Liquid staking derivatives (LSDs) are financial instruments that allow stakers to unlock the liquidity of their staked assets while still earning staking rewards. With traditional staking, cryptocurrency holders have to lock up their assets in order to earn staking rewards, which means they cannot access or use those assets while they are staked. LSDs provide a solution to this liquidity problem.

How LSDs Work

LSDs separate the staking rewards from the staked assets. They allow stakers to earn staking rewards while also freeing up their original staked assets to use as they wish. Here's how it works:

1. A user stakes crypto assets on a platform that issues LSDs, such as a decentralized finance (DeFi) protocol. For example, they could stake Ether (ETH) on Lido, a liquid staking platform.
2. The platform takes the staked assets and stakes them on the blockchain to earn staking rewards.
3. The platform then issues LSD tokens to the user that represent their staked assets plus the future staking rewards. Each LSD token is backed by the staked assets on the platform.
4. The user now holds LSD tokens that earn staking rewards. Meanwhile, they have regained liquidity of their original staked assets, even though those assets are still locked up earning rewards on the platform.
5. The user can sell their LSD tokens on a secondary market to other investors, use them as collateral for loans, or provide liquidity with them on DeFi platforms. All while continuing to earn staking rewards that accumulate within the LSD tokens.
6. When the user wants to unlock their original staked assets, they return the LSD tokens to the issuing platform to redeem the staked assets plus accrued rewards.

So in summary, LSDs allow staking while unlocking liquidity at the same time. The staked assets provide the backing and rewards generation while the LSD tokens provide liquidity and earning opportunities.

Benefits of LSDs

There are several key benefits that LSDs provide:

• Unlocked liquidity - Users can free up their staked assets to use elsewhere while still earning staking rewards. This provides much greater capital efficiency.
• Access to DeFi - By wrapping staked assets in a liquid token, users can utilize DeFi protocols to earn additional yield through lending, liquidity pools, collateralized borrowing, and more.
• Lower minimums - Some proof-of-stake blockchains like Ethereum have high minimum staking amounts. LSDs allow users to participate with smaller amounts.
• Censorship resistance - LSD platforms are decentralized, meaning staked assets are less susceptible to centralized intervention.
• Increased staking participation - The liquidity unlock may encourage more network staking, thus improving decentralization and security.
• Easier stacking management - LSD platforms handle the staking so users don't have to manage validators and other complexities.

Overall, LSDs make staking more efficient, accessible, and decentralized for users while expanding the capabilities of staked assets.

LSD Platforms

A number of platforms have emerged offering LSD products for major proof-of-stake networks:

• Lido - A popular liquid staking platform for Ethereum and other networks like Solana and Terra. Lido's stETH token is a widely used LSD.
• StakeHound - Issues ETH2x-FLI tokens as LSDs for Ethereum staking. Listed on major exchanges.
• Stafi - Provides LSD solutions for a variety of PoS networks, including their rETH token for Ethereum.
• Ankr - Liquid staking protocol offering tokens like aETH for Ethereum and bATOM for Cosmos.
• Alluvial - Specializing in LSDs for Ethereum, Kusama, Polkadot, Solana, and more. Offer staked liquidity on Uniswap.
• Certus One - Supports LSDs for Cosmos IBC-connected chains.
• Figment - Provides LSD infrastructure and products for Solana, Celo, and over 15 PoS networks.
• Chorus One - Liquid staking solution for Cosmos (ATOM) blockchains using their LATOM token.

These platforms all aim to make staking more efficient while maintaining decentralization and enabling broader usage of staked assets. Most act as staking facilitators, operating validator nodes on users' behalf to earn staking rewards.

LSD Risks and Drawbacks

While LSDs solve the liquidity problems of staking, there are some risks and criticisms to consider:

• Centralized platforms - Most LSD platforms are centralized entities, meaning users must trust them to manage staking rewards. This somewhat defeats the ethos of decentralized staking.
• Loss of keys - Issuing platforms control staked assets. Loss of private keys by a platform could jeopardize user rewards. Proper audits and procedures reduce this risk.
• Platform failure - An LSD platform going offline would mean loss of access to staked assets. Users must choose reliable providers.
• Staking dilution - High LSD usage could lead to increased staking participation beyond optimal levels, diluting rewards for other validators.
• Regulatory uncertainty - The legal status of LSD platforms and tokens remains unclear in many jurisdictions. Proper compliance is encouraged.
• Market risk - LSD tokens may trade at discounts or premiums to the underlying staked asset value depending on supply/demand.

While not perfect, LSD platforms provide more benefits than drawbacks for most users. Selecting established, security-focused platforms helps mitigate the risks.

How LSDs Unlock Liquidity

LSD platforms unlock staking liquidity using a few key mechanisms:

Overcollateralized minting
When users stake assets to an LSD platform, the platform mints tokens worth slightly less than the value of staked assets. This ensures the platform is always overcollateralized. The collateral backing plus accrued rewards gives the tokens intrinsic value.
Secondary market trading
After minting LSD tokens, users can trade them on secondary decentralized exchanges like Uniswap. This provides instant liquidity for other uses. Active trading markets keep tokens priced near the underlying staked asset value.
DeFi composability
Interoperability with Ethereum DeFi allows LSD tokens to be used in other DeFi protocols for lending, liquidity pools, collateralized borrowing, and more. This expands their functionality.
Redeemability
Users can redeem LSD tokens directly with the issuing platform in exchange for their original staked assets plus all accrued rewards. This underpins the token value.

Reward passthrough

Platforms distribute a share of staking rewards earned to LSD token holders. This maintains parity between tokens and staked asset rewards.

By utilizing these mechanics, LSD platforms unlock staking liquidity and create tokenized representations of staked assets that retain earning potential.

Case Study: Lido and Liquid Ethereum Staking

Lido is currently the largest liquid staking solution, with over $5 billion worth of Ether (ETH) staked through their platform. Lido handles Ethereum staking on users' behalf, allowing them to earn staking rewards while regaining control of their original ETH.

Here is how Lido unlocks Ethereum staking liquidity:

• Users stake their ETH to Lido by depositing to the Lido smart contract.
• Lido takes custody of ETH and stakes it across multiple validator nodes they operate.
• In return for each staked ETH, Lido mints and credits the user 0.95 stETH tokens.
• stETH tokens represent the user's stake plus earning staking rewards.
• Users can sell stETH, use it in DeFi, or hold it while earning more rewards.
• Whenever desired, users can burn stETH to redeem staked ETH plus accrued rewards from Lido.

stETH tokens maintain parity with ETH by accruing staking rewards. They can be redeemed 1:1 for the underlying staked ETH plus rewards at any time.

Lido provides an efficient way for Ethereum users to earn staking rewards while unlocking their ETH to sell or utilize in DeFi protocols. The stETH token has proven to be a widely popular LSD product with growing adoption.

Evolution of LSD Products

LSD platforms are innovating with more advanced product offerings beyond basic derivative tokens:

• Staked liquidity pools - Projects like Staked allow users to stake and earn rewards on pooled liquidity provision assets.
• Wrapped staked assets - Platforms like Ankr provide wrapped versions of staked tokens like aETH that are pegged through overcollateralization.
• Staked structured products - LSDs are being incorporated into structured products like ETH2x-FLI for leveraged exposure to staking returns.
• Cross-chain LSDs - New solutions allow staked asset derivatives to be moved across chains, such as from Ethereum to Cosmos or Binance Chain.
• Staked portfolio baskets - Investors can deposit various assets to earn rewards across a basket of staked cryptocurrencies in a single LSD token.
• Staked derivatives - Combining staked assets with options, futures, and other financial instruments for tailored exposures.

These more advanced LSD offerings provide users with specialized ways to earn staking yields while maintaining liquidity. The market is still nascent and expanding quickly.

Liquid staking derivatives solve one of the central tradeoffs of proof-of-stake - sacrificing liquidity for staking rewards. By separating the earning potential from the staked asset, LSDs offer the best of both worlds. Users can stake tokens to secure networks while also using their value in other productive ways.

While still a young market, LSD platforms are quickly gaining traction by tapping into immense staked value that was previously locked away. Proper risk management and governance practices will be vital for the industry moving forward. But overall, liquid staking helps expand the possibilities of DeFi and staking for investors. Unlocking staked liquidity creates new opportunities to maximize capital in the decentralized finance economy.
