Tacit in Action

Money, without the oversharing.

Your wallet history can tell strangers a lot about you. Tacit gives Bitcoin and Ethereum users a way to move value with confidential notes. Let's walk through WELD, see how a private payment works, and get clear on what privacy actually covers.

01 / Open WELD

Start at tacit dot finance slash weld, then choose Get started. WELD brings private Ether and Bitcoin payment tools together in one place. I'm using an unfunded demo identity here. You'll see the real forms, but I won't broadcast a deposit or payment.

02 / Choose your identity

You can open a Tacit identity with an Ethereum wallet, a Bitcoin wallet, or a passkey. With Ethereum, you sign a message. That's different from sending a transaction, so opening the identity doesn't spend gas. That signature matters: it controls the Tacit identity. Check that you're on the official app, and keep your wallet or passkey recovery method safe.

03 / Make ETH private

For this walkthrough, open Private Ether and choose Tacit pool. The neighboring On this device option uses a different pool, so don't mix up their instructions. Choose Make private, enter an amount, and review the funding source, quote, and fees. This route wraps Ether into confidential tETH notes. Confirm the deposit in your wallet, then wait for confirmation and settlement before using the private balance.

What a proof actually proves

So, what's a note? Think of it as a private claim to funds. Spending consumes valid notes and creates new ones. A zero knowledge proof checks the rules without exposing the hidden values. Tacit's general pool uses SP1 proofs to reconcile Bitcoin and Ethereum state. The animation is a simplified model of verification. It isn't a transaction, and it doesn't mean every Tacit pool uses the same proof system.

04 / Send privately

Back in the Tacit pool, choose Send. Enter the recipient's Tacit address or a supported name. If a name resolves, check the recipient it points to before you continue. Then review the amount and relay fees. In this route, the recipient claims the payment in their Tacit wallet. The claim fee comes out of that payment, so factor it into what they'll receive.

05 / Practice on Bitcoin signet

Want to explore the Bitcoin side first? Open Secret Sats and select signet. Use Get signet sats, then buy and shield test cBTC. After that, explore Pay privately, Receive, and Exit. These specialized pool spends are proved in your browser. Keep the test network label in view. Signet sats are test coins, and signet cBTC is a test token with no Bitcoin backing.

Private inside. Visible at the edges.

Here's the key limit: privacy has a boundary. Inside the confidential pool, amounts, consumed notes, and stealth recipients can stay hidden. Deposits and withdrawals remain public chain events. Bitcoin addresses and the public transaction graph don't disappear either. So private payments don't make your entire wallet history anonymous. Read the security details for the pool and route you're actually using.

Before you press Send

Before you send, check four things: the app, the pool, the recipient, and the fees. Wait for your deposit to settle. If a balance lookup fails, retry it. An unavailable balance doesn't mean zero. Keep a recovery method you can use, and practice on signet if you're still learning the flow.

Open. Shield. Understand.

That's the tour: open WELD, understand the note model, and choose the route that fits. You'll find the app links, official docs, and the written walkthrough in the companion guide. Start with understanding what stays private, then take the next step.
