Decentralized finance service B.Protocol has introduced plans for a brand new model that can enhance the liquidation of undercollateralized mortgage positions on lending platforms.
In a launch issued on Tuesday, the backstop liquidity protocol for DeFi lending platforms revealed that the upcoming v2 is predicated on a white paper for a novel Backstop automated market maker (B.AMM) written by a few nameless group members.
In response to a weblog put up revealed by B.Protocol founder Yaron Velner the v1 design that utilized skilled liquidators to share earnings with customers as a substitute of miners was not ample to deal with the capital inefficiency drawback.
In contrast to centralized exchanges like Binance that provide leveraged buying and selling as much as 100 occasions consumer deposits, the leverage ratio on decentralized exchanges (DEX) not often exceeds 5 occasions. This considerably decrease leverage restrict is regardless of the huge liquidity pool out there to DEX platforms.
For Velner and the B.AMM white paper authors, the excessive slippage difficulty on DEXes forces lending platforms to be conservative with their mortgage collateral elements. Certainly, with excessive slippage and tight spreads on AMMs like Uniswap and SushiSwap, liquidation on DeFi lending platforms seems restricted to flash mortgage arbitraging.
DeFi lending platforms like Maker make the most of a system of market-maker-keeper (or keepers) accountable for, amongst different features, executing liquidations. These keepers have been the main target of scrutiny throughout black swan occasions like Black Thursday again in March 2020.
Nevertheless, as beforehand reported by Cointelegraph earlier in June, DeFi liquidation mechanisms typically carried out properly amid a “tsunami of liquidations in May.”
B.Protocol’s resolution to the issue is within the type of a platform that enables customers to supply liquidity for doable liquidations — debt reimbursement in return for collateral — by way of an computerized rebalancing protocol that converts collateral for debt reimbursement.
In response to Velner and the B.AMM white paper, the rebalancing course of can be primarily based on the Curve Finance secure swap invariant for asset pricing. Whereas the secure swap invariant is designed for correlated asset pairs like Dai (DAI) and Tether (USDT), B.Protocol v2 will broaden it for uncorrelated pairs like DAI and Ether (ETH).
In a dialog with Cointelegraph, Velner defined how the secure swap invariant can be expanded to work for uncorrelated asset pairs on B.Protocol v2:
“The system is designed specifically for non-correlated assets. This is possible because the system relies on an external price feed (e.g., Chainlink). The Curve Finance’s stable swap invariant is only used to determine the discount in the rebalance process.”

Through the use of an exterior value feed like Chainlink, B.Protocol asset pricing may be generalized in U.S. greenback phrases.
In response to the B.AMM white paper, the proposed excessive leverage DeFi liquidation platform can deal with liquidation of as much as $1 billion per 30 days. The announcement additionally revealed that DeFi lending platforms can improve their collateral elements by as much as 4 occasions on the B .Protocol v2.
Aside from the potential to extend collateral elements for DeFi lending, Velner additionally advised Cointelegraph that the workforce ran simulations on the protocol in the course of the unstable intervals in Might with the outcomes exhibiting substantial yields for customers.
