PPI — the commodity price index
A fixed-weight index of 14 commodity exposures, computed on-chain from prices published by a 2-of-3 signed oracle. This page reads Arbitrum One directly. Everything below can be recomputed from public inputs — see the methodology.

Contracts
Oracle
Pull model: prices are signed off-chain for free. A consumer submits them in its own
transaction and pays that gas. Feed: /api/v1/price-signed
What this is not. Not a claim on physical commodities, not a total-return or
futures-roll index, and not audited by a third party. Minting is disabled: there is no
deposit token, so no one can put funds into the protocol. The index exists to be read and,
eventually, licensed.
For venues
Listing or licensing PPI: the methodology is public, the contracts are verified, and the oracle feed is free to read. Start at operators or read the rulebook.
