Polter Finance, a decentralized lending platform, has been forced to pause operations after a devastating flash loan attack drained its platform of $12 million. The hack, which highlights vulnerabilities in smart contracts and decentralized finance (DeFi) protocols, has sent shockwaves across the crypto community.

What Happened: The Flash Loan Attack
On November 17, Polter Finance experienced an exploit targeting its newly launched SpookySwap (BOO) market. A faulty oracle price mechanism allowed the hacker to manipulate prices, leading to significant losses for the platform. Web3 security firm TenArmor confirmed that the breach resulted from this price manipulation, marking yet another high-profile exploit in the DeFi sector.
The platform was paused soon after the exploit was identified.
Bridges were notified.
We identified wallets involved and traced it to Binance.
We are still investigating the nature of the exploit.
We are in the processing of contacting the Authorities.

The attacker’s strategy was typical of flash loan exploits. They borrowed a large sum through a flash loan, manipulated asset prices temporarily, and executed a series of trades to drain liquidity from the platform.
Tracing the Stolen Funds
Polter Finance’s team quickly traced the stolen funds to wallets on Binance, one of the world’s largest crypto exchanges. To recover the funds, the protocol reached out to Binance and local law enforcement in Singapore. Additionally, Polter Finance sent an on-chain message to the hacker, proposing a negotiation and offering impunity in exchange for returning the funds.
At the time of writing, the hacker has not responded to the offer.
The Founder’s Response
The pseudonymous founder of Polter Finance, known as Whichghost, filed a formal police report with Singaporean authorities. Verified through the country’s digital identity system, Singpass, Whichghost detailed the extent of the losses, which included $223,219 of personal funds.
In the report, the founder stated:
“I believe that my platform’s newly deployed smart contract (for BOO token lending) has been exploited, causing the unauthorized transactions.”
Community Reaction and Criticism
While Polter Finance is actively investigating the hack, some members of the crypto community have raised concerns about potential insider involvement. The skeptics argue that the nature and scale of the breach may indicate internal malfeasance.
Adding to the speculation, the BOO market—a key component of the hack—had a valuation of just $3,000, making it a curious target for such a massive exploit.
Efforts to Recover the Funds
In collaboration with the Security Alliance Information Sharing and Analysis Center (SEAL-ISAC), Polter Finance aims to track the hacker and recover the stolen assets. SEAL-ISAC specializes in cybersecurity and forensic investigations, bringing an added layer of expertise to the case.
What Is at Stake?
The attack has had a devastating impact on Polter Finance’s total market size, which included:
- $7.87 million in Fantom (FTM)
- $1.03 million in wrapped USD Coin (USDC)
- $251,000 in Magic Internet Money (MIM)
- $2.1 million in Stader sFTMX
The hack also raises concerns about the safety of DeFi platforms and the need for better smart contract audits.
Lessons for the DeFi Sector
The Polter Finance hack underscores the critical importance of securing DeFi protocols:
- Rigorous Smart Contract Audits: Developers must subject new contracts to comprehensive audits before launch.
- Better Oracle Mechanisms: Decentralized platforms should implement robust oracles to avoid price manipulation.
- Emergency Protocols: Having a contingency plan can mitigate the fallout from such attacks.
- Insurance Coverage: Platforms should consider integrating DeFi insurance options for user protection.
The Polter Finance hack serves as a cautionary tale for DeFi developers and users. As the sector continues to grow, the risks associated with untested smart contracts and decentralized platforms also increase. With law enforcement and SEAL-ISAC involved, Polter Finance remains hopeful for fund recovery, though the path ahead is uncertain.
The incident emphasizes the need for greater transparency, security, and user education in the DeFi ecosystem. As the community watches closely, Polter Finance’s handling of this crisis will likely set a precedent for future responses to DeFi vulnerabilities.
