Introduction to Buying Aptos Tokens ($APT)
With Aptos mainnet live, users can now trade $APT on Liquidswap by bridging assets like ETH, USDC, or USDT. Pontem Network’s integration with LayerZero enables seamless cross-chain transfers between Aptos and six EVM-compatible blockchains.

What Is LayerZero?
LayerZero is an omnichain interoperability protocol enabling trustless asset transfers between blockchains. Unlike traditional bridges, LayerZero ensures:
- Single-transaction transfers (no multiple approvals).
- Guaranteed message delivery with minimal fees.
- Support for any smart contract language.
Popular applications like Stargate Finance leverage LayerZero for composable bridging.
Step-by-Step Guide: Bridging ETH or USDC to Aptos
Why Use the LayerZero Bridge?
While $APT is available on exchanges like Binance, bridging is ideal if you:
- Prefer on-chain DeFi over centralized platforms.
- Hold assets on Ethereum, BSC, or Polygon.
- Want to interact with Aptos dApps using stablecoins.
Step 1: Install Pontem Wallet
Download the Pontem Wallet Chrome extension and connect to Aptos mainnet.
Step 2: Import Tokens (WETH, USDT, USDC)
Add these tokens to Pontem Wallet using their Aptos contract addresses:
- WETH:
0xf22bede...17fa::asset::WETH - USDC:
0xf22bede...17fa::asset::USDC - USDT:
0xf22bede...17fa::asset::USDT

Step 3: Connect to Liquidswap Bridge
- Visit Liquidswap Bridge.
- Connect MetaMask (source) and Pontem Wallet (destination).
Step 4: Select Source Chain and Gas
Choose a chain (e.g., Polygon for USDC) and ensure you have enough native gas tokens (e.g., MATIC).
Estimated Bridging Fees:
| Chain | Fee (Approx.) |
|-------------|--------------|
| Ethereum | 0.0025 ETH |
| Polygon | 4.7 MATIC |
| Avalanche | 0.21 AVAX |
Step 5: Choose Token and Amount
Select the token (e.g., USDC) and enter the amount.
Step 6: Execute the Bridge
- If you have APT: Confirm the transaction in MetaMask.
- If you lack APT: The bridge auto-airdrops enough APT for gas.
Step 7: Swap Bridged Tokens for $APT
- Connect to Liquidswap.
- Swap USDC/WETH for $APT (slippage: 0.5–1%).
Bridging Back to EVM Chains
LayerZero supports reverse bridging, but:
- Fees vary by chain (e.g., Ethereum transfers may take 3 days).
- Always save your transaction hash for tracking on LayerZero Scan.
What Can You Do with $APT?
- Provide liquidity on Liquidswap.
- Stake in DeFi protocols.
- Trade NFTs or lend on Aptos dApps.
FAQs
How long does bridging take?
- Typically 5–30 minutes, but Ethereum-to-Aptos transfers may take longer.
What if my transaction fails?
Check LayerZero Scan—your funds are safe if marked "Delivered."
Can I bridge other tokens besides USDC/ETH?
Currently, only WETH, USDC, and USDT are supported.
