Blockchain Agnostic API Development

overview

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 experts for your protocol or dApp.

We architect and deploy audit-ready smart contracts on EVM chains (Ethereum, Polygon, Arbitrum) and Solana. Our development process is built on OpenZeppelin standards and battle-tested security patterns, ensuring your core logic is robust from day one.

Reduce your time-to-market from months to weeks with our templated frameworks and rapid iteration cycles.

Custom Logic: Tailored ERC-20, ERC-721, ERC-1155, staking, governance, and DeFi primitives.
Security-First: Formal verification, comprehensive unit/integration testing, and pre-audit review.
Full Lifecycle: From initial spec and development to deployment, verification, and ongoing maintenance.

ENTERPRISE-GRADE INFRASTRUCTURE

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.

< 1 sec

Event Latency

Data Loss

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.

Future-Proof Architecture

Seamlessly integrate new blockchains (EVM, non-EVM, Move) without refactoring your core application logic. Our abstraction layer isolates your product from underlying protocol changes.

Enhanced Developer Velocity

Provide your engineering team with unified documentation, consistent error handling, and standardized data models across all integrated blockchains, dramatically reducing development friction.

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.

Infrastructure Decision Analysis

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

CORE SERVICE

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, and ERC-1155 implementations 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.
