Try it live, freeYour USDC is locked in a smart contract, not sent to us. We can only collect it by delivering before 27 Oct 2026. If we miss it, you take it back yourself from My apps, no permission needed. We can also refund you any time. View the contract on BaseScan. This covers full payments for ready apps too: the funds are released to us when we deliver.
Promised delivery: 27 Oct 2026 (counted from payment).
Add-ons are not part of this payment. Once your app is delivered you can request them from My apps, and you only pay if you say yes to the quote.
The working app on your own wallet and git, one-click deploy, and the step-by-step guide that makes you the verifiable developer.
Reshape it entirely: new features, your flows, your brand end to end, integrations you need. We scope it with you.
The complete Private Vault app: people paid onchain create a private account and prove every payment in their own browser on Miden, so strangers see commitments instead of their income, with a paywall, owner console and vault assistant built in.
Every buyer gets the same finished app. Basic branding and copy changes come through a quick form.
Your admin side: revenue, paywall editor, users, rules and the agent log.
Referral and growth mechanics, switched on when you are ready to grow.
Private payments proved on your own device are free. People paid onchain every week pay for Pro tools, and small teams and DAOs pay a setup fee plus monthly for private treasuries.
Proving runs on the user's device at no compute cost to the owner. Miden network fees are small; check current terms before charging.
Prices are yours to set. Illustrative, not a promise of income.

Custom work from $300: your branding, a different payee flow, accountant integrations or a team treasury setup. Scoped on a call.
The recipe (how it is built, the data, costs, risks, build order, the pitch and the demo script) is unlocked when your app is paid in full.
Public chains made paying people easy and made everyone's income readable. A freelancer paid in stablecoins can have her rates, her clients and her rent added up by anyone with an explorer. People who simply want normal financial privacy, the kind a bank statement gives them, have few easy options that do not depend on trusting a server.
Miden itself provides private accounts, private notes and client-side proving, and its own wallet and SDK already let developers create accounts and prove transactions in the browser. Other privacy systems such as Aztec and Zcash shielded wallets also exist. Private Vault is not a new privacy mechanic. What it adds is packaging: a plain, owner-branded app on Miden that makes the private choices the default, shows side by side what you see and what a stranger sees, asks before any delegated proving, and builds a weekly habit around collecting notes. It is a builder-status app for Miden first, and the value is in the experience, not novel cryptography.

Make ordinary financial privacy the default for people paid onchain, proved on their own device, with nothing to trust but math they can check.
The stranger's view Every payment shows two windows: your screen and what an explorer shows. Seeing 'amount hidden' next to your real payment is the moment people get it.
Six seconds, on your desk A visible proof dial in the browser tab turns a hard idea into something you watch happen locally, which builds trust fast.
The Sunday glass check A weekly two minute ritual: collect incoming private notes and see a score of how many payments a stranger could read. People keep the streak.

Cost per use: unlocked when your app is paid in full.
Every private payment needs a recipient, and the recipient is invited to collect the note in their own vault. The share card ('0 of 31 payments readable by strangers') travels in freelancer and privacy groups. Being early in the first wave of Miden apps puts it on ecosystem lists when they go up.

Nine routes from one vessel. Tap a port to open its chart.
Most wallets send your activity to someone's server before it ever reaches the chain. Own Private Vault and you run a client side proving app on Miden from your own wallet and repo, which makes you one of the early verifiable builders on a young chain. The brand, the users and the onchain record of shipping are yours.
It will change. That is the deal with early chains: you get to be early, and you will need to update the app when the network upgrades. Watch the Miden release notes and budget an hour a month for updates.
Private accounts are not the same as mixing stolen funds. Keep a clear terms page, do not market it for hiding from law enforcement, and check your local rules if you plan to charge.
You do not need to. Private Vault arrives working, deployed from your own wallet with a written guide for every step. You will click, paste and fill in names. If you ever want a change you cannot make, the custom option or a freelancer can handle it, but the first launch needs no code.
Yes. The contract is deployed from your wallet on Miden, the code sits in your own git repo, and the name and brand are yours. DEPLOYR does not hold your keys or take a cut of what Private Vault earns. If you stop paying anyone tomorrow, the app keeps running on your wallet.
That is the most likely early outcome, and it is fixable. The paths below start with you as the first user, then ten real privacy minded crypto users you can name today. If ten people you message do not care after you have shown it to them, you have learned something useful in a week instead of a year.
Free accounts with paid extras: a pro tier for power users (saved contacts, scheduled private payments, export), and a setup fee for teams and DAOs that want private treasury accounts. This ladder is a target, not a promise.
Illustrative stages, not a forecast. Results depend on you and the market; nothing here is guaranteed.
