Now in early access
TLAY turns a connected device's actions into services that people and software can buy. Buyers pay into a contract, the device measures and signs what it delivered, and they are charged for exactly that. The rest goes back to them on its own.
The demo opens with a throw-away wallet and test money, so you can order, run a device and see the settlement. It resets every night.
No account to buy. A wallet signs in and signs the payment.
No gas for the buyer. The platform sends the transactions the buyer signed.
No money with the platform. A contract holds it until the order settles.

English narration with captions. The order, amounts and addresses in it come from a test run. For the long version, read the thesis.
How it works
A manifest lists what it can do, the inputs each action takes and what it measures. Your device maker writes it once per product.
The device signs a one-time challenge with its own key. From then on only your organisation can run it, or sell it.
Pick the action, the price and who gets paid, a site owner or installer included. List it in the market, or sell it to your own customers.
The device runs, meters and signs. The contract pays each payee their share of what was delivered and refunds the buyer the rest.
metered_service_escrow
The buyer pays in the most an order can cost. The device runs once, up to what was ordered, and the buyer is charged for what it measured. Every delivery can be accepted or disputed.
0.00001 USDC per ms, up to 5,000 ms
access_lease
One payment for the right to use the device for a while, a set number of times. The seller is paid when the access starts; the lease ends by itself.
0.005 USDC for 1 hour, up to 5 uses
access_subscription
Prepaid periods with a number of uses in each. The seller is paid period by period; a buyer who cancels gets the periods that have not started back.
0.002 USDC a day, 7 days, 10 uses a day
Prices are the sandbox's examples. Every service is priced by its seller.
Why trust it
Buyers pay an escrow contract on chain, never the platform and never the seller directly. Settlement credits each payee; sending it on can only go to the payee's own address.
Each run's meter readings and result carry the device's own signature, and the charge is computed from them. The evidence can be anchored on chain.
On your own address, every order waits for your key to sign its terms. Sign in the app with your wallet, or run the signer next to the key under rules you set.
A service names who decides a disputed delivery. Without a decision in time, the buyer gets everything back. The buyer's reason and both sides' messages are on the order.

For developers
A C runtime and ESP-IDF components for ESP32-C3 and S3: as the main controller, or as a module next to your own MCU. The device keeps its keys, signs its records, takes only firmware signed by your publisher key, and falls back if a new image does not start.
A REST API described in OpenAPI, with SDKs for TypeScript, Python and Go, webhooks with signed deliveries, and the same orders, disputes and notifications the apps use. Software can buy too, within a spending grant its owner signed.
// buy 1,000 ms of a machine's time, then run it
import { MceClient } from "@tlay/mce-platform-sdk";
const mce = new MceClient({ baseUrl, clientId, clientSecret });
const quote = await mce.quotes.create({
offering_id, quantity: "1000", buyer: { address: wallet },
});
const order = await mce.agreements.create({ quote_id: quote.id });
// the buyer's wallet signs the payment; once it is held:
await mce.invocations.create(deviceId, {
action: "leased_run", product_version: "1.0.0",
parameters: { duration_ms: 1000 }, expires_at,
agreement_id: order.id,
});Now: metered orders, leases, subscriptions and disputes work end to end, from the device's signed record to settlement.
Next: verification on production hardware, then opening to the first device makers and fleet operators.
We are onboarding device makers and fleet operators one by one ahead of launch. Tell us what your devices do; we will come back with how they could sell it.
