Is there a way to discover a wallet information from an address?
I'm supposing to know how a person can leak our wallet information.

What information you do seek of? If what kind or type of wallet a person been using? You can eventually differentiate if he's using a custodial or non-custodial wallet if you do base up on inputs and outputs and address inside of it but if you do particularly mean of finding that persons information then thats the impossible thing and this is what makes this crypto-space decentralized and anonymous.
You can make out transactions without letting other parties know your true identity unless if youve been using exchange accounts wallets which would require KYC then your identity is known and
thats the disadvantage.

The best way is probably by using blockchain analysis websites like WalletExplorer (https://www.walletexplorer.com), which is free and can connect addresses to a single wallet by analysins their inputs and outputs (e.g you receive X in Address A, Y in Address B, and sends X + Y to address C; this assumes A and Y are connected to the same person, since they were spend together). They do not work all the time though, and can have a few false-positives. But that doesn't necessarily connect any of them with a real life identification.

A normal person can't easily find out this information about you.

The Walletexplorer.com (https://www.walletexplorer.com) can help you out. But there is prerequisite to use it. The address you use to discover a corresponding wallet has had at least one transaction. If there is no transaction has been made on that address, the site can not help you.

If you know some addreses and think they are belong to one wallet, you can enter those addresses to the site and search. If they are belong to same wallet, you will see results from the site with same wallet ID.

As far as I know wallet explorer only works if you connect your address. For example, you have two different inputs on two addresses. You have sent them into one address. This way, both addresses have been connected and wallet explorer can give that information. On the other hand, if you do mot connect the addresses, wallet explorer will not recognise them. Tell me if I am correct or wrong.

No. You can copy & paste an address that already have transaction history into the site, Enter and get wallet id. From the result page, you will have that address' wallet ID and wallet IDs of addresses which received money from the wallet. So if you want to connect two addresses, you you check wallet IDs to see overlaps between them.

Maybe I don't know about the feature you mention or maybe it does not exist.

there is no direct link between a single address and the rest of the addresses that may be in the same wallet unless the user of that wallet connects the addresses together and even then you still can never be sure if the addresses are connected (ie. belong to the same wallet). for example two different wallets/person can combine (consolidate) their coins (transaction outputs) into the same transaction, which may make it look like the addresses involved belong to one entity whereas it doesn't. although that is only theoretical and in practice nobody does that.

Question is quite confusing to me. I think only I am the one who assuming that OP just not asking about wallet id which would be fine via wallet explorer as mentioned by above users. For more clarity, only details would be leak whatever public on the blockchain. Your wallet credential wouldn't be identify or leak from your bitcoin address like seed, encryption password or private keys. Those data already in public on the blockchain would leak or whatever like public key, transaction hash or wallet id. So don't mix wallet id with wallet credential.

no chain analysis service has ever been reliable. they do a half decent job on too obvious connections and mess the rest up. just look at some of the statistics they release from time to time when they try to advertise their services, they never make any sense or are based on any reliable analysis. for example what they refer to as "CoinJoinMess" contains lots of inputs that never had anything to do with CoinJoin at all.

Depends on which wallet, normally, your info isn't attached to wallet address and that the purpose of blockchain and decentralization. But the reason you need to know a wallet info is still unclear, only wallet that needs email registration carries details which can only be accessed by the wallet provider/ developer. All they need is the address, and they check for the name. They can't leak such details out.
