## Attacker Mints $1 Billion Polkadot Tokens on Ethereum, Steals $250,000

A critical vulnerability was exploited in the Ethereum-Polkadot bridge, allowing an attacker to forge a cross-chain message and bypass state proof validation. This exploit granted the attacker admin control over the bridged DOT token, enabling them to mint an enormous supply—effectively $1 billion worth—though they were only able to sell $237,000 before being detected. (source) This breach highlights ongoing security risks associated with cross-chain bridges, a critical infrastructure for interoperability in DeFi. For the Polkadot ecosystem, such incidents can severely undermine investor confidence, as vulnerabilities in bridge contracts can lead to significant token dilution and loss of funds. While the immediate market impact was limited due to the attacker’s inability to liquidate the full amount, persistent security flaws may dampen DOT’s price performance and increase scrutiny from both users and regulators.

## Polkadot (DOT) Drops 2.3% as CoinDesk 20 Index Trades Lower

Polkadot's DOT token declined by 2.3%, reflecting broader weakness across the CoinDesk 20 index, which saw most major cryptocurrencies trading lower. This period was marked by risk-off sentiment in the market, with assets like Ripple (XRP) also underperforming. (source) DOT’s underperformance in line with the overall market suggests that macroeconomic trends and investor sentiment are driving price action rather than project-specific developments. Such declines can test the resilience of DOT’s support levels, and may offer entry points for long-term investors if the underlying fundamentals remain strong.

In contrast, Cosmos declined, highlighting divergence among major crypto assets.
