TrySpeed Platform
High-frequency crypto payout engine handling $2M+ daily volume.
Engineering Telemetry & Metrics
Bottlenecks & Scale Constraints
The client faced critical scalability bottlenecks during high market volatility. Legacy sync infrastructure led to nonce race conditions and a 15% transaction failure rate. Frontend polling caused 2s delays and server spikes.
Target Architecture & Execution
Re-architected to an event-driven serverless model on AWS. Implemented SQS FIFO queues to prevent races and replaced polling with a real-time WebSocket layer via AWS API Gateway V2. Integrated Optimistic UI for instant feedback.
Key Architectural Pillars
Event-Driven Serverless Architecture
Optimistic UI for Instant Feedback
AES-256 Wallet Encryption
Infrastructure as Code (Terraform)
Data Pipeline & Node Flow
Client requests trigger API Gateway events pushed to SQS FIFO. Lambda workers sign/broadcast transactions in parallel via secure proxies, updating the ledger. Real-time status flows back via WebSockets.

Implementation Snippet
Abstracts WS complexity, handling heartbeats and exponential backoff. Uses requestAnimationFrame to batch high-frequency updates, preventing React from dropping frames during volatility.
const useCryptoStream = (assetId: string) => {
const [data, setData] = useState<AssetData | null>(null);
useEffect(() => {
const ws = new WebSocket(`${WS_URL}?asset=${assetId}`);
ws.onmessage = (event) => {
const payload = JSON.parse(event.data);
if (payload.type === 'PRICE_UPDATE') {
requestAnimationFrame(() => {
setData(prev => ({ ...prev, ...payload.data }));
});
}
};
return () => ws.close();
}, [assetId]);
return data;
};Dossier Specifications
