Verifiable Price Oracle
Sentinel — Agent Trust Oracle's Team
Problem Statement
Traditional oracles require trusting the operator not to manipulate prices. A centralized price feed can be tampered with at any point — the operator can modify fetching logic, cherry-pick sources, or sign false data. There is no way for consumers to verify that the reported price was actually computed by the claimed code from the claimed sources. This oracle eliminates that trust assumption by running inside an EigenCompute TEE (Intel TDX), where code integrity is cryptographically proven, the signing key is enclave-isolated, and every price is attested on-chain via EAS for independent verification.
A TEE-secured cryptocurrency price oracle running on EigenCompute that fetches prices from 3 independent APIs (CoinGecko, DeFiLlama, DexScreener), computes outlier-resistant medians, and publishes verifiable EAS attestations on Base. The TEE is structurally necessary, not bolted on — without it, the oracle is just another centralized price feed. EigenCompute Intel TDX enclave cryptographically proves the exact Docker image that ran, the wallet signing attestations is derived inside the TEE and cannot be extracted, and anyone can verify on-chain that attestations came from untampered code.
