Sonar by Echo

Executive Summary

Sonar by Echo issues $SONAR on Base as a token layer atop Echo.xyz, a real co-investment platform that lets retail investors "join private funding rounds for new startups or token projects alongside professional investing communities." The critical red flags are a fully anonymous team with zero public member information, and a complete absence of tokenomics documentation — no supply figures, no allocation breakdown, no vesting schedule, and no whitepaper to speak of. The underlying Echo.xyz platform is a genuine, operational deal-flow infrastructure with real startup and token deals, which is the only credible anchor here. Score: 24/100 — the token layer has none of the transparency required to invest, regardless of the platform's legitimacy.
