< p >
This tool will take a < i > geth< / i > (or crowdsale) JSON wallet, decrypt it and
send all its funds to < a href = "http://etherscan.io/address/0x3474627d4f63a678266bc17171d87f8570936622#code" > this contract< / a > ,
which will:
< / p >
< ul >
< li > On the ETH branch — send the funds back to the original address< / li >
2016-08-05 03:12:50 +03:00
< li > On the ETC branch — send the funds to the provided target address (for example, a < a href = "https://www.poloniex.com" > Poloniex< / a > deposit address)< / li >

< h3 > Disclaimer:< / h3 >
< p >
I threw this together in couple of hours, mainly to split my own ether
and test my < i > ethers-wallet< / i > library (which is still missing features
and is itself not ready for production use). Testing has been fairly minimal
beyond trying it on a few wallets. < b > Use this at your own risk.< / b >
