USDT (Tether) is the most widely used and highest-valued stablecoin in the cryptocurrency market. As of April 17, three distinct types of USDT exist across different blockchains: Omni (Bitcoin-based), ERC20 (Ethereum-based), and TRC20 (TRON-based). This guide explores their differences in speed, security, fees, and use cases.
USDT Chain Types: Omni vs. ERC20 vs. TRC20
1. Omni USDT (Bitcoin Network)
- Storage: Uses Bitcoin addresses (starting with "1").
- Transaction Fees: Requires Bitcoin (BTC) as miner fees (~0.0002 BTC per transfer).
- Security: Leverages Bitcoin’s robust Proof-of-Work (PoW) network, making it the most secure option.
- Ideal for: Large transfers where security is prioritized over speed.
2. ERC20 USDT (Ethereum Network)
- Storage: Uses Ethereum addresses (starting with "0x").
- Transaction Fees: Paid in ETH (Gas fees). Costs vary with network congestion.
- Balance: Represents ~3% of total USDT supply.
- Ideal for: Moderate transfers, especially in DeFi applications.
3. TRC20 USDT (TRON Network)
- Storage: Uses TRON addresses (starting with "T").
- Transaction Fees: Free transfers (sponsored by TRON’s high throughput).
- Speed: Processes 1,500 TPS, making it the fastest option.
- Security: Uses DPoS consensus (27 super nodes), perceived as less decentralized.
- Ideal for: Small, frequent transfers requiring speed and cost-efficiency.
