EVM Oracle Aggregation Development

Integrate and aggregate data from 10+ premium and decentralized sources (Chainlink, Pyth, API3, custom APIs) into a single, robust on-chain feed. Mitigate single-point failures and enhance data reliability for critical financial operations.

Custom-built aggregation logic and consumer contracts written in Solidity 0.8+ with OpenZeppelin standards. We implement advanced patterns like commit-reveal and signature verification to minimize gas costs by up to 40% for end-users.

Every oracle system undergoes rigorous security review. Our development process includes formal verification, unit/integration testing, and audits by leading firms like CertiK or Hacken before mainnet deployment.

Deploy consistent, verifiable data feeds across any EVM-compatible chain (Ethereum, Polygon, Arbitrum, Base, etc.). We manage the full deployment lifecycle, from testnet validation to mainnet launch and monitoring.

Proactive 24/7 monitoring of data freshness, deviation thresholds, and node health. Get instant alerts for anomalies via Slack, PagerDuty, or webhook to ensure your application's data integrity is never compromised.

Need a feed for a novel asset or complex calculation? We design and implement custom aggregation logic for RWAs, volatility indices, or cross-DEX pricing, tailored to your specific business logic and risk parameters.

Mitigate single-point-of-failure risks with a multi-source aggregation layer. We implement decentralized data sourcing, on-chain verification, and fallback mechanisms to protect your protocol from oracle manipulation and downtime.

Achieve sub-second price updates with outlier filtering and weighted median calculations. Our architecture ensures your protocol reacts to market movements with precision, reducing arbitrage opportunities and slippage.

Eliminate the overhead of managing multiple oracle integrations. We provide a unified, gas-optimized interface, handling data sourcing, aggregation logic, and upgrade management so your team can focus on core product development.

Rapidly launch markets for long-tail assets with custom price feeds. Our flexible framework supports any asset with sufficient liquidity, enabling you to capture new opportunities without being constrained by mainstream oracle providers.

Build user trust with fully verifiable data trails. Every price update includes cryptographic proof of its source and aggregation, enabling independent verification and aligning with the decentralized ethos of Web3.

Designed to handle your protocol's scaling from testnet to mainnet and beyond. Our systems support high-frequency updates across multiple EVM chains (Ethereum, Arbitrum, Polygon, Base) without performance degradation.

We define your oracle's data sources, aggregation logic, and on-chain/off-chain architecture. This includes selecting optimal Layer 2s, finalizing security models, and creating a detailed technical spec for stakeholder approval.

Our engineers build gas-optimized, upgradeable smart contracts in Solidity 0.8+. We implement battle-tested patterns from OpenZeppelin and Chainlink, focusing on modularity, pausability, and multi-signature access control.

We develop the off-chain node service that fetches, validates, and aggregates data from multiple sources. This includes building a resilient API, implementing consensus mechanisms, and setting up secure signing workflows.

Every component undergoes rigorous internal testing and a formal audit by a third-party security firm. We deliver a comprehensive audit report and implement all critical recommendations before mainnet deployment.

We handle the full deployment lifecycle across testnets and mainnet (Ethereum, Arbitrum, Polygon, etc.). This includes configuring oracles, setting up monitoring dashboards, and providing integration SDKs for your dApp.

Post-launch, we provide 24/7 monitoring, alerting, and dedicated technical support. Our team ensures high availability, handles data source updates, and assists with scaling or adding new oracle feeds.
