According to reports, the native stable coin of a Polkadot-based decentralized finance (DeFi) platform was taken down on Sunday after plunging 99% when hackers exploited a bug in a new liquidity pool to hit nearly 1.3 billion tokens, causing the value of the coin to plummet. A liquidity pool is a digital stack of cryptocurrency locked inside a smart contract, which creates liquidity for faster transactions on decentralized exchanges and DeFi protocols.
