Around.WS (Around Wallet Services) is an easy-to-use Bitcoin transaction website for anonymously and privately transferring funds between Bitcoin wallets, addresses and bank accounts.
At the moment, users of Around Wallet Services need to submit their private key, when they request a transfer of their Bitcoins from one address to another address.
Although not ideal, it does not pose a security risk to users. Around Wallet Services only uses a received private key once, during the transfer of Bitcoin, and then the private key is discarded and forgotten, forever.
To remedy this, the next version of Around Wallet Services will feature user signatures, so that users will have the ability to sign transactions themselves, and just send their transaction signatures to Around Wallet Services, instead of their private key, which will result in the safest possible Bitcoin user experience.
