This npm package provides a utilities to read the HODLer market's data and also utilities for transacting with a HODLer market.
npm i @definer-org/definer-hodlerUse the prebuilt dist/definer-hodler.min.js, or build using the definer-hodler-sdk git repository.
npm run buildInclude dist/definer-hodler.min.js in your html file. This will expose MarketDataReaderFactory, MarketTransManagerFactory and CHAINS object.

</html>CHAINS has all the chains supported on the Definer platform.
Note: For better performance the HODLer market data is fetched only once from the smart contract and stored in the object created. If the hodler market data needs to be refetched from the smart contract a new object would need to be created.
