Seedify Hack
What happened
On September 23, 2025, Seedify's SFUND token was exploited by DPRK-linked hackers who compromised a developer's private key to mint unauthorized tokens through the cross-chain bridge. The attack resulted in over $1.2 million in losses and caused SFUND to crash 99% from $0.43 to near zero, affecting 64,000 holders across multiple blockchains.
At approximately 12:05 UTC, North Korea state-affiliated hackers gained access to a Seedify developer's private key and exploited the OFT (Omnichain Fungible Token) bridge contract to mint unauthorized SFUND tokens on Avalanche. The attackers modified contract settings to enable unlimited minting, then bridged the tokens cross-chain to Ethereum, Arbitrum, and Base networks where they drained available liquidity pools. The majority of stolen funds were ultimately transferred to BNB Chain and sold before Seedify could contain the breach.
The primary attacker address received over $1.2 million worth of SFUND tokens and began laundering proceeds across multiple wallets. Seedify responded by coordinating with centralized exchanges to halt trading, blacklisting attacker addresses across all affected chains, revoking compromised permissions, and temporarily disabling all cross-chain bridge functionality.
