The Cardano ACTUS (Automated Contract Types Using Signals) framework is a set of rules and standards that define how smart contracts should be designed and implemented on the Cardano blockchain. It is intended to provide a standardized and consistent approach to smart contract development, helping to ensure the reliability and security of these contracts.

The ACTUS framework covers a wide range of financial contracts, including loans, bonds, and derivatives, as well as other types of contracts such as employment agreements and insurance policies. It includes guidelines for the design and execution of these contracts, as well as for the reporting and auditing of their performance. By providing a clear set of rules and standards, the ACTUS framework aims to facilitate the use of smart contracts in real-world financial applications and to help build trust in the Cardano blockchain as a platform for these contracts.
