We deliver production-ready, secure, and scalable wallet and payment infrastructure, enabling you to launch stablecoin features in weeks, not months.
Stablecoin Wallet & Payment Integration
Core Integration Capabilities
Multi-Chain Wallet SDK
Pre-built SDKs for EVM (Ethereum, Polygon, Arbitrum) and non-EVM (Solana, Stellar) chains. Integrate custodial or non-custodial wallet features with a single API call.
Key Benefit: Reduce development time by 80% and support major blockchains from day one.
Stablecoin Payment Gateway
Seamless APIs for USDC, USDT, and EURC payments with real-time fiat on/off-ramps. Includes compliance checks, transaction batching, and sub-2-second settlement.
Key Benefit: Enable instant, low-cost global payments with built-in regulatory safeguards.
Compliance & KYC/AML Engine
Integrated identity verification (KYC) and transaction monitoring (AML) tools that meet global standards (FATF Travel Rule, MiCA). Configurable rule sets for different jurisdictions.
Key Benefit: Launch with confidence, knowing your payment flows are compliant by design.
Real-Time Analytics Dashboard
Monitor wallet activity, transaction volumes, fee revenue, and user growth in real-time. Export custom reports and set alerts for critical business metrics.
Key Benefit: Gain actionable insights to optimize your product and drive user engagement.
Dedicated Developer Support
Get direct access to our senior blockchain engineers via Slack. Includes architecture reviews, deployment support, and a 99.9% uptime SLA for all managed services.
Key Benefit: Accelerate your go-to-market with expert guidance and guaranteed reliability.
Business Outcomes & Value
Our stablecoin integration delivers measurable business results: faster time-to-market, reduced operational costs, and enhanced user trust through enterprise-grade security.
Rapid Integration & Deployment
Go live with a fully integrated, white-labeled stablecoin wallet in under 4 weeks. We handle the full stack—from smart contracts to frontend SDKs—so your team can focus on core product development.
Enterprise-Grade Security & Compliance
Deploy with confidence. Our integration architecture follows OpenZeppelin best practices, includes multi-sig treasury management, and is built for SOC 2 Type II compliance, mitigating regulatory and technical risk.
Reduced Transaction Costs & Friction
Cut payment processing fees by over 90% compared to traditional gateways. Our gas optimization and multi-chain routing ensure sub-cent transaction costs for end-users, removing a major adoption barrier.
Scalable Multi-Chain Architecture
Future-proof your payments. We build on EVM-compatible chains (Ethereum, Polygon, Arbitrum) with a modular design, allowing you to add new networks and stablecoins (USDC, USDT, DAI) without platform re-architecture.
Enhanced User Trust & Retention
Provide a seamless, non-custodial experience that users trust. Features like social recovery wallets, real-time fiat on/off ramps, and transparent transaction history increase engagement and reduce churn.
Dedicated Technical Partnership
Get more than a vendor—get a technical co-pilot. We provide ongoing support, protocol upgrades, and strategic advisory to ensure your payment system evolves with the blockchain landscape.

Our Delivery Process
A structured, client-centric methodology designed to deliver secure, production-ready stablecoin payment systems with minimal friction and maximum transparency.
Discovery & Architecture
We conduct a deep-dive technical workshop to define your payment flows, compliance requirements, and target chains. You receive a detailed technical specification and architecture diagram for sign-off.
Smart Contract Development
Our team builds and unit-tests the core wallet logic, payment routing, and multi-signature modules using audited patterns (OpenZeppelin) and gas-optimized Solidity. All code is documented and version-controlled from day one.
Security & Audit Integration
We integrate security from the start, preparing code for third-party audits (e.g., CertiK, Quantstamp). We conduct internal reviews and implement a formal remediation process for any findings.
Staging & Client Testing
We deploy the complete system to a staging environment (testnet) for your team to conduct UAT. We provide test scripts, faucet funds, and dedicated support to validate all payment scenarios.
Production Deployment & Handover
We manage the mainnet deployment, configure monitoring (alerting, dashboards), and provide comprehensive operational runbooks. The project concludes with a knowledge transfer session for your engineering team.
Technology & Protocol Stack
We build on battle-tested, audited protocols and infrastructure to deliver secure, scalable, and compliant payment solutions. Our stack is chosen for its reliability, developer ecosystem, and proven enterprise adoption.
Multi-Chain Smart Contracts
Deploy secure, gas-optimized ERC-20 stablecoin contracts on Ethereum, Polygon, and Arbitrum. Built with Solidity 0.8+ and OpenZeppelin libraries, featuring upgradeability patterns and comprehensive audit readiness.
Secure Wallet Infrastructure
Integrate MPC (Multi-Party Computation) and AA (Account Abstraction) wallets for non-custodial user security and seamless transaction flows. Eliminates seed phrase risks and enables gas sponsorship.
Real-Time Payment Rails
Leverage Layer 2 networks and off-chain transaction batching for sub-second payment confirmations and near-zero fees. Integrates with existing fiat on/off-ramps and payment processors.
Compliance & Monitoring Layer
Built-in integration with Chainalysis and TRM Labs for real-time transaction screening, AML checks, and regulatory reporting. Automated wallet whitelisting and blacklisting controls.
High-Availability Infrastructure
Deployed on AWS/GCP with 99.9% uptime SLA. Features automated failover, geo-redundant node clusters, and 24/7 monitoring with PagerDuty integration.

Frequently Asked Questions
Get clear answers on our process, security, and support for integrating stablecoin wallets and payment rails into your platform.
A standard integration for a single stablecoin (e.g., USDC on Ethereum) with core wallet features takes 2-4 weeks from kickoff to production deployment. Multi-chain support (e.g., adding Polygon, Arbitrum) or complex payment flow logic can extend this to 6-8 weeks. We provide a detailed project plan with weekly milestones during discovery.
