When you transfer USDT through AstroPay, a network fee applies depending on the blockchain you choose. The fee covers the cost of processing your transaction and is standard across all crypto platforms.
Available networks
AstroPay supports four blockchain networks for USDT transfers:
Ethereum (ERC-20): widely supported, ideal for transfers to or from other platforms.
Tron (TRC-20): popular network for USDT transfers.
BNB Smart Chain (BSC): Binance's network, fast and reliable.
Polygon: typically a lower-cost option.
