Scalable WebSocket API & Event Stream Management

We engineer robust, partitioned WebSocket streams and pub/sub architectures to reliably serve thousands of concurrent connections for live event data in prediction markets.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built to your exact specifications.

We architect and deploy custom Solidity smart contracts that form the immutable business logic of your application. Our development process is built on OpenZeppelin standards and rigorous security-first principles.

  • End-to-End Development: From initial spec to mainnet deployment, including ERC-20, ERC-721, and custom protocol logic.
  • Security Audits & Testing: Comprehensive unit/integration testing and formal verification with tools like Slither and Foundry.
  • Gas Optimization: Every contract is optimized for minimum execution cost, saving your users real money on every transaction.

Deploy with confidence. We deliver battle-tested contracts that power everything from DeFi pools to NFT marketplaces, ensuring zero critical vulnerabilities post-audit.

A REPEATABLE, PROVEN METHODOLOGY

Our Delivery Process: From Architecture to Deployment

We deliver production-ready WebSocket infrastructure through a structured, four-phase engagement model designed for speed, security, and scalability. This transparent process ensures you get a reliable, high-performance event stream API without the operational overhead.

01

1. Architecture & Design

We begin with a technical deep-dive to design a resilient, multi-chain WebSocket architecture. This includes defining subscription models, failover strategies, and data normalization schemas for protocols like Ethereum, Solana, and Polygon.

Deliverable: A comprehensive technical specification and system architecture diagram.

2. Core Infrastructure Build

Our engineers implement the core WebSocket gateway, event ingestion pipelines, and real-time data indexing. We use battle-tested libraries like ws and Socket.IO with custom logic for handling reconnections, rate limiting, and payload compression.

Deliverable: A functional, private staging environment with core streaming endpoints.
