Doot L1 Mina Smart Contract

Doot Oracle provides cryptographically verified price feeds on Mina. The active surface area of this repo is the Doot contract and its deployment scripts; the legacy Registry and Aggregation components have been parked under extras/ for reference.

Doot.ts

• Stores a TokenInformationArray with prices[10], lastUpdatedAt (wall-clock ms), and priceSeq (strictly increasing, +1 per update).
• Callers supply lastUpdatedAt; the contract enforces monotonicity and bumps priceSeq on-chain.
• getPrices() returns the full struct so downstream consumers can gate settlement on both freshness and monotonic sequence.
• Off-chain rollups enforce lastUpdatedAt and priceSeq growth; stale updates or proofs are rejected.
• Helper verifyPriceBundleSignature verifies an owner signature over (priceSeq, lastUpdatedAt, prices[]).
• Recommended settlement pattern: require priceSeq > lastSeqUsed and lastUpdatedAt >= marketEndTime before accepting prices.

Archived components

• Registry and Aggregation code, tests, and deploy scripts now live in extras/ and are no longer part of the active build.

There are two parts to the story. One implemented on Mina and other on Ethereum (EVM in general.) The mina part deals with everything Mina Protocol. The ethereum part deals with everything EVM.
