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?
None can do something with your transactions. The transactions can't be reverted or disrupted. The only thing that can happen when the blockchain gets down and your transaction got stuck but this is an impossible thing to happen for sure. You shall not worry about that. As long as you were sending to the right address of your coinbase address and it must be fine.
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
The possible thing is when you were randomly signing transaction for token that has already sent as dusting attack for your address. Never try to touch any suspicious token in your wallet.
