Token Program
Overview
Solana supports two main token standards:
SPL Token (Classic) — the original, universal token program used across the Solana ecosystem.
Token-2022 — an upgraded version with advanced features like transfer fees, interest-bearing accounts, and more flexibility.
Toolther allows you to create both types, depending on your project’s goals.
1. SPL Token (Classic)
Description
The classic SPL token is powered by the program ID TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA. It is the default and most widely supported fungible token standard on Solana.
Key Features
Universal compatibility — supported by all wallets (Phantom, Solflare, Backpack, etc.) and all DEXs.
Core authorities — mint, freeze, and update authorities.
Predictable minting — fixed decimals and supply configuration.
Immutability option — ability to revoke authorities for total decentralization.
Limitations
No built-in transfer fees.
No programmable transfer hooks.
No native confidentiality or compliance layers.
Best for
Meme tokens or basic community coins.
NFT utility tokens and reward systems.
Tokens requiring full backward compatibility with all existing Solana tools.
2. Token-2022
Description
Token-2022 extends the SPL standard via the program ID TokenzQd9LqZ.... It introduces extensions for customizable tokenomics and compliance features.
Key Features
Transfer Fees — collect a small percentage of each transaction.
Interest-Bearing Accounts — accrue interest directly in the token account.
Transfer Hooks — allow logic for approval, restriction, or validation.
Permanent Delegates — assign other accounts to act on behalf of the owner.
Non-Transferable Tokens — perfect for credentials, badges, or governance.
Confidential Transfers (coming soon) — private balances and transactions.
Advantages
Flexible and programmable tokenomics without custom smart contracts.
Integrated compliance controls and whitelisting features.
Future-ready standard for upcoming DeFi and regulated use cases.
Limitations
Wallet and DEX support still growing.
Slightly more complex setup.
Limited third-party analytics tools at the moment.
