Merchant Stablecoin Payment Processor Integration

We build and integrate APIs that enable traditional e-commerce platforms and POS systems to accept stablecoin payments with real-time, automatic conversion to fiat for settlement.
Chainscore © 2026
overview
FULL-STACK ENGINEERING

Custom Blockchain Development

End-to-end development of secure, scalable blockchain applications tailored to your business logic.

We architect and build production-grade blockchain systems from the ground up. Our team delivers custom smart contracts, secure backend oracles, and scalable node infrastructure designed for your specific use case—whether it's DeFi, NFTs, enterprise supply chain, or identity management.

Deploy a secure, audited MVP in as little as 4-6 weeks, not months.

Our process is built for technical founders:

  • Protocol-Agnostic Design: We build on EVM (Ethereum, Polygon, Arbitrum), Solana, or Cosmos SDK based on your needs.
  • Security-First Development: All code follows OpenZeppelin standards and undergoes rigorous internal audits before third-party review.
  • Full Ownership: You receive 100% IP rights to the source code, deployment scripts, and infrastructure diagrams.

We move beyond generic templates. Our engineers implement complex features like gas-optimized batch processing, multi-sig governance modules, and real-time event indexing to ensure your application is performant and maintainable at scale.

Frequently Asked Questions

Common questions from CTOs and founders evaluating stablecoin payment infrastructure.

A standard integration for a single e-commerce platform takes 2-3 weeks from kickoff to production. This includes API integration, smart contract deployment, and end-to-end testing. Multi-platform or custom settlement logic can extend this to 4-6 weeks. We provide a detailed project plan in the first week.
