Building and Deploying a DeFi Staking Platform with Solidity, Foundry and Next.js

This audio is presented by Hacker Noon, where anyone can learn anything about any technology. Building and deploying a DeFi staking platform with Solidity, Foundry and Next. JS by Pranshu Mishra. Building and deploying a DeFi staking platform with Solidity, Foundry and Next. js as part of week 4 of my ether authority web 3 internship i completed a full stack defy staking platform that allows users to stake erc20stk tokens and earn rwd reward tokens based on the time their tokens remain staked The project combines Solidity smart contracts, Foundry-based testing and deployment, OpenZeppelin contracts, Annexed JS frontend, TypeScript, Ethers, JSand Metamask wallet integration. The final smart contracts are deployed on the Ethereum's Sepolia testnet, and the frontend is deployed using Vercel. Project Objective The objective of this project was to build a working staking dApp from the smart contract layer to the user interface. The platform implements an ERC-20 staking token called STK, an ERC-20 reward token called RWD, a staking contract that holds users staked STK, time-based reward calculation, STK approval before staking, staking, withdrawal of staked tokens, reward claiming, configurable APR for the contract owner. Pause and unpause functionality. Metamask wallet connection. On-chain balance and staking information. Transaction hash links to Sepolia Etherscan. The repository describes the project as a full-stack DeFi staking platform built with Solidity, Foundry, OpenZeppelin, Next. js typescript ethers js and metamask technology stack blockchain and smart contracts solidity open zeppelin contracts ethereum sepulia testnet erc20 token standard foundry forge frontend next js react typescript ethers js metamask Deployment Foundry Deployment Scripts. Ethereum Sepolia. Vercel for front-end hosting. The front-end dependency configuration confirms next. JS, React, React DOM and others. JS as the main runtime dependencies. System Architecture. The platform follows a straightforward Web3 DApp architecture. The front-end creates ethers. js contract instances using the configured stk rw dan staking contract addresses it reads the connected wallets balances and s taking information directly from the blockchain smart contract architecture the project contains three main solidity contracts one two three a foundry deployment script deploys the three contracts in sequence one stake token stk is an open zeppelin erc20 token it uses During deployment, the constructor mints to the deploying address. This contract therefore provides the token users a proven stake in the staking contract. The standard ERC-20 functionality inherited from OpenZeppelin provides operations such as. 2. Reward Token, RWD The reward token is another OpenZeppelin ERC-20 token. The constructor mints to the deploying address. The staking contract later transfers RWD rewards to users when they claim their accumulated rewards. Three, staking contract. The contract is the core of the application. It inherits from and uses OpenZeppelin's. The contract maintains. It also maintains the total public stake and an APR value that starts it. The contract defines custom errors including how staking
