$2.4M USDC Stolen from Sui-Based Yield Protocol Nemo in Exploit

Nemo, a yield optimization protocol on the Sui blockchain, suffered a $2.4 million exploit on Monday, highlighting ongoing security risks in decentralized finance (DeFi).

The attacker stole USDC, the dollar-pegged stablecoin issued by Circle, and reportedly bridged the funds from Arbitrum to Ethereum, according to blockchain security firm Peckshield.

Nemo allows users to tokenize their staked assets into Principal Tokens (PT) and Yield Tokens (YT), enabling trading, hedging, or speculation on future yields. Following the breach, the protocol’s total value locked (TVL) plunged to $1.53 million from over $6 million, per DeFi analytics platform DeFiLlama.

The incident underscores that despite growing institutional participation in crypto, vulnerabilities in DeFi protocols remain a persistent challenge.
