The exploiter minted over 115 duovigintillion USDC deposit receipts but then redeemed only $2.4 million worth.
A hacker managed to drain over $6 million from the decentralized finance (DeFi) protocol Delta Prime by minting an arbitrarily large number of deposit receipt tokens.
According to data from block explorer Arbiscan, the attacker minted over 115 duovigintillion Delta Prime USD (DPUSDC) tokens in the initial attack, which is more than 1.1*10^69 in scientific notation.
DPUSDC is a deposit receipt for USDC (USDC) stablecoin held at Delta Prime. It is intended to be redeemable at a 1:1 ratio for USDC.
