Sujet: Re: [Libbitcoin] comparison of sx OFFLINE TRANSACTIONS to functionality in satoshi wallet jsonrpc for raw transactions
sx is not a wallet though, it is a tool for sysadmins to work with the
bitcoin network, keys and internals. I use it often in debugging.
Maybe you're better served by these instead?
