The Aave lending protocol launched a brand new market based mostly on Uniswap liquidity tokens, which lets depositors borrow belongings towards these artificial tokens.
The Uniswap market was launched and introduced on Might 28, and it lets holders of particular liquidity tokens use them as collateral to borrow crypto belongings from the protocol.
Every liquidity token represents possession in a Uniswap liquidity supplier pool, and they are often redeemed for the precise tokens at any level.
Liquidity suppliers obtain a portion of the buying and selling charges acquired by the Uniswap protocol, making it one of many some ways of incomes passive earnings by means of decentralized finance (DeFi).
The liquidity tokens can’t be borrowed, which implies that no extra earnings is acquired when depositing these tokens on the Aave platform.
Stani Kulechov, Aave’s CEO, informed Cointelegraph that this can be enabled afterward, successfully letting customers obtain curiosity from two protocols without delay.
Nonetheless, an attention-grabbing use case of this method is opening leveraged liquidity pool positions. As Aave wrote, this may “significantly scale back decentralized alternate slippage,” because the liquidity swimming pools will be inflated by means of borrowed cash.
To ensure that it to be economically possible, the buying and selling charges would wish to counterbalance the rate of interest on the mortgage and the potential concern of impermanent loss.
On condition that buying and selling charges and rates of interest are variable, this might lead to advanced interactions between the 2 protocols as financial equilibria shift. Nonetheless, the loan-to-value components for these tokens had been set to pretty conservative thresholds of beneath 70%, which places a restrict to the utmost obtainable leverage.
The dangers of DeFi composability
An vital threat addressed by Aave is the right pricing of those liquidity tokens. As these are absolutely artificial tokens whose worth is algorithmically derived by the underlying belongings, failures in Uniswap may threaten the Aave system as properly.
To this finish, the builders created an unbiased contract that might independently derive the worth of the token based mostly on the quantity of underlying belongings throughout the Uniswap contracts. Nonetheless, deviations from the worth of a token on Uniswap and the precise market worth can nonetheless happen in sure circumstances, which Aave assumes to be an assault on the platform.
The system thus makes use of Chainlink oracles to calculate the “true” worth of the liquidity swimming pools, which turns into the first valuation technique throughout these discrepancy intervals.
Nonetheless, these interactions may end up in “coupled threat between the 2 techniques,” as Electrical Capital companion Ken Deeter informed Cointelegraph. Particularly for Uniswap, the scale of its liquidity swimming pools would turn into depending on the Aave protocol.
Deeter famous that with collateralized lending, “volatility magnification” results can already happen on only a single protocol, citing the instance of MakerDAO. Debtors can simply convert their Dai (DAI) into Ether (ETH) and put it again into Maker (MKR), which might enlarge their threat from utilizing the protocol.
However the dangers from these practices nonetheless will depend on the system’s parameters, Deeter concluded:
“I feel the upper stage query is how do these lending techniques steadiness totally different collateral varieties (in order that one going unhealthy does not deliver down the entire system) and what recapitalization schemes have they got, within the case that one thing does go unhealthy.”
Kulechov stated that Aave applies a particular threat framework to stop instability, noting that the interdependencies are “not that totally different from the exposures in conventional finance.”
