how to offline sign
v1.3.5 v1.3.5 419e3f2a · Merge branch 'last-135' into 'master' · 1 month ago This is a patch release that adds support for constructing and signing transactions via the API (and offline, via siac or a hardware wallet). It also includes significant changes to the HostDB's ranking algorithm; specifically, it improves protection against Sybil attacks (creating many hosts to increase chances of being selected), and better accounts for the collateral posted by hosts. Lastly, some handy utility functions were added in the form of siac utils, with the goal of creating a "Swiss army knife" for performing various Sia-related tasks.
