The Aku Mint Was Far From Dreamy


AkuDreams, an NFT collection created by Micah Johnson, experienced a smart contract bug during its mint that locked away $34 million of ETH – which can no longer be accessed by the Aku team nor NFT buyers.

According to 0xInuarashi, an anonymous crypto developer on Twitter, the contract fell prey to three bugs. The first was corrected, and the second led to $34 million in ETH being locked forever.


  1. The contract was written so that a single user sending a malicious contract call could freeze the refund capability of the Aku mint. However, this was eventually rectified by the hacker, who wrote on chain that “you guys [the Aku team] publicly acknowledge that the exploit exists, I will remove the block immediately.” Notably, this bug was hinted at on April 22nd by @notchefbob, but the team denied anything was wrong at the time.

  2. The team structured their own withdrawal tool in a way that miscounted bids, requiring a total of 5,495 bids to withdraw the $34 million in ETH, when they only received 3,669.


The Aku team is currently working on a plan to rectify the situation. Pass holders for the Aku mint will receive a .5 ETH refund on Monday or Tuesday. (Ironically, this refund is delayed due to Aku using a bank for their company Treasury). As of mid-afternoon on Sunday, the team is rewriting their minting contract, with plans to airdrop the NFTs at some point in the near future.

“Im so sorry. Im so sorry to the Aku family. I care so deeply about the Aku family, I let you all down & I’m so sorry,” wroteAku creator Micah Johnson on Twitter.
