Acala recovers 297 billion of aUSD stablecoin minted during exploit

Acala, a parachain project on Polkadot, says it has recovered about 2.97 billion from 16 addresses that minted 3 billion Acala USD (aUSD) in a security incident last Sunday. The error allowed some Acala liquidity providers to mint its native stablecoin and illegitimately move them into their control. Per the team, 99% of these “error mints” remained within addresses on the Acala network. This team halted the Acala chain and was able to freeze addresses that held the minted stablecoin.
