The Future of Collateral: Liquid Staking Tokens as the New Backing

EigenLayer solves the capital inefficiency of idle LSTs by enabling their restaking to secure new services like oracles and bridges. This creates a flywheel where staked ETH secures both consensus and the broader middleware stack.\n- Capital Efficiency: Unlocks $10B+ in idle LST collateral for additional yield.\n- Security Unbundling: Decouples cryptoeconomic security from validator duties, enabling rapid bootstrapping for new protocols.

The problem with overcollateralized stablecoins is capital lock-up. LSTs provide a solution by offering yield-bearing collateral. This turns a cost center (locked capital) into a revenue-generating asset.\n- Yield-Accruing Collateral: Users earn staking yield while minting stablecoins, reducing the effective borrowing cost.\n- Enhanced Stability: LSTs like stETH and sDAI are more capital-efficient than raw assets, allowing for higher debt ceilings and deeper liquidity.

Native staked assets are siloed. Liquid Staking Tokens, when wrapped (e.g., stETH on Arbitrum, wstETH), solve this by becoming the universal cross-chain money leg. They are the preferred collateral in lending markets like Aave V3 and Compound due to their deep liquidity and native yield.\n- Composability Engine: LSTs become the base asset for perps DEXs and money markets across all major L2s.\n- Liquidity Unification: Creates a single, high-quality collateral standard that bridges Ethereum's security to scaling layers.

Traditional LSTs leak value to block builders via MEV. Next-generation LSTs like Rocket Pool's Reth solve this by integrating a smoothing pool and distributing MEV rewards directly to stakers. This creates a more equitable and higher-yielding staking derivative.\n- Yield Optimization: Captures and redistributes MEV & priority fees, boosting base APR.\n- Fairer Distribution: Mitigates the winner-takes-all dynamic of solo staking, appealing to a broader user base.

LSTs are used as collateral to mint stablecoins and borrow more of the underlying asset, creating a dangerous leverage cycle. A price shock triggers a cascade of liquidations that collapses both the LST and its derivative ecosystem.

• Reflexive Risk: LST depeg can implode protocols like Aave and Maker that hold it as primary collateral.
• Concentration Danger: Lido's stETH dominance (>70% of Ethereum LST market) creates a single point of failure for DeFi.

Underlying validator slashing events are socially pooled across LST holders, but a large-scale slashing event could trigger a bank run as users flee to non-slashable assets, breaking the peg.

• Asymmetric Information: Users cannot assess the slashing risk of the underlying validator set managed by operators like Figment or Coinbase.
• Liquidity Crunch: A loss of confidence would overwhelm DEX liquidity pools (e.g., Curve's stETH/ETH pool), decoupling the peg.

If major LSTs like Rocket Pool's rETH or Frax's frxETH are deemed securities by the SEC, centralized exchanges would delist them, destroying liquidity and composability overnight.

• DeFi Fragmentation: On-chain protocols would be forced to choose between compliance and utility, splitting liquidity.
• Staking Centralization: Regulation could push staking back to regulated custodians, undermining Ethereum's decentralization thesis.

As staking participation approaches saturation (~80%+ of ETH staked), rewards diminish. LSTs lose their yield advantage, making them unattractive as collateral compared to stable yield-bearing assets like Ethena's USDe or Treasury bills.

• Collateral Rotation: Capital flees to higher-yielding, non-correlated assets, draining TVL from LST-based DeFi.
• Protocol Insolvency: Lending markets collateralized by low-yield LSTs become economically unviable.

$100B+ in LSTs is trapped in simple yield loops, failing to unlock its full capital efficiency. The opportunity cost of idle staked capital is a systemic drag on DeFi's composability and leverage potential.

• Capital Inefficiency: LSTs are underutilized as collateral outside of basic lending markets.
• Fragmented Liquidity: Each major chain's native LST (e.g., stETH, cbETH, sAVAX) creates isolated liquidity silos.
• Yield Compression: Simple staking yields are being commoditized, failing to capture the value of the underlying collateral.

Infrastructure that treats LSTs as programmable balance sheets, not just tokens. This enables risk-isolated vaults and cross-chain collateral networks.

• Restaking Protocols: EigenLayer and Babylon abstract staked security into a reusable resource for Actively Validated Services (AVSs).
• LST-backed Stablecoins: Projects like Ethena's USDe use stETH yield to collateralize a delta-neutral synthetic dollar.
• Cross-Chain Collateralization: LayerZero and Chainlink CCIP enable LSTs from Ethereum to secure loans or mint assets on other L2s and L1s.

LST collateral introduces new slashing and depeg risks. The next generation of protocols must have native risk engines, not outsourced oracles.

• Slashing Insurance: Automated mechanisms to socialize or hedge the risk of validator penalties, moving beyond simple over-collateralization.
• LST Volatility Oracles: Real-time monitoring of the discount/premium of LSTs vs. native assets (e.g., stETH/ETH peg).
• Multi-Asset Backstops: Protocols like MakerDAO's Endgame plan to diversify collateral with real-world assets (RWAs) to mitigate systemic LST concentration.

LSTs will become the base money for a multi-chain ecosystem, settling cross-domain debt and enabling trust-minimized leverage. This turns Ethereum into a global collateral hub.

• Cross-Rollup State Verification: Using staked ETH to secure fraud proofs or validity proofs for L2s, as seen with Polygon's zkEVM using Ethereum for data availability.
• Intent-Based Leverage: Systems like UniswapX could use LST collateral to source liquidity across chains without user bridging.
• Composability Explosion: A loan collateralized by stETH on Avalanche could mint a stablecoin used for trading on Arbitrum, all settled on Ethereum L1.
