What is a Liquid Staking Token (LST)? How It Works, Types & Cost

·

In the evolving world of blockchain and decentralized finance (DeFi), Liquid Staking Tokens (LSTs) have emerged as a powerful innovation that bridges the gap between earning passive income and maintaining asset flexibility. Unlike traditional staking, where your crypto is locked and unusable for extended periods, LSTs allow you to maintain liquidity while still earning staking rewards.

This article explores the mechanics, benefits, types, and costs associated with liquid staking tokens—offering a comprehensive guide for both beginners and experienced investors.


Understanding Liquid Staking Tokens

A Liquid Staking Token (LST) is a digital asset that represents staked cryptocurrency on a proof-of-stake (PoS) blockchain like Ethereum or Solana. In standard staking, users lock up their tokens to support network security and earn rewards. However, these staked assets are typically illiquid—they can’t be sold, transferred, or used elsewhere until they’re unstaked, which may take days or even weeks.

Liquid staking solves this limitation by issuing a tokenized version of your staked assets. For example, when you stake ETH through Lido, you receive stETH, which mirrors your staked ETH balance and continues to accrue rewards. You can then trade, transfer, or use stETH in DeFi protocols—all while your original ETH remains staked.

This dual benefit—yield generation plus liquidity—has made LSTs one of the fastest-growing segments in crypto finance.


How Do Liquid Staking Tokens Work?

At its core, liquid staking relies on smart contracts to automate the staking process and issue redeemable tokens. Here's a step-by-step breakdown:

  1. Deposit & Stake: You deposit your cryptocurrency (e.g., ETH) into a liquid staking protocol.
  2. Token Issuance: The protocol stakes your tokens with validators and mints an equivalent amount of LSTs (like rETH or cbETH).
  3. Reward Accrual: As the underlying staked assets earn rewards, the value of your LST increases—either through supply growth (rebasing) or price appreciation.
  4. Redemption: Eventually, you can burn your LSTs to withdraw your original stake plus accumulated rewards.

This system enables continuous participation in DeFi ecosystems without sacrificing yield opportunities.

Why Staking Can Be Illiquid

On Ethereum, staking requires locking at least 32 ETH per validator node—a significant capital commitment. Even smaller stakes are locked during the staking period, meaning users lose access to their funds during market volatility or urgent financial needs. Liquid staking removes this friction, turning static assets into dynamic financial instruments.


Why Are Liquid Staking Tokens So Popular?

The appeal of LSTs lies in their ability to combine passive income with financial flexibility. Here’s why they’ve gained widespread adoption:

This composability makes LSTs a cornerstone of modern DeFi strategies.


Types of Liquid Staking Tokens

There are two primary models for how LSTs accumulate staking rewards: rebasing tokens and reward-bearing tokens. A third, less common model is the dual token system.

1. Rebasing Tokens

Rebasing tokens adjust their total supply over time to reflect earned rewards. For example, if you hold 10 stETH today, you might own 10.2 stETH tomorrow after rewards are distributed. This "elastic" supply means your token balance grows automatically.

2. Reward-Bearing Tokens

These tokens maintain a fixed supply but increase in value per token. Instead of more tokens, you get higher value per token over time.

3. Dual Token Model

Some protocols separate principal and reward components into two distinct tokens.

Wrapped Tokens: Enhancing Compatibility

Many LSTs are wrapped (e.g., wstETH) to improve interoperability across blockchains and DeFi platforms. Wrapping locks the original token in a smart contract and issues a new version compatible with various ecosystems—allowing you to use wstETH across Ethereum, Arbitrum, Optimism, and others.


Real-World Use Cases of Liquid Staking Tokens

LSTs are not just theoretical—they’re actively used across major blockchains and protocols.

Ethereum Dominates the Space

Ethereum remains the most popular chain for liquid staking due to its large DeFi ecosystem and high staking minimums. Leading protocols include:

Solana Gains Momentum

Solana’s rapid growth has fueled demand for liquid staking solutions:

These tokens allow SOL holders to earn yield while participating in DeFi activities like liquidity provision.

Integration with Major DeFi Platforms

Top DeFi applications widely accept LSTs:


What Does Liquid Staking Cost?

While liquid staking offers convenience and flexibility, it comes at a price: service fees.

Most protocols charge a percentage of your staking rewards—typically between 5% and 25%—to cover operational costs and validator incentives.

ProtocolFee
Lido~10%
Rocket Pool~14%
Coinbase25%

For example, if your share of staking rewards is worth $100 in ETH and the fee is 10%, you receive $90. The remaining $10 goes to validators and protocol development.

Despite these fees, many users find the trade-off worthwhile given the added liquidity and utility.


Frequently Asked Questions (FAQ)

Q: Are liquid staking tokens safe?

A: While reputable protocols like Lido and Rocket Pool have strong security records, smart contract risks and market volatility exist. Always audit risks before investing.

Q: Can I lose money with LSTs?

A: Yes. If the underlying asset drops in value faster than rewards accumulate, you may face losses. Additionally, some LSTs trade at a discount to their peg during market stress.

Q: Are staking rewards taxable?

A: In many jurisdictions—including the U.S.—staking rewards are considered taxable income when received. Reward-bearing tokens may defer taxes until sale.

Q: Can I unstake anytime?

A: With traditional staking, unstaking can take time due to network requirements. However, since LSTs are tradable 24/7, you can effectively "exit" by selling them instantly.

Q: Do all blockchains support liquid staking?

A: No. It’s most common on PoS chains like Ethereum and Solana. Not all networks have mature liquid staking infrastructure yet.

Q: Is liquid staking better than regular staking?

A: It depends on your goals. If you want flexibility and DeFi integration, yes. If you prefer full control and lower fees, self-staking may be better.


Final Thoughts

Liquid Staking Tokens represent a transformative shift in how we think about earning yield in crypto. By decoupling the act of staking from asset immobility, they empower users to earn passive income while retaining full control over their capital’s utility.

Whether you're looking to diversify your portfolio, hedge against volatility, or maximize returns through DeFi strategies, LSTs offer a flexible and efficient solution.

As adoption grows across Ethereum, Solana, and beyond, integrating liquid staking into your investment strategy could be a smart move toward optimizing both yield and liquidity.
