When a user is ready to be liquidated, these bots — run by third-party programmers and traders — jockey to liquidate the positions so they can earn a bonus for doing so, a common practice in DeFi. As many bots compete to liquidate a position, that can clog a blockchain with transactions. Meanwhile, a dump of a slew of coins by liquidators can also further pressure token prices, prompting another cascade of liquidations. By stepping in, DeFi communities are trying to avoid all of this.
“A lot of DeFi protocols are reducing counterparty exposure during this volatile time,” said Paul Veradittakit, a partner at Pantera Capital.
The DeFi apps’ communities are also rallying to make sure their apps don’t get damaged by things like bad debt: If a liquidator can’t sell illiquid tokens, or if the tokens’ prices collapse as they are being sold, the apps can end up being held responsible for reimbursements.
In the case of Solend, holders voted overwhelmingly in favour of a proposal to take over a large user’s account temporarily after the app reached out to the user to no avail, bringing the threat of a massive liquidation closer. Should a rash of bots start competing to trigger the liquidation, the proposal stated, “this could cause chaos, putting a strain on the Solana network.”
By taking over the account, the Solend team could attempt to liquidate the position in such a way that the liquidated tokens’ price is less affected, through an over-the-counter sale with a specific buyer rather than on a DeFi exchange.
But the move is highly unconventional, breaching the norms of DeFi and causing some on Crypto Twitter to bristle. And, a single crypto address accounted for the lion’s share of tokens that voted for the proposal, seemingly undercutting to some the idea of “community” espoused by DeFi.
The move comes a day after MakerDAO, an app that supports stablecoin DAI, suspended the token from being deposited and minted in Aave’s crypto lending platform because of Aave’s exposure to a troubled derivative of Ether called stETH, which has become illiquid. The suspension prevents traders from borrowing DAI against stETH. On Aave’s governance forum itself, users are hotly debating how to reduce the risk from stEth, which DeFi risk tracker Gauntlet says “may pose further risk to the protocol.”
DeFi apps’ pain was triggered after centralised crypto lenders Celsius Network and Babel froze deposits, and the rumoured collapse of fund Three Arrows Capital, which sent crypto prices down in the double digits over the past seven days.
Celsius worked with many DeFi apps to earn high returns. About 30% of all stEth stuck on Aave, for example, is from Celsius, according to researcher Novum Insights. Three Arrows Capital, meanwhile, was an investor in Lido, which issued stETh, and is debating a change in how it’s governed.
As tracked by DeFi Llama, the total value locked in DeFi, the amount of crypto in use on apps, has plunged to $70.6 billion from $205.7 billion on May 5, just before the Terra blockchain’s implosion set off the year’s biggest crypto crisis so far.
