Solana-based stablecoin NIRV drops 85% following $3.5M exploit
Solana-based algorithmic stablecoin NIRV has develop into the newest stablecoin to fail, after dropping 85% from its greenback peg following a hack on adaptive yield protocol Nirvana Finance on Wednesday.
The flash mortgage assault, which additionally noticed Nirvana Finance’s native token ANA drop by 85%, resulted within the lack of $3.49 million price of Tether (USDT), with the SolanaFM group being the primary to verify that the funds have been siphoned by way of a flash mortgage assault on July 27:
“Using Solend Protocol’s Flash Loans, the hacker borrowed $10M USDC from the Solend Important Pool Vault which was used to take advantage of $3.49M USDT from the Nirvana Finance Treasury.”
On the time of writing, each NIRV and ANA are down roughly 85% to $0.14 and $1.33 apiece. On Nirvana’s web site, it confirms that the protocol was “maliciously hacked and reserve funds are stolen. NIRV and ANA have misplaced their collateral, and wouldn’t have secured market worth.”
What we all know thus far:
Nirvana has been maliciously hacked and the reserves have been stolen.
A flashloan assault was used to steal cash. This isn’t the fault of Solend, however an exploit of Nirvana’s program.https://t.co/NkmtHAbAAa

The Nirvana group is now providing the hacker a whitehat bounty of $300,000 and a “cessation” of the investigation into their identification. Up to now they revealed that the hacker’s pockets tied to a centralized trade has been flagged.
“Please settle for this good religion request and return our treasury for the nice of the entire Nirvana group. You haven’t taken cash from VCs or giant funds—the treasury you’ve gotten taken represents the collective hopes of on a regular basis folks,” it wrote.
To The Nirvana Hacker:
On behalf of the Nirvana Finance group, we humbly ask that you just return the stolen funds from our treasury. 1/5

One other algo bites the mud
The algorithmically collateralized NIRV is unironically described by the protocol as a “superstable” token. In response to an explanatory thread on Solana Boards, the asset is backed by a community of stablecoins in Nirvana’s reserves by way of a “decentralized peg delegation.”
“NIRV is at all times handled as $1 from the protocol’s point-of-view. This greenback worth is denominated in ANA tokens. As an illustration, if the spot worth of ANA is $12, the protocol accepts 12 NIRV to buy an ANA token.”
On this occasion, it seems that NIRV was depegged as a direct results of $3.49 million price of USDT being stolen from Nirvana’s coffers. It marks one more algo-stablecoin that has been severely depegged in 2022. Beanstalk Farm’s algorithmic stablecoin is sitting at $0.0022 after the protocol was hacked for $182 million in April.
Terra’s first variation of its algo-stablecoin Terra USD additionally famously imploded following a dying spiral that resulted in $40 billion being wiped from the market in Might.
The way it labored
In response to blockchain audit platform OtterSec, a hacker used a program to artificially pump the worth of ANA from $8 to $24 by way of the flash mortgage. They have been then in a position to mint ANA in opposition to the flash mortgage on the inflated worth, and subsequently exchanged the asset for $3.49 million price of USDT which was drained instantly from Nirvana’s treasury.
OtterSec famous that his hack shared similarities with the assault on Crema Finance price $10 million earlier this month, wherein the attacker took out a flash mortgage from the Solend decentralized finance (DeFi) protocol to inflate pricing information and raid the protocol.
2/ This hack beared many similarities to earlier hacks. Much like the @Crema_Finance hack, this too used Solend flashloans.
The attacker’s program was additionally uploaded on-chain and closed instantly afterwards. https://t.co/kgg7C2M2Gq pic.twitter.com/GJaAZlfJZD

SolanaFM additionally famous that the hacker exited the assault by changing “the complete USDT quantity into USDCet, transferring the funds into an ETH account” by way of Wormhole’s cross-chain bridge.
