Solana: How to handle both SPLs and native SOL token in my contract?

Management of Solana and SPL tokens in the contract: Guide

Solana Blockchain (Dapp) on Solana Blockchain, Solan (Solan token) and SPL (Solana Price List). When they have different use in this article,

Understand the problem

In Solana, you cannot use another token as a stake or deposit. When one SPL may not be compatible with SOL, which leads to potential problems during installation and use.

Recommended approach: Using a single token in both cases

One contracted as a primary stake or deposit. This token can keep both devices and allow you to easily treat your interactions.

Here’s an example of how to build this:

SOL token : Use Solan-specific activities.

Package SOL to support other devices

In order for this approach to work, you need to pack SOL. This packaging token ** is called “token wrapping”. In Solana’s “Unwrap” function, you can determine the token cover for the devices.

Here’s an example of how to create a token cover:

`Sol



Pragma solidity ^0.8.0;

Wrapper contract {

    Public _wrapperaddress;

    The title of public _soltokenaddress;

    Constructor (address _wrapparaddress) public {

        _wrapperaddress = _wrapperaddress;

        _soltokenaddress = sol; // new Sol token cover

    }

    Function UNW -DIAP (Sol _astet, Uint256) External Clean Returns (Address, Uint256) {

        You need (_asset! = Address (0), "Ewrap: The device is zero");

        You need (_wrapperaddress == _soltokenaddress, "UNW -DISTAP: WrapPrapk title does not match");

        // pack the SOL token and give it back with the value specified

    }

}

The benefits of a single token

The use of a single token has many benefits for both SPL and native Sol tokens:
