The decentralized cryptocurrency exchange SushiSwap has recently been a victim of a smart contract bug, which led to the theft of about $3.3 million in Ethereum (ETH). SushiSwap is a popular and reputable exchange and this hack has taken the cryptocurrency community by surprise. In this article, we will delve deeper into the incident, the root of the cause, and the measures taken by SushiSwap to recover the funds.

According to PeckShield, a reputable crypto analytics firm, the smart contract bug was related to the contract approval process and was implemented a few weeks ago. This bug allowed the hacker to initiate a transaction and transfer 1,800 ETH. The transaction was identified by the victim, Sifu, a well-known crypto trader, who immediately reported it to the SushiSwap team. The team swung into action to investigate and understand the cause of the hack.

SushiSwap Takes Action

SushiSwap has informed its users to verify and revoke any permissions they have granted. The team provided a link through which users can check their accounts and revoke any tokens that have been approved. SushiSwap has advised users to double-check their approvals and unapprove any addresses listed for their tokens. The exchange’s CTO, Matthew Lilley, has assured users that SushiSwap is currently running bug-free and that the exposure to RouterProcessor2 has been removed from the front-end. All LPing and current swap activities are safe to do.

It is imperative that users check their approvals and remove any unauthorized access to their tokens. This is an excellent opportunity for users to rethink their security measures and possibly invest in hardware wallets that safeguard their funds against such smart contract bugs.

What This Means for the Asset

The hack has come as a big blow to SushiSwap’s reputation. Nevertheless, the team’s swift action and transparency on the matter have gone a long way in reassuring users. SushiSwap has been a vital pillar in the DeFi ecosystem and continues to be so, with innovative features and excellent user experience.

However, as we have seen in the past, hacks can cause a dip in a cryptocurrency’s value, and investors need to be on the lookout for any adverse effects on ETH’s price. It is essential that traders keep abreast of the latest developments and pay extra attention to their holdings’ performance in the near future.


The recent SushiSwap hack has once again highlighted the risks involved in investing in the cryptocurrency market. Although SushiSwap has acted promptly and ensured users’ safety, traders need to realize the importance of securing their funds. While software solutions may help, hardware wallets provide an extra layer of safety and a more secure way to keep your digital investments safe. Cryptocurrency exchange hacks can be damaging, but the community’s united response and support can help in recovering lost funds and rebuilding trust.
