What your wallet gives away, and how to check yours

Most people think of a wallet address as a random string. It is closer to a bank statement that anyone can read and that never expires. Whoever has it can see what it holds, every payment it ever made and a surprising amount about the person behind it. This article walks through what one address gives away, with real examples, and points to a free check that shows it for your own.

Everything in it, forever

Bitcoin and Ethereum are public ledgers. That is how they work without a bank: anyone can verify every balance and every payment. The price is that an address shows what it holds today, what it held at any moment in the past and every payment in and out, with amounts and dates. Satoshi Nakamoto’s first address, from the very first Bitcoin block, still holds 57.58 BTC and has received more than 80,000 payments, most of them small amounts from strangers. Every one of them is listed for anyone to read.

One link is enough

An address does not carry a name. It does not need to. One link puts a name on all of it: a withdrawal from an exchange that knows you, a payment to a friend, an address in a social post, or a readable name such as an ENS name. In 2020 the names, phone numbers and home addresses of 272,000 hardware-wallet buyers were published from a leaked customer database, ready to be matched with on-chain balances.

What a stranger can read

• Exchanges. Payments to or from an exchange are labelled on public explorers. The exchange knows its customers by name, so a leak, a hack or a court order is all it takes to put that name on the address.
• Linked addresses. When a Bitcoin transaction spends from several addresses at once, they almost always belong to one wallet. The Bitcoin whitepaper says as much: such transactions “necessarily reveal that their inputs were owned by the same owner.”
• Reused addresses. Receiving every payment on the same address ties all of its senders to each other, and to you.
• Other chains. An Ethereum address is the same on Base, BNB Chain, Arbitrum and every other EVM chain, so what you do on each of them adds up to one profile.
• Apps. Every swap, loan and position is public and points back to the address, so anyone can follow your trades.
• Time zone. When an address sends matters too. Six quiet hours a day usually mean sleep, and that points to a time zone and a rough region.

Check your own

The wallet check on redacted.gg looks for all of this on any Bitcoin or Ethereum address and turns it into a score from 0 to 100. It runs in your browser: your browser asks public explorers directly, so redacted.gg never sees the address and nothing is stored.

What you can do

• Use a new address for every payment. Most Bitcoin wallets do this by themselves. It keeps payments from piling up on one address.
• Keep names off your main wallet. A readable name or an address in your profile links everything that wallet holds to you.
• Think before you withdraw from an exchange. The exchange knows the address you withdraw to, so everything that address does later is tied to your account there.
• Act from a private account. With Redacted you move coins into a shared Reserve once, then swap, trade, borrow and earn from a private account with no visible link to your wallet. The deposit stays public, like any transaction, and new money waits about two hours, which makes it harder to match to what you do next.

Financial privacy is not about hiding. It is about not handing a stranger your balance, your habits and your daily rhythm with every payment. Check what your wallet gives away, and decide from there.
