Features
Everything a crypto payment gateway needs. Nothing it doesn't.
LevinGate is a complete non-custodial stack — scanning, matching, quoting, checkout, notifications and reconciliation in one platform. Here is what that actually means, in detail.
Taking payment
The checkout and the money behind it
What your customer touches, and the engine that watches the chain while they pay.
Hosted checkout
A live payment page with a locked quote, QR code, copyable address and real-time confirmation progress — brandable per store with your logo and colors, or skippable entirely if you build your own flow on the API.
Locked quotes
The rate a customer sees is locked for a window when checkout opens. No moving-target pricing: the amount they pay is the amount you invoiced, with the quote recorded on the invoice.
Per-asset addresses
One address per asset per network — USDT-BEP20 and USDT-TRC20 are separate addresses. On EVM chains, addresses are verified by wallet signature before they go live; UTXO addresses are per-address scanned.
Every transfer watched
Scanners follow each chain block-by-block. Underpayments, overpayments, wrong-network and wrong-token transfers are detected and flagged — recorded with tx hash and amount, never silently miscredited.
Building the integration
An API designed to be wired into, not around
Clean REST from any backend — no frontend SDK required, no magic.
Developer-first REST
Predictable resources, cursor pagination on every list, and idempotency keys on writes so a retried request can never double-invoice. Create your first invoice in minutes with curl.
Signed webhooks
HMAC-SHA256 over a timestamp and the raw body, delivered on every state change with exponential-backoff retries, manual redelivery, and complete delivery history per endpoint.
Multi-store & multi-wallet
Run many storefronts under one account — per-store branding, payment methods, and a choice of shared merchant-level wallets or dedicated per-store receiving addresses.
Testnet-first environments
Every account gets test/live key isolation, and the platform runs against testnet chains (BNB Smart Chain testnet, TRON Nile, Sepolia, Bitcoin testnet4, Litecoin testnet4) so integration is risk-free.
Staying correct
Reconciliation and account hardening
The unglamorous parts that decide whether a payment platform is trustworthy.
Reconciliation built in
Missing, duplicate, late, underpaid, overpaid, wrong-asset and reorged payments are flagged with severity and a resolution workflow — with a full audit trail behind every resolution.
Hardened accounts
TOTP two-factor authentication, revocable sessions, API keys displayed exactly once at creation, and an append-only audit trail for every security-relevant action.
Non-custodial by design
Payments settle straight to your own wallet addresses. LevinGate never stores keys, never signs transactions, and can never freeze, sweep, or hold your funds.
Environment isolation
Testnet and mainnet are hard-separated at the data level — test keys never touch mainnet state, and mainnet chains stay off until an operator deliberately enables them.
Under the hood
The defaults you'll integrate against
No surprises in the fine print — these are the platform values your integration will see from day one.
- Default invoice TTL
- 30 minutes (merchant-configurable)
- BSC finality default
- 15 confirmations · ~3s blocks
- TRON finality default
- 20 confirmations
- Webhook signature
- HMAC-SHA256 · t=…,v1=… header format
- Webhook retries
- Exponential backoff · manual redelivery
- Underpayment tolerance
- 0–10% per store, decimal-exact
