Tron: what it is and how it works with Trezor

Tron is a blockchain network used mainly for moving tokens, especially stablecoins like USDT. Its native coin is TRX.

This article explains what Tron is, how it works, and how it handles tokens and fees.

How Tron works

Tron uses an account-based model: your account is a single address that does not change, and it holds your TRX and all your tokens together.

Tron uses delegated proof of stake. Anyone can run to be a Super Representative, and TRX holders vote by staking their TRX: the more you stake, the more votes you have. Every six hours the votes are counted, and the 27 candidates with the most votes produce the blocks until the next count, adding new transactions roughly every three seconds. Voters can earn a share of the rewards their chosen Super Representatives receive.

Network rules, including the fee charged for energy, are set by Super Representative proposals and votes. This means Tron's fees can change over time when the validators agree to adjust them.

What Tron is used for

Tron is a smart contract blockchain. Most activity on it is stablecoin transfers: as of early 2026, Tron holds more USDT than any other network, close to half of all USDT in circulation, and it is widely used for peer-to-peer payments and exchange withdrawals.

TRX is Tron's native coin. You stake (freeze) TRX to get bandwidth or energy, which also gives you Tron Power, the weight used to vote for Super Representatives. TRX is burned to pay for a transaction when you don't have enough of those resources.

Smart contracts and addresses

Tron runs smart contracts on the Tron Virtual Machine (TVM). The TVM is close to Ethereum's virtual machine and uses the same contract language, Solidity, so similar contracts can run on either network.

But Tron is still a separate network with its own address format. A Tron address is 34 characters long and starts with a capital "T", not the "0x" used by Ethereum and other EVM networks. The two are not interchangeable: you cannot send Tron assets to an Ethereum-style address, or the reverse.

Bandwidth and energy

Most networks charge a single fee for every transaction. Tron instead uses two resources: bandwidth and energy.

Bandwidth covers simple transactions, such as sending TRX. Energy covers smart contract execution, which includes sending any token such as USDT.

A token transfer uses a large amount of energy. A USDT transfer uses about 64,000 units of energy if the recipient's USDT balance is already above zero, or roughly double that (around 130,000 energy) if it is currently zero. The exact amount can vary, but the amount you send makes no difference: moving 5 USDT and 5,000 USDT cost the same.

You get bandwidth and energy by staking (freezing) TRX. If your account does not have enough of a resource, the network burns TRX from your balance to cover it instead.

Tokens on Tron

Tokens on Tron follow shared standards. The main one is TRC-20, Tron's version of Ethereum's ERC-20, used for smart contract tokens like USDT. Tron also has TRC-721 and TRC-1155 for non-fungible tokens (NFTs).

An older standard, TRC-10, issues tokens directly through the Tron protocol without running on the TVM. TRC-10 tokens cannot use smart contract features.

Staking and voting

Staking, called freezing on Tron, locks your TRX to give you network resources. Alongside bandwidth or energy, staking gives you Tron Power, the voting weight used to choose Super Representatives. The more TRX you stake, the more Tron Power you have. Voters can earn a share of the rewards their chosen Super Representatives receive.
