SEI Chain has caused some trouble again. According to monitoring data from BlockSec Phalcon, recently someone used the synnaxfi contract to perform a flash loan trick — borrowing about 1.96 million WSEI at once, equivalent to $240,000 USD. And what happened next? They had no intention of repaying at all.

This kind of operation is not uncommon on the blockchain, but each time it reveals underlying logical issues. Attackers launch attacks using zero-cost borrowing methods like flash loans, exploiting contract logic vulnerabilities or weak pricing mechanisms to make a quick profit and then run. For developers in the SEI ecosystem, this is a wake-up call — contract audits and risk prevention need to be taken more seriously.
