1) Bridging from Aptos to other chains takes a minimum of 500,000 blocks to confirm
The number of block confirmations is a security measure introduced by LayerZero because Aptos is a new blockchain, and this restriction may be lifted in the future. Bridging can be completed in three days, but there’s no way to speed it up manually.
- The bridge on Liquidswap and on the LayerZero website are the same
Inaccurate article about the non-existent LayerZero airdrop keep repeating that you have to first bridge assets over the Aptos Bridge on the LayerZero website and then over the one on Liquidswap. These are the same thing! In reality, Liquidswap’s widget is the LayerZero bridge – the colors are different, but it’s the same bridge.
3) The bridge is run by LayerZero, not by Pontem Network
4) You can airdrop yourself APT for gas, but it’s not free
When you bridge USDT or other tokens from Ethereum or another chain to Aptos for the first time, you’ll need a little APT to register them in the wallet and claim them. Having to register a token before transacting with it is a standard requirement on Aptos, and it requires some gas. You’ll also need APT for your first swap on Liquidswap (e.g. USDT to APT). So where do you get APT for gas if your wallet is completely empty?
LayerZero has a solution: it allows you to airdrop yourself a little bit of APT if you don’t have any yet. You’ll need to pay for this airdrop on the origin chain, and that constitutes a considerable chunk of the bridge fee. You can adjust the APT airdrop amount by clicking on Gas on Destination in the bridging window.
