Curve May No Longer Need to Rely on External Oracles

DeFi

Decentralized liquidity protocol Curve is lowering its reliance on third-party protocols.

Utilizing its lending-liquidating automated market maker algorithm (LLAMMA) — an algorithm that mixes each a conventional lending pool with an automatic market maker (AMM), Curve has made it potential for collateral to be steadily liquidated over a value vary — fairly than merely at one value.

LLAMMA at present depends on an exterior oracle by Chainlink to function its lending swimming pools. When the collateral value is greater, the entire consumer’s deposits will stay secured throughout the deposited collateral. Nevertheless, when the collateral worth drops beneath a sure threshold, the consumer’s deposits will probably be topic to liquidation.

“Just about the whole lot depends on Chainlink, however just lately Curve governance handed a proposal to mainly allow new varieties of swimming pools which have their very own inside oracal,” Blockworks Analysis Senior Analyst Dan Smith defined.

Because of this these liquidity swimming pools can preserve observe of an exponential shifting common of the traded value, taking a mean based mostly on buying and selling dimension and time, much like what an oracle does.

Not like Chainlink, which aggregates the costs of an asset from a number of totally different sources, Curve can be a value based mostly on a single liquidity supply, making it inherently extra dangerous.

It is crucial, due to this fact, that there’s deep liquidity in these swimming pools to make sure that the pool will not be topic to cost manipulation.

“If in case you have a deep sufficient pool, such because the stETH pool with billions of {dollars} in staked ETH liquidity, the worth will probably be troublesome to control. Even when somebody got here in and began dumping into it, they’ll’t simply transfer billions of {dollars} of liquidity round,” Smith mentioned.

The neighborhood is at present figuring out whether or not or not these strong value oracles ought to be carried out in choose swimming pools with deep liquidity.

“That is what DeFi was meant to be, getting away from the reliance on one thing aside from your individual protocol,” Smith mentioned.
