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

This thread does not belong to bitcoin development & technical discussion.

As long as the person do not know your seed phrase or private key, he has no access to your wallet by knowing just the time of transaction and your address.

Also avoid malware.

Also avoid address poisoning (https://bitcointalk.org/index.php?topic=5433343.msg61556293#msg61556293).

There's no cryptographic/on chain risk of this.

You can have funds intercepted in your wallet via malware though such as clipboard hijacking (where what you copy gets changed before pasting it in the wallet).

First of all I would advise you change wallet from a third party based like Coinbase as that is a third party wallet which can turn offline any day and you can forget about your coins as that saying says "Not your keys,not your coins".

Having said that,the other thing has been already explained that if you use Windows (I don't know about Mac) it is always best to double check the address where you are sending your funds even if it is one of your addresses as there is this malware that changes this to the hacker address,so far in Linux I am not aware of such vulnerability.

They only know it if they know it and there's not that risk on it unless they know you personally and might attack you with a $5 wrench which is known as the $5 wrench attack.
Other than that, what you can think of is usually when these exchanges sees that you've made such transactions, that might cause them a trigger and you might get asked for some more verifications.

Care to show some examples the weird things you have read? I think you are having a misconception about most of it.


ETH enforced OFAC-compliant block, if your fund is somehow tainted with bad stuff that violates some regulation, it could be censored. Do also note, some stablecoins have a feature to freeze funds, so it is another possibility. Overall, A general or even the most sophisticated hacker can't do much with only the address and time of the transactions.


Coinbase Wallet is a self-custodial wallet, as they have claimed. So as long OP keeps the seed phrases secure, it should be able to be exported to other wallets. Also, Coinbase Wallet is not a third-party wallet, I'm not even sure what you mean by a third-party-based wallet.

Well if they can get a hold of your phone and or laptop because they have installed backdoor on it, then maybe they can steal your coins.

But if you have total control of private keys, then it will be good. However, don't just sit and be confident that there are no hackers that can get into your account. Just practice safe security, always put a password on your wallet that is hard to guess and your seed should not be be saved in your mobile phone or laptop.

Agreed unless you are going to send there just to flip it into something else that's fine, but people NEED to stop using exchanges as wallets, at least for a good portion of their portfolio.  I just don't get it.  If sent to coinbase I'd flip it into whatever you want then pull immediately off the site.  In terms of intercepting your transaction I don't under stand.  If they have access to your private keys then yep they do but your public Addy being known won't cause any harm.

I am not really an IT or blockchain expert but i don't think, that there is any way that a hacker can do anything to access your tokens or coins while they are transfered within the blockchain because to do that this would actually mean that the hacker could access the blockchain itself and if that would ever happen to a chain then this would be the absolute worst case and that blockchain would be dead instantly because it could not be used anymore.
The only thing than can happen is that someone gets access to one of your wallets and once the tokens have arrived they just take them and send them to their own wallet, but for that you also have to make a lot of mistakes before, like saving your private key on your PC and then the PC gets hacked or infested by a virus or something.

With the wallet address anyone can see the history but not possible to get those funds into their wallets no matter what unless they infect your trust wallet and replace their address while you're making the transaction so be careful with receipient address and amount you want to send to it twice or thrice before clicking send, cause once send its irreversible forever.

Firstly if someone can actually know your sending wallet and also the time of your wallet it goes to show how irresponsible you are and this may just be an avenue for you to get scammed.

Although those information aren’t enough for you to get scammed if you have the correct receiver address then it would go through, but I am skeptical that you would be insensitive enough to give out such informations.

I don't know how a stranger can know your wallet address and transaction time? Is it only a close friend of yours?
However, even if he knew, he wouldn't be able to do anything unless he had access to your wallet or private key.
Also if you want to transfer this large amount of money I recommend you to use a hard wallet instead of coinbase.

There’s no way to hack this transaction if you are sure about the security of your wallet and I suggest to deposit little by little so you can know if your account is compromise or not. Also, use the highest security option in coinsbase and do your KYC because that is a huge money and to avoid being questioned.

Anyway, why transfer to coinbase? Are you going to trade or just hold there? Because exchange wallet is not safe at all.

Clipboard hack is the only one I can think of that can compromise transfers from one address to another. Well, if someone has your private keys that works too, but I haven't really heard of a man in the middle (MITM) attack on cryptocurrencies and I guess that's what you're trying to say here. Or it could be a reverse transaction exploit, but that can easily done by anyone nowadays and isn't really much of a hack. Anyway, the algorithms involved in transfers of funds from one address to another is cryptographically secure, so you should not worry about your coins being hijacked along the way.

If its already on the blockchain, I don’t think it can still be hacked but my worry here is that coinbase might see this as suspicious especially your account is still new and with that big money, it can hit the red flag which can put you on a bigger risk. If there’s no need to transfer that one time, better to divide it and don’t go all in to coinbase, trust wallet is already a good and secured wallet so make sure to protect it as well.

You do not explain us why you want to transfer your coins to coinbase, if you want to buy some bitcoin and ethereum that is all right, but at some point you need to transfer those coins to a wallet you control and with 300k in assets then you need a hardware wallet, it seems you are afraid of the many different ways in which you could be hacked and I would guess you lack the experience to protect your computer as you should, so get a hardware wallet and forget about most of those issues, as you are a big enough target for hackers out there.

There are certain ways where a transaction can be hacked or hijacked.  There are malware that can change the pasted address  so that is one of the proof that wallet tranfer can be hack or hijack.  The best way to avoid this is to always double check the address that we pasted.  Other than that, I do not think that there is another way of hacking or hijacking a transfer.


It can be hack if someone got your private key. But I think @OP is asking another thing about being hack while transferring a casino from one address to another.

Only the wallet addresses? everyone can do that randomly, get two wallet addresses in any blockchain, but they can't do anything about it.


Hackers can get or steal your crypto if they know your private key, mnemonic phrase in a wallet that you have control of, known as non-custodial. Coinbase wallet on the other hand is custodial, meaning all control is with Coinbase.

So if by chance, they known your password on that account, then obviously they can steal it right away from you.

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.



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.

For the first one or about the malwares, make sure we already installed a strong anti-virus and then they must always be updated so that they can scan our devices for available malwares and other threats. Yet we must not be confident but we should always make it a practice to re-check the receivers address if it's a correct one or not.

To be able to do this in an efficient way, I check a few characters on the beginning and on the last part of a crypto wallet address. On the second one or about the private keys, make sure we avoid sites or transactions which requires us to paste our private keys because they are obviously a scam. We should also store our private keys offline. Transacting big amount is also fine as long as you know to your self that you are clean and free from illegal transactions in the past.

Which someone you refer? since both Trust wallet and Coinbase wallet are closed sources, there's a chance the developer know your seed phrase and able to backdoor your wallet, but it's just my assumptions.

As long as you're not sharing your seed phrase or any other personal information, your wallet will be safe. But if you hold centralized coin, the developer can able to freeze your coins because they have a control over all of their coins.

Sometimes people use various methods to pull cryptocurrencies from wallets. I think main one is regular malwares. They don't need to know your private key(s). They just inject code into your computer through Malware so they can change receiver address to their own. This is why people should check their addresses at least 2-3 times. But if you are sure your transactions are safe noone can interrupt it other than malicious Blockchain projects which are rare anyways.

If anyone out there is still using Windows and they do not want to switch to Linux they need to make sure to download Windows from the official sources and obtain a legitimate license from Microsoft, avoid installing any pirated software and avoid clicking on any suspicious links as this can easily lead you to expose your computer to all kind of dangers, and when it comes to checking the address to which you want to send your coins I think it is not longer enough to check the first and last characters, and instead you should check the whole thing just to be sure you are not sending your coins to the wrong address.

There's always a chance of you getting hacked if the windows you are using came from another person or in short p2p. It is common to see people injecting malwares back then on these pirated application and they have a more powerful reason to do and repeat it over and over because they can now gain something now from it. My friend is a victim of this kind of malware attack and he's not careful enough not to check the address he is sending to, He regretted it instantly and format and changed his operating system without a second thought. Hackers are clever but I don't think OP main problem about intercepting an on going transaction can be hacked, There is a much more higher chance of being hacked before and after the transaction.

If you are uncertain whether your transaction will reach your Coinbase wallet, it is advisable to test the transfer with a small amount of funds first. Sending $1 to test whether the transfer can be completed smoothly is a better option.
In terms of wallet security, it depends on how clever you are in securing your seed phrase. Wallets can be hacked due to users' negligence in securing their wallet passwords or seeds. For an amount as large as $300k, it is recommended to use a hardware wallet for better security.

Even before bitcoin was created there was already a large problem with Windows been full of viruses, trojans and keyloggers, but since then this problem has increased dramatically as now hackers know they not only can steal your coins but that most likely they are never going to get caught as long as they are careful about it, so in my opinion anyone that is holding a large amount of money in cryptocurrencies needs to use Linux, at least when it comes to the OS in which their wallet is installed.

From my perspective, it's not possible for wallet to wallet transfers to be hacked. For anyone to gain access to your wallet, they need your seed phrase or mnemonic keys. The only way something of such could happen is if your device has been compromised by malware, that has the tendency of changing the address copied to a different one without your notice.

thank you all answering and i have better understanding as i don't want to make any expensive mistake.

i have a final question; i did some research and came up with fake btc transactions;

so if i receive 1BTC to my Trust wallet, and verify that transaction through blockchain explorer, and have at least 3 confirmation;
is that btc balance and or transaction on the blockchain can be faked?
is it possible to send some other shit-coin to my btc wallet and appear as a BTC but it is not transferable or usable
thank you

this is what i am talking about
https://www.youtube.com/watch?v=8-ygzLXShkg

i was scared to download the sw as many sw are might be infected with the virus, also i don't believe the youtube comments also;
but is this possible?

any comment on this greatly appreciated

As long as you do not share your private keys or seed phrases with anyone, it is highly unlikely that someone can steal, hack, or freeze your cryptocurrency assets during or after the transaction.
If someone knows your wallet addresses and the time of the transaction, they can see the transaction on the blockchain, but they cannot do anything to alter or stop it.
