Simulacrum is a platform that enables users to execute on-chain actions directly from social media platforms like X (formerly Twitter), utilizing their social media accounts as secure wallets. By leveraging Existential Attestations of External Media, Simulacrum creates a Synthetic Blockchain that allows users to broadcast transactions through social media posts. These publicly verifiable posts are indexed, validated by a network of validators, and then relayed to the Synthetic Blockchain for execution. This approach eliminates the need for traditional wallets and private keys, simplifying user interaction with blockchain technology. Additionally, Simulacrum's integration with AI agents facilitates the interpretation of natural language commands, further enhancing user accessibility.
