A PROVEN, FOUR-PHASE PROCESS
Our Methodology: From Risk Assessment to Live Deployment
Our systematic approach ensures your compliant transaction sponsorship solution is secure, scalable, and integrated seamlessly with your existing compliance stack. We deliver a production-ready system, not just a proof-of-concept.
01
Phase 1: Compliance & Risk Assessment
We conduct a deep-dive analysis of your target jurisdictions, user KYC/AML requirements, and transaction monitoring rules. We map your policies to on-chain logic, identifying risk vectors and defining clear compliance boundaries before a single line of code is written.

Frequently Asked Questions on Compliant Sponsorship
Get clear answers on how Chainscore's compliant transaction sponsorship works, from deployment to ongoing operations.
We integrate directly with your existing compliance infrastructure via API. Our sponsorship layer acts as a policy enforcement point, intercepting transactions and validating them against your current KYC provider (e.g., Sumsub, Jumio) and sanctions lists in real-time. We support standard webhook and REST API integrations, with typical setup completed in under a week.
