Liquid Restaking Tokens vs. Liquid Staking Tokens: A Technical Deep Dive

Introduction to Staking and Liquidity

Proof-of-Stake (PoS) blockchains allow users to secure the network by locking tokens for participation, enabling them to earn rewards and create stronger security mechanisms. However, traditional token staking restricts asset movement, thus decreasing access to available funds for further usage. Liquid Staking Tokens (LSTs) and Liquid Restaking Tokens (LRTs) are innovative solutions to this situation. LSTs create tradable digital certificates and tokenize staked assets, making them more liquid and usable. LRTs, on the other hand, allow users to use their staked assets across multiple protocols, further enhancing their utility.

Liquid Staking Tokens (LSTs)

The Proof-of-Stake (PoS) ecosystem becomes more accessible through Liquid Staking Tokens (LSTs), an innovative solution that includes Ethereum's stETH and Solana's mSOL alongside cross-chain platforms such as StakeStone. These tokens transform staked assets into liquid derivatives, maintaining their underlying value and accrued rewards. Liquid Staking Tokens function similarly to the underlying assets' worth alongside accumulated rewards to enable easy usage across decentralized finance (DeFi) platforms for trading, lending, and yield farming activities. Automated smart contracts build LSTs, allowing users to delegate their staked assets to validators without locking their funds or managing validator nodes while still receiving staking rewards through a liquid token format.

Technical Workflow:

1. Deposit & Minting: When users deposit proof-of-stake assets, such as ETH, to a platform like Lido, they receive corresponding stETH tokens in a 1:1 exchange. These stETH tokens represent their staked assets in a liquid form.
2. Validator Delegation: The assets are pooled into validator operations, and risks from slashing are minimized through insurance mechanisms or by using extra collateral.
3. Reward Accrual: The valuable rewards deposited into LST protocols become visible to users through supply adjustments (rebasing) or appreciation of token prices (such as Coinbase's cbETH).
4. DeFi Integration: LSTs serve as collateral (Aave), liquidity (Uniswap), or restaked assets (e.g., StakeStone's cross-chain yield strategies).
5. Redemption: Users burn LSTs to reclaim their assets, either through direct withdrawals that experience chain-based queuing delays or by performing instant swaps enabled by liquidity pools.

Advantages and Innovations
LSTs address critical limitations of traditional staking, offering:

1. Unlocked Liquidity: Stakeholders maintain full access to their assets through which they can deploy LSTs for DeFi strategies like liquidity provision on Curve to earn dual yield rewards.

2. Accessibility: Removing technical requirements (such as node management) and setting no minimum staking amount increases adoption.

3. Yield Amplification: The method merges staking rewards of 4–6% Annual Percentage Yield on Ethereum and returns from Decentralized Finance pools like Aave, which range between 3–8%.

4. Simplified Access: The system removes 32 ETH minimums and eliminates operational complexity for nodes.

Liquid Restaking Tokens (LRTs)

Liquid Restaking Tokens (LRTs) provide users with programmable assets that let them maximize returns through multi-service staked Ethereum restaking while keeping assets liquid. LRTs operationalize Ethereum security through middleware protocols to support Actively Validated Services (AVSs) since they combine staking rewards (3–5% APY) with security compensation from protecting multiple network protocols (such as rollups and oracles). Through technical abstraction, LRTs allow users to stake and participate in Decentralized Finance without jeopardizing their liquidity, opening up exciting possibilities for the future.

Technical Workflow:

1. Deposit & Tokenization: Users deposit staked assets (e.g., ETH) into a liquid restaking protocol. The protocol mints liquid tokens (e.g., LRTs) representing their stake.
2. Delegation: Assets are delegated to node operators/validators for consensus participation (e.g., Ethereum PoS).
3. Liquidity Utilization: Liquid tokens can be traded, used in DeFi (e.g., lending, AMMs), while still earning staking rewards.
4. Reward Distribution: Staking rewards (e.g., block rewards, MEV) are auto-compounded or distributed to users via the liquid tokens.
5. Redemption: Users burn liquid tokens to withdraw their underlying assets (+ rewards), subject to unbonding periods if applicable.
6. Slashing Mitigation: Protocols often implement insurance pools or overcollateralization to offset validator penalties.
7. Continuous Rebalancing: Assets may be dynamically reallocated to optimize returns and reduce risk across validators.

Advantages and Innovations

• Dual Yield Streams: Users can access Ethereum staking rewards at 3-5% while earning additional benefits at 2-8%+ from AVS.
• Ethereum Security Reinforcement: AVSs utilize the validator pool of Ethereum while minimizing the risk of slashing through this approach.
• Risk Diversification: Exposure to varied AVS risk/reward profiles (e.g., bridges vs. oracles).
• Gas Efficiency: The distribution process of batch rewards helps decrease blockchain transaction expenses.

Capital efficiency becomes transformed through LRTs by combining Ethereum's security mechanisms with multichain functionalities. The integration of phased AVS deployments alongside native restaking capabilities enables yield opportunities. However, protocol developers must establish strong measures to defend against liquidity issues, slashing events, and centralization risks.
