# Precompiled contracts

### 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 ](/docs/build-on-kiichain/developer-tools/js-ts-sdk/kiijs-evm.md)to help interact with them.
