The world of blockchain technology is brimming with innovation, and at the heart of this ever-evolving landscape lies the Solana blockchain development. Renowned for its speed, scalability, and security, Solana has become the first choice of developers and organizations for building the next generation of decentralized applications (dApps). Within this ecosystem, tokens play a crucial role, functioning as digital assets that represent value, ownership, or access.
However, the functionality of these tokens is dependent on the underlying programs that govern their creation and management. Here's where the Token-2022 program of Solan comes into play. This program, also known as Token Extensions, serves as the new standard for building and managing both fungible and non-fungible tokens (NFTs) on Solana.

Let's now understand the difference between the two tokens and why do we need the Token-2022 program in the first place.
The Token program provides a basic framework for creating and managing both fungible and non-fungible tokens on Solana. It offers essential functionalities like minting, transferring, and burning tokens, while the Token-2022 program acts as a superset of the original Token program, inheriting all its functionalities and adding new features which we discuss in later parts in the blog.
The Token-2022 program offers a more advanced and versatile platform for building tokens compared to the original program. While the original program provides a solid foundation, Token-2022 unlocks a wider range of possibilities for developers seeking to create innovative token designs and functionalities.
The token-2022 program leverages an extension model, allowing users to add specific functionalities (extensions) on top of the core program, enhancing customizations and innovations. Here's a list of some notable Token-2022 program extensions:
Transfer Fees: Allows configuring fees based on the transferred amount, enabling innovative token economics.
Closing Mint: Permits closing the mint account when the supply reaches zero, ensuring proper token management.
Interest-Bearing Tokens: Influences how the UI displays token amounts, enabling features like accruing interest.
Non-Transferable Tokens: Creates "soul-bound" tokens that cannot be transferred to other addresses, similar to issuing a token and then freezing the account, but allows the owner to burn and close the account.
Permanent Delegate: Specifies a permanent account delegate for any token account associated with the mint.
Memo Required on Incoming Transfers: Enforces the inclusion of a memo field for incoming transfers.
Immutable Ownership: Prevents reassignment of ownership for the account, enhancing security and control.
Default Account State: Sets the default state (frozen/thawed) for newly created token accounts.
CPI Guard: Protects against certain cross-program invocation (CPI) attacks, improving security.
Transfer Hook: Allows custom logic to be executed during token transfers, enabling advanced functionalities.
