How to buy Aptos (APT) via Petra Wallet? (DApp guide)

Setting Up Petra Wallet

1. Visit the official Petra Wallet website and download the browser extension for Chrome or Firefox.

2. Click “Add to Chrome” or “Add to Firefox” and confirm the installation prompt.

3. Open the Petra icon in your browser toolbar and click “Create a new wallet”.

4. Securely back up your 12-word recovery phrase by writing it down on paper and storing it offline.

5. Confirm the seed phrase in the correct order to verify ownership and complete setup.

6. Set a strong password for wallet unlocking—this does not recover your funds but protects local access.

Connecting to Aptos Network

1. Launch Petra Wallet and ensure it displays “Aptos Mainnet” in the top-right corner.

2. If it shows “Testnet”, click the network selector and choose “Mainnet” from the dropdown list.

3. Verify the network ID matches 0x1 — this is the canonical Aptos Mainnet chain identifier.

4. Check that your account address begins with 0x followed by 64 hexadecimal characters.

5. Copy your wallet address using the clipboard icon next to the address display for later use.

Funding Your Wallet with APT Tokens

1. Navigate to a centralized exchange such as Binance, OKX, or Bybit that supports APT trading pairs.

2. Purchase APT using fiat (USD, EUR) or stablecoins like USDT or USDC.

3. Initiate a withdrawal and paste your Petra wallet address into the recipient field.

4. Select “Aptos Network” as the withdrawal blockchain—sending via any other chain will result in permanent loss.

5. Confirm the transaction fee shown and approve the withdrawal; tokens typically arrive within 1–3 minutes.

6. Return to Petra Wallet and refresh the balance view—APT should appear under the token list with accurate decimal precision.

Interacting with APT DApps

1. Go to a verified Aptos-based decentralized application such as Pontem Swap, Liquidswap, or Tortuga Finance.

2. Click “Connect Wallet” and select “Petra” from the available options.

3. Approve the connection request in the Petra popup window without signing any transaction at this stage.

4. Once connected, navigate to the swap interface and select APT as either input or output token.

5. Enter the desired amount and review slippage tolerance—default settings are usually safe for small trades.

6. Click “Swap” and confirm the transaction signature in Petra when prompted; wait for block confirmation.

Frequently Asked Questions

Q: Can I send ETH or ERC-20 tokens to my Petra wallet?A: No. Petra only supports Aptos-native assets. Sending Ethereum or Ethereum-based tokens will result in irreversible loss.

Q: Why does my APT balance show zero after depositing?A: Ensure you selected “Aptos Network” during withdrawal and that the transaction hash appears on Aptoscan.io. Refresh Petra manually if needed.

Q: Is it possible to import an existing private key into Petra?A: Petra does not support private key import. It only allows recovery via the original 12-word mnemonic phrase.

Q: What happens if I lose my Petra password?A: The password is only for local wallet unlocking. Your funds remain accessible using the 12-word recovery phrase on any compatible Aptos wallet.
