Developer SDKs

Reef for JS/TypeScript devs

We provide multiple libraries to interact with the Reef chain. reef.js can be used for both Substrate as well as EVM module interaction. An evm-provider.js wrapper around the reef.js strives to make the EVM module interaction easier - it is compatible with the ethers.js library. The hardhat-reef plugin goes a step further and allows to be used in the Hardhat framework - you can easily compile/deploy/interact with the contracts in a single project.

See the corresponding page describing JS libraries in detail.

Reef for Python devs

Developers can use our Python library to interact with Reef chain.
