Solidity Contract Integration

https://github.com/bifrost-finance/slpx-contracts/tree/main/contracts

If you want to integrate SLPx in your contract, please see a sample code.

Among them are calls to the mintVNativeAsset and mintVAsset methods

Because of the use of XCM technology, the result of the call is not real-time, you'd better put the SLPx call at the end of your contract logic.
