Solana security mainnet

Solana Security & Mainnet

This skill provides security guidance and helps users understand the risks and safeguards when working with blockchain networks, especially mainnet operations involving real value.

Core Security Principles

Rule 1: Test on Devnet First

Always test on devnet before mainnet. Devnet has:

• Free test SOL (no real value)
• Identical behavior to mainnet
• Zero financial risk
• Perfect for learning and testing

Practice: Test every workflow on devnet before attempting mainnet.

Rule 2: Start With Small Amounts

When moving to testnet or mainnet:

• Send tiny test amounts first (0.01 SOL, not 1 SOL)
• Verify the address works and receives funds
• Only increase amounts after successful tests
• Never send your entire wallet at once

Why: Addresses can be wrong, contracts can have bugs, mistakes happen. Small amounts limit damage.

Rule 3: Verify Addresses Multiple Times

Before sending anything:

• Copy the address carefully
• Check it's pasted correctly (no extra characters)
• Verify the first 4 and last 4 characters match
• Test with small amount first
• Only use addresses you trust

Common mistake: Typo in address = funds lost forever (blockchain transactions can't be reversed).

Rule 4: Never Share Private Keys

Your private key is like your password and PIN combined:

• Never paste it anywhere
• Never share with anyone, even support
• Never type it in browsers
• Keep it in a secure file or hardware wallet
• If compromised, move funds to a new wallet immediately

If someone has your private key, they control your funds.

Rule 5: Use Dedicated Wallets

Create separate wallets for different purposes:

• Testing wallet: For devnet/testnet experiments (can lose it)
• Staging wallet: For small mainnet tests
• Main wallet: For real funds (store offline if possible)

Why: Limits damage if a wallet is compromised or lost.

Rule 6: Understand Fee Costs

Know what you're paying:

• Transaction fees: 0.00005 SOL ($0.0001)
• Token account creation: 0.002 SOL ($0.002)
• Program interaction: Varies, usually <0.01 SOL
• Total cost is usually tiny, but not free

Before mainnet: Ensure you have enough SOL for fees plus the actual transfer.

Network Comparison

Aspect	Devnet	Testnet	Mainnet
Real value	No	No	YES
Get SOL	Free airdrop	Faucet	Purchase/earn
Behavior	Matches mainnet	Nearly mainnet	Production
Reset	Occasional	Rare	Never
Best for	Learning	Testing	Real operations
Risk	Zero	Very low	HIGH

Recommendation for non-technical users:

1. Devnet: Learn and experiment
2. Testnet: Real behavior, no risk
3. Mainnet: Only after full understanding

Mainnet Safeguards

Why We Require /solana-accept-risk

This plugin requires explicit risk acceptance before mainnet operations because:

1. Blockchain is permanent: Transactions can't be reversed or recalled
2. User error is common: Wrong address, lost private key, etc.
3. No customer service: No bank to call and reverse a mistake
4. Real money at stake: Mainnet uses real SOL worth real money

What You're Accepting

By running /solana-accept-risk, you confirm:

• ✓ You understand transactions are permanent
• ✓ You've tested on devnet first
• ✓ You're using a dedicated testing wallet
• ✓ You accept responsibility for mistakes
• ✓ You won't blame the plugin if you lose funds due to user error

Risk Levels

Low Risk (Safe on Devnet, OK on Testnet)

• Querying balances
• Viewing transactions
• Analyzing accounts
• Simulating transfers (without executing)

No real loss possible, good for learning

Medium Risk (Test thoroughly before mainnet)

• Sending small test amounts
• Creating token accounts
• Swapping small amounts
• Staking or delegating

Real loss possible but limited by amount. Test with tiny amounts first.

High Risk (Mainnet expert operations)

• Sending large amounts
• Using new contracts
• Automated operations
• Bridging between networks

Large loss possible. Expert knowledge required.

Pre-Mainnet Checklist

Before running any mainnet operation, verify:

• You've tested on devnet at least once
• You ran /solana-accept-risk and accepted the terms
• Your network shows mainnet-beta (check /solana-network)
• Your wallet has SOL for fees plus the transfer amount
• The recipient address is correct (triple-check)
• You're using a dedicated wallet (not your main funds)
• You've simulated the transaction first
• You understand what the transaction does

If any box is unchecked, don't proceed.

Common Mistakes & How to Avoid

Mistake	How to Avoid
Sending to wrong address	Copy/paste carefully, verify first 4 & last 4 chars, test with small amount
Insufficient balance	Check balance with /solana-network before sending
Lost private key	Use hardware wallet, write down seed phrase, store securely
Mainnet without testing	Always test on devnet first, multiple times
Huge transfer amount	Start small, verify it works, then increase
Using new contracts	Stick to established programs, avoid brand new ones
Not reading prompts	Read every message Claude sends, confirm details

Security Tools & Best Practices

Simulation Before Execution

Always ask Claude to "simulate this transaction first" before executing:

• Shows you what will happen
• Confirms it will succeed or explains failure
• Costs nothing (no real funds involved)

Pattern:

1. User: "Simulate transferring 0.1 SOL to [address]"
2. Claude: [Shows what will happen]
3. User: "Looks good, execute the transfer"
4. Claude: [Executes and confirms]

Hardware Wallets

For serious mainnet use, consider a hardware wallet:

• Keeps private key offline
• Signs transactions securely
• Can't be hacked remotely
• Examples: Ledger, Trezor, Solflare (cold storage)

Multi-Sig Wallets

For large amounts, use multi-signature wallets:

• Requires 2+ signatures to execute
• Protects against single point of failure
• Examples: Squads, Gnosis Safe

Regular Backups

• Write down your seed phrase
• Store securely (encrypted, offline)
• Keep multiple copies in different locations
• Never store digitally unencrypted

When to Ask for Help

Reach out to support if you:

• Don't understand what something does
• See an error you don't recognize
• Suspect something is wrong
• Are about to make a large transaction (ask Claude to review)
• Lost access to your wallet
• Think your key is compromised

Red Flags & Scams

Watch out for:

• Anyone asking for your private key (never, ever share)
• "Too good to be true" opportunities (yield farms, etc.)
• Fake websites (check URL carefully)
• Unknown token airdrops (could be scams)
• Pressure to act fast (legitimate operations never rush)
• Requests to move funds urgently

If something feels wrong, it probably is.

Recovery After Mistakes

Wrong Address (Can't Recover)

If you sent to the wrong address:

• The blockchain is permanent
• Funds are gone unless the receiving address owner sends back
• Contact the recipient if known
• This is one of the most common blockchain mistakes

Lost Private Key (Can Lose Access)

If you lost your private key:

• You can't access that wallet anymore
• Create a new wallet
• Move funds from a backup wallet if you have one
• This is why backups matter

Compromised Key (Immediate Action)

If you think your key was stolen:

• Move funds to a new wallet immediately
• Stop using the compromised wallet
• Don't share details about what was compromised
• Learn from the incident

When to Use Mainnet vs Testnet

Use Devnet When:

• Learning blockchain concepts
• Testing new workflows
• Experimenting with contracts
• Teaching someone else
• Have zero experience

Use Testnet When:

• Want real network behavior
• Testing before mainnet
• Have some experience
• Minimal risk acceptable

Use Mainnet When:

• Fully understand the operation
• Have tested extensively on devnet/testnet
• Accepted risk with /solana-accept-risk
• Using small amounts initially
• Have secure key management

Key Takeaway

Blockchain is powerful but permanent. Mistakes can't be fixed. The responsibility is 100% on you:

• Solana is secure (the network is safe)
• But user error is common (addresses, keys, etc.)
• Always test on devnet first
• Start small on mainnet
• Read everything Claude writes before confirming
• Never rush decisions

Your funds = Your responsibility. Take it seriously.
