ChainSecurity, operational since 2017, is renowned for conducting smart contract audits, especially for high-profile DeFi protocols and Web3 projects. Their approach involves extensive quality assurance and in-depth investigations to uncover novel vulnerabilities, making them specialists in auditing complex and high-stakes smart contracts. Their client base includes notable names in the crypto space, underscoring their expertise and trustworthiness in ensuring blockchain security.


Compound is a decentralized autonomous interest rate protocol. It allows people to lend and borrow their cryptocurrencies, and establishes money markets by algorithmically setting interest rates based on supply and demand of various assets. Its native token is COMP, allowing holders to propose and vote on changes made to the protocol.

Curve is a decentralized exchange protocol. It is mainly utilized for swapping various stablecoins, as its Automated Market Maker mechanism is designed to handle such trades very efficiently. The protocol's native token is CRV, which people may stake for periods of time in order to earn the right to partake in the protocol's governance decisions as well as to claim a part of the protocol's cash flows.

### What

Lido is an open source tool and family of protocols that enables users to mint liquid staking tokens (sTokens) - These liquid staking tokens receive rewards from validation activities of writing data to the blockchain, but unlike their staked counterparts, are "unlocked" which means they can be used in other on-chain activities, like DeFi. 

Lido protocols let users stake native tokens (ETH, MATIC, SOL) from Ethereum, Polygon, and Solana networks in a fully permissionless way. And as the protocols are deployed on public blockchains, users do not need the website to access the smart contracts.

### Why

Traditional staking means that users need to lock-up their ETH or other native asset to be able to secure the network and receive the respective rewards. However, this means that these tokens can't be used for anything else while they are staked. Lido aims to solve this problem. 

Lido protocols give users liquidity - users are able to receive staking rewards from validation activities, but can sell their stTokens (tokens minted on Lido) anytime they want to exit their staking position. 

In addition, it allows users to participate in DeFi while getting rewards - Because sTokens are unstaked and thus "liquid", users can use stTokens as building blocks in DeFi protocols at the same time as getting staking rewards from validating activities.

The Lido DAO also works with experienced node operators, which decreases the likelihood of technical mistakes that could lead to slashing or penalties and minimizes the technical burden for users to receive staking rewards. Users supply the stake, and the node operators supply the know-how.
