How to Bridge Tokens to Aptos on Liquidswap with LayerZero

·

Bridging digital assets across blockchains has become a cornerstone of decentralized finance (DeFi), enabling users to access new ecosystems, liquidity pools, and yield opportunities. One of the most efficient ways to move tokens to the Aptos blockchain is via LayerZero, an omnichain interoperability protocol. When combined with Liquidswap, Aptos’ leading decentralized exchange, this bridge offers a seamless, secure, and trustless way to transfer assets like USDC, USDT, ETH, and WETH from multiple chains.

This guide walks you through everything you need to know about bridging tokens to Aptos using LayerZero and Liquidswap—how it works, key benefits, step-by-step instructions, and common troubleshooting tips.

What Is LayerZero?

LayerZero (LZ) is not a traditional bridge. It's a foundational blockchain primitive that enables trustless, omnichain communication between over 30 supported blockchains. Unlike conventional bridges that rely on custodial validators or wrapped tokens, LayerZero uses a decentralized architecture involving two independent entities: an Oracle (like Chainlink) and a Relayer.

This dual-party verification ensures that messages—such as cross-chain token transfers—are delivered securely without any single point of failure. Because assets are never held in custody, LayerZero significantly reduces the risk of exploits that have plagued other bridges in the past.

How LayerZero Works: The Technical Edge

For two chains to communicate via LayerZero, each must host an LZ Endpoint—a suite of smart contracts that handle message transmission. Here’s how a cross-chain transfer unfolds:

  1. A user initiates a transfer on Chain A through a dApp (e.g., Liquidswap).
  2. The dApp sends transaction data to the LZ Endpoint’s Communicator module.
  3. The Validator prepares a packet and forwards it to the Network module.
  4. The Oracle (e.g., Chainlink) reads the block header from Chain A and relays it to Chain B.
  5. Simultaneously, the Relayer fetches the transaction proof from Chain A and stores it off-chain.
  6. On Chain B, the LZ Endpoint verifies that the block header (from Oracle) matches the transaction proof (from Relayer).
  7. If valid, the destination dApp executes the action—such as minting tokens on Aptos.

Only when both independent parties agree does the transaction proceed. This design eliminates the need for trusted third parties, making LayerZero one of the most secure cross-chain solutions available.

Key Advantages of LayerZero

✅ Trustless Architecture

With no centralized validators or custodial escrow, users retain full control of their assets throughout the process.

✅ Omnichain Compatibility

Supports direct communication between any two connected chains—whether Ethereum ↔ Aptos or Avalanche ↔ BNB Chain—regardless of consensus mechanisms or virtual machines.

✅ Scalability

Lightweight message verification keeps gas costs low, even on high-fee networks like Ethereum.

✅ Enhanced Security

No asset custody means no honeypot for hackers. The only theoretical attack vector—collusion between Oracle and Relayer—is mitigated by requiring these entities to be independent.

Important: Avoid Scams

LayerZero does not have a token, nor has it announced plans for an airdrop or public sale. Beware of fake Telegram groups, Twitter accounts, or websites using official branding to promote a non-existent “LZ token.” These scams often trick users into connecting wallets to phishing sites.

✅ Always verify official channels:

Never trust DMs from self-proclaimed “admins.”

Step-by-Step Guide: Bridge Tokens to Aptos via Liquidswap

Liquidswap integrates LayerZero’s bridge directly into its interface, allowing smooth transfers of supported assets from EVM chains to Aptos.

Step 1: Set Up Your Aptos Wallet

You’ll need a compatible wallet for Aptos. Supported options include:

We recommend Pontem Wallet, available as a Chrome extension. Install it securely, create your account, and safely back up your seed phrase.

👉 Get started with a reliable wallet setup for seamless DeFi access.

Step 2: Connect to Liquidswap Bridge

Visit bridge.liquidswap.com and:

  1. Accept Terms & Conditions.
  2. Click Connect.
  3. Choose MetaMask (source) and Pontem Wallet (destination).

Each wallet will prompt confirmation—no gas fee is required for this step.

Step 3: Select Source Chain and Token

Liquidswap supports seven tokens across multiple chains:

Select your source chain (e.g., BNB Chain) and token (e.g., USDT).

Step 4: Estimate Fees and Gas Options

Bridging fees vary by chain. At the bottom of the widget, check Gas on Destination:

💡 Tip: You’ll need ~0.003 APT to claim tokens + ~0.01 APT to swap—aim for at least 0.02 APT for smooth operation.

Ensure your source wallet has enough native token (ETH, BNB, etc.) to cover gas fees.

Step 5: Initiate the Transfer

Enter the amount to bridge and click Transfer. MetaMask will prompt:

Example: Bridging USDT from BNB Chain may cost ~0.01 BNB total (~$3), including gas drop.

After confirmation, wait for processing. Do not close the tab.

Step 6: Claim Your Tokens on Aptos

Once confirmed (timing varies by chain), a Claim button will appear.

Click it and confirm in Pontem Wallet (~0.003 APT gas). Your bridged tokens (e.g., USDT) will now appear in your balance.

❗ Common issue: Users often forget to claim. If your tokens aren’t visible, check if you’ve completed this step.

If the status shows “Failed,” don’t panic. Go to LayerZero Scan using the transaction hash—many “failed” transactions are actually delivered.

Step 7: Swap on Liquidswap

Now that you have USDT on Aptos:

  1. Go to liquidswap.com
  2. Connect Pontem Wallet
  3. In Swap tab, select LayerZero USDT → APT
  4. Check liquidity and price impact (<1% is ideal)
  5. Enable frontrunning protection (red lock icon)
  6. Adjust slippage (start with 0.5%)

Confirm the swap in your wallet. The airdropped APT should cover gas fees.

⚠️ Note: LayerZero USDT is different from Wormhole or Celer versions—ensure you’re swapping the correct contract.

Bridging Back to EVM Chains

Yes—you can also send tokens from Aptos back to Ethereum, BNB Chain, etc.

However:

Set Gas on Destination to None if you already have native gas (e.g., BNB) on the target chain to reduce fees.

Frequently Asked Questions (FAQ)

Q: Does LayerZero have a token?

A: No. Any claims of an “LZ token” or airdrop are scams.

Q: Why does bridging from Aptos take so long?

A: It requires 500,000 block confirmations (~3–4 days) as a temporary security measure.

Q: Do I need APT for gas when bridging?

A: Yes—but LayerZero can airdrop APT to your wallet during bridging (paid in source chain gas).

Q: Are USDT from different bridges interchangeable?

A: No. LayerZero USDT, Wormhole USDT, and Celer USDT are separate contracts on Aptos.

Q: What if my transaction fails?

A: Check LayerZero Scan with your hash. Most “failed” transactions succeed eventually.

Q: Who runs the Liquidswap bridge?

A: The bridge is powered by LayerZero technology—not operated or controlled by Pontem Network.
