Solana: Non transferable spl token mint without extensions

Creating non-transferable SPL token on Solana without extension

As the popularity of Solana and its ecosystem continues to grow, developers are exploring new ways to create innovative decentralized applications (dApps). One such concept is to create non-transferable SPL tokens without relying on token extensions. In this article, we will explore the possibilities of creating a non-transferable SPL token using the old token standard.

What is a non-transferable token?

A non-transferable token (NTT) allows users to hold and trade tokens without being able to transfer them from one account to another. This means that once minted, a token cannot be transferred or sold, making it a unique asset in the ecosystem.

Creating a non-transferable SPL token using the old token standard

The Solana blockchain uses its own token standard known as the SPL (Solana Plasma) token standard. The SPL token standard allows the creation of non-transferable tokens using the old token program ID (TOKEN_PROGRAM_ID). This means developers can use their existing code to create new SPL tokens without having to rebuild the entire project.

Token Program ID

TOKEN_PROGRAM_ID is a critical component when creating NTT on Solana. Specifies the custom token standard used, which includes the SPL token standard. To create an NTT, developers must provide a custom token program ID that references the old token standard. This can be achieved by:

• Creating a new file named spl_token_program_id.json in the token_programs/ directory of their Solana project.

• In this file they must define their own token standard and its corresponding program ID.

Here’s an example of what the file might look like:

{

  "name": "My own SPL token",

  "program_id": "my_custom_spl_token_program"

}

• The token_programs directory should contain a new subdirectory called spl_token_programs/, which contains the ID file of your own token program.

• To compile and implement NTT, developers can use `solana-program compiler’ to generate the necessary code for their own SPL token standard.

Advantages of using the old token standard

Creating NTT on Solana without expansion offers several advantages:

• Easier Maintenance: Developers don’t have to worry about maintaining complex extension interfaces or rebuilding the entire project.

• Faster Development: A custom token standard can be created and implemented quickly, reducing the time spent on development and testing.

• Community Adoption: Existing users of the old ID token program can adopt the new SPL token standard, increasing community interest and user engagement.

Conclusion

Creating a non-transferable SPL token without extensions is possible using the old token standard. By providing a custom token program ID that references the legacy SPL token standard, developers can build innovative decentralized applications on Solana. This approach offers several advantages, including easier maintenance, faster development, and greater community adoption. Whether you’re creating a new dApp or optimizing an existing one, building NTT on Solana without extensions is an attractive alternative for those who want to stay up-to-date with the latest trends in DeFi and blockchain technology.
