About Credmark
Credmark is a data provider specializing in decentralized finance (DeFi). They curate and provide blockchain data through a suite of products designed for developers, data explorers, and quants. Their offerings include a free Token API for granular token data (prices, liquidity, holdings), a Portfolio API to trace wallet activity and risk, and a comprehensive DeFi API that allows users to run over 400 existing data transformations or build their own. For those needing direct access, Credmark provides raw blockchain data via the Snowflake Marketplace. The platform supports multiple chains including Ethereum, Polygon, BNB, Avalanche, Arbitrum, Optimism, and Fantom. A key feature is the transformation platform, which allows users to write custom models in Python, leveraging curated data sets and a library of pre-built models to accelerate development.
