# ContractKit

Celo's ContractKit is a library to help developers and validators to interact with the Celo blockchain.

ContractKit supports the following functionality:

- Interact with json RPC API
- Send Transaction with celo's extra fields: (feeCurrency)
- Build apps to interact with governance and staking
