Core Capabilities of Our Unified API
A single, robust API endpoint to interact with any major blockchain. We handle the complexity of multi-chain RPC management, node reliability, and real-time data indexing so your team can focus on building.
Multi-Chain RPC Abstraction
Seamlessly connect to Ethereum, Solana, Polygon, and 20+ other networks through a single, unified endpoint. We manage load balancing, failover, and rate limiting across our global node network.
Real-Time Event Streaming
Subscribe to on-chain events (transfers, mints, swaps) with WebSocket connections and webhook support. Get instant notifications for any contract activity without polling.
Enhanced Transaction APIs
Broadcast, simulate, and track transactions with advanced features like gas estimation, nonce management, and real-time status updates. Includes support for EIP-1559 and priority fees.
Historical Data & Indexing
Query historical balances, token holdings, and transaction histories for any wallet or contract. Our indexed data layer provides complex queries that raw RPC nodes cannot.
Enterprise Security & Compliance
SOC 2 Type II compliant infrastructure with private RPC endpoints, IP whitelisting, and audit logging. All data is encrypted in transit and at rest.
Business Outcomes for Your Team
Our blockchain-agnostic API development delivers measurable impact, accelerating your product roadmap and de-risking your infrastructure strategy.
Accelerated Time-to-Market
Deploy production-ready, multi-chain applications in weeks, not months. We provide pre-built connectors for 20+ major L1/L2 networks, eliminating the need for in-house protocol specialization.
Infrastructure Cost Reduction
Consolidate RPC node management, monitoring, and maintenance into a single, predictable API layer. Eliminate the overhead of managing disparate node providers and chain-specific tooling.
Enterprise-Grade Reliability
Guaranteed uptime with automatic failover across multiple node providers per chain. Built-in rate limiting, request queuing, and real-time health monitoring ensure consistent performance under load.
Security & Compliance Ready
Built with enterprise security standards: SOC 2 Type II compliant infrastructure, encrypted data in transit/at rest, and comprehensive audit trails for all blockchain interactions.
Build vs. Buy: Unified API Development
A detailed comparison of the costs, risks, and timelines associated with developing a multi-chain API in-house versus leveraging Chainscore's production-ready solution.
| Key Factor | Build In-House | Buy with Chainscore |
|---|---|---|
Time to First Production API | 6-12 months | 2-4 weeks |
Initial Development Cost | $250K - $500K+ | $0 (No upfront dev cost) |
Annual Maintenance & DevOps | $150K - $300K | Included in subscription |
Security & Audit Overhead | High (Requires external audit) | Included (Pre-audited, enterprise-grade) |
Supported Chains (Year 1) | 1-2 (Ethereum + 1 L2) | 15+ (EVM, Solana, Cosmos, more) |
Team Composition Required | 3-5 Senior Blockchain Engineers | Your existing backend team |
Uptime & Reliability SLA | Your responsibility (0% SLA) | 99.9% Guaranteed SLA |
Feature Updates (New Chains, RPCs) | Manual, lagging behind market | Automatic, always up-to-date |
Total Cost of Ownership (Year 1) | $400K - $800K+ | $60K - $180K |
Strategic Outcome | Diverts core team, high risk | Faster GTM, focus on product |
Our Development & Delivery Process
A transparent, four-phase methodology designed for CTOs who need reliable infrastructure, not just APIs. We deliver production-ready, secure endpoints with clear timelines and guaranteed SLAs.
Discovery & Architecture
We start with a deep technical dive into your use case, target chains, and performance requirements. We deliver a detailed architecture document covering RPC selection, failover strategies, and a 2-week implementation plan.
Secure Development & Integration
Our engineers build your custom API layer using hardened, open-source frameworks. We integrate multi-chain RPC providers (Alchemy, Infura, QuickNode) with load balancing, automatic retries, and comprehensive logging from day one.
Rigorous Testing & Security Audit
Every endpoint undergoes load testing (1k+ RPS) and security review against OWASP Top 10. We provide a full audit report and achieve 99.9% uptime SLA validation before deployment.
Deployment & Ongoing Support
We handle the full production deployment on your cloud (AWS/GCP) or ours, with 24/7 monitoring, alerting, and a dedicated Slack channel. Includes monthly performance reports and priority support.
Custom Smart Contract Development
Secure, production-ready smart contracts built to your exact specifications.
We architect, develop, and deploy custom Solidity or Rust smart contracts that form the foundation of your Web3 product. Our process delivers audit-ready code from day one, integrating best practices from OpenZeppelin and battle-tested security patterns.
From a 2-week MVP to a complex multi-chain protocol, we translate your business logic into immutable, efficient on-chain code.
- Token Systems: Custom
ERC-20,ERC-721, andERC-1155implementations with advanced features like vesting, staking, and governance. - DeFi Primitives: Automated Market Makers (AMMs), lending pools, yield aggregators, and derivative contracts.
- Enterprise Logic: Supply chain tracking, credential verification, and asset tokenization with custom access controls.
- Full Lifecycle Support: Development, testing (
Hardhat/Foundry), deployment, and post-launch monitoring.
Blockchain Agnostic API Development: FAQs
Get clear, specific answers to the most common questions CTOs and technical founders ask when evaluating a blockchain API development partner.
We follow a structured 4-phase delivery model: Discovery & Scoping (1 week), Architecture & Design (1-2 weeks), Development & Integration (2-4 weeks), and Testing & Deployment (1 week). For a standard multi-chain API gateway with 3-5 core endpoints, the typical time-to-production is 4-6 weeks. Complex protocols or extensive custom logic can extend this to 8-10 weeks. We provide a detailed project plan with weekly milestones.
