To locate your SWT wallet public address, go to https://swarm.city and login to your profile.
Click on your profile name to display the public address associated with the wallet. Users can share the public address (referred to as public key in the DApp) with others to receive any ERC-20 token.
Just beneath the public address you can view the private key associated with this public address. This private key unlocks this public address, and anyone who has access to this key can access your tokens. DO NOT SHARE YOUR PRIVATE KEY. Be sure to store your private key in a safe place.
