Hyperbridge exploit mint 1B bridged DOT; ETH gains dem capped
Di Hyperbridge exploit bin target na Polkadot cross-chain bridge, dem use Ethereum gateway contract and ISMP flow make dem bypass state-proof verification and grab unauthorised admin control of the bridged DOT (ERC-20) token contract for ETH. After dem get control, attacker mint roughly 1 billion bridged DOT and sell part of supply. Dem collect about $237K worth of ETH, further gains stop because the bridged DOT pool liquidity thin. Polkadot confirm say impact only affect the Ethereum ERC-20 representation of DOT. Native DOT and other parachain bridges no touch. Hyperbridge pause all transactions as dem dey investigate and prepare upgrade. Market reaction soft but bearish for DOT: DOT fall about 3.56% to ~ $1.18 (close to ~$1.13 low on Feb 13, 2026). Spot show small net outflow (~$43K), while derivatives show rising perpetual activity, meaning traders fit still add speculative long exposure despite the security shock. For traders, Hyperbridge exploit remind make dem price in bridge admin-control and liquidity-provider risk. Even if on-chain losses capped by liquidity, bridge incidents fit still cause short-term sell pressure and volatility around DOT/ETH bridging flows.
Bearish
DOT drop sharp because of Hyperbridge exploit, driven by talk say sell-pressure dey around admin-control risk for bridged token. Even though on-chain impact wey dem quantify limited by thin liquidity (so the ETH wey dem fit cash out small), the event still cause uncertainty about bridge-side verification and gateway security, wey fit make traders dey risk-off for DOT/ETH bridging flows.
Short term: volatility fit continue as Hyperbridge still paused and traders dey reassess counterparty/LP exposure to bridged DOT. The small spot outflow support the bearish reaction, even though rising perpetual activity dey show speculative positioning.
Long term: if Hyperbridge deliver solid upgrade and no other bridged assets turn out vulnerable, market fit normalize. But until dem fully confirm the root cause and bridge operations resume smoothly, bridge incidents dey pressure sentiment and liquidity around bridged representations of DOT.
