Revoke USDT Approval or Move Funds?
Wallet Security is read-only and costs 1 USDT for one wallet / analysis network.
Short answer
Revoking is not always the safest first step. If you do not recognize the permission, if someone online is guiding you, or if your seed phrase/private key/device may be compromised, moving funds to a new wallet you created yourself may be safer.
When revoking can help
Revoking may help when the risk is a token allowance and you know which spender was approved. It usually means setting the allowance to zero through a trusted interface or direct contract interaction.
When moving funds may be safer
Move funds first if you suspect private-key exposure, device compromise, social engineering, or an unfamiliar account-control permission. Revoking one allowance does not fix a wallet that someone else can still control.
Important warning
USDTCheck will never give you a safe wallet address. Create the new wallet yourself and never send funds to an address supplied by someone claiming to help you.
