Zeroweight is a super liteweight commandline bitcoin wallet written in golang. It can be used as a package/api or as a stand alone wallet.

###Commands: # use => $zeroweight createWallet [encryptionKey|password] # => $zeroweight send [toAddress] [BTC amount] [password] # => $zeroweight balance [password]

use $history -c to eleminate password stored in bash history

###Installing as stand alone wallet:

$ export $PATH=$GOPATH/bin:$PATH
$ go get github.com/KeshavZbhide/zeroweight
$ zeroweight 

make sure your $PATH contains $GOPATH/bin. Or else just install it by moving $GOPATH/bin/zeroweight to /usr/local/bin

$ sudo mv $GOPATH/bin/zeroweight /usr/local/bin

###Installing as a golang package: $ git clone https://github.com/KeshavZbhide/zeroweight.git $ mv zeroweight $GOPATH/src $ cd $GOPATH/src/zeroweight $ find . -type f | xargs sed -i "" "s|package main|package zeroweight|g" The last command changes the name of the package to zeroweight, since the initial version is a command-line wallet and the package is named "main", now

import "zeroweight"

should work.

####tx.go: tx.go exports essential functions that can be used construct a minimum wallet. tx.go does not download the block chain.

###Exported functions: #####1. Tx(privateKey string, to string, amount float64) (string, error) Tx builds a hex encoded transaction that can be submited to a bitcoin node.

#####2. Balance(publicKey string) (float64, error) Balance returns the balance of the address (public key)

#####3. GenRandPrivateKey() string genrates randomized private key. this should be called to genrate a new wallet address.

#####4. GetPublicKey(privateKey string) string gets the corresponding public key of the private key, usualy genrated by GenRandomPrivateKey.

#####5. SubmitTransaction(tx string) string Submits the output genrated from Tx to blockchain.info/pushtx. There is no error values, but if the function is successfull it will return "Transaction submited"

refer to the comments in tx.go for simple use cases.

####warning: $zeroweight createWallet creates a encrypted file 'zeroweight.wal' in user's home directory. It contains the private key requrired to make transactions. Losing this file will lead to loosing all your bitcoins. BE VERY CAREFULL.
