# Overview Secret Network's CCL (Confidential Computing Layer) IBC Toolkit is a cross-chain messaging and confidential computation SDK for Cosmos developers. The toolkit allows Cosmos developers to build novel cross-chain applications such as: * **private DAO voting mechanisms** * **secure random number generation (Secret VRF)** * **confidential data access control via Secret NFTs** * **encrypted DeFi order books** * **and more!** Continue to [Cross-Chain messaging](https://docs.scrt.network/secret-network-documentation/confidential-computing-layer/ibc/basics/cross-chain-messaging-with-ibc-hooks) to learn how to use Secret Network's Confidential Computing Layer SDK , or dive into the Key value store tutorial [here](https://docs.scrt.network/secret-network-documentation/confidential-computing-layer/ibc/usecases/storing-encrypted-data-on-secret-network/key-value-store-developer-tutorial)🔥 --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
