises when blocks are fuller than a target and falls when they are emptier, so costs move with demand.

Tron instead meters two resources. Bandwidth covers the size of a transaction in bytes. Energy covers the computing work of a smart contract, such as a USDT transfer. Each account gets 600 free Bandwidth points every 24 hours, but no free Energy. Users get more by staking TRX or by having another account delegate resources to them. If they run short, TRX is burned to cover the gap.

Rhino.fi, a cross-chain payments firm, argues that predictability is Tron's main draw for stablecoin users. Resource prices are set through governance, so a busy network does not by itself push the cost of a transfer higher.

Crypto prices are volatile and a token can lose most of its value.
