Tether exists on many blockchains, but two networks dominate: Ethereum (ERC20) and Tron (TRC20). The tokens hold identical value, yet the experience of moving them differs dramatically.
Fees and speed
TRC20 transfers typically cost well under one dollar and confirm in seconds. ERC20 transfers can cost several dollars during network congestion because they must pay Ethereum gas.
Compatibility
ERC20 is accepted by virtually every DeFi protocol and exchange. TRC20 is widely supported by exchanges but rarely usable in DeFi. Always confirm the receiving platform supports the exact network before sending.
Our recommendation
For everyday transfers and payments, TRC20 is hard to beat. For DeFi and maximum compatibility, use ERC20. OneChainCrypto supports both networks so you can pick what suits your needs.
