NEAR <> Chainlink Oracle Demo

A simple front-end dApp demonstrating how smart contracts on NEAR can access off-chain data using Chainlink Oracles.

• This example allows users to search for and retrieve a token's current market price in USD.

On initial page load, the application auto-connects to the NEAR blockchain using built in access keys configured by the dApp developer. When a search is performed, the application interacts with a client smart contract (already deployed on NEAR) by placing a contract call that invokes the get_token_price method within client. This triggers the following chain of events:

1. Client Contract makes a call to the on-chain Oracle Contract
2. on-chain Oracle Contract makes a request to off-chain Oracle-Node (Chainlink)
3. Chainlink Oracle-Node makes a request to an API
4. API responds with the token price to the Chainlink Oracle-Node
5. Chainlink Oracle-Node passes API response to the on-Chain Oracle contract
6. on-chain Oracle Contract fulfills the original Client Contract request with the API result.

Both the client and on-chain oracle contracts were created & deployed on the NEAR network using a walk-through from this repository which can also provide a deeper look into the inner workings of the above steps.
