VerxePay Ledger
High-scale, PCI-DSS compliant cross-border payment routing engine.
The Bottleneck
The Challenge
A cross-border merchant service was experiencing high transaction failure rates (up to 8.5%) and average settlement delays of 72 hours due to legacy routing rules and inconsistent bank API payloads.
Techverxe Intervention
The Engineering Solution
Techverxe built an asynchronous transaction routing microservice using Go and Node.js, backed by a dual-ledger PostgreSQL state machine. Utilizing smart failover mechanics and localized bank rails integration, the system dynamically reroutes failed attempts within 400ms.
Measurable Outcomes
System Results & Deliverables
Reduced transaction failure rate from 8.5% to sub-1.2%.
Cut average settlement turnaround times from 72 hours down to 4 hours.
Achieved full PCI-DSS Level 1 compliance with zero visual data exposure.
Handles peak throughputs of over 120,000 transactions per minute cleanly.
