Solana Features
Understanding Solana-specific token capabilities and the SPL Token standard.
SPL (Solana Program Library) tokens are the standard for fungible tokens on Solana, similar to ERC-20 tokens on Ethereum but with key advantages:
Advantages
- Ultra-low transaction fees (fractions of a penny)
- Fast confirmation times (400ms average)
- Built-in rent exemption for token accounts
- Native freeze/thaw capabilities
- Efficient batch operations
Key Concepts
- Mint Account: Defines the token properties
- Token Account: Holds tokens for a specific owner
- Associated Token Account: Default token account per wallet
- Mint Authority: Can create new tokens
- Freeze Authority: Can freeze/unfreeze accounts
Solana tokens have two main authority types that control different aspects of the token:
Mint Authority
Controls the ability to create new tokens, increasing the total supply.
Freeze Authority
Allows freezing/unfreezing individual token accounts in emergency situations.
Immutable Tokens
Once mint authority is revoked, the token supply becomes permanently fixed. This provides strong guarantees to token holders about supply inflation.
Account Rent
Token accounts require a small SOL deposit (rent) to exist on-chain. This prevents spam and ensures accounts remain accessible.
Program Upgrades
The SPL Token program is immutable and battle-tested, providing security guarantees that token behavior won't change unexpectedly.
Our SPL Token Creator handles the complex technical details:
Mint Account Creation
Creates the token mint with specified decimals and authorities
Associated Token Account
Creates the recipient's token account automatically
Initial Mint
Mints the specified supply to the recipient account
Metadata Creation
Adds token metadata using the Metaplex standard
Authority Management
Optionally revokes mint authority for immutable supply
