Chainlink Price Aggregation Example

Example contract that creates 3 separate Chainlink requests and averages the responses.

Requirements

• NPM
• Truffle
• GCC (for testing)

Installation

$ npm install

Test

$ npm test

Deploy

If needed, edit the truffle.js config file to set the desired network to a different port. It assumes any network is running the RPC port on 8545.

Local development

$ npm run deploy:dev

Public chains

Requires unlocked & synced Ethereum node. Accepts --network ropsten and --network rinkeby currently.

$ truffle migrate --network ropsten --compile-all

There is also a flattened contract at the root directory available for importing directly into Remix.
