An address spent approximately $600 to exploit a DOT issuance surge attack for arbitrage, profiting approximately $150,000 across blockchains.

According to Foresight News , AiYi's monitoring revealed that in the recent Polkadot attack that supposedly increased the supply of 1 billion DOT, an address starting with 0x52f70 spent only about $600 to buy low and sell high on the Ethereum mainnet, then cross-chain to the Base network via Hyperbridge, selling 503,000 DOT for 68.72 ETH, for a total profit of approximately $150,000. In this attack, the attackers actually increased the supply of 1 billion DOT, profiting approximately $236,000.
