You send someone your public wallet address so they can check whether a payment arrived. They can look up the transfer. They can also see other public activity at that address. What they cannot do with the address alone is spend the tokens. That distinction matters just as much when you choose what to share with a financial app or an AI agent.
Crypto wallet tracking features and privacy
On Ethereum, a blockchain explorer lets you look up a public address and inspect its wallet activity without connecting a wallet. A transfer record can tell you which address sent the funds, which address received them and when the transaction was confirmed. It won’t tell you whether you paid a supplier or simply moved tokens to a second wallet you own.
What Bluwhale adds to a public wallet address
With Bluwhale for Individuals, you bring wallets, exchanges, cards and bank accounts into one financial profile. That wider view matters when you own both ends of a transfer. The explorer shows tokens leaving an address. Knowing the destination is also yours explains why the assets still belong in your portfolio, with any network fee accounted for separately.
Bluwhale gives you a WhaleScore for your connected financial picture. Use it when you want to review financial health across accounts. When your question is narrower, such as “Which wallet received my USDC?”, start with the network and transaction hash. If you bring the question to a Bluwhale agent, choose which connected data it can access. Reviewing yesterday’s transfer requires no permission to spend today’s balance.
What is your wallet asking you to do?
Look up an address
For crypto wallet tracking on a public network, the address is enough to start. Paste it into the appropriate explorer and check the network before reading the balance. Keep your recovery phrase and private key out of any tracker or conversation. Ethereum’s account guide explains what the key controls.
Connect a wallet
A site can ask your wallet to share the account you select. Read the connection prompt and check the requesting domain. Sharing an address lets the site associate it with your session. A later request to sign or approve something deserves a fresh look.
Sign a message or transaction
Read what the signature authorizes. A message can prove that you control an address, but some signed messages grant permissions that another party can use later. A prompt showing no gas fee is no guarantee that signing is harmless.
Approve token spending
An ERC-20 allowance gives a specific spender permission to use a token up to a limit. Check the network, token, spender and amount. If all you came to do was check an incoming payment, you can close the request and look up the transaction directly.
What changes when you give an address a name?
Imagine an address sends USDC to a second address every Friday. An observer can see the pattern. If you tell a service that the second address is your savings wallet, you have supplied a new piece of information. Consider who can see that label, especially before you share a watchlist, export or screenshot.
In Bluwhale, you choose which agents and partners can access your connected data. A question about one transfer may only need its network, amount and destination. A question about the share of your finances held in crypto needs a broader set of accounts. Give the agent the context that fits the question. See how Bluwhale handles permissions and financial actions.
Two tokens can use the same ticker
Before you label a token payment, verify the network and full token contract. For USDC, compare the contract with Circle’s official list by network. The token symbol alone cannot identify the asset. If an export gives you raw units, look up the token’s decimal precision before converting the amount. The ERC-20 specification makes that metadata optional.
Which record should you keep?
Keep the network and transaction hash so you can reopen the original record. For an ERC-20 transfer, also record the token contract. Native ETH has no token contract to look up. You can inspect this public Ethereum transaction without connecting a wallet or signing anything.
What to do when you stop using an app
Open your wallet’s connected-sites list and disconnect the app you no longer use. Then review any token allowances you granted on the relevant network. MetaMask explains the two controls: disconnecting the site leaves existing token approvals in place. Removing a connection also leaves the public transaction history intact.
For questions about information shared with Bluwhale, consult the Bluwhale Privacy Policy. When you’re ready to review holdings across several accounts, start with Bluwhale’s crypto portfolio tracker. For deposits, borrowing or staking inside a protocol, go to the DeFi portfolio tracker.
Can someone see my bank balance if they know my wallet address?
The public blockchain shows on-chain records associated with the address. A bank balance in your Bluwhale profile comes from a separate account connection. Sharing a public address does not, by itself, grant access to that connected account.
Does a signature always move funds immediately?
No. A signature can authenticate you or grant a permission that is used later. Read the requested operation before signing, even if your wallet shows no immediate transfer.
