A catastrophic exploit on an Ethereum-Polkadot bridge has resulted in $1 billion worth of DOT being minted out of thin air — and then sold for just $237,000. The attacker drained the bridge's liquidity pool by manipulating the cross-chain messaging protocol, creating fake wrapped DOT tokens on Ethereum and swapping them for real assets. The price of DOT has since taken a hit, with bulls struggling to defend the $0.85 level.
How the exploit worked
The attacker targeted the bridge's minting function, which normally wraps DOT on Ethereum so it can be used in DeFi. By feeding a malicious payload into the bridge's oracle, the attacker tricked the system into minting 1 billion DOT tokens on Ethereum. Those tokens were then swapped for ETH and stablecoins across multiple DEXs, netting about $237,000 in proceeds — a tiny fraction of the token's face value. The bridge's team paused the contract about six hours after the attack, but by then the damage was done.
Market pressure on DOT
The DOT price is under pressure after the exploit. Bulls are currently defending the $0.85 level, but momentum is flatlined and spot volume is low. The attack has shaken confidence in the bridge's security, and traders are waiting to see if the team will offer a recovery plan or if more fallout is coming. The low volume suggests many are sitting on the sidelines.
What comes next
The bridge's developers have not yet released a full post-mortem, but they have said they are working with security firms to trace the stolen funds. Affected users are unlikely to see a full recovery — the attacker's $237,000 haul is a tiny fraction of the $1 billion in minted tokens, but the real assets drained from the bridge's liquidity pool are gone. The team has not announced a timeline for reopening the bridge. Until they do, DOT holders are left watching the $0.85 support level.
