Example of CAKE bridging to Aptos
sendFromfunction sendFrom(address _from, uint16 _dstChainId, bytes32 _toAddress, uint _amount, uint _minAmount, LzCallParams calldata _callParams) external payable;| Name | Type | Description |
|---|---|---|
| _from | address | From address. This should be the address calling the CakeProxyOFT |
| _dstChainId | uint16 | 108 for Aptos mainnet |
| _toAddress | bytes32 | The destination address on Aptos |
| _amount | uint256 | Amount of CAKE in WEI. Please note that amounts less than 1e-8 will get dusted |
| _minAmount | uint256 | Minimum receiving amount. We do not charge any fee in CAKE. But this should not be larger than _amount after being rounded down to 8 decimals |
| _callParams | tuple | A set of call parameters used to define bridging behaviours. Continue reading for more detail. |

}| Name | Type | Description |
|---|---|---|
version | uint16 | Default is 2 |
| dstGasLimit | uint | Default is 200000 |
| dstNativeGasTransferAmount | uint | Amount destination native gas token to airdrop. Use 0 if you don't need the bridge to convert BNB and airdrop you APT |
| dstNativeGasTransferAddress | bytes | The destination address that receives native gas tokens on destination chain. |
