Implementation Plan: Tycho Trustless Price Oracle Library

Objective:
Develop a fast, trustless price oracle library for all tokens using Tycho, based on the TAP-3 specification.

Architecture Overview

Data Source:
Leverage Tycho's liquidity indexer to fetch real-time on-chain data from multiple decentralized exchanges (DEXs).

Price Calculation:
Use Time-Weighted Average Price (TWAP) mechanisms to ensure price integrity and protect against short-term manipulation.

Trustless Design:
All data will be sourced directly from on-chain protocols—no off-chain APIs or centralized dependencies.

Technology Stack

Language: Rust (using Tycho’s libraries and tooling)

Data Layer: Tycho Substreams for scalable and efficient data access

Testing: Unit tests and integration tests to verify reliability and accuracy

Deliverables

A modular Rust library providing trustless price feeds for any token pair

Developer-friendly documentation covering setup, usage, and integration

A complete test suite ensuring performance and correctness
