Tri Sigma (3σ)

Tri Sigma, styled as 3sigma (three sigma), was an autonomous AI agent deployed on the Solana blockchain in November 2024. The project framed itself around the statistical concept of a three-sigma event -- a rare, market-defining outlier -- and positioned its AI as a tool for detecting those moments before the broader market caught on. At its peak the token commanded a market cap exceeding 80 million USD and was listed on multiple centralized and decentralized exchanges. By mid-2025 the platform had gone dark. As of August 2026, the application server is unresponsive, the Twitter account (@tri_sigma_) shows no recent activity, and the TRISIG token trades near zero.
