EVM Oracle Adapter Development

overview

CORE SERVICE

Smart Contract Development

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

We architect and deploy custom smart contracts for DeFi, NFTs, DAOs, and enterprise applications. Our development process ensures security-first design, gas optimization, and comprehensive testing before mainnet deployment.

Security Audits: Every contract undergoes internal and third-party review using tools like Slither and MythX, following OpenZeppelin best practices.
Protocol Expertise: Specialized development for ERC-20, ERC-721, ERC-1155, and custom standards like ERC-4626 for vaults.
Full Lifecycle Support: From initial design and Solidity 0.8+ development to deployment, verification, and ongoing maintenance.

Deliver a battle-tested, audited contract suite in as little as 2-4 weeks, reducing your technical risk and accelerating your product launch.

TURNKEY INTEGRATION

What Our EVM Oracle Adapters Deliver

We build production-ready oracle adapters that connect your smart contracts to any off-chain data source with enterprise-grade reliability and security.

Multi-Source Data Feeds

Aggregate and verify data from multiple premium and decentralized sources (Chainlink, Pyth, API3, custom APIs) to ensure high-fidelity, tamper-resistant inputs for your dApp's critical logic.

Sources Aggregated

< 1 sec

Update Latency

Gas-Optimized Execution

Adapters engineered in Solidity 0.8+ with gas-efficient patterns, reducing on-chain computation costs by up to 40% compared to naive implementations for high-frequency data updates.

THE CHAINSCORE ADVANTAGE

Why Choose Custom Adapter Development

Generic oracles are a bottleneck. Our custom adapters are engineered for your specific data needs, unlocking new use cases and competitive advantages.

Protocol-Specific Integration

We build adapters for niche protocols like GMX, Synthetix, and Aave V3, not just price feeds. Access custom on-chain data like liquidity depth, collateral health, and governance parameters.

Gas-Optimized Execution

Reduce your dApp's operational costs by up to 40% with adapters written in low-level Yul or Huff. We minimize on-chain computation and storage for high-frequency data updates.

Multi-Source Data Aggregation

Mitigate oracle manipulation risks. We design adapters that pull and compute data from 3+ independent sources (APIs, other oracles, on-chain reserves) with customizable consensus logic.

Rapid Deployment & Upgrades

Go from specification to mainnet in under 3 weeks. Our modular architecture allows for seamless updates to data sources or logic without disrupting your production environment.

Formal Verification & Audits

Every adapter undergoes rigorous testing and formal verification using tools like Certora and Slither. We provide audit-ready code and comprehensive security reports.

24/7 Monitoring & Support

We don't just deliver code. Our team provides real-time monitoring, alerting, and incident response for your custom oracle infrastructure, ensuring 99.9% uptime.

The Infrastructure Decision for Your Protocol

Build vs. Buy vs. Chainscore Adapter

A clear comparison of the three main paths to integrate secure, reliable on-chain data into your EVM application.

Key Factor	Build In-House	Generic Third-Party	Chainscore Adapter
Time to Production	6-12+ months	2-4 months	4-8 weeks
Upfront Development Cost	$200K - $500K+	$50K - $150K	$25K - $75K
Security Posture	High Risk (custom, unaudited)	Moderate Risk (shared, audited)	Low Risk (bespoke, audited)
Data Source Flexibility	Full Control	Limited to Provider's Feeds	Custom Aggregation & APIs
Maintenance & Updates	Your team's ongoing burden	Provider's roadmap, your integration work	Managed service with optional SLA
Multi-Chain Support	Custom per chain (high cost)	Often limited or premium tier	Native support for 10+ EVM chains
Latency & Reliability	Your infrastructure's SLA	Shared public node performance	Dedicated RPCs & 99.9% Uptime SLA
Total Cost of Ownership (Year 1)	$300K - $700K+	$80K - $200K	$40K - $120K

PROVEN METHODOLOGY

Our EVM Oracle Adapter Development Process

A structured, security-first approach to building reliable data feeds that power DeFi, prediction markets, and on-chain automation. We deliver production-ready adapters, not just prototypes.

1. Architecture & Specification

We define the data source, update frequency, and security model. This includes selecting the optimal oracle pattern (push vs. pull) and designing gas-efficient data structures for on-chain storage.

1-3 days

Spec Finalization

Patterns Evaluated

2. Secure Smart Contract Development

Development in Solidity 0.8+ using OpenZeppelin libraries. We implement multi-signature control, circuit breakers, and upgradeability patterns (Transparent Proxy) from day one.
