On August 26-27, 2025, BetterBank on PulseChain was exploited via its reward mechanism using flash loans to manipulate liquidity pools, create a fake ERC20 paired with PDAIF, and trigger ESTEEM minting. ~$5M was stolen; the attacker later returned $2.7M, leaving net losses of ~$1.4M. The issue had been flagged during audit but dismissed.

The PulseChain-based defi project BetterBank was exploited by an attacker who took advantage of a vulnerability that allowed them to mint arbitrary tokens, some of which they then swapped for ETH. The attacker later returned around $2.7 million of the stolen assets, having cashed out around $1.4 million.
