Because the grime settles on the cataclysmic crumple of the Terra ecosystem, an on-chain deep-dive applied by blockchain analytics company Nansen highlights two main takeaways.
The cryptocurrency ecosystem was once awash with varying speculatory theories around the reason of Terra’s algorithmic stablecoin UST’s decoupling from its $1 peg. The who and why looked a thriller however the consequence was once catastrophic, with UST dropping properly below $1 whereas the worth of Terra’s stablecoin token plummeted in price consequently.
Nansen undertook an investigation leveraging on-chain recordsdata from the Terra ecosystem to the Ethereum blockchain with a notion to chart the chain of events that resulted in the UST depeg.
It is miles worth noting that the file does no longer embody capability off-chain events that would also own exacerbated the topic, impression on investors, breakdown of earn losses between wallets, and what came about to Bitcoin (BTC) reserves backing UST.
Attackers preyed on shallow Curve liquidity to milk arbitrage alternatives
The main and finest takeaway was once Nansen’s identification of a minute position of addresses or players that known vulnerabilities within the Terra ecosystem. These actors preyed on the slightly shallow liquidity of Curve pools backing the TerraUSD (UST) peg to other stablecoins and moved to capitalize on arbitrage alternatives.
The file outlines how these actors withdrew UST funds from the Anchor protocol on Terra. These funds had been then bridged from Terra to Ethereum making employ of the Wormhole infrastructure.
Huge quantities of UST had been then swapped with more than just a few stablecoins in Curve’s liquidity pools. Nansen then speculated that within the course of the depegging direction of, a pair of of the known wallets exploited discrepancies between pricing sources on Curve as properly as decentralized and centralized exchanges by taking buying and promoting positions during exchanges.
Nansen’s file refuted a speculative yarn that a single attacker or hacker labored to destabilize UST.
Seven wallets central to UST’s depeg
Nansen’s blockchain prognosis adopted a grounded thought capability that known connected transaction quantity recordsdata between Might 7 and 11—the time body by which UST lost its $1 peg.
The company reviewed social media and dialogue board threads to slim down that exact time body, highlighting a properly-known transaction drift on Curve liquidity pools, which resulted in its three-part analytical capability.
Fragment one eager the prognosis of transactions inside of and outdoors of the Curve lending protocol, which allowed Nansen to bring collectively a checklist of wallets whose activities counsel a critical impression on the UST depegging.
Fragment two was once a minute more complex, as Nansen noticed transactions throughout the Wormhole bridge that would also merely own influenced the depeg tournament. The company reviewed outflows of UST from the Anchor protocol bright a narrowed-down list of wallets. This was once followed by investigating the sale of UST and USDC on centralized exchanges.

The closing part eager triangulating on-chain proof to maintain a yarn of the events around the UST depeg. A list of seven wallets was once then highlighted that are believed to had been central within the Terra ecosystem crumple.
The Nansen file affords some attention-grabbing insights pushed by blockchain analytics. The core “why” remains a thriller — with the company opting no longer to speculate on the aptitude dreams or motivations on the again of the seven main addresses that accomplished a critical role in triggering the depeg of the UST algorithmic stablecoin.
