How to onramp USDC into WebAuth and mint Metal Dollar (XMD)
Amari Market settles in Metal Dollar (XMD). Here is how to bring USDC into your WebAuth wallet and mint XMD so you are ready to collect.
Why you need XMD
Every purchase, listing, and payout on Amari Market is denominated in Metal Dollar (XMD), the reserve-backed stablecoin on XPR Network. XMD is minted one-to-one from stablecoins like USDC, so the fastest way to get collection-ready is to bring some USDC into your wallet and convert it. Because it tracks the US dollar, one XMD is worth roughly one dollar.
Step 1: Set up WebAuth
If you have not already, install the free WebAuth wallet from the App Store, Google Play, or use it on the web at webauth.com, and create your human-readable account name. This is the wallet that will hold your USDC, your XMD, and everything you collect on Amari.
Step 2: Onramp USDC into WebAuth
You can buy USDC with a card directly inside WebAuth using its built-in onramp, or buy it on an exchange and withdraw it to your WebAuth account name. If you withdraw from an exchange, make sure you select the XPR Network (Proton) network so the funds arrive in your WebAuth wallet — sending on the wrong network can lose the funds.
Step 3: Mint XMD from your USDC
Open the Metal Dollar app from metaldollar.com and connect your WebAuth wallet. Choose to mint, select USDC as the stablecoin you are depositing, and confirm the amount. XMD is minted one-to-one, so depositing 50 USDC gives you 50 XMD, minus only a fraction of a cent in network fees. Approve the transaction in WebAuth and your XMD balance appears in seconds.
Step 4: Start collecting on Amari
With XMD in your WebAuth wallet, head to Amari Market, click Connect Wallet, and approve the login. You can now buy any listed collectible, album, or access pass instantly. When you want to cash out later, the same Metal Dollar app lets you redeem XMD back to USDC one-to-one.
