Precompiled contracts

KiiChain has precompiled smart contracts crafted to allow EVM interaction with the Cosmos SDK functionalities

List of precompiles and their addresses

KiiChain supports both EVM JSON-RPC and Cosmos RPC interfaces. In order to easily interact with certain Cosmos modules, KiiChain has a set of precompiled contracts that can be called from the EVM.

Interacting with precompiles

You can utilize direct json-rpc connections to those addresses. We also have a TS/JS library to help interact with them.
