Vanity Addresses

Every token on socials.fun has a unique Solana address ending in sfun.

What Are Vanity Addresses?

Vanity addresses are Solana public keys that contain a specific pattern. For socials.fun, all token mint addresses end with the suffix sfun:

Example: 7xKXtg2CW87d97TXJSDpbD5jBkheTqA4...sfun
                                            ^^^^
                                        Vanity suffix

Why Vanity Addresses?

Brand Recognition

• Easy to identify socials.fun tokens at a glance
• Distinguishes from random tokens in your wallet
• Professional appearance on block explorers

Anti-Scam

• Harder to create fake "socials.fun" tokens
• Users can verify authenticity by checking the suffix
• Creates trust through visual consistency

Technical Achievement

• Demonstrates protocol sophistication
• Each address requires significant GPU computation to generate

How They're Generated

Finding a vanity address requires "mining" - trying random keypairs until one matches the pattern:

1. Generate random keypair
2. Check if public key ends in "sfun"
3. If no → repeat (millions of times)
4. If yes → save and use for token

Pre-Generation System

To ensure instant token creation, we maintain a pool of pre-generated vanity addresses:

Pool Status

The vanity pool typically maintains:

• Target: 100+ available addresses
• Replenish threshold: Triggers at < 50 addresses
• Generation rate: ~500 addresses per GPU batch

Address Lifecycle

1. GPU generates keypair with -sfun suffix
2. Address added to pool as "AVAILABLE"
3. User starts token creation
4. Address reserved as "RESERVED" (5 min TTL)
5. Token created → address marked "USED"
   OR timeout → address returns to "AVAILABLE"

Verification

To verify a socials.fun token:

1. Check the mint address ends in sfun
2. Verify on Solana Explorer (opens in a new tab)
3. Confirm token exists on socials.fun (opens in a new tab)

function isSocialsFunToken(mintAddress: string): boolean {
  return mintAddress.toLowerCase().endsWith('sfun');
