How the Smart Contract Works?
- The smart contract sends a request to the Chainlink oracle, including the URL and query string.
- The Chainlink oracle retrieves the response data from the external API or data source.
- The Chainlink oracle sends the response data back to the smart contract.
- The smart contract returns the response data to the calling application.
Make HTTP Request Using Your Solidity Smart Contract
Smart contracts are self-executing digital programs that are designed to automate the enforcement of the terms of a contract. Solidity is a programming language used to write these smart contracts on the Ethereum blockchain.
One of the challenges with smart contracts is their inability to interact with the outside world, including making HTTP requests. Smart contracts are often limited in their ability to interact with external systems, which is a major limitation when building decentralized applications. The inability to make HTTP requests is a significant challenge for smart contract developers, as it limits their ability to access external data and services that are necessary to create more advanced and complex decentralized applications.
