In a concerning turn of events for the decentralized finance (DeFi) sector, Pike Finance, a cross-chain lending protocol, has fallen victim to two consecutive exploits within a span of three days, resulting in a substantial loss of over $1.9 million in digital assets.
TLDR
- Pike Finance, a decentralized cross-chain lending protocol, suffered a $1.6 million exploit on April 30th, 2024, across Ethereum, Arbitrum, and Optimism networks.
- The exploit was due to a vulnerability in Pike Finance’s smart contract, allowing attackers to bypass admin access and withdraw funds.
- This incident followed a previous $299,127 USDC exploit on April 26th, caused by weak security measures in USDC transfer functions.
- Pike Finance is offering a 20% reward for the return of stolen funds or information leading to their recovery.
- The protocol plans to compensate affected users and investigate the exploits further.
The most recent incident, which occurred on April 30th, 2024, saw Pike Finance lose a staggering $1.6 million worth of various cryptocurrencies across the Ethereum, Arbitrum, and Optimism blockchains.
According to on-chain analytics firm CertiK, the attacker exploited a vulnerability in Pike Finance’s smart contract, allowing them to manipulate the output address and drain the contract of 479.39 ETH (worth over $1.4 million), 64,126 Optimism tokens (valued at approximately $150,000), and 99,970.48 Arbitrum coins (worth over $100,000).
The exploit’s root cause was a misalignment in Pike Finance’s smart contract storage mapping, causing the contract to behave as if it were uninitialized.
This flaw enabled the attacker to bypass admin access and upgrade the spoke contracts, ultimately facilitating the withdrawal of funds.
Attention Users:
On the 30th of April 2024, the Pike Beta protocol was exploited for 99,970.48 ARB, 64,126 OP and 479.39 ETH.
This exploit is related to the initial USDC vulnerability that was reported last week on the 26th of April.

Notably, this security breach follows a previous exploit on April 26th, 2024, where Pike Finance lost 299,127 USDC (approximately $299,127) due to weak security measures in the functions managing USDC transfers via the cross-chain transfer protocol (CCTP).
In a post-mortem report, the protocol acknowledged that inadequate protection allowed attackers to manipulate the receiver’s address and amounts, leading to the loss of USDC assets across Ethereum, Arbitrum, and Optimism networks.
In response to the latest exploit, Pike Finance has taken decisive action by offering a 20% reward for the return of the stolen funds or any information leading to their recovery.
The protocol has also expressed its commitment to investigating the breach thoroughly and has plans to compensate affected users, though the details of this compensation have not been disclosed yet.
The two successive exploits have undoubtedly raised concerns about the security measures employed by Pike Finance and the broader DeFi ecosystem.
While the protocol has acknowledged the vulnerabilities and is taking steps to address them, the incidents highlight the importance of robust smart contract auditing and the need for constant vigilance in the rapidly evolving world of decentralized finance.
As the DeFi sector continues to grow and attract more users and investments, it is crucial for protocols to prioritize security and implement stringent measures to safeguard user funds.
Incidents like these not only erode trust in the affected protocol but also cast a shadow over the entire DeFi industry, which has been striving to establish itself as a legitimate and secure alternative to traditional finance.
Moving forward, Pike Finance will need to regain the confidence of its users by thoroughly addressing the identified vulnerabilities and implementing robust security measures.
Additionally, the protocol should consider engaging with independent security auditors and penetration testing firms to thoroughly vet its smart contracts and systems.
