GrokScan | Competitor to EthTrend by GrokAi

We asked GrokAi four main questions pertaining to the creation of a Tending Bot. This platform and token are the result of Grok's answers. Welcome to GrokScan.

At the heart of our platform is the Trending Bot, backed by the advanced capabilities of GrokAI, allowing you to strategically trend your token and amplify its visibility for a specified duration.
