Ordinals founder Casey issued a reminder on the X platform, urging users to upgrade their ord wallet to version 0.21.2 as soon as possible. This update fixes a serious vulnerability that may result in accidental loss of runes when using the "ordwalletsend" feature due to incorrect creation of change output. Casey explained that when the input UTXO contains multiple runes (A and B), sending rune A may result in rune B being mistakenly sent. This update also added the wallet address message signature function and fixed the casting progress display issue. We have not yet received any reports of asset losses caused by this vulnerability from users. @ftor26
