Parity's goal is to be the fastest, lightest, and most secure Ethereum client. We are developing Parity using the sophisticated and
cutting-edge Rust programming language. Parity is licensed under the GPLv3, and can be used for all your Ethereum needs.
Parity comes with a built-in wallet. To access [Parity Wallet](http://127.0.0.1:8080/) simply go to http://127.0.0.1:8080/. It
Parity comes with a built-in wallet. To access [Parity Wallet](http://web3.site/) simply go to http://web3.site/ (if you don't have access to the internet, but still want to use the service, you can also use http://127.0.0.1:8180/). It
includes various functionality allowing you to:
- create and manage your Ethereum accounts;
- manage your Ether and any Ethereum tokens;
