# Buy
Buying crypto directly from your home screen takes 6 screens, from picking what you want to buy to paying for it. This guide walks through the exact example shown in the design: buying USD₮ with Naira.
***
## 1. Select what you're buying
Tapping **Buy** from your home screen (alongside the **Receive**, **Send**, and **Swap** tabs) opens two stacked cards: **You pay** (defaults to your local currency, e.g. Naira) and **You get** — tap the **You get** card to pick which crypto asset you want to buy.
## 2. Enter an amount
Once you've picked an asset (e.g. **USD₮** on the Optimism network), you'll see your current balance and a live exchange rate — for example *"1 NGN ≈ 0.00073 USD₮."* Both amount fields start at **0**, and **Review buy** stays disabled until you type something in.
## 3. Watch the conversion update live
As you type an amount into **You pay** (e.g. **100,000** Naira), **You get** updates automatically using the live rate (e.g. **73.27** USD₮). Once there's a valid amount, **Review buy** becomes active.
## 4. Review before you commit
Tapping **Review buy** shows a clean summary: the amount you'll receive front and center (**73.27 USD₮**), paid for with Naira. Underneath, a details card confirms where it's going — your own **Shiga Wallet** — and restates the amount you're paying (**100,000**).
Tap **Place Order** to lock in the trade.
## 5. Pay for your order
This is the key step: **"73.27 USD₮ reserved for 100,000 Naira."** You're given a one-time bank transfer instruction — an account number, bank name, and account name — to pay from your own bank app. A countdown timer (starting at **10:00**) shows how long that account stays valid for this specific transaction.
This bank account is generated just for this transaction and expires after the countdown. If it expires before you pay, you'll need to start a new order.
Once you've sent the transfer, tap **Done** — or **View Order** to keep watching the order's status.
## 6. Success
Once your payment is received, your crypto arrives automatically and you'll see **"73.27 USD₮ purchased"** with a confirmation checkmark. From here, tap **Done** to return to your wallet, or **View transaction** for the full record.
