Rusty Kaspa CLI Wallet Restricts Blind Signing of Non-Default Sighashes in PSKBs
Rusty Kaspa's command-line wallet codebase has introduced a change that halts the automatic signing of partially signed Kaspa bundles (PSKBs) requesting loose signature hash types. The tool now requires explicit opt-in via a dedicated flag before signing inputs with any sighash other than SIG_HASH_ALL.
Why it matters for Kaspa
In shared-signing workflows, non-standard sighashes can allow counterparty modification of outputs after a signature is provided. While the fix is merged in main, it is limited to the CLI client and has not yet been deployed in a general binary release.
