i will transfer about $300k tether from my trustwallet to coinbase wallet using either erc or trc.
if some one knows my both wallet address and time of the transaction; any how can that person do something about that transaction? steal, hack, freeze the account etc?
during the transaction or after?

there is no way he have access to my private keys but i am reading some weird things and wonder if is possible. i am also aware in that case everyone have access to wallet addresses steal and it will be chaos but maybe there is something that i dont know and i want to make sure.

i dont know if it matters or not but to coinbase wallet is newly created wallet

thx for your help
