🪙 How Solana Tokens Work

Before we dive into security, let's understand the basics.

What is a Token?

A token on Solana is like a digital currency or asset. Popular examples include:

• SOL - Solana's native currency
• USDC - A stablecoin pegged to the US dollar
• JUP - Jupiter's governance token
• BONK - A popular meme coin

Anyone can create a token on Solana. The token creator is initially given special powers called "authorities." These authorities control important aspects of the token.

The Two Critical Authorities

When someone creates a token on Solana, they receive two important controls:

1. Mint Authority - The power to create (mint) new tokens
2. Freeze Authority - The power to freeze token accounts

Think of it like this:

• Mint Authority is like having a money printing machine
• Freeze Authority is like being able to lock someone's bank account

🖨️ What is Mint Authority?

Mint Authority gives someone the power to create new tokens out of thin air.

Why This Matters

Imagine you buy a token that has 1 million total supply. You think you own 1% because you have 10,000 tokens. But if the creator still has mint authority, they could create 100 million more tokens tomorrow!

Suddenly, your 10,000 tokens represent only 0.01% of the supply instead of 1%. The value of your tokens has been massively diluted.

Example: The Dilution Scam

1. A creator launches "FAKE Token" with 1 million supply
2. They sell half (500,000 tokens) to investors
3. The token price rises to $1 each
4. Suddenly, the creator mints 99 million more tokens
5. They sell these new tokens, crashing the price
6. Your investment becomes nearly worthless

What to Look For

✅ Safe: Mint authority is null or renounced

• This means no one can create new tokens
• The supply is fixed forever

❌ Risky: Mint authority is still active

• The creator can dilute your investment at any time
• Common in scam tokens

❄️ What is Freeze Authority?

Freeze Authority gives someone the power to freeze any wallet's token balance.

Why This Matters

If someone has freeze authority over a token:

• They can prevent you from selling your tokens
• They can lock your tokens in your wallet forever
• You become completely trapped

Example: The Freeze Scam (Honeypot)

1. You find a token that looks promising
2. You buy some tokens
3. The price goes up - you're excited!
4. You try to sell... but the transaction fails
5. The creator has frozen your wallet
6. Meanwhile, they sell their tokens and disappear
7. You're left holding worthless, unmovable tokens

This is called a honeypot - you can get in, but you can't get out.

What to Look For

✅ Safe: Freeze authority is null or renounced

• No one can freeze your tokens
• You can always sell when you want

❌ Risky: Freeze authority is still active

• Your tokens could be frozen at any time
• Classic honeypot setup

🔒 What Does "Renounced" Mean?

When someone "renounces" an authority, they permanently give up that power.

How Renouncing Works

1. The token creator has mint and freeze authority
2. They send a special transaction to the blockchain
3. The authority is set to "null" (nothing)
4. This cannot be undone
5. No one, including the creator, has that power anymore

Why Legitimate Projects Renounce

Serious projects renounce their authorities to:

• Build trust with investors
• Prove they can't manipulate the supply
• Demonstrate long-term commitment
• Get listed on reputable exchanges

The Renouncement Transaction

You can actually verify renouncement on-chain. When authorities are renounced:

• The mint authority address shows as null
• The freeze authority address shows as null
• This is permanently recorded on the blockchain

🚨 Common Token Scams

1. Rug Pull

The classic scam:

1. Creator launches a token with hype
2. Investors buy in, price rises
3. Creator sells all their tokens at once
4. Price crashes to zero
5. Creator disappears with the profits

Protection: Check if the creator holds too many tokens (insider concentration).

2. Honeypot

As described above:

1. Token looks normal and trades well
2. When you try to sell, transactions fail
3. Only the creator can sell
4. Your money is trapped

Protection: Check freeze authority and test with small amounts first.

3. Slow Rug (Mint Dump)

A longer-term scam:

1. Token launches with "limited" supply
2. Creator gradually mints new tokens
3. They sell these new tokens slowly
4. Price gradually declines
5. By the time investors notice, it's too late

Protection: Check if mint authority is renounced.

4. Fake Renouncement

Some scammers claim they've renounced but haven't:

1. They make an announcement saying "renounced!"
2. But they never actually sent the transaction
3. They still have full control
4. Investors trust them based on lies

Protection: Always verify on-chain, not just social media claims.

🛡️ How to Check Token Security

Method 1: Use RugCheck

RugCheck is Solana's leading security analysis tool.

Steps:

1. Go to rugcheck.xyz
2. Paste the token's mint address
3. Review the security report

What RugCheck Checks:

• ✅ Mint authority status
• ✅ Freeze authority status
• ✅ Holder concentration
• ✅ Liquidity lock status
• ✅ Contract vulnerabilities

Understanding the Score:

• Good - Low risk, authorities renounced
• Warning - Some concerns, be cautious
• Danger - High risk, avoid

Method 2: Check on Solscan

Solscan is a Solana block explorer.

Steps:

1. Go to solscan.io
2. Search for the token mint address
3. Click on the "Token" tab
4. Look for "Mint Authority" and "Freeze Authority"
5. Both should show "null" for safety

Method 3: Use Birdeye

Birdeye shows token analytics and security info.

Steps:

1. Go to birdeye.so
2. Search for the token
3. Check the "Security" section
4. Look for authority status

✅ Token Security Checklist

Before buying any token, verify these points:

Essential Checks

Additional Red Flags

⚠️ Warning Signs:

• Anonymous team with no track record
• Promises of guaranteed returns
• Pressure to buy quickly ("limited time!")
• No website or documentation
• Copy-paste marketing from other projects
• Disabled selling in DEX pools
• Social media accounts created recently

---

🔍 Understanding Holder Distribution

Besides authorities, you should check how tokens are distributed.

What is Holder Concentration?

This measures how many tokens the top wallets hold.

Example:

• Token has 1 million supply
• Top 10 wallets hold 800,000 tokens (80%)
• This is very concentrated and risky

Why It Matters

If a few wallets hold most tokens:

• They can dump and crash the price
• They control the market
• Small holders have no power

Healthy Distribution

• Good: Top 10 hold < 20% (excluding DEX pools)
• Caution: Top 10 hold 20-35%
• Danger: Top 10 hold > 35%

💧 Liquidity and Liquidity Locks

What is Liquidity?

Liquidity is the tokens in a trading pool that allow buying and selling.

Without liquidity:

• You can't sell your tokens
• There's no market for the token

What is a Liquidity Lock?

A liquidity lock means:

• The tokens in the pool are locked in a smart contract
• The creator can't remove liquidity
• Trading can continue safely

Checking Liquidity Locks

Tools to verify liquidity locks:

• Fluxbeam Locker
• RugCheck LP Lockers
• Streamflow Vesting

What to Look For:

• Lock duration of at least 6 months
• Significant percentage of LP tokens locked
• Lock cannot be cancelled early

🏆 Best Practices for Safe Trading

1. Always Do Your Own Research (DYOR)

Never buy a token just because:

• Someone on social media recommended it
• The chart is going up
• There's hype or FOMO

2. Start Small

When trying a new token:

• Buy a very small amount first
• Try to sell it immediately
• If that works, you know it's not a honeypot

3. Use Multiple Tools

Don't rely on just one security check:

• Use RugCheck for comprehensive analysis
• Verify on Solscan for on-chain data
• Check Birdeye for trading data

4. Trust On-Chain Data

Social media can lie. Blockchain cannot.

• Verify everything on-chain
• Screenshots can be faked
• Transactions are permanent proof

5. Set Limits

Protect yourself from loss:

• Never invest more than you can lose
• Diversify across multiple tokens
• Take profits when you can
