The world of decentralized finance (DeFi) has once again been shaken by news of a cyberattack. Nemo Protocol, a yield platform built on the Sui blockchain, announced that it had lost approximately $2.4 million worth of stablecoins due to a security vulnerability over the weekend.
In the incident, first reported by security firm PeckShield, the attacker reportedly transferred stolen USDC tokens from Arbitrum to the Ethereum network. This moved the assets into an ecosystem where they could be more easily moved and difficult to monitor.
All smart contracts have been halted
The Nemo team confirmed the attack in a statement on Telegram on Monday, announcing the incident to the community:
“Dear Nemo community, last night there was a security incident affecting the Market pool. We are investigating the issue and have temporarily halted all smart contract activity. We will share new information as we receive it.”
It is also noteworthy that the platform has entered a previously scheduled maintenance period. Nemo had previously announced that the application would be under maintenance on Monday and Tuesday. Therefore, the attack's emergence coincided almost simultaneously with the maintenance period.
Are the assets safe?
Nemo Protocol emphasized that the attack only affected a specific pool and that the assets held in the vaults were safe. However, a clear explanation has not yet been released regarding the root cause of the incident. This uncertainty has shaken investor confidence and once again highlighted the ongoing security vulnerabilities in DeFi protocols.
Following the attack, the total locked assets (TVL) on the platform experienced a significant decline. According to DeFiLlama data, Nemo Protocol's TVL fell from $6 million to $1.53 million. This decline indicates that investors were rapidly withdrawing their funds from the platform.
What is Nemo Protocol?
Nemo Protocol is a yield optimization and yield trading platform built on the Sui blockchain. It offers users the ability to tokenize their investments. The platform divides assets into Principal Tokens (PT) and Yield Tokens (YT), allowing users to buy and sell these tokens, hedge future returns, or take speculative positions.
While yield tokenization, in particular, is becoming increasingly popular in the DeFi world, Nemo Protocol was one of the prominent projects in the Sui ecosystem. However, the recent incident may cause investors to re-evaluate their trust in such new projects.
Billions of dollars worth of assets have been lost in recent years due to smart contract vulnerabilities and protocol flaws. The transparency and freedom offered by decentralized finance also create attractive opportunities for malicious actors.
