GROESTLCOIN DEVELOPMENT RELEASE

Sparrow-GRS 1.7.1

What am I?

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.
