Circle

Circle is a global financial technology company that issues the stablecoins USDC and EUROC, and develops programmable wallets across various blockchains. Circle is regulated as a licensed money transmitter under US state law just like PayPal, Stripe, and Apple Pay. Circle’s financial statements are audited annually. ### Why? USDC is a digital dollar, that’s available 24/7 and moves at internet speed. USDC lives natively on the internet, and is available for users to spend regardless of borders and banking hours. Anyone with an internet connection can send, receive, and save USDC. A key feature of USDC is that it's always redeemable 1:1 for US dollars. USDC reserves are held in the management and custody of US financial institutions, including BlackRock and BNY Mellon.

Lido

### 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.
