# Web3 SDK

Libraries and frameworks greatly simplify and speed up the development process

Use web3 SDK's to connect with blockchains, send and sign transactions, and more.

At the moment, only sets of methods described in [Ethereum API documentation](/blockchain-apis/ethereum-api.md) are available from API interfaces, when working through WatchData node, and we are actively working on adding new methods.
