Buy CYRUS on Mobile
CYRUS is sold through a bonding curve on Base. You pay with USDC, and the price rises gradually as more of the sale allocation is sold.
Step One: Open the App From Inside Your Wallet
Do not open Safari or Chrome. Use the browser built into your wallet app. That is how your wallet connects automatically - no QR codes, no WalletConnect prompts.
Find the browser in your wallet app, then type app.cyrus.gold in the address bar.
Where to find the browser in each wallet:
| Wallet | How to get to the browser |
|---|---|
| Rabby | Tap the DApp icon in the bottom nav bar |
| Base (formerly Coinbase Wallet) | Tap the Browser tab in the navigation bar |
| MetaMask Mobile | Tap Explore in the bottom nav, then the browser icon at top right |
| Rainbow | Tap the globe icon in the bottom nav bar |
| Trust Wallet (Android only) | Tap the Browser or DApps tab in the bottom nav |
Once the app opens, tap Connect and your wallet links automatically. No QR code. No copying addresses.
Before You Start
You need:
- a mobile wallet with in-app browser installed
- USDC on Base in your wallet
- a small amount of Base ETH for gas
Step-by-Step
- Open your wallet app
- Go to the built-in browser (see the table above for your wallet)
- Type
app.cyrus.goldand open it - Tap Connect - your wallet connects automatically
- Confirm the wallet is on Base
- Enter the USDC amount you want to spend
- Review the CYRUS amount shown
- Tap Approve if this is your first purchase (one-time permission for your USDC)
- Tap Confirm to complete the purchase
- Wait for the transaction to confirm
- Check that CYRUS appears in your wallet balance
First Purchase Advice
- Start with a small test amount - try $5 or $10 first
- Make sure the app shows you are spending USDC, not another asset
- Keep some ETH in your wallet for gas after buying
Once the first purchase works, you can come back and buy more.
Why Not Safari or Chrome?
If you open app.cyrus.gold in a regular browser, the app has no way to reach your wallet directly. It falls back to showing a QR code or WalletConnect flow - which is more steps, easy to do wrong, and confusing if you are new.
The in-wallet browser already has your wallet. The app just detects it and connects. It is the simplest path.

If Something Looks Wrong
Stop before tapping Confirm if:
- the wallet shows the wrong chain
- the app is asking for the wrong asset
- the amounts look wrong
- anything is asking you to type your recovery phrase
No legitimate step in this flow will ever ask for your recovery phrase or seed words. If anything asks for that, close the app immediately.
If CYRUS Does Not Show in the Wallet
Some mobile wallets, especially MetaMask Mobile, may fail to add the token to your wallet automatically even when the purchase succeeds.
That does not mean the transaction failed. Your CYRUS is still in your wallet address on Base. You may just need to import the token manually.
