Visit the HMS dApp

.Note: You will require some Ethereum on BASE network for gas fees.

Step 1:
Connecting to the dApp.

A) Connect your EVM-compatible wallet (e.g., MetaMask) to the HMS dApp. The MetaMask browser extension works well with Brave or Chrome.
 

B) Select the “Browser wallet” from the menu and wait for the pop-up message from MetaMask (or whichever wallet you’re using). DO NOT select “MetaMask” or “Other Wallets” directly from the menu! Sign in to approve the connection.
 

C) Make sure you have changed the network to BASE via "Select Chain" tab.
