Sparrow-GRS 1.7.9 released

Previous topic - Next topic


Sparrow-GRS is a modern desktop Groestlcoin wallet application supporting most hardware wallets and built on common standards such as PSBT, with an emphasis on transparency and usability.

Sparrow-GRS does not hide information from you - on the contrary it attempts to provide as much detail as possible about your transactions and UTXOs, but in a way that is manageable and usable.
However, Sparrow-GRS is also unique in that it contains a fully featured transaction editor that also functions as a blockchain explorer. This feature not only allows editing of all of a transaction's fields, also easy inspection of the transaction bytes before broadcasting.
