Fast facts

  • Over the weekend, exploiters breached a bug in the platform’s liquidity pool to mint 130 million stablecoins, resulting in a severe fund pool imbalance and pushing aUSD to lose its peg to the U.S. dollar.
  • Acala held a community vote on Monday proposing to burn nearly 1.3 billion coins to offset the breach. Acala Dollar is a stablecoin issued by Polkadot-based decentralized finance project Acala Network.
  • Acala also continues to identify and report wrongly minted aUSD that has been swapped with other tokens or added to liquidity pools.
  • Sixteen wallets executed these outflow transactions, said Acala Network in its Twitter post.
  • Acala did not reveal how much it lost but crypto analysts on Twitter estimated Acala’s loss at US$1.6 million.
