How scoring works →Summary
PlayDapp is a South Korean blockchain gaming platform and NFT marketplace founded in 2017 and operating on Ethereum and Polygon. In February 2024, an attacker who had obtained PlayDapp's contract deployer private key via a phishing email added themselves as an authorized minter and minted 1.79 billion PLA tokens across two events, representing a nominal loss of approximately $290 million. The platform subsequently suspended the PLA smart contract and executed a 1:1 migration to a new token (PDA) to remediate the illegitimate token supply.
