Summary
Dango (ticker: DNG) is a DeFi-native Layer-1 blockchain and perpetual futures exchange that raised $3.6 million in seed funding in November 2024 from Hack VC, Lemniscap, and Delphi Labs. On April 13, 2026, the protocol suffered a logic flaw exploit in its insurance fund donation contract, resulting in $1.9 million USDC being drained; approximately $410,010 was bridged to Ethereum before bridge rate limits halted further outflows. The attacker was identified as a white hat who returned all funds in exchange for a bug bounty, leaving user positions and trading functions unaffected.
