Deposit credit policy
Decide when a deposit becomes usable: confirmation count, amount matching, first-time address review, or delayed credit for higher-risk users.
Custom Payment Flow
Custom Payment Flow
The standard WARMKEY gateway is the starting point. We reshape deposit credit rules, payout approval, risk controls, and system callbacks so the money flow matches your business — not a generic template.
When the default flow is not enough
Exchanges, GameFi, OTC desks, and platforms often need extra checks before crediting a user or releasing a payout. WARMKEY keeps non-custodial settlement, then layers your rules on top.
Payout approval path
Shape payouts around allowlisted addresses, maker-checker review, batch payout, daily limits, or delayed release after a cooling-off window.
Fit your existing stack
Connect the flow to your admin panel, finance tools, risk engine, or customer support process instead of forcing a one-size-fits-all callback.
Deposit
Inbound cashflow, rebuilt
Keep 1 user 1 address as the recognition layer, then customize how your system treats each incoming payment.
- Dedicated address assignment and reuse rules
- Exact-amount vs open-amount deposit matching
- Pending / confirmed / credited status mapping
- User notification, admin alert, and ledger posting
Payout
Outbound cashflow, under your rules
Payouts stay under merchant-controlled signing. We add the operational path your finance and risk teams actually need.
- Address allowlist and destination checks
- Maker-checker, batch payout, and cooling-off windows
- Per-user, per-day, or per-asset limits
- Cold-wallet signing with your existing approval habit

Limits, first-payout review, and unusual-amount holds.

FAQ
Do I have to use the standard WARMKEY deposit flow?
No. The standard 1 user 1 address gateway is the base. Custom work starts when your credit, payout, or risk rules need extra steps.
Will customization move funds into WARMKEY custody?
No. Settlement stays under merchant-controlled signing. We change the operational path, not the custody model.
Can deposit and payout be customized together?
Yes. Most clients need both sides of the cashflow aligned: when users are credited, and how payouts leave the business.
How do we start?
Share the current user journey, exception cases, and any system we must connect to. We then propose a flow before writing code.

If your deposit or payout path is more specific than a generic gateway, we can design it around your rules and still keep merchant-controlled settlement.
