Build a mandate. Watch the on-chain account assemble.
Every VelaPay subscription compiles down to a single Solana account with deterministic fields. Adjust the terms below. The account layout on the right rewrites in real time — exactly as it would on the chain.
Authorize a mandate
Two surfaces. One protocol underneath.
Operators run the complete billing lifecycle from a hosted dashboard. Engineering teams integrate directly via the TypeScript SDK. Both surfaces call the same on-chain program — there is no proprietary state between them.
For operators
Configure plans, issue checkout links, reconcile revenue, and manage the full subscriber lifecycle without writing code. Every action in the dashboard is a signed, auditable on-chain transaction.
- Subscription plans on-chain
- Hosted checkout links
- Encrypted analytics
- Invoices + CSV export
- Team roles + 2FA
- Failed-payment retries
For developers
A fully typed SDK mapping one-to-one with the on-chain program. Generate instructions, sign transactions, verify webhooks, and validate mandates before submission. No intermediary state machine.
import { VelaPay } from "@velapay/sdk"; // 1. Create a plan on-chain const plan = await velapay.plans.create({ name: "Pro", amount: 29_000_000, // 29 USDC interval: "monthly", cycles: 12, }); // 2. Generate a hosted checkout link const { url } = await velapay.checkout.create({ plan: plan.id, success: "https://acme.com/welcome", });

SCOPED.
Every mandate is a sealed promise. Bounded in amount. Bounded in time. Bounded in who can act on it. Visible where it must be, encrypted everywhere else.
What the chain sees.
What it doesn't.
On a transparent chain, every settled subscription leaks commercial intelligence. VelaPay routes authorization through Arcium's MPC network — validators observe only the binary outcome.
Every billing model. One mandate primitive.
Subscriptions, metered usage, per-second streams, and agent budgets compile to the same authorization shape. One integration, every pricing model you will ever ship.
Subscriptions
Fixed-price recurring billing with on-chain cancellation rights. Plan migrations issued as amendment signatures.
Usage-based billing
Submit metered consumption on any cadence. Caps and overage logic live inside the mandate, not in code.
Per-second streams
Continuous settlement for compute, bandwidth, or time-based services. Cancellable atomically.
Agent mandates
Scoped budgets for autonomous agents. Vendor allowlists and daily caps enforced at the token layer.
Open stack. No proprietary lock-in.
VelaPay is a protocol on Solana, not a wrapper around it. Mandates live on-chain as open accounts. If VelaPay ceased to exist, your subscriptions would continue to execute.
