For Payments

Payments, settled by the chain itself.

A Stripe-shaped REST API, settled on AsentumChain in five seconds. Charges, customers, checkout sessions, webhooks. Drop the SDK into any Node app and start billing — settlement happens on the chain underneath.

Quickstart

npm install @asentum/pay →API reference →/healthz →

One-shot charges

Charge an address. Get a webhook.

// One-shot charge — Stripe-shaped, settled on-chain.
import { Asentum } from '@asentum/pay';

const pay = new Asentum(process.env.ASE_SECRET);

const charge = await pay.charges.create({
  amount:      10_00,             // 10 ASE, minor units
  currency:    'ase',
  customer:    'cus_8XQ2…',
  description: 'Monthly plan',
});

// → charge.id      = 'ch_2Lp9…'
// → charge.status  = 'pending'
// → settles in < 5 seconds. webhook fires.

Idempotent. Replayable. Auditable from the explorer — every charge is just a transaction with metadata.

Recurring on-chain

Customer signs once. Cron does the rest.

// Recurring — the chain itself fires the next charge.
const session = await pay.checkout.sessions.create({
  mode:        'subscription',
  customer:    'cus_8XQ2…',
  price:       'price_premium_monthly',  // 10 ASE / month
  success_url: 'https://yoursite.com/welcome',
});

// Redirect customer → they sign once → done.
// ARC-21 cron handles every subsequent charge.

No keeper bot. No retry queue. ARC-21 native cron fires the recurring charge from inside consensus.

01SDK

Drop in the SDK. Migrate from Stripe in an afternoon.

Same resource model: charges, customers, checkout sessions, webhooks. Same idempotency keys. Same HMAC-signed payloads. The only thing that changes is the underlying settlement.

02CHAIN

Settlement in five seconds. Globally.

AsentumChain finalises every block in under five seconds. No multi-day international wires. No FX spread. The tx mines or it reverts — there is no "maybe" state to reconcile.

03CRON

Recurring without a keeper. Fired by consensus.

ARC-21 cron walks due subscriptions every block from inside the protocol. No Chainlink Automation. No Gelato. No retry queue to maintain. The recurring charge fires itself.

Why on-chain

The Stripe stack, without the Stripe stack.

Card-on-file billing has a 5–15% failure rate per cycle. International settlement takes 3–5 days. Chargebacks unwind months after the sale. Asentum Pay replaces all of it with deterministic on-chain settlement.
