TRON (TRX) is the native cryptocurrency of the TRON blockchain, a network founded by the entrepreneur Justin Sun. TRX is staked to obtain the network resources that pay for transactions, is used to vote for the operators who produce blocks, and is held as an investment. TRON's main real-world use is moving stablecoins: it carries more Tether (USDT) than any other blockchain.
TRX is the coin; the TRON network is the system it runs. Most people who use TRON are not interested in TRX itself but in sending digital dollars cheaply, especially in emerging markets, and they need only a small amount of TRX, or resources rented from others, to do so. The network is supported by the TRON DAO, the successor to the TRON Foundation.
TRON in plain terms
Imagine a busy motorway built mainly for delivery vans carrying cash. The vans are stablecoins such as USDT, and TRON is the road. Instead of paying a toll for each trip, regular users can lock up some TRX, like buying an annual pass, and in return get a daily allowance of trips. Occasional users simply pay a small toll in TRX that is then destroyed.
The road is run by a small, elected group of operators who take turns checking and recording the traffic. TRX holders choose them by voting with their locked coins, and share in the rewards the operators earn. Because the group is small, the road is fast and cheap to use, but critics say it is controlled by too few hands.
History
Justin Sun set up the TRON Foundation in 2017 and sold TRX in an initial coin offering that year. TRX first circulated as a token on Ethereum before the TRON mainnet launched in 2018, when the tokens were swapped onto the new chain. The same year TRON acquired the file-sharing company BitTorrent. Tether began issuing USDT on TRON in 2019, and low fees made it the leading network for USDT transfers; by mid-2025 more than $80 billion of USDT had been issued on TRON. In 2022 the Caribbean state of Dominica gave TRX and several TRON-based tokens legal status as authorised digital currencies.
In March 2023 the US Securities and Exchange Commission sued Sun, the TRON Foundation and related companies, alleging the unregistered sale of TRX and BitTorrent tokens and wash trading to inflate volumes. The case was paused in 2025, and in March 2026 the claims against Sun and the foundations were dismissed with prejudice, while Rainberry, the developer of BitTorrent, agreed to pay a $10 million civil penalty. Sun did not admit wrongdoing.
How it works
TRON uses delegated proof of stake. TRX holders vote for candidates, and the 27 with the most votes become Super Representatives, who take turns producing blocks every three seconds and earn TRX rewards they can share with their voters. The network runs smart contracts on a virtual machine compatible with the Ethereum Virtual Machine, and tokens on it follow the TRC-20 standard, so USDT on TRON is a TRC-20 token.
Instead of a simple fee, TRON charges in two resources. Bandwidth covers the size of a transaction, and energy covers smart-contract work such as a USDT transfer. Users obtain them by staking TRX, by renting them from others, or by paying TRX that is burned. Because burns can exceed new issuance when the network is busy, TRX's total supply has at times shrunk. TRX has no fixed maximum supply, so the balance between issuance and burning depends on how heavily the network is used.
Uses
- Stablecoin transfers. TRON is widely used for stablecoin payments, exchange deposits and crypto-based remittances, particularly in Africa, Latin America, Turkey and parts of Asia.
- Exchange transfers. Many cryptocurrency exchanges offer TRON as a default network for USDT deposits and withdrawals because a transfer usually costs far less than on Ethereum, which keeps balances moving between trading venues and over-the-counter desks.
- Resources and fees. TRX is staked or burned to pay for bandwidth and energy.
- Governance. Staked TRX gives voting power to elect Super Representatives and decide network parameters.
- Applications. TRON hosts lending, trading and stablecoin projects, many linked to Sun, including the USDD stablecoin.
Criticism and risks
TRON is often criticised as centralised, with block production limited to 27 operators and strong influence held by Sun and companies linked to him. Its popularity for USDT has also made it a favourite of criminals: researchers and authorities have linked TRON addresses to scams, money laundering and sanctions evasion, which raises the bar for sanctions screening at exchanges and payment firms. In response, TRON, Tether and the analytics firm TRM Labs set up the T3 Financial Crime Unit in 2024 to help freeze illicit funds. Holders also face the usual risks of price swings and dependence on a single stablecoin issuer for most of the network's activity.
