Signalium leans on three layers of the 0G stack plus the Gimo Finance LST that runs on top of 0G Chain.

​
0G Chain (chainId 16661)

  • Hosts every market. MarketFactory deploys EIP-1167 clones of PredictionMarket plus a fresh Treasury and GimoAdapter per market in a single transaction.
  • Sub-second finality + cheap gas make per-market provisioning practical (~0.005 0G per market) and let bets feel instant.
  • The AIResolver contract verifies TEE provider signatures on-chain via ecrecover against an allowlist before forwarding to the market.

​
0G Compute (TEE)

Three roles share the same OpenAI-compatible inference endpoint, swapped in at runtime via the OG_COMPUTE_PROVIDER_URL / OG_COMPUTE_API_KEY config: Because the judge runs in TEE, the operator can’t quietly swap the model output. Only the allowlisted TEE provider key can produce a signature AIResolver accepts.

​
0G Storage

The judge prompt — the deterministic instructions the judge model will read at resolution time — is sealed to 0G Storage at market creation. Only its merkle root lives on-chain (in the market’s judgeStorageRoot field). At resolve time the worker pulls the full prompt back, runs the judge, and submits the resolution receipt’s merkle root as attestationHash. Anyone can re-fetch and audit.

​
Gimo Finance (StakePool at 0xAc06d1Df23a4Fa00981aFAC0f33A5936Bd2135aF)

Built on 0G Chain — StaFi LSaaS architecture. Native 0G in → st0G out; the rate appreciates over time. Each market’s Treasury owns a GimoAdapter instance that:
  • Calls stake(referrer) on deposit and holds st0G shares.
  • Calls unstake(lsdAmount) to start the ~3 day unbonding queue (3 eras × 86400s).
  • Calls withdraw() to claim matured tickets back as native 0G.
The API samples getRate() hourly and exposes a derived APY at /price/og-yield, which the bet panel uses to project the yield a market will earn between now and resolution. Until enough samples accumulate, the projection falls back to a 5% default that matches the SDK constant. See GimoAdapter for the full interface and edge cases.
