Crypto Payments & Licensing

Accepting crypto should not turn your product company into a custody business. We build payment and licensing systems where funds go straight to addresses you control, and the software’s job stays narrow: detect payment, verify it, unlock access, keep records.

Three flows we build most often

One-time purchase → license key. A customer pays in ADM, BTC, ETH, or stablecoins; the system watches the address, waits for the confirmation depth you configure, then issues and delivers a signed license key. No processor between you and the funds.

Subscriptions without stored cards. Renewal invoices generated per period, grace windows, automatic downgrade on lapse. Crypto has no “charge the card on file” — we design the reminder and renewal flow around that honestly instead of pretending otherwise.

Access automation. A payment unlocks a Telegram group, Discord role, ADAMANT chat, API token, or feature flag — and revokes it when the subscription lapses. The dull parts (revocation, partial payments, refund bookkeeping) are where homemade systems break, so that is where we spend the effort.

What the architecture looks like

• Watch-only address monitoring — the payment server never holds spending keys
• Configurable confirmation depth per chain and per amount
• Signed webhooks into your backend, with replay protection
• Reconciliation reports so accounting can match every payment to an invoice
• Self-hosted deployment: your database, your customer records, your uptime

Reference platform

adamant-payment is our crypto-first platform for payments, subscriptions, and software license management. It is the starting point we fork and adapt — your project begins from running code, not a blank repository.

What to prepare before you start

• The chains and tokens you actually want to accept (fewer is better at launch)
• Where funds should land — cold wallet, multisig, or per-invoice addresses
• What a payment unlocks, and what must happen when it expires
• Your invoicing and record-keeping needs, so reports come out right from day one

We build, deploy, and maintain these systems in production — not slide decks.
