What happened?
On June 15, 2025, the price of $ZKJ plummeted about 80–83%, from ~$2 to ~$0.30, within hours — triggered by a liquidity drain attack on the ZKJ/KOGE pool on PancakeSwap.
Several large wallet addresses, including those connected to Wintermute, withdrew millions of tokens and sold them on exchanges, triggering cascade liquidations.
Polyhedra's response:
Launching an aggressive buyback program to stabilize the price and restore community confidence.
Injecting ~$30 million in USDT/USDC/BNB into the DEX pool to add liquidity.
Investigating thoroughly and planning to strengthen protection mechanisms against similar attacks.
