Description
This issue is to port the core Chainlink aggregation contract functions into Agoric:
Implementation must be written in JavaScript following Agoric's smart contract model. The contract must result in a PriceAuthority API that the Agoric Treasury can consume. The Agoric team will review the initial design and will be available for consultation on implementation questions.
Contracts should reflect best practices for the Agoric environment and unnecessary Solidity logic can be discarded (for example, EVM-specific choices such as certain gas optimizations should be ignored).
See below for references to the specific contracts and Agoric documentation for details.
Context
Agoric's treasury vaults require reliable price feeds for collateral. Chainlink price feeds may be used, particularly for collateral assets such as Ethereum which have robust reporting but may be less liquid at first on the Agoric chain.
A full integration with Chainlink requires several steps. Agoric has already completed the external adapter and external initiator which allow Chainlink nodes to talk to the Agoric chain.
The core remaining piece for price feeds is the on-chain contract which accepts data from nodes and aggregates it for delivery to the client (e.g., the Treasury Vault contracts).
