Chain

Siri Chain is an innovative integration enabling Siri to directly interact with real-time blockchain data. This system leverages Siri’s voice capabilities to query and manage information from decentralized applications (DApps), providing users with a seamless, voice-activated blockchain experience. To make this interaction work smoothly, users need to add new custom shortcuts on their iPhones. These shortcuts enable quick access to specific Siri Chain actions, such as checking token balances, verifying transaction statuses, or even interacting with smart contracts in real-time. Through Siri Chain, users gain not only access to blockchain data on their iPhone but also the ability to automate frequent tasks and queries about their digital assets. By combining Siri with Siri Chain, the iPhone transforms into a personal blockchain assistant, simplifying access and control of decentralized information with the power of voice. In Siri Chain, three core actions are added to enhance interaction with blockchain data: sending payments, reading blockchain data, and writing data to the blockchain. These shortcuts empower users to conduct transactions, retrieve live information like balances or transaction histories, and even submit new data to the blockchain—all through simple voice commands. This functionality transforms Siri into a dynamic tool for blockchain management, streamlining tasks that traditionally require specialized apps or interfaces.

The Siri Chain app is built using Apple’s AppIntents framework, which allows us to integrate custom actions that Siri can understand and execute. With AppIntents, we create specific functions that link voice commands directly to blockchain operations, making it possible for Siri to interpret user requests related to reading, writing, and sending payments on the blockchain. At the core of the app is a wallet securely stored on the iPhone, which acts as the user’s personal key manager for signing transactions. This wallet stores the private keys necessary for secure blockchain interactions, ensuring that every transaction initiated through Siri is authenticated and authorized by the user. This setup allows users to send payments and interact with smart contracts while keeping their private keys safely on their device. The signed transaction is then broadcast to the blockchain, completing the process without leaving the iPhone.
