A hacker recently minted 120 million $YU tokens on the Polygon network and swiftly began unloading them across multiple blockchains.
Reports reveal that 7.71 million $YU was sold for 7.7 million USDC, with transactions routed through Ethereum and Solana via cross-chain bridges.
A hacker minted 120M $YU on Polygon and then sold 7.71M $YU for 7.7M $USDC on Ethereum and Solana via cross-chain.
The hacker still holds 22.29M $YU on Solana and Ethereum, with another 90M $YU still on Polygon that has not been bridged.

Current holdings
Despite the large-scale swap, the attacker still controls significant reserves. Approximately 22.29 million $YU remains spread across Solana and Ethereum wallets, while an additional 90 million $YU is still sitting on Polygon and has yet to be bridged out. This suggests the attacker could attempt further liquidity drains if conditions allow.
Conversion to Ethereum
Blockchain trackers further confirmed that the hacker already exchanged the 7.7 million USDC haul for 1,501 ETH, dispersing the funds into multiple wallets to obfuscate trails. This conversion highlights a familiar laundering pattern, with Ethereum often serving as a preferred exit route due to its liquidity depth.
The exploit underscores the persistent vulnerabilities surrounding cross-chain token movement. With large sums still under the hacker’s control, investors and protocols tied to $YU remain on high alert for additional sell-offs.
