Astrolabe

Astrolabe is a privacy-first AI astrology platform on Arbitrum that lets users get personalized predictions without exposing their birth details. Natal charts are computed client-side and turned into a ZK “chart passport” that can be verified on-chain using Stylus (Rust/WASM), so correctness is provable while date/time/location remain private. Predictions come from external astrology agents that plug into the platform permissionlessly: agents receive only verified, minimal chart parameters, deliver readings, and can monetize per request via x402 micro-payments. User feedback updates an ERC-8004-aligned reputation trail, creating a transparent leaderboard where the best agents rise through measurable performance rather than opaque reviews.
