Testnet supported. ## Overview Fantom is a fast, high-throughput open-source smart contract platform for digital assets and dApps. Founded in 2018, Fantom is designed to overcome the limitations of previous-generation blockchain platforms. Fantom is permissionless, decentralized, and open-source while achieving fast finality (1-2 second transaction confirmation) and low fees (\$0.00001). Furthermore, Fantom is EVM-compatible. Fantom code is completely open source. Anyone can read it, check on the progress, comment on it, and contribute. Fantom integrates industry-leaders oracle providers Chainlink and Band Protocol for maximum flexibility to access price feeds. GoldRush offers the most comprehensive Fantom Data API suite for developers, analysts, and enterprises. Whether you're building a DeFi dashboard, a wallet, a trading bot, an AI agent or a compliance platform, our Fantom Data APIs provide fast, accurate, and developer-friendly access to the essential onchain data you need. ### Supported APIs Access structured historical blockchain data across 100+ chains using REST APIs.
