The Acala Network’s aUSD stablecoin depegged by over 99% over the weekend and required the Acala group to stop briefly a hacker’s wallet, raising issues about its claim of being decentralized.
On Aug. 14, a hacker took advantage of a bug on the iBTC/aUSD liquidity swimming pool which led to 1.2 billion aUSD being minted without security. This occasion crashed the USD-pegged stablecoin to a cent, and in reaction, the Acala group froze the mistakenly minted tokens by putting the network in upkeep mode.
The relocation likewise stopped other functions such as swaps, xcm (cross-chain interactions on Polkadot), and the oracle pallet cost feeds up until “further notice”

Community members have actually kept in mind the paradox of Acala’s claims about aUSD’s censorship-resistance considering that the procedure froze funds so promptly. Twitter user Gr33nHatt3R.dot explained on Aug. 14 that decisions “would have to go to governance to be ‘decentralized’ finance.”
“If Acala centrally controls that decision is this really DeFi?”
A member of the job’s Discord channel usafmike proposed rolling back the chain to reverse the token mints entirely, however was challenged by skylordafk.dot, another member who stated such an action would “set a harmful precedent.”
As of the time of composing, the network was still in upkeep mode to obstruct all token transfers, however the group verified that the bug had actually been repaired. The wallets that got mistakenly minted aUSD have actually been determined, and 99% of them were still on Acala which leaves the possibility that they might be obtained by the community if it votes to do so.
