Architecture

Technical architecture and design principles

Synthra is built on a modular, three-layer architecture designed for high performance and reliability.

System Layers

Application Layer - Handles user-facing operations including agent management, session control, and configuration.

Processing Layer - Manages context compression, rate limiting, and error handling for reliable message processing.

Integration Layer - Handles Solana blockchain, webhooks, and streaming connections for Web3 capabilities.

Core Components

Agent Manager

Primary interface for interacting with Synthra. Handles session lifecycle, message routing, and configuration.

Performance:

• Session creation: under 5ms
• Message routing: under 2ms
• Configuration updates: under 1ms

Session Manager

Manages isolated conversation contexts with automatic lifecycle management.

Tier	Max Sessions	Context Window
Free	10	4,096 tokens
Pro	100	8,192 tokens
Enterprise	Unlimited	32,768 tokens

Context Compression

Three strategies for managing context windows:

• FIFO - Removes oldest messages (under 10ms)
• Priority - Removes lowest priority messages (under 30ms)
• Semantic - Removes redundant content (under 50ms)

Rate Limiter

Token bucket and sliding window algorithms with sub-millisecond check time.

Message Processing

1. Rate limit check
2. Session lookup
3. Token counting
4. Compression (if needed)
5. AI processing
6. Response storage

Average Latency: under 100ms end-to-end

Security

• TLS 1.3 for all communication
• AES-256 encryption for stored data
• JWT-based authentication
• Role-based access control

Performance

Metric	Value
Requests/sec	10,000
Concurrent sessions	100,000
Message latency (p50)	45ms

Synthra does not store message content by default. Enable persistence explicitly via configuration.
