How does PayCoinPro handle funds?

PayCoinPro is a custodial payment gateway. Customer payments are credited to your merchant balance through an immutable double-entry ledger. Approved EVM payouts reserve the balance before signing and are reconciled through network finality.

What is the difference between Invoices and Deposit Addresses?

Invoices represent a priced payment intent with hosted checkout, expiry, and payment state. Payment Engine V2 allocates a destination for the selected payment method and retires destinations through an explicit lifecycle.

What cryptocurrencies and networks are supported?

Payment Engine V2 supports receiving on EVM-compatible networks, Bitcoin, and TRON. Automated sweeps and payouts currently operate on EVM-compatible networks. Available asset and network combinations are discoverable through the V2 assets endpoint.

How do I know which order a payment belongs to?

Each invoice has a stable identifier and your own order reference. When a customer selects a payment method, V2 snapshots the quote and allocates a destination. Confirmed payments and webhook events retain the invoice and order relationship.

How do I automate order fulfillment?

Use signed webhooks to listen for invoice events. V2 signs the timestamp and exact raw body with HMAC-SHA256, records delivery attempts, and retries through a durable outbox without rolling back the payment.

What are the fees for accepting crypto payments?

Pricing depends on the selected plan and processing volume. Review the current pricing page or contact the team for a commercial proposal. Network costs are shown separately from platform pricing where applicable.

How long does it take to receive payment confirmations?

Confirmation time depends on the selected network and its finality policy. V2 observes the transfer, waits for the configured confirmation threshold, handles reorgs, and only then applies the confirmed financial effect.

Do I need to complete KYC to use PayCoinPro?

Account and verification requirements depend on your environment, merchant status, and applicable compliance policy. You can use the sandbox to test an integration before requesting production access.

How do I integrate PayCoinPro with my website?

Create a V2 API credential, send an idempotent invoice request, direct the customer to hosted checkout, and verify signed webhook events before fulfillment. The generated OpenAPI contract documents the current request and response shapes.

Can I accept payments in stablecoins like USDT and USDC?

Supported stablecoin and network combinations are returned by the V2 assets endpoint. Availability is capability-driven so your checkout only presents combinations enabled by the current catalogue.

Is PayCoinPro secure?

V2 separates signing from the web application, reserves balances before payouts, signs webhooks with HMAC-SHA256, records administrative evidence, and reconciles movement through finality. PayCoinPro has not yet completed a third-party security audit.

ONE RELIABLE FLOW

Every handoff is explicit.

PayCoinPro keeps payment state, chain state, accounting, and delivery separate—so a retry never becomes a second financial effect.

01
Create an invoice
Send integer minor units and an idempotency key. V2 returns one invoice for one intent.
02
Let the customer pay
A hosted checkout presents an exact quote and a destination for the selected asset and network.
03
Wait for real finality
Overlapping scanners observe the transfer, match it, and advance only after the network policy is satisfied.
04
React with confidence
The ledger posts atomically, then the durable outbox delivers your signed webhook with retry history.

SECURITY BY STRUCTURE

Trust comes from boundaries you can explain.

Private-key operations sit behind an isolated signer boundary. Balances come from the ledger—not caches, provider responses, or webhook success. Administrative and payout decisions retain evidence for review.

The practical questions.

Which networks can receive payments?

Payment Engine V2 supports receiving on EVM-compatible networks, Bitcoin, and TRON. Automated payouts and sweeps currently operate on EVM-compatible networks.

How does PayCoinPro prevent duplicate charges?

Mutation requests use idempotency keys, and financial effects are protected by domain rules, database constraints, and an immutable double-entry ledger.

Can incoming funds be converted automatically?

The first supported conversion is optional native BNB to USDT on BSC. It is opt-in and off by default.

Is PayCoinPro non-custodial?

No. PayCoinPro is a custodial payment gateway. The platform operates receiving and movement infrastructure, while merchants control when and where approved payouts are sent.
