Juno intended to transfer the seized tokens from the individual whale's wallet to a community-controlled wallet. However, the person making the transfer accidentally copied and pasted the wrong value, resulting in the funds being sent to a wallet address that no one can access — effectively burning the tokens.
Daniel Hwang, who helps run one of the Juno validators, said to CoinDesk, "We fucked up big time". He also offered an unusual opinion: "Validators should have due diligenced for ourselves to actually check the code we're executing and running".
Shortly after the botched transaction, the Juno community began voting on a proposal to hard fork a second time to fix their mistake.
