anchored·dFds3D…ZjBJSummary
Acala Network is a Polkadot-native DeFi hub offering a multi-collateralized stablecoin (aUSD), liquid staking, and an AMM DEX. On August 14, 2022, a misconfiguration in a newly deployed liquidity pool caused 3.022 billion aUSD to be erroneously minted, triggering a 99% depeg; approximately 98% of the erroneous tokens were subsequently recovered and burned via community governance votes. The incident raised significant concerns about the protocol's claimed decentralization after the team unilaterally placed the network in maintenance mode and froze token transfers without an on-chain vote.
