About TRON
TRON (TRX) is a high-capacity delegated-proof-of-stake blockchain best known as the home of TRC-20 USDT — the single largest stablecoin balance on any network. Blocks arrive every three seconds, transfers cost fractions of a cent, and the network processes more stablecoin volume than any other chain, much of it in emerging markets.
TRX itself pays for bandwidth and energy on the network: holding or staking TRX gives you free daily bandwidth, and energy can be rented, which is why TRON wallets often show 'free' USDT transfers. TRX is also burned as fees, which has made its supply slightly deflationary in recent years.
On SyntheticSwap, TRX pairs with USDT (TRC-20) — the most natural pair on the network — and you can move between TRX and other assets through the form. TRX deposits are credited after 10 confirmations, about 30 seconds.
Before you swap TRX: what to check
- •Receiving address format: T… (34 characters) — a TRON address.
- •Network: TRON. TRX exists on one network here; make sure your wallet sends on it.
- •Deposit confirmations: 10 on TRON (block time 3 seconds). The rate is locked when the deposit confirms, not when you broadcast.
- •Limits: minimum and maximum are shown in the form for each pair and change with fees and liquidity.
- •Tracking: the status page shows each stage; deposits and payouts can be checked on tronscan.org.
TRX and TRC-20 USDT
TRX and USDT on TRON share the same address format (T… addresses). If you receive USDT (TRC-20) from a swap you can send it onward with rented energy or a little TRX for fees; if you receive TRX you can use it directly. Swapping TRX to USDT (TRC-20) is a convenient way to turn fee tokens into dollars without leaving the network.
Bandwidth, energy and why USDT transfers on TRON look free
TRON does not charge gas in the Ethereum sense. Every account receives a small daily allowance of bandwidth (bytes of transaction data), and staking TRX earns more bandwidth or energy — the resource that smart-contract calls such as a TRC-20 USDT transfer consume. If you hold no staked TRX, the network burns TRX from your balance to cover the missing resources; a plain TRX transfer costs a fraction of a TRX, a USDT transfer several TRX unless energy is rented or staked. This is why wallets show USDT transfers as free for some users and a few dollars for others.
For swaps the practical points are simple: a TRX deposit needs no separate fee token; a USDT (TRC-20) deposit needs a little TRX or energy in the sending wallet; and a payout to your TRON address arrives ready to use — you need TRX only when you send it onward.
Address format and common mistakes
TRON addresses are 34 characters beginning with T. TRX and every TRC-20 token share the same address, so one wallet holds both — but the network is not EVM-compatible: a 0x address is invalid here, and USDT sent from an Ethereum or BNB Chain wallet will not reach a TRON address. The form validates the format; it cannot validate that the wallet behind the address is one you control, so verify it on the device screen if you use a hardware wallet.
Exchange deposit addresses on TRON usually work for TRX and TRC-20 USDT, but some exchanges credit deposits only above a minimum. Receiving to your own wallet first is the safer habit.
