USDT 转账指南与 TRC20、ERC20 交易查询
转账前核对 USDT 网络、收款地址和提币手续费，转账后用 TxID 查询确认状态与到账问题。
USDT 是什么？转账选 TRC20 还是 ERC20？
USDT 是 Tether 发行的美元稳定币，在多个区块链上流通。转账前，先打开收款方的 USDT 充值页，再在发送端选择相同网络。TRC20 对应 TRON，ERC20 在这里指 Ethereum 主网。核对两端支持的网络、收款地址及任何必填标签。首次向新地址转账，可以在满足最低充值额的前提下先做小额验证。
第一次给新地址转 USDT，要核对哪几项？
先从收款方的充值页面获取地址与网络，粘贴后核对完整地址和任何必填标签。再查看最低充值额、手续费和预计到账金额。若收款信息与上次不同，重新从收款方页面确认。
USDT 提币手续费和转账网络费要看哪里？
从交易所提币时，提交前核对平台显示的手续费和预计到账金额。用自托管钱包转账时，检查手续费估算和该网络需要的手续费代币。费用可能随网络或平台规则变化。
USDT 转账为什么提示手续费代币不足？
许多网络使用该链的手续费代币支付链上操作费用。先看钱包所选网络和确认页写明的费用币种，再核对相应余额。交易所提币则以平台确认页显示的扣费币种为准。
USDT 交易记录怎么查询？
从发送端的提币或钱包记录复制交易哈希（TxID），在该网络的区块浏览器查看状态、收款地址和确认数。链上已确认而平台尚未入账时，核对最低充值额和平台要求的确认数，再带着 TxID 联系收款方客服。
USDT 转账多久到账？选错网络怎么办？
到账时间取决于网络状态和收款方要求的确认数。若发现选错网络，先保存 TxID、发送和接收地址以及网络名称，再用收款方的官方客服渠道查询是否能找回。已确认的链上交易通常无法撤回。

USDT Transfers, TRC20 and ERC20, and Transaction Lookup
Check the USDT network, recipient address and withdrawal fees before sending. Use the TxID to check confirmations and deposit issues.
What is USDT, and how do I choose TRC20 or ERC20?
USDT is a dollar-pegged stablecoin issued by Tether on multiple blockchains. Open the recipient's USDT deposit screen first, then choose the same network on the sending side. TRC20 refers to TRON, and ERC20 here refers to Ethereum mainnet. Check that both sides support the network and confirm the address and any required tag. A small test that meets the minimum deposit can help when using a new address.
What should I check before sending USDT to a new address?
Get the address and network from the recipient's deposit page. After pasting, check the full address and any required tag. Review the minimum deposit, fee and estimated amount. Reconfirm from the recipient's page if any information has changed.
Where can I check USDT withdrawal and network fees?
Check the exchange's displayed withdrawal fee and estimated amount before submitting. In a self-custody wallet, check the estimated network fee and the token needed to pay it. Fees may change with the network or platform rules.
Why does my USDT transfer say I lack the fee token?
Many networks use their own fee token to pay for on-chain transactions. Check the selected network and fee currency shown on the wallet confirmation screen, then check the matching balance. Exchange withdrawals use the fee currency shown by the platform.
How do I look up a USDT transfer?
Copy the transaction hash (TxID) from the sending wallet or withdrawal record and check the status, address and confirmations on that network's block explorer. If the chain has confirmed the transfer and it hasn't been credited, check the recipient's minimum deposit and confirmation requirement before contacting support with the TxID.
When will a USDT transfer arrive, and what if I chose the wrong network?
Timing depends on network conditions and the recipient's confirmation requirements. If you selected the wrong network, save the TxID, the sending and receiving addresses and the network name. Ask the recipient's official support whether recovery is possible. Confirmed on-chain transfers generally cannot be reversed.
