Intro
In 2022, Index Coop launched icETH, a simplified way to tap into leveraged staking yields and it quickly attracted tens of millions of dollars in TVL. Fueled by stETH’s listing on Aave, leveraged looping exploded across DeFi as the go-to strategy to maximize ETH yields.
Today we are excited to unveil the next evolution: wstETH15x.
Introducing Smart Loops
Index Coop Smart Loops are yield tokens built on advanced ‘recursive looping’ strategies. Each Smart Loop taps into established DeFi protocols like Morpho and Aerodrome to help you capture higher yields safer and without the hassle. wstETH15x is the first in the series, providing several key benefits:
Higher Leverage, Real Yield
All yield is created through genuine staking rewards amplified by leverage. No gimmicky token incentives.
At the time of launch, wstETH15x delivered a 7-day APY of 9.84%, outperforming nearly every ETH yield opportunity listed on vaults.fyi.
Where icETH amplified staking returns up to 2.5x, wstETH15x can reliably achieve up to
15x leverage on real ETH staking yields.
No Manual Upkeep and Built-in Protections
Smart Loops automate the entire process and safeguard against sudden depegs by reducing leverage when necessary.
This allows users to sleep easy while reaping the rewards of higher levels of leverage.
Simplified Accounting in a Single Token
All Smart Loops are repricing tokens, meaning they accrue value directly to the token price over time.
Repricing tokens can drastically simplify bookkeeping by allowing users to simply track one token’s value over time rather than a stream of transactions.
Depending on your jurisdiction, this can potentially classify value accrued as capital gains, rather than ongoing “income” from each re-stake. (disclaimer: not tax advice, please consult a certified professional.)
Lower Fees on Base:
Being native to L2, wstETH15x features greatly reduced gas costs compared to Ethereum Mainnet.
The Strategy
All Smart Loops employ a version of the following strategy:
Lending some amount of capital
Borrowing another currency against it
Swapping the borrowed amount for the original asset
Repeating the process (i.e. looping) in order to gain more exposure to the original asset
wstETH15x aims for about 15x leveraged exposure to stETH. Following the logic above, it deposits stETH to Morpho, borrows ETH against it, swaps the borrowed ETH for wstETH, and lends that wstETH as collateral—repeating until it reaches the 15x target. This multiplies the staking yields you’re collecting, but it also magnifies price movements.
With each loop, your incremental exposure to the lent asset gets smaller and the “safe-zone” tightens. That means the strategy becomes more sensitive to any price differences between the lent and borrowed assets.
As the band narrows and the sensitivity to price movements amplifies, managing the position by hand can become tricky.
Smart Loops handle this by targeting a specific leverage range and automatically rebalancing whenever the price moves outside that band. This lets you push leverage further than you’d ever feel comfortable doing manually.

Index Coop yield tokens simplify earning yield in DeFi by automating complex strategies and diversifying across protocols. They are user-friendly and cost-efficient, appealing to both new and seasoned DeFi users.
Leverage tokens automate a leveraged position by utilizing onchain money markets like Aave or Morpho to borrow funds, amplifying a user's exposure to an asset without requiring manual management. The token's smart contracts autonomously handle the borrowing, lending, and rebalancing of assets, maintaining a consistent leverage ratio despite market fluctuations. This automation eliminates the complexities of collateral management and liquidation risks, while also charging low, transparent fees that avoid expensive funding rates often charged by perps.
Index Coop is a decentralized autonomous organization (DAO) that specializes in creating and maintaining onchain structured products. Index Coop aims to democratize access to the crypto market, empowering everyone to participate in the growing digital asset ecosystem with ease.
No, yield automatically compounds and accrues to the token price. The value of the tokens you hold in your wallet will simply go up over time without the need to claim or compound rewards.
Index Coop products protect you from liquidation with automated risk management that rebalances assets to maintain a target leverage ratio that avoids liquidation.
