The Aptos mainnet is now live, and you can finally buy $APT tokens by bridging USDC, USDT, ETH, and WETH from six different blockchains. In this comprehensive guide, we’ll walk you through every step—from setting up your wallet and using the LayerZero bridge to swapping your first tokens on **Liquidswap**, Aptos’ leading decentralized exchange. We’ll also cover bridging fees, troubleshooting tips, and what you can do with $APT once you’ve acquired it.
What Is LayerZero?
LayerZero is a cutting-edge interoperability protocol that enables secure, trustless communication between blockchains. Unlike traditional bridges that rely on third-party validators or centralized relays, LayerZero uses a decentralized oracle and relayer system to verify cross-chain messages, making it both secure and efficient.
This omnichain technology allows developers to build cross-chain applications (dApps) and transfer assets in a single transaction—without locking funds in vulnerable smart contracts. That’s why Pontem Network chose LayerZero to power the Liquidswap Bridge, ensuring fast, safe transfers of USDC, USDT, ETH, and WETH between Aptos and major EVM chains.
Currently supported networks include:
- Ethereum
- BNB Chain
- Avalanche
- Arbitrum
- Optimism
- Polygon

Why Use the LayerZero Bridge?
While centralized exchanges like Binance and Coinbase list $APT with fast withdrawals, there are several scenarios where using the LayerZero bridge is more advantageous:
- $APT isn’t available on your preferred exchange.
- You want to trade at a better price via Liquidswap.
- You’re a DeFi user who keeps assets across multiple chains.
- You want full control over your tokens without relying on custodial services.
Bridging gives you direct access to the Aptos ecosystem—unlocking DeFi, NFTs, staking, and more.
Step-by-Step Guide: Bridge Tokens & Buy $APT
Step 1: Install Pontem Wallet & Connect to Mainnet
Start by installing Pontem Wallet, a non-custodial wallet built specifically for the Aptos blockchain. It supports over 20 dApps and integrates seamlessly with Liquidswap.
👉 Get started with one of the most user-friendly Aptos wallets today.
To install:
- Visit the Chrome Web Store and download Pontem Wallet.
- Create your wallet and securely back up your seed phrase.
- Ensure the network is set to Aptos Mainnet (not testnet).
Other compatible wallets include Petra, Martian, and Fewcha—though note that Liquidswap currently doesn’t support Fewcha.
Step 2: Import USDC, USDT, and WETH Tokens
Before receiving bridged assets, import the corresponding token contracts into your wallet:
- LayerZero USDC:
0xf22bede237a07e121b56d91a491eb7bcdfd1f5907926a9e58338f964a01b17fa::asset::USDC - LayerZero USDT:
0xf22bede237a07e121b56d91a491eb7bcdfd1f5907926a9e58338f964a01b17fa::asset::USDT - LayerZero WETH:
0xf22bede237a07e121b56d91a491eb7bcdfd1f5907926a9e58338f964a01b17fa::asset::WETH
You can find updated token addresses in Pontem’s Coin Registry.
Note: If you don’t have any APT for gas, the bridge will automatically send a small amount to cover registration fees when you initiate your first transfer.
Step 3: Connect to Liquidswap Bridge
Head to bridge.liquidswap.com and:
- Accept the Terms & Conditions.
- Click Connect Wallet.
- Choose MetaMask as your source wallet and Pontem Wallet as the destination.
Each wallet will prompt you to confirm the connection—this step costs no gas.
Step 4: Select Source Chain & Check Gas Fees
The bridge supports:
- USDC: Ethereum, Arbitrum, Optimism, Polygon, Avalanche
- USDT: Ethereum, BNB Chain, Avalanche, Polygon
- ETH/WETH: Ethereum, Arbitrum, Optimism
Bridging Fee Estimates (as of latest data):
| Chain | Approximate Fee |
|---|---|
| Ethereum | 0.0025 ETH |
| Arbitrum | 0.0025 ETH |
| Optimism | 0.0017 ETH |
| Polygon | 4.7 MATIC |
| Avalanche | 0.21 AVAX |
Always verify current fees in the bridge interface under “Gas on Destination.” Adjust between None/Medium/High settings to estimate costs.
Ensure your source wallet has enough native tokens (ETH, MATIC, AVAX, etc.) to cover gas—otherwise, you’ll see a “Not enough native for gas” error.
Step 5: Choose Token & Amount, Then Bridge
In the bridge widget:
- Select your source chain (e.g., Polygon).
- Pick the token (e.g., USDC).
- Enter the amount.
- Confirm in MetaMask.
Depending on your APT balance and token registration status, one of three scenarios may occur:
Scenario A: You Have Enough APT & Token Is Registered
- Transaction confirms directly.
- Wait for completion (tracked via progress bar).
Scenario B: No APT in Wallet (First-Time User)
- The bridge auto-sends a small APT airdrop to cover gas.
- After bridging, go to Step 6 to claim your tokens.
Scenario C: Some APT but Token Not Registered
- You’ll be prompted to register the token first.
- If registration fails, refresh and retry.
Step 6: Claim or Check Your Balance
Once the progress bar shows “Complete”:
If Token Was Already Registered
- Open Pontem Wallet—your bridged tokens should appear instantly.
If You Haven’t Registered the Token
- Click either wallet address in the bridge widget.
- Go to the Unclaimed tab.
- Click Claim and confirm the transaction.
Your wallet will now display both the bridged asset (e.g., USDC) and a small amount of APT for gas.
⚠️ If the status says “Failed,” don’t panic. Check the transaction hash on LayerZero Scan—it may still be delivered. Refresh or wait a few minutes.
Step 7: Swap for $APT on Liquidswap
Now that you have USDC or WETH on Aptos:
- Go to liquidswap.com.
- Connect Pontem Wallet.
- Navigate to Swap.
Select:
- Top field: USDC (LayerZero)
- Bottom field: APT
- Enter amount and review estimated output.
- Adjust slippage (default: 0.5%) via gear icon if needed.
- Click Swap, confirm in popup, then sign in Pontem Wallet.
If you get an “out of gas” error:
- Click Set Optimal Gas.
- Wait during high network load—the required gas fluctuates.
Within seconds, your $APT will appear in your wallet.
Bridging Back to EVM Chains
Yes—you can bridge assets back from Aptos to Ethereum, Polygon, and others using the same interface.
However:
- Gas fees may be high during peak times.
- Transfer times vary—up to 3 days for Ethereum due to finality delays.
- Always save your transaction hash for tracking on LayerZero Scan.
What Can You Do With $APT?
Once you own $APT, here are powerful ways to use it:
- Hold (HODL) – Stake your belief in the future of high-performance Layer 1 blockchains.
- Provide Liquidity – Deposit equal value of APT + USDC/WETH into Liquidswap pools and earn trading fees.
- Stake or Liquid Staking – Earn rewards while maintaining liquidity through upcoming staking protocols.
- Buy NFTs – Explore emerging NFT marketplaces on Aptos.
- Lend & Borrow – Participate in DeFi lending platforms launching on mainnet soon.
Check Pontem Wallet’s dApp directory regularly for new opportunities.
Frequently Asked Questions (FAQ)
Q: Do I need APT for gas before bridging?
A: No. If your wallet has zero APT, the LayerZero bridge automatically sends a small amount to cover token registration and claiming fees.
Q: Can I bridge directly from Solana?
A: Not yet via LayerZero. The current bridge supports EVM chains only (Ethereum, Polygon, etc.). Wormhole-based bridges may offer Solana support later.
Q: Why does bridging back take so long?
A: Cross-chain finality delays—especially with Ethereum’s consensus layer—can extend return transfers up to 72 hours. Plan accordingly.
Q: Are bridged tokens different from native ones?
A: Bridged USDC/USDT/WETH are fully functional on Aptos but carry “LayerZero” prefixes. They work identically in dApps like Liquidswap.
Q: What if my transaction fails?
A: First, check the status on LayerZero Scan. Most “failed” statuses resolve automatically after delivery confirmation. Never resend unless funds are confirmed missing.
Q: Is there a minimum or maximum bridge amount?
A: There’s no official cap, but very small amounts may not be cost-effective due to gas fees. Always ensure bridging costs are justified by transaction size.
