Understanding USDT Types: Omni, ERC20, and TRC20
USDT (Tether) exists in three primary forms, each operating on different blockchain networks:
Omni-USDT
- Protocol: Bitcoin's Omni Layer
- Address format: Starts with "1" (BTC-compatible)
- Transactions require BTC for miner fees (~0.0002 BTC minimum balance needed)
- Best for: High-value transfers requiring maximum security
ERC20-USDT
- Protocol: Ethereum's ERC-20 standard
- Address format: Starts with "0x"
- Gas fees paid in ETH
- Ideal for: Moderate-speed transactions with balanced cost/security
TRC20-USDT
- Protocol: TRON's TRC-20 standard
- Address format: Starts with "T"
- Zero transaction fees (network-level)
- Recommended for: Small, frequent transfers
