Charli3 Oracle Network

Decentralized oracle infrastructure delivering real-world data to Cardano smart contracts through both push and pull models. Charli3's oracle network bridges external data sources to on-chain applications with continuous monitoring, instant processing, and configurable delivery methods.

Oracle Models

Push-based Oracle: Automated data delivery with flexible update schedules and deviation monitoring. Configure automated data delivery with customizable heartbeat intervals and deviation triggers to receive data updates tailored to your specific use case. Features include custom heartbeat configuration (choose update intervals matching your protocol requirements), deviation triggers (threshold-based updates when data changes beyond set percentages), always active 24/7 monitoring, and direct chain read for accessing Cardano on-chain data. Ideal for DeFi lending protocols, automated market makers (AMMs), derivatives platforms, synthetic assets, and any application requiring regular, predictable price feed updates.

Pull-based Oracle: On-demand data request solution delivering validated real-world data exactly when your application needs it. Access fresh, validated data from multiple trusted sources through instant processing with automated collection and validation triggered by your smart contract's request. Features include protocol-triggered updates (your smart contracts trigger data updates automatically when needed), fresh market data (every request fetches current data from live sources), cost efficient pay-per-request model with transparent fee structure, real-time sub-minute data delivery, and no long-term commitments. Currently undergoing V2 upgrade for enhanced efficiency and reduced costs (Q1 2025 launch). Perfect for liquidation engines, settlement systems, occasional pricing checks, and applications with intermittent data needs.

Data Coverage

Market Coverage: Track any market pair with custom rules including cryptocurrency pairs, stablecoins, native Cardano tokens, and cross-chain assets. The oracle aggregates data from multiple trusted sources including DEXes (Minswap, SundaeSwap) and CEXes (Binance, Bitfinex).

Real-Time Token Data: Comprehensive on-chain information for Cardano native tokens through the Token API. Access current price information, market data, on-chain metrics, detailed token metadata, supply information, and historical data through a developer-friendly RESTful API interface.

Custom Data Integration: Integrate any API as a data source for specialized use cases beyond standard price feeds including sports/event data, IoT data, and custom oracle solutions.

Technical Integration

Streamlined integration with comprehensive documentation, ready-to-use smart contract templates, and code samples for rapid deployment on Cardano. The oracle uses CIP-compliant standards and integrates seamlessly with Cardano's eUTXO model through standardized request/response patterns.

Decentralized Network

Trust-minimized architecture with transparent reward distribution to node operators. The oracle network performs consensus validation from multiple sources before delivering data to applications, ensuring data integrity and reliability.
