Sent a payment link nobody claimed? Take it back. In Opacus, money sent as a link shows as waiting in your history until someone claims it. Changed your mind? One tap, and the link stops working and the money returns to your private balance, on any device.

Pay Ada, not a long address. After you pay someone's Opacus address, keep them by name. Next time, type Ada in Send, write "Ada, 1200" in a list of payments, and read "Sent to Ada" in your history. The names you keep stay in your browser and never reach the pool.

Split the dinner bill, privately. In Opacus, request the total, add what it was for and how many of you were there. Everyone gets the same link or QR code with their share, pays it privately, and you see who has paid.

Private, and still ready for your accountant. Download a statement of your Opacus account. Your accountant opens it without a wallet and sees every deposit, payment and cash-out with its amount, date and note, each line checked against the pool. A statement can't move money.

How do you know a private pool holds real money? Open the Opacus pool page, no wallet needed: what it holds of each asset, from how many wallets, and how many moves happen inside it each day, all read from Solana. Who paid whom, and how much, it never shows.

Get paid at @ yourname. Claim a short name in Opacus and anyone can pay you with it, in place of a long address. The name is public, like any handle. What people send to it, and what you hold, stays private.

Swap without leaving your private balance. In Opacus, turn SOL into a stablecoin and back in one tap. You see the quote first: what comes back, the price and the fees. The trade settles on a public Solana market, and no wallet of yours ever appears in it.

Wallet trackers follow every big move on Solana. A private balance gives them nothing to follow. Inside Opacus, what you hold and who you pay stay out of view, so your next move stays yours until you make it.

Give your AI agent money of its own, not your wallet. Through MCP, Opacus gives an agent its own private balance. You fund it, you set the most it may spend on any one payment, and it pays for the tools and data it needs, privately.

Pay the whole team at once. Paste the list from your spreadsheet into Opacus, one line per person: a name, an Opacus address or a link, and an amount. Everyone is paid privately and sees only their own pay. Close the page halfway and it picks up where it stopped.

Need to prove a payment? Make a receipt. Any Opacus payment can become a receipt link: the amount, who received it and when, checked against the pool. Payers keep one for their books, and the people they pay use one as proof of income. Every other payment stays private.

Show you have enough. Keep how much to yourself. Opacus proves your private balance holds at least an amount, on a date, for the person who asked. They open a link, no wallet needed, and see that and only that: never the figure, your history or your address.

"October salary." "Rent, flat 3." "Thanks for the lift." Every Opacus payment can carry a short note, and only the person you pay can read it. It travels with the payment, privately, and from the outside nobody can even tell there is one.

A friend owes you for the concert tickets? Ask for it in Opacus: pick the amount, add a note and send the link, or show the QR code. They open it with their phone's camera and pay you privately. What friends owe each other stays between friends.

Send an invoice as a link. In Opacus, ask for an amount and add a note like "Invoice 42". Your client opens the link or scans its QR code and pays you privately in SOL or stablecoins. The invoice and the payment stay between the two of you.

Who you buy from is part of your edge. With Opacus, a business pays its suppliers, partners and contractors from a private balance. Competitors watching the chain learn nothing about who you work with, what you pay them or what you hold.
