quanta-hello

A pay-per-use hello-world package, powered by Quanta on Arc. helloWorld() and greet(name) are ordinary functions — but each call first settles a sub-cent USDC nanopayment to the author via Circle Gateway (gas-free, on Arc), then runs.

Install

export QUANTA_BUYER_PRIVATE_KEY=0x<your funded Arc wallet key>
npm install quanta-hello

Install is free — it only checks a payer wallet is configured.

Use

const { greet, helloWorld } = require("quanta-hello");

(async () => {
  console.log(await helloWorld());   // pays 0.001 USDC, then → "Hello, World! 🌍"
  console.log(await greet("Arc"));   // pays 0.001 USDC, then → "Hello, Arc! 👋"
})();

Each call is one nanopayment to the author. Settlements appear on the author's dashboard.
