All versions of USDT are worth one dollar. What changes between TRC20, ERC20, BEP20 and Solana (SPL) is the network: its address format, its fees and how fast it confirms.
Side-by-side
| Network | Address starts with | Fee paid in | Typical fee | Typical speed |
|---|---|---|---|---|
| TRC20 (Tron) | T | TRX | Around 1–3 USD | Under 1 min |
| ERC20 (Ethereum) | 0x | ETH | Varies, often the highest | 1–5 min |
| BEP20 (BNB Chain) | 0x | BNB | A few cents | Under 1 min |
| SPL (Solana) | No fixed prefix | SOL | Fractions of a cent | Seconds |
Fees move with network demand and token prices; treat these as orders of magnitude, not quotes.
When to use each
- TRC20: the most widely supported by exchanges and P2P traders for USDT transfers.
- ERC20: when you need Ethereum DeFi apps or the receiver only supports Ethereum.
- BEP20: low fees and compatible with Ethereum-style wallets.
- Solana: very low fees and fast confirmations, if your wallet or exchange supports it.
The golden rule
Use the network the receiver supports. The cheapest network is useless if the other side cannot credit it.
Switch networks
Swap between them with the form above: ERC20 → TRC20, TRC20 → ERC20, BEP20 → TRC20, TRC20 → Solana.
