Curve Might No Longer Have to Depend on Exterior Oracles

Decentralized liquidity protocol Curve is taking a look at 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 attainable for collateral to be progressively liquidated over a worth vary — quite than merely at one worth.

LLAMMA at present depends on an exterior oracle by Chainlink to function its lending swimming pools. When the collateral worth is larger, all the person’s deposits will stay secured inside the deposited collateral. Nevertheless, when the collateral worth drops beneath a sure threshold, the person’s deposits shall be topic to liquidation.

“Just about every thing depends on Chainlink, however not too long ago Curve governance handed a proposal to mainly allow new kinds of swimming pools which have their very own inside oracal,” Blockworks Analysis Senior Analyst Dan Smith defined.

Which means that these liquidity swimming pools can preserve monitor of an exponential shifting common of the traded worth, taking a mean primarily based 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 completely different sources, Curve could be taking a look at a worth primarily based on a single liquidity supply, making it inherently extra dangerous.

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

“You probably have a deep sufficient pool, such because the stETH pool with billions of {dollars} in staked ETH liquidity, the value shall be troublesome to govern. Even when somebody got here in and began dumping into it, they’ll’t simply transfer billions of {dollars} of liquidity round,” Smith stated.

The group is at present figuring out whether or not or not these strong worth oracles needs to be carried out in choose swimming pools with deep liquidity.

“That is what DeFi was supposed to be, getting away from the reliance on one thing apart from your personal protocol,” Smith stated.
