Live mainnet rails

The crypto gatewaybuilt like a vault.

Accept BTC, ETH, USDT, USDC, SOL, and LTC. Invoice customers, credit a custodial ledger, and move funds with the same controls you expect from a serious payments desk.

Product

Payments in. Treasury out.

Most gateways stop at an invoice. CRYPDECK keeps going — a vault you can receive into, sweep from, and withdraw with policy.

Custodial vault

One ledger for receive, sweep, internal transfer, and live withdraw — not a spreadsheet of invoices.

Hosted checkout

Share a payment link with a QR and live status. No plugin required to take the first dollar.

Merchant API

Keys, IP allowlists, and CoinPayments-style engine routes for invoices, rates, and balances.

Signed webhooks

HMAC callbacks when a payment settles or expires. Retries are queued, not fire-and-forget.

Spend controls

TOTP, destination allowlists, daily limits, and dual approval before value leaves the vault.

Encrypted custody

HD keys stay envelope-encrypted. Production refuses default seeds, open registration, and fake deposits.

How it works

Three steps from quote to vault.

01
Create an invoice
Quote in USD. CRYPDECK issues a unique deposit address and locks the rate for the payment window.
02
Customer pays on-chain
Watchers confirm BTC, ETH, USDT, USDC, SOL, and LTC. Under and overpays settle by policy, not guesswork.
03
Credit the vault
Confirmed funds land in the merchant ledger. Sweep, transfer, or withdraw with MFA and allowlists.

Security

Designed to fail closed.

Production will not start with a default seed, simulated deposits, or an open registration door. Withdrawals require MFA and an allowlisted destination.

Encrypted HD custody envelope
RBAC for owner, admin, finance, readonly
Webhook SSRF guards and no-redirect delivery
Idempotent invoices and withdraws

“A payment page is not a treasury. CRYPDECK is both.”
Built for merchants who need CoinPayments-class rails without giving up the vault.
