Core capabilities
Built for platforms that hold user balances
You run the business. PQPA handles collecting, sweeping and paying out.
A dedicated deposit address for every user
Not a throwaway address per order, but a permanent address for each of your users. They can deposit any time; we detect the payment, notify you, and you credit it to your own balance system.
- Addresses never expire — users don’t need a new one each time
- Webhook on arrival, plus lookup by record ID
- Built for platforms that keep user balances
Crediting, sweeping and payouts on autopilot
Deposits are swept into your collection wallet automatically, with gas topped up whenever an address runs short. Withdrawals go out in batches, and failed jobs recover on their own or can be retried in one click.
- Automatic gas top-up and sweeping
- Batch withdrawals in a single request
- Inspect and re-send webhooks from the dashboard
Hosted by default, Enterprise plan supports private deployment
Go live quickly on our hosted service. Private keys are stored encrypted, the master key is kept separate from the database, and nothing sensitive is written in plain text. Need it in your own environment? The Enterprise plan supports private deployment.

Security
Security comes first
Segregated accounts
Separate books per merchant and per app, so funds from different business lines never mix.
Payout and collection wallets kept apart
Payout and collection wallets are separate, so large balances never sit in the wallet used for payouts.
Two-factor sign-in
Dashboard sign-in supports a second factor via Google Authenticator.
Audit trail
Key dashboard actions are logged, so you can see who did what, and when.
Deposit risk flags
Deposits are tagged by risk level (KYT screening), so suspicious funds stand out at a glance.
Signed, replayable webhooks
Webhooks are signed with HMAC-SHA256 so you can verify them, and any you missed can be re-sent.
FAQ
How much does it cost?
You pay a plan fee in USDT, starting at 149 USDT/month for Starter. Each plan includes a monthly transaction allowance, with a per-transaction fee beyond that. We never take a percentage of volume. See the pricing page for details.
How fast are deposits credited?
It depends on the network’s block time and the confirmations required. As soon as a deposit is confirmed on-chain, we send you a webhook.
Do you hold our funds?
Deposits land on addresses allocated to your app, are swept to the wallet you designate, and payouts are sent from your own payout wallet.
Can we self-host?
Yes. The Enterprise plan supports private deployment. Book a demo and we’ll walk through it.
Which networks and tokens are supported?
BNB Chain (BSC), Polygon, TRON and Solana are live, with USDT and USDC. More networks are on the way.
