发送前核对
Before sending, verify the address character by character and confirm the asset and network match. QR codes are convenient but can be replaced by malware, so confirm important payments through a second channel.
确认与费用
A submitted transaction may wait for confirmation while fees and congestion change. Never resend just because someone is pressuring you; check the transaction hash in a trusted explorer first.
收款验证
Recipients should rely on their own wallet or node, not a screenshot or chat message. Merchants should state the required confirmations and refund process.
出错处理
A wrong address usually cannot be reversed. Save the hash and timeline, and never pay an upfront fee to a supposed recovery service or reveal a key.
