How to Bridge - EVM <> Aptos

Bridge CAKE between EVM chains and Aptos

The following guide uses BNB Chain as an example of an EVM chain. The same process can be applied to Ethereum.

Bridge CAKE from BNB Smart Chain to Aptos

1 - Make sure your wallet supports both BNB Smart Chain and Aptos Mainnet. Or you have both of the wallets installed in your browser.

Then open the PancakeSwap CAKE Bridge

2 - First, we need to connect our BNB Smart Chain wallet.

Click "Connect" and choose the wallet you prefer under the "EVM" section. Then confirm and approve in your wallet popup. (As of writing, only MetaMask is supported. Support for more wallets is coming soon)

3 - Then, we need to connect our Aptos wallet.

In the wallet connect modal, choose the wallet you prefer under the "Aptos" section. Then confirm and approve in your wallet popup.

4 - Click the "v" in the upper token selection field and choose "CAKE".

5 - Input the number of CAKE you want to bridge to Aptos.

6 - If your Aptos wallet is freshly created and doesn't have any APT (Aptos Coin) balance. We recommend keeping the "gas on destination" option at its default. The bridge will deposit a small amount of APT to your wallet, not only to help you kickstart your journey on Aptos, but you will also need APT for gas to register and claim your bridged CAKE.

Altering this option might cause bridging to fail.

7 - Click "Transfer" to initiate the bridging transaction and confirm via the wallet confirmation pop up.

Please note that depending on the condition on your BNB Smart Chain wallet and Aptos wallet. You may need to approve multiple wallet confirmations. For example if you are bridging CAKE to Aptos for the first time, you will need to:

• Approve CAKE spending on the bridging contract (coming from your BNB Smart Chain wallet)

• Register CAKE (coming from your Aptos wallet)

For more detail please check out this breakdown.

8 - Sit back and relax. It should only take a few minutes. Once the bridging is complete, CAKE will be deposited into your Aptos wallet. You can track the progress by the progress bar.

Bridging CAKE to Aptos for the First Time

Bridging CAKE to Aptos wallets requires registration and claim transactions. This is done to enhance user security and is unique to Aptos.

If you already have APT (Aptos Coin) in your wallet:

You’ll be prompted to register CAKE on your Aptos wallet if it’s not registered yet. No additional claim transaction is needed in this case.

If you don’t have APT (Aptos Coin) in your wallet:

After the bridge transaction completes, you’ll need to manually claim your CAKE. To cover the gas fees for claiming, APT tokens will be sent to your Aptos wallet from your source wallet.

These registration and claim steps only apply the first time you interact with a token on Aptos. Subsequent transfers of the same token won’t require these actions.

Before bridging CAKE to Aptos for the first time, ensure your Aptos address has enough APT for gas fees. For more details, check out Aptos’s explanation here: https://theaptosbridge.com/faq#registering-claiming-assets
