Oracle providers

Who this is for: developers who need price or other off-chain data on-chain, and want to know which oracle networks work with Lumia before picking one.

Integration steps and supported feeds are on the linked build guide for each provider.

API3

First-party oracle network: data delivered directly by the data provider.

Supra

Oracle network providing price and other data feeds.

API3

API3 is a first-party oracle network: data is delivered directly by the data provider itself rather than passed through a separate third-party node-operator layer.

Setup: /build/oracles/api3.

Supra

Supra is an oracle network providing price and other data feeds.

Setup: /build/oracles/supra.

Why attestation is covered separately

Asset-backing attestation (proof of reserve, custody attestation) is treated as a distinct trust question from price oracles on Lumia: /lumia/chain-security/oracles-and-attestation.
