A Closer Look at the SynapLogic Incident
Recent reports have emerged about suspicious transactions linked to SynapLogic on the Base network. These incidents raised significant concerns within the crypto community, as around 144,000 SYP tokens were minted unexpectedly through unusual activity.
What Happened?
According to reliable on-chain monitoring systems, an attacker exploited a flaw in SynapLogic’s business logic. This allowed them to mint large amounts of SYP tokens using a series of linked transactions. Interestingly, while the tokens were created, they remained locked within the attacker’s contract and were not sold or swapped, ensuring minimal market impact.
The issue arose when multiple transactions showed abnormal behavior. Analysis revealed that the attacker’s wallet was initially funded via Tornado Cash on the Ethereum network, before transferring funds to the Base network using a bridging service. From there, the attacker conducted flash-loan-supported transactions to mint tokens multiple times, exploiting a flaw in the token system’s referral mechanism.
The Exploit: How It Worked
The problem was not due to stolen private keys or a traditional hack, but rather a loophole in SynapLogic’s purchase system. Users purchasing SYP tokens could input a list of referral addresses to receive rewards. However, the system failed to validate the input adequately. The attacker exploited this by listing their own address multiple times, effectively earning rewards far beyond the intended design.
For example, in one scenario, the attacker listed their own wallet address 31 times, resulting in receiving 310% of their initial purchase amount. In total, this flaw led to an estimated $88,000 worth of funds being drained from the contract.
Damage Contained
Despite the attack, the newly minted SYP tokens were locked as vesting tokens, which cannot be moved or sold until certain preconditions are met. This design feature ultimately protected other token holders from significant market disruptions. Additionally, SynapLogic promptly paused the affected contract to contain the issue and released updates to prevent future exploits of this nature.
Lessons Learned
The SynapLogic team’s quick response and transparent communication helped mitigate wider panic within the community. Their statement assured users that the situation was resolved and that all funds remained secure. This incident underscores the importance of thorough testing, robust auditing processes, and continuous monitoring in decentralized systems to prevent similar vulnerabilities.
