Composable Markets

Since Ion is targeted at supporting validator-backed assets, supply-side liquidity in the lending markets can comprise of any staked or restaked asset. Ion's first markets accept wstETH as the underlying lending asset, providing wstETH holders access to additional passive yield without exposing themselves entirely to the trust assumptions and risks of restaking.

Understanding Market Composability

Market composability refers to Ion's ability to segment lending pools within the protocol, each with their own distinct set of assets, risk parameters, and interest rates. This segmentation ensures that the risks associated with one market do not spill over into others, safeguarding the protocol and its users from systemic failures. By segmenting markets, Ion Protocol can accommodate many assets, including emerging or more volatile tokens, without exposing the entire market to undue risk.

Features of Composable Markets

  • Risk Management: Composable markets allow for precise risk management by adjusting the parameters such as collateralization ratios and interest rates based on asset risk profiles.

  • Enhanced Security: By segmenting collateral asset subgroups, any adverse events affecting one market have minimal impact on others, thereby enhancing the overall security of the protocol.

  • Innovation & Efficiency: Isolated markets provide a testing ground for new assets and strategies, fostering innovation while maintaining platform integrity.

  • Customization: Lenders and borrowers benefit from more tailored financial products, as each market can offer conditions suited to the specific needs and risk appetites of its participants.

How It Works: Lending LSTs

In the context of Ion Protocol, composable markets facilitate transactions where lenders supply LSTs and other ETH-backed assets like wstETH, and borrowers use liquid restaking tokens as collateral to borrow the wstETH. Here's how it works:

  1. Supplying LSTs: Lenders contribute their LST to an isolated market, or a combination of isolated markets. In return, they receive interest payments based on the market's borrow rates, which are determined by the supply and demand dynamics within that isolated market. This is in addition to maintaining their staking yield.

  2. Benefiting from the collateral's yield: In markets that are profitable for borrowers, the borrow rate mo with reacts to the collateral's underlying yield because of Ion Protocol's interest rate model. The interest rate model incorporates a minimum interest rate curve to create a floor, with an uncapped upside. So if the collateral's yield increases, lenders can earn additional revenue.

  3. Collateral Specific Incentives: Lenders will also be eligible to receive any additional incentives provided by the collateral's provider for the markets they supply to.

Isolated markets within Ion Protocol represent a significant advancement in DeFi lending, offering a balanced approach to innovation, security, and risk management. By allowing lenders to supply staked and restaked assets and borrowers to leverage liquid restaking tokens as collateral, Ion Protocol not only broadens access to capital and additional yield for stakers and restakers but also introduces a safer, more adaptable framework for generalized lending and borrowing activities.
