This article explains how it is possible to build hybrid smart contracts using Rootstock, Chainlink oracles, and Hardhat, taking advantage of Ethereum's smart contract capabilities while maintaining Bitcoin's rock-solid security and full EVM compatibility.
Node.js and nvm version manager for node.js need to be installed on your system, and a basic grasp of smart contracts with Solidity and JavaScript/TypeScript is required. Having a Metamask wallet configured for the Rootstock network is also necessary with some test RBTC funds.
The Rootstock Hardhat Starter Kit is used as a foundation for the project, which provides a solid basis for developers.
The Hardhat plugin is added to the configuration setup to use both Rootstock and Chainlink. A .env file is created to store sensitive information, and the necessary dependencies are installed.
A smart contract is created to get real-world asset prices from Chainlink's Price Feeds on Rootstock, facilitating the creation of DeFi applications that require reliable price data.
The deployment script is created to deploy the hybrid smart contract to the Rootstock RSK Testnet, opening up a world of possibilities that combines the security of Bitcoin's network with the flexibility of EVM compatibility and reliable external data through Chainlink oracles.
The article quotes Edward Snowden's Keynote during Bitcoin 2024 to emphasize the importance of consolidating efforts to integrate and create a stronger eco-system with existing tools and protocols.
Finally, the author shares their excitement about the possibilities of Chainlink's Cross-Chain Interoperability Protocol (CCIP), the Verifiable Random Function (VRF), automation for contract maintenance, building more complex DeFi applications using price feeds, among others.
In conclusion, the article invites readers to share their experiences combining these technologies and continue pushing the boundaries of what's possible in the world of hybrid smart contracts.
