# What is stETH?
Lido Staked Ether (stETH) is a liquid staking token representing a staked version of Ether in the Ethereum 2.0 network. Developed by Lido, it is a decentralized staking service. Users get back stETH for their ETH, which is used inside the DeFi ecosystem, while at the same time earning rewards from the staked ETH.

## What Problem Does STETH Solve?
STETH resolves the illiquidity problem faced by staking ETH in Ethereum 2.0. In traditional staking, ETH is locked down for quite a long time, rendering it unable to be used elsewhere. Making staked ETH liquid means an STETH holder can use their assets within the DeFi protocol ecosystem while still earning staking rewards.

### Why Does Crypto Market Need STETH?
The crypto market greatly benefits from STETH, which brings flexibility and utility to staked ETH. By letting stalkers stay liquid, STETH promotes better use of capital and results in an increased level of participation in Ethereum 2.0 staking—in the best interest of network security and decentralization.

##### History of STETH
STETH was introduced by Lido in December 2020, right after the launch of Ethereum 2.0's Beacon Chain. Lido rapidly caught up as one of the best solutions for staking, offering the advantage of a liquid currency against staked assets.

##### Who Developed stETH?
stETH was developed by Lido, a decentralized autonomous organization (DAO). The project had grown its roots from a group of blockchain enthusiasts and developers, which included Vasiliy Shapovalov, Konstantin Lomashuk, and Jordan Fish (Cobie). Lido leverages a governance model in which the community can perform proposals and voting on changes and improvements to the protocol.

### What Technology Does STETH Use and How Does It Work?
STETH technology underlies smart contracts that are used for collateralizing from staking ETH. When one deposits ETH to the Lido staking pool, one gets the corresponding amount in STETH. Lido's validators manage the staked ETH, and smart contracts ensure that over time, the staking rewards will be accrued proportional to the STETH balance.

#### Does STETH Always Maintain a 1:1 Price with ETH?
STETH is designed to be close to the value of ETH, but pegging it at 1:1 is unnecessary. The value of STETH can change marginally due to demand in the market and its accumulation of staking rewards. Normally, STETH trades at a price level similar to ETH's, considering the underlying staked ETH and associated rewards.

###### How Many Tokens of STETH Are There?
The issuance of STETH is dynamic, and it increases as more hold staking gets placed on ETH through Lido. According to the latest information on how many of the digital assets have been staked in total, millions have arisen in the number of STETH tokens now circulating.

###### What is the Maximum Supply of STETH?
There is no hardcoded maximum supply for STETH. The supply will be dynamic and keep increasing with more users staking their ETH through Lido.

#### What is the Utility of stETH?
stETH can be used in the following ways within the Ethereum ecosystem: helping users earn staking yields without compromising liquidity, lending and borrowing in DeFi protocols, and as collateral while using other financial instruments.

### Tokenomics of STETH
The value of STETH is obtained from the staked ETH and rewards accruing to it. The tokenomics are simple: the user gets a staking reward proportional to the number of STETHs they are holding. These rewards continuously add to the total supply of STETH, representing increased value.

### What is the All-Time High and All-Time Low for STETH?
The all-time high for STETH was $4,829.57 on November 10, 2021, with an all-time low of $482.90 recorded on December 22, 2020.

###### Where to Buy STETH?
You can buy STETH on various decentralized exchanges (DEXs), including Uniswap and Curve, and on centralized exchanges (CEXs) that support STETH trading. Users can also get STETH directly by staking ETH using the Lido platform.

#### Who were the early-stage backers of STETH?
Some of the biggest names in crypto investments, including Paradigm, Andreessen Horowitz (a16z), and Three Arrows Capital, which realized the potential of liquid staking solutions, supported Lido in its development.

## How does Lido (stETH issuer) make money?
Lido Finance earns through several streams of income involved in its validation services. Here's how Lido, for the most part, makes money:
**Staking Fees:** Lido stakes users' ETH and claims a portion of that yield to fund the service. In its implementation, there is the usual compromise between accrued fees and the rewards. For instance, Lido takes 10% on staking rewards, while 90% is distributed among holders of STETH. These collected fees are invested in operational purposes as well as in remuneration for the validators and node operators responsible for ensuring the network is secure.
**Lido Infrastructure Validator Rewards:** Lido's infrastructure validators receive rewards for securing the Ethereum 2.0 network. A portion of these rewards return to Lido, hence its overall revenue.
**Governance Token (LDO) Incentives:** Lido awards its native governance token, LDO, to anyone participating within its ecosystem. Those are the LDO tokens, which enable holders to vote on protocol decisions—coming in as one of the earnings with the liquidity mining programs and staking yields. The mechanism through which Lido gains revenue is by holding LDO: the latter will appreciate?
**Partnerships and Integrations:** Lido continues collaborating with several DeFi protocols and platforms by integrating stETH as a usable asset. These partnerships bear further revenue drivers using mutual incentives and shared liquidity provision.
**Ecosystem Growth:** As Lido scales and draws more of the general user base into the platform, the overall value at stake increases, driving up fees collected in total. With the growth of DeFi systems, there will be more sources of revenue through new integrations and services supported by STETH—that is, its liquid staking solution.

### Final Thoughts on stETH
stETH is one of the key innovations within the Ethereum ecosystem, a crucial piece in providing liquidity to staked ETH and, hence, increasing usability for the underlying asset in the context of DeFi. With its robust technology and support base and rising adoption, STETH is set to be a linchpin project in the future of Ethereum staking.
As Ethereum continues down the path of becoming a genuinely proof-of-stake network, the demand for flexible staking solutions, like stETH, is likely to skyrocket. This will drive innovation in the space and solidify Ethereum's position as the preeminent blockchain platform for decentralized applications and finance.
Put in practice, the possibility for stakeholders to stay liquid when staking ETH has various implications and benefits for investors and users. For instance, a DeFi lover may be validating their ETH to secure the network and earn staking returns while also holding stETH as collateral for a loan on a farm. This flexibility is a vital part of the rapidly changing financial landscape, in which maximizing utility—be it from yield farming or something else—can lead to far greater returns, along with risk-management characteristics.
Besides, Lido's decentralized governance model guarantees that stETH will evolve in line with community interests and technological advancements. Such a participatory stance builds trust not only for the users but also invites continuous improvements in response to market needs. With more stakeholders getting into the ecosystem and contributing their part to its maturation, the robustness and versatility of stETH are bound to grow.
