TRON Guide

What Is TRX? TRON's Native Cryptocurrency Explained

March 14, 2026 TRXorTRC20.org

TRX — also called Tronix — is the native digital currency of the TRON blockchain. Founded by Justin Sun in 2017 and launched on its own mainnet in 2018, TRON set out to build a high-throughput, low-cost blockchain for decentralized applications and content distribution. TRX sits at the center of everything.

How TRX Powers the TRON Network

TRON's resource model splits network capacity into two types:

  • Bandwidth — consumed by every transaction (including simple TRX transfers).
  • Energy — consumed specifically by smart-contract execution (e.g., USDT-TRC20 transfers).

When you hold TRX, you can stake it to receive daily allocations of Bandwidth and Energy. Staked TRX earns these resources for free, so heavy users who stake enough TRX pay essentially zero fees. If your resource allocation runs out, the network automatically burns a tiny amount of TRX instead.

TRX for Staking and Governance

TRON uses Delegated Proof-of-Stake (DPoS). TRX holders vote for "Super Representatives" (validators) who produce blocks and earn block rewards. Staking TRX grants voting power and resource credits. This makes TRX a governance token as well as a utility coin.

TRX as Gas for TRC20 Transfers

If you hold USDT on TRON but have zero TRX, your transfers will fail — the network has no way to pay the Energy fee. This is why every guide recommends keeping a minimum balance of 30–50 TRX in any TRON wallet that holds TRC20 tokens. At 2026 prices, this costs roughly $3–$5 and protects all your USDT transfers.

Where to Get TRX

TRX is listed on virtually every major centralized exchange. You can also obtain it through decentralized exchanges on TRON, such as JustSwap, by swapping USDT-TRC20 for TRX directly. After purchasing, withdraw TRX to your personal TRON wallet (TronLink, Trust Wallet, or a hardware wallet like Ledger) to maintain self-custody.

TRX Supply and Economics

TRON has a large circulating supply (approximately 87 billion TRX), and its inflation is partially offset by transaction fee burning. The low unit price makes TRX practical for micropayment use cases and small gas-fee payments without the risk of rounding errors that plague higher-priced assets.
