Charli3

Charli3 is the first decentralized oracle network built specifically for the Cardano blockchain, founded in 2021. The company provides secure, trustless, and transparent data delivery infrastructure through advanced oracle networks with industry-leading reliability and performance.

Core Products and Services

Charli3 offers three primary oracle solutions and a developer SDK:

Push-based Oracle: Automated data delivery with customizable heartbeat intervals and deviation triggers. This solution provides continuous monitoring and automatic delivery of price feeds to smart contracts, with configurable update schedules based on time intervals or price movement thresholds. Ideal for DeFi protocols requiring regular, predictable data updates.

Pull-based Oracle: On-demand data requests that deliver validated real-world data exactly when applications need it. Operating on a pay-per-request model, this solution enables protocol-triggered updates for fresh market data while optimizing costs through instant processing without long-term commitments. Currently undergoing a major upgrade with enhanced efficiency planned for Q1 2025.

Charli3 Dendrite SDK: An open-source Python SDK (MIT License) that provides unified access to every major Cardano DEX through a single interface. Developers can build trading bots, DEX aggregators, and DeFi applications with minimal code, accessing liquidity pools, executing swaps, and tracking token operations across 8+ supported DEXs including Minswap, SundaeSwap, MuesliSwap, Spectrum, VyFi, WingRiders, GeniusYield, and Axo.

Cardano Token API: Real-time Cardano token data API for developers building on the Cardano ecosystem.

Key Strengths

Proven Security and Reliability: Charli3's multi-layered security architecture ensures 99.99% uptime with over 250,000+ on-chain updates, 100% ecosystem uptime, and 29,310+ continuous hours active. The platform has been audited by leading security firms including Certik and Anastasia Labs, with comprehensive infrastructure audits completed. Security features include outlier detection, multi-sig validation, tamper-proof delivery, and decentralized function.

Cardano-Native Design: Purpose-built for Cardano's unique eUTXO transaction model with native contract support, block-level synchronization, and CIP-compliant integration. This native design ensures optimal performance and seamless integration with Cardano's architecture.

Quality Data and Validation: Aggregates real-time price data from multiple trusted sources including DEXes (Minswap, SundaeSwap), CEXes (Binance, Bitfinex), and APIs (CoinGecko) for manipulation-resistant feeds. The platform's multi-source validation ensures data accuracy and reliability.

Developer-Friendly Integration: Streamlined integration with comprehensive documentation, ready-to-use code samples, and SDKs for rapid deployment. The platform provides a developer portal with active price feeds, detailed API documentation, and open-source repositories.

Notable Clients and Integrations

Charli3 powers major Cardano DeFi protocols including DripDropz, Moneta, VyFinance, SundaeSwap, MuesliSwap, Minswap, WingRiders, FluidTokens, Agent T, SteelSwap, and NEWM. The platform provides price feeds for numerous token pairs including ADA/USD, BTC/ADA, CHARLI3/ADA, and various native Cardano tokens.

Use Cases

DeFi Protocols: Secure and verified price feeds for trading platforms, lending protocols, and synthetic assets with reliable data aggregation.

Proof of Reserve: Verifiable reserve data for stablecoins and real-world assets with real-time validation and transparent tracking.

Enterprise Solutions: Secure data infrastructure for institutional adoption with vetted node consensus and trustless data streams.

Real World Assets (RWAs): Track digital tokens representing physical and traditional financial assets such as currencies, commodities, equities, and bonds.

Future Roadmap

Charli3's development roadmap includes: Architecture Audit (full security audit of operational systems), Pull Oracle V2 (upgraded on-demand data with lower pricing and increased efficiency), Expanded Node Network (increased decentralization), and Launch of Charli3 Partnerchain (migration to dedicated partner chain for operational efficiency and cross-network adoption). The platform is also developing a node operator network where participants can earn rewards while contributing to network security and reliability.
