DeFi Staking Protocol StakeVault Tackles Complex Accounting Challenges

DeFi staking protocols can seem simple at first glance: users deposit tokens and wait for rewards. However, when multiple users interact with a staking pool, accounting becomes increasingly complex.

This is where StakeVault comes in, a finite-reward DeFi staking protocol built on Solidity and Foundry. The project was designed to explore the challenges of correct accounting in staking protocols, including staking, withdrawing, claiming rewards, changing reward rates, and interacting with a finite number of tokens.

StakeVault combines smart contracts, testing using Foundry, and a React frontend deployed on Ethereum Sepolia. It addresses various questions that arise when building a staking protocol, such as how to distribute rewards between users, what happens when the reward pool runs out, and how to represent global protocol state separately from individual wallet state.
