Signiq

Consumer Apps

Siqniq ($SGQ) is the utility token of Siqniq. It is a momentum intelligence agent for traders and builders that gets the early signals of a project in a noisy Web3 space. It aggregates activities from Github commits, onchain transactions and volume, X activities, Discord interactions etc and provides an overall score of the project based on how well each factor performs in the project. It is unique in the fact that unlike conversational AI that only looks into the surface level details to obtain the analysis, we scrape real-time data of a project and process it via a RAG system to truly give an actual score based on substantial information. $SGQ will be the token that users will stake to gain access to this premium AI analysis, use it for on-chain verification of a project score, which acts as a badge for that project. The token will also be utilized by our upcoming Momentum-as-a-Service API.
