GATEWAY TYPES
Crypto Payment Gateway Types We Build for iGaming, Fintech and Commerce Teams
OmiSoft scopes each gateway to the operator's custody model, compliance surface, and settlement requirements — the architecture, chain selection, and integration layer are defined by your use case, not a template.
Self-Hosted Non-Custodial Gateway
A non-custodial gateway never holds your funds — incoming payments go directly to wallet addresses you control. The gateway software monitors the blockchain, confirms transactions against invoices, fires webhooks, and updates balances without any intermediary holding period. Zero counterparty risk, zero account freeze exposure. The right architecture for operators who want full custody of their payment flow and no dependency on a third-party financial infrastructure to keep processing.
Included functions
Custodial Hosted Gateway
A custodial gateway holds incoming crypto on behalf of merchants before settlement — providing a managed treasury layer between incoming player/customer payments and outgoing fiat or stablecoin transfers. The operator controls the settlement schedule, conversion logic, and risk rules. This is the standard architecture for payment service providers, crypto PSPs, and gaming platforms that want to offer payment processing as a managed service to their merchants.
Included functions
White-Label Multi-Tenant Gateway
A white-label multi-tenant gateway allows the operator to onboard sub-merchants under their own brand — providing crypto payment processing as a service without exposing the underlying infrastructure. Each merchant operates in an isolated account with separate wallets, transaction ledgers, and API keys. The operator controls merchant onboarding, compliance tiers, and fee structures. Standard architecture for crypto PSPs and payment facilitators entering the market.
Included functions
API-Embedded Payment Module
Payment functionality delivered as a clean API layer inside an existing SaaS product, marketplace, or platform — without the host application becoming a licensed financial entity. The regulated and custody layer sits at the infrastructure level; the product team accesses deposit, withdrawal, and balance functions via REST API and webhooks. The right architecture for marketplaces running crypto payouts, vertical SaaS platforms adding payment rails, and B2B tools that need stablecoin settlement without building a standalone gateway.
Included functions
iGaming-Optimized Gateway
Purpose-built for casino and sportsbook operators who cannot use traditional card processors. TRON/TRC-20 is the settlement layer of choice — 3-second block time, sub-$1 fees, and USDT as the de facto player deposit currency. The gateway integrates with the platform's player wallet, handles instant deposits and withdrawals, and includes automated KYC/AML controls that meet licensing requirements without adding friction to onboarding. Settlement happens in stablecoins to eliminate volatility, with crypto-to-fiat conversion available as an operator option.

Core Features
Crypto Payment Gateway Features That Support Security, Compliance and Scale
Payment systems fail in predictable places — KYC flows that leak, settlement engines that drift under load, compliance added after the product ships. These four areas are where we build differently.
KYT/AML Transaction Monitoring
Automated KYC/AML processes integrated at the payment layer — not bolted on post-launch. Incoming transactions are screened against sanctions lists and watchlist feeds in real time. On-chain analytics flag high-risk addresses, mixer outputs, and darknet-adjacent wallets before funds reach the operator's balance. Risk-scoring rules are configurable by your compliance team without engineering involvement. FATF Travel Rule exchange is supported for cross-VASP transfers.
Multi-Chain Payment Router
Per-invoice address generation across supported chains — BTC, ETH, TRON, Solana, and EVM-compatible networks — with confirmation monitoring at the infrastructure level. The router detects incoming transactions against active invoices, validates confirmation counts against configurable thresholds, and fires webhook events as blockchain state changes. Rate lock at payment initiation prevents underpayment caused by price movement between invoice generation and confirmation.
Settlement & Volatility Protection Engine
Settlement decisions are explicit, never automatic. Operators choose between holding received crypto, converting to stablecoins — USDT, USDC — at confirmation, or batching fiat conversion on a schedule. Rate lock at invoice generation pins the expected payment amount — customers pay a fixed crypto equivalent at checkout, not a moving target. Cross-border settlement runs via stablecoin rails, bypassing SWIFT latency and correspondent banking overhead.
Merchant API & Operations Dashboard
Full REST API with comprehensive webhook coverage — payment received, confirmed, settled, and failed events produce structured callbacks with retry logic. Invoice management, payout scheduling, and reconciliation reports are available through the operator dashboard without engineering involvement for routine operations. Transaction ledgers are append-only and immutable — every state change has a timestamp and audit trail available for compliance review.

Payment Architecture & Settlement Design
The settlement engine is the financial source of truth for everything the gateway does — every deposit, every withdrawal, every reconciliation event. We design custody models, settlement schedules, and conversion logic before writing a line of application code. Architecture decisions cover wallet infrastructure type — hot, cold, or MPC — rate-lock mechanics to prevent underpayment, and fiat off-ramp integration where stablecoin-only settlement is not sufficient. The system survives chain congestion, provider outages, and retry storms without producing duplicate payouts or missed credits.
KYC / AML Integration
We integrate identity verification vendors and on-chain analytics tools into the payment flow and configure automated KYC/AML processes for ongoing transaction monitoring. This covers document verification and biometric liveness at onboarding, real-time KYT screening on incoming transactions, PEP and sanctions watchlist checks, and risk-scoring rules that your compliance team can tune without engineering involvement. Onboarding flows are calibrated to pass licensing authority review without the friction that collapses conversion rates at deposit.
Multi-Chain & Stablecoin Integration
Production integration across supported chains — BTC, ETH, TRON, Solana, and EVM-compatible networks — is built on our cryptocurrency development infrastructure, with per-invoice address generation, confirmation monitoring, and balance accounting handled at the infrastructure level. Stablecoin support — USDT TRC-20, USDT ERC-20, USDC — is a first-class feature, not a bolt-on: settlement, payouts, and operator treasury management can all run on stablecoin rails from day one. Chain selection is scoped during architecture design against your user geography and transaction volume targets.
Merchant API & Dashboard Development
The merchant-facing layer covers a REST API with full webhook coverage for payment lifecycle events, an operator dashboard for transaction monitoring, payout scheduling, and reconciliation, and sub-merchant management for white-label deployments. API documentation is delivered as an OpenAPI spec. Sandbox environment for merchant integration testing is included in the engagement. We handle end-to-end delivery — API design, dashboard build, documentation, and integration support — without separating the backend and frontend into separate contractors.
Security & Compliance Infrastructure
Security is designed into the architecture from the first infrastructure decision, not applied as a post-launch audit. Hot wallet exposure is minimized through cold storage thresholds configured at the architecture stage. TLS 1.3 for all data in transit, AES-256 encryption at rest, and audit-ready logging configurations are standard — not line items on a change request. For DeFi-style gateway flows, settlement via smart contract rails is scoped together with contract audit requirements, access control, and failure-state handling. Penetration testing scope and access control design are included in the engagement. For operators pursuing licensing, we document the compliance architecture in a format suitable for regulator review.

TAILORED SOLUTIONS
Crypto Gateway Architecture: Self-Hosted, Custodial, White-Label and iGaming-Optimized
Custody model choice determines everything downstream: your regulatory footprint, your settlement options, your compliance surface, and how fast you can ship. Getting this decision right at the start is the difference between a gateway that scales with your business and one that needs to be rebuilt when your volume grows.
Why Teams Choose OmiSoft for Crypto Payment Gateway Development
The team building your gateway has shipped a production crypto payment gateway for a global iGaming operator. Every problem you'll face — a KYC flow that converts at deposit but survives compliance review, a settlement engine that holds under high-frequency betting volume, a multi-chain router that handles chain congestion without stuck transactions — is a problem we've already solved for another client. We bring those decisions to the first architecture call, not to a retrospective six months into the project. The payment gateway practice sits within a broader fintech software development offering — the same engineering standards apply across the full fintech and crypto stack.

FAQ
Frequently asked questions
How do I hire crypto payment gateway developers for my project?
The process starts with a technical scoping call where we review your custody model preference, target markets, compliance requirements, and chain selection. From that call we produce a scoped proposal covering architecture, timeline, and fixed pricing — typically within five business days. Engagements run with a dedicated team of 3–5 engineers depending on scope, with a technical lead as your primary contact throughout. All source code and IP transfers to you at delivery.
How long does it take to build a crypto payment gateway?
A single-chain MVP gateway — self-hosted non-custodial or basic custodial architecture with KYC integration — typically ships in 8 to 12 weeks from contract to production deployment. A production multi-chain gateway with stablecoin settlement, full KYT/AML stack, and white-label multi-tenant architecture runs 12 to 18 weeks. Enterprise PSP platforms with multi-jurisdiction compliance and MPC wallet infrastructure are scoped individually. We provide a scoped timeline estimate before any contract is signed.
How much does crypto payment gateway development cost?
Crypto payment gateway development starts at $25,000 for a single-chain MVP with basic KYC integration and webhook-driven payment notifications. Production multi-chain gateways with stablecoin settlement, automated KYT monitoring, and white-label architecture typically start at $65,000. Enterprise PSP platforms with multi-jurisdiction compliance, MPC wallet infrastructure, and SLA-backed support are scoped individually. All pricing is delivered as a fixed-scope proposal after a technical discovery session — not an hourly rate estimate.
What compliance standards does a crypto payment gateway need to meet?
Requirements depend on the custody model and target jurisdictions. Custodial gateways that hold funds on behalf of merchants qualify as Virtual Asset Service Providers under FATF Recommendation 15 — which triggers AML program requirements and FATF Travel Rule obligations — Recommendation 16 — for cross-VASP transfers. In the EU, MiCA requires CASP authorization from national regulators. US-based custodial models require FinCEN MSB registration plus state-level money transmitter licenses. Self-hosted non-custodial architectures reduce the operator's compliance surface significantly. We identify the full compliance footprint during technical discovery and design the architecture to minimize scope from the start.
What is the difference between custodial and non-custodial crypto payment gateways?
A non-custodial gateway never touches your funds — incoming payments go directly from the customer's wallet to a wallet address you control. The gateway software observes the blockchain and fires events without any intermediary holding period. Zero counterparty risk, lowest regulatory overhead. A custodial gateway holds incoming crypto on behalf of merchants before settlement — enabling managed treasury operations, fiat conversion, and scheduled payouts that non-custodial architectures cannot provide. Custodial models carry VASP/AML obligations in most jurisdictions. The right model depends on your use case, volume, and regulatory position — we scope this at the architecture stage, not after the payment flow is built.
Can you build an iGaming crypto payment gateway?
Yes. We have production experience building crypto payment infrastructure for iGaming operators. The standard iGaming gateway architecture uses TRON/TRC-20 stablecoin settlement — USDT — as the primary rail — 3-second confirmations, sub-$1 fees, and instant player balance credit. For operators building on a Web3 casino platform, we integrate the gateway with player wallet systems, configure automated KYC/AML processes calibrated for gambling transaction patterns, and design the compliance documentation for licensing authority review. Gateway access for players who prefer to pay with Bitcoin, Ethereum, or other assets is supported alongside the primary stablecoin rail.
Who owns the source code after delivery?
The client holds full ownership of the source code and all intellectual property delivered during the project — gateway architecture, settlement engine, merchant API, smart contracts, and operator dashboard. You receive the full codebase, not a licensed deployment. You can modify it, extend it, or hand it to a different team without restriction. This is written into the contract before work begins.
