What is Liquid Staking (LST / LRT)?

Definitive Definition

Liquid Staking is a protocol mechanism that enables Proof-of-Stake cryptocurrency holders to stake their assets to secure the network while receiving a transferable, yield-bearing receipt token (e.g., stETH, mSOL) that can be utilized simultaneously across DeFi applications.

In-Depth Architectural & Economic Analysis

Traditional staking locks up assets during unbonding periods (e.g., several days or weeks on Ethereum and Solana). Liquid Staking protocols (like Lido) issue synthetic derivative tokens that accrue validator rewards while remaining fully liquid for trading, lending, or collateralization.

Core Characteristics & Mechanism

  • Unlocks capital efficiency by tokenizing staked validator positions.
  • Supports rebasing tokens (balance increases) or value-accumulating tokens (exchange rate appreciates).
  • Paved the way for Restaking protocols like EigenLayer that extend validator security to third-party services.
Practical Application Scenario:

A user deposits 10 ETH into Lido, receives 10 stETH earning ~3.5% staking APY, and uses that 10 stETH as collateral on Aave to borrow stablecoins.
