Get a Wallet

To interact with smart contracts in the EVM, you need a valid EVM-compatible wallet. Use one of the following wallets to connect to the EON network:

• Cobalt
• MetaMask

Cobalt is a web browser extension wallet available using Chrome or Brave. Like a physical wallet, Cobalt holds ZEN cryptocurrency and tokens. Connecting Cobalt to the EON network (Gobi Testnet) allows you to interact with the EON sidechain (Horizen’s EVM) and dApps.

Cobalt allows you to create and restore wallets from any EVM-compatible network. Once you have configured the network in Cobalt, you can set a link to the corresponding block explorer to view your account transaction history.
