Yes, XferAPI uses TLS 1.3 encryption, implements OAuth 2.0 authentication, and maintains SOC 2 Type II compliance with comprehensive audit trails.

Powerful Features forModern Applications

XferAPI provides enterprise-grade distributed transfer capabilities with mathematical guarantees, automatic recovery, and battle-tested reliability patterns.

Official Account Isolation

Pre-defined official account ranges with negative balance support, isolated from user accounts for special business scenarios.

Separate official and user account management

Negative balance support for official accounts

Enhanced security through isolation

Flexible business scenario support

Perfect Zero-Sum Accounting

Mathematical guarantee that all account balances sum to zero at any time, providing powerful self-checking mechanisms.

Mathematical consistency guarantee

Powerful self-checking mechanisms

Simplified reconciliation process

Asset anomaly detection

Hotspot Account Avoidance

Dynamic distribution across official account ranges during transactions, effectively preventing hotspot account bottlenecks.

Dynamic account distribution

Prevents performance bottlenecks

Improved concurrent processing

Scalable transaction handling

Semi-Success State Support

Source account deduction completion marks semi-success, allowing target account additions to continue, significantly improving availability.

Improved system availability

Graceful failure handling

Continuous operation support

Reduced downtime risk

Sharding & Cross-Database

Built-in sharding capabilities supporting cross-database transactions, meeting large-scale business data storage requirements.

Horizontal scaling support

Cross-database transactions

Large-scale data handling
