Testnet supported. ## Overview Ink is a cutting-edge L2 blockchain built on Optimism’s Superchain and released by Kraken. GoldRush offers the most comprehensive Ink 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 Ink 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.
