Sovereign Wallet
One widget holds the three things you may own in the ecosystem: your cloud credits, your Engramm licence, and your on-chain identity. This is also where you check your licence status, any time.

Reading it
- Licence status — the card at the top says it plainly (no licence here), with a Demo mode to peek at what a licence feels like.
- Sovereign identity — your public pseudonym in the ecosystem, a citizen's badge, unlocked by activating your Engramm licence.
- Infinity Credits — the balance with nothing hidden: 5.83 used / $31.00 — what you bought, what you burned, what's left, one bar.
- On-chain wallet — a real wallet on Base (USDC · ETH), with its address, an explorer link, and the Private key and Privacy folds right below. Yours, on your machine.
Adding credit

Three roads — one live, two honestly marked Soon right in the UI: card via Stripe's hosted checkout (25 / $50), USDT on Base, and credit codes. Pick an amount and the confirm screen states the contract in four dashes:

Payment opens in your browser, outside Mnemosyne OS. — Handled by Stripe. Your card details never reach this app. — Your balance updates a few moments after you pay. — No analytics, no trackers in the app.
The checkout itself is Stripe's, in your browser — currencies, Apple Pay, the works — and the app only ever learns that the balance grew:

The licence — two doors
- Buy the license · $70 — straight through.
- Free License — ask for one. The form is the same human pattern as free credits: tell the founder who you are and how you'll use Mnemosyne — reviewed by hand, activated on-chain.

The fastest way to get unlocked: join the Discord and say hi after sending the request — the founder is there.
The Engramm licence
The licence has a name: the Engramm. One purchase, no subscription — and true to the house, it doesn't live in a database of ours: it's activated on-chain, tied to your wallet. Your licence is yours the way your memory is.
Once active, the status card says it all — lifetime, verified on-chain:

And the pseudonym is claimed — with the line that sums up the whole identity model:

Your published apps display this name; your wallet stays the signature.
What it unlocks, notably:
- Your public pseudonym — the citizen's badge, claimed once, yours across the ecosystem.
- The advanced voice engines — the full Calliope range.
- Several store apps at once — without a licence you try cartridges one at a time, uninstalling to install the next; licensed, install freely — and external cartridges become unlimited.
- Create and publish — the creator door opens: build cartridges and publish them to the Hub.
