Paying with crypto

Sirius accepts crypto only — via BTCPay Server, which is self-hosted and non-custodial. We never see your wallet seed.

Supported networks

Bitcoin (BTC) — on-chain
Lightning Network — for small invoices (top-ups, Plus)
USDT — TRC-20 and ERC-20
Monero (XMR) — optional, can be disabled per store

Step-by-step

Open the Billing tab in the IDE or at sirius-ide.com/app/billing.
Pick a plan → Buy.
The IDE opens a BTCPay checkout in your browser. Pay from any wallet that supports the chosen coin / network.
BTCPay sends a signed webhook to our backend. We verify:
- the BTCPay signature,
- that the invoice is in Settled state,
- that the paid amount matches the plan price (within rounding).
Your account’s token quota is topped up immediately.

If the webhook is delayed (network reorg, slow Bitcoin confirmation), the IDE polls GET /billing/invoice/{id}/status every ~5 seconds until the activation lands.

What you’ll see on chain

Each invoice generates a fresh address — you’ll never reuse the same deposit address between purchases. Our backend stores the BTCPay invoice id, plan, status, and timestamps. It does not store the on-chain address or your wallet identity.

Troubleshooting

Symptom	Likely cause	Fix
Payment sent, status still pending	Network confirmation slow	Wait, refresh; should land within ~30 min
BTCPay says “amount mismatch”	Underpaid by network fees	Pay the missing amount to the same address
502 from `/billing/invoice/create`	BTCPay store not configured	Email support — that’s on us
