LST-Backed Stablecoins and Their Dynamics in the DeFi Space

LST-Backed Stablecoins and Their Dynamics in the DeFi Space

Kim Impossible

In the realm of DeFi, decentralized stablecoins have become a cornerstone for various financial operations, such as trading, lending, and borrowing. Stablecoins backed by Liquid Staking Tokens (LSTs), sit at the cutting edge of innovation and play a pivotal role by providing borrowers, or holders, of the stablecoin with the lowest available risk in DeFi: the Ethereum staking rate, which is a necessary parallel to the risk-free rate found within traditional financial (TradFi) markets.

Simultaneously, these stablecoins offer a stable medium of exchange, unit of account, and store of value, all while mitigating many risks — such as blacklisting and freezing — presented by centralized stablecoins.

Key Players and Analytical Insights:

1. Lybra Finance | eUSD

Lybra is a notable presence in the DeFi sector as an overcollateralized stablecoin. It is backed by wstETH, rETH, and wbETH, and provides stablecoin holders the opportunity to earn a passive yield, directly sourced from the stablecoin collateral. This unique feature has significantly contributed to its success in bootstrapping TVL.

Impressive TVL Stats: Lybra achieved a 246 million USD TVL with an all-time high (ATH) of 391 million USD. A notable drop occurred due to the rollout of V2, though it is currently on a recovery trajectory.

Revenue Insights: The annualized revenue sits at $1.48m according to

Yield Opportunities: Lybra offers the highest available yield through rebasing at 8% for holders, with composability through various DeFi platforms, such as Convex and Pendle.

Borrowers’ Yield Utilization: The utilization of the borrowers’ yield to reward stablecoin holders aligns incentives in such a way that the stablecoin is consistently sitting above it’s peg (i.e. Hodling demand< CDPs supply).

Interest Rates: The interest rate is fixed at 1.5%.

Minimum Collateral Ratio: Lybra has a minimum collateral ratio (Min CR) of 150%, serving as a hard-ceiling for the peg at 1.5 USD.
