ETH and tokens are not interchangeable
Confirm whether the instruction refers to native ETH or a token and identify its network. Sending a supported asset on an unsupported chain can make recovery impossible.
Gas changes total cost
Estimate network cost before authorising and include any exchange withdrawal fee or spread. A small transfer can become poor value when multiple charges are combined.
Read contract prompts carefully
A normal transfer should not require blind approval of unrelated permissions. Reject unexpected wallet requests and never share a seed phrase with a site, agent or support contact.
