API3 (First-party oracles with built-in OEV recapture ) versus Chronicle (Gas-efficient, fully verifiable oracle born inside MakerDAO ) — how they differ on type, coverage and what they’re built for.
| API3 | Chronicle | |
|---|---|---|
| Type | Push + OEV | Push |
| Update model | Data providers run their own Airnode (no middlemen). The OEV Network auctions the value of each oracle update back to the dApp instead of leaking it to searchers. | Scribe: Schnorr signature aggregation decouples validator count from verification cost, so updates stay cheap as the validator set grows. |
| Chains | Many EVM L2s | Ethereum + L2s |
| Feeds | dAPIs | 160+ |
| Security | First-party provenance (data signed at source) + API3 DAO governance. | Transparent validator set with cryptographic (Schnorr) aggregation; every update is independently verifiable. |
| TVS* | Specialized | ~$7.5B |
| Token | API3 | — |
| Best at | First-party data + OEV recapture — turns oracle-update MEV leakage into protocol revenue | Lowest gas cost in the market (≈63% cheaper than Chainlink on Ethereum), with a strong RWA / institutional focus |
* Approximate total value secured — dated market snapshot (DefiLlama / provider reports, 2026).
Pick API3 when first-party data + oev recapture matters most; pick Chronicle when lowest gas cost in the market (≈63% cheaper than chainlink on ethereum), with a strong rwa / institutional focus matters more.
