Launching a token on Solana has never been easier: a few clicks on pump.fun and the token exists. What hasn’t become easier is keeping the money around it safe. A typical launch now involves a dev wallet, several buyer wallets and SOL moving between them – and every one of those wallets is a private key that can leak.
Regarding wallet security, here are the mistakes we see most often, and how to avoid them.
1. Reusing your main wallet as the dev wallet
The wallet that creates a token is public from the first second: anyone can see it on-chain, follow its history and link it to everything else you own. Use a fresh wallet for each launch, funded only with what that launch needs. Keep your long-term holdings somewhere that never touches a launch.
2. Pasting private keys into random tools
“Import your key to check your PnL” is one of the oldest drainer tricks. Before you paste a private key anywhere, ask who stores it, how, and whether you can take it back out. A key you pasted into an unknown website should be treated as compromised – move the funds and stop using it.
3. Keeping keys in plain text
A notes app, a Telegram “saved messages” chat, a screenshot in your camera roll: all of these end up synced to the cloud and are the first places malware looks. Store keys in a password manager or an encrypted file, and keep an offline backup of anything important.
4. Not knowing where your launch tool keeps your keys
Multi-wallet launch tools have to sign transactions for many wallets at once, so they generate and hold the keys for you. That is normal – but you should know how. Look for three things: keys stored encrypted, the ability to export any key at any time, and the ability to withdraw everything to your own wallet without asking anyone. SolBundle, for example, creates launch wallets for you, stores their private keys encrypted and lets you reveal and export any of them whenever you want – so you are never locked in.
5. Funding wallets with far more than they need
Every wallet in a launch needs its buy amount plus a small margin for fees and token accounts. Funding each one with “a bit extra, just in case” leaves SOL scattered across dozens of keys. Fund what the launch needs, and collect the leftovers back to one wallet when it’s done.
6. Forgetting about the wallets after the launch
Launch wallets often keep tokens and small SOL balances for weeks. Each one is still a key that can leak. After the launch, either consolidate balances to a wallet you control or export and back up the keys you intend to keep – and delete the rest only once they are empty.
7. Signing what you don’t understand
Phishing has moved from fake websites to fake transactions: a “claim” or “airdrop” button that actually approves a transfer of your tokens. Read what a wallet prompt is asking you to sign, and never connect your launch wallets to sites you found through DMs or replies.
A short checklist
- A fresh dev wallet for every launch.
- Keys stored encrypted, with an offline backup.
- Launch tools that let you export every key and withdraw everything.
- Wallets funded with what they need, not more.
- Leftovers collected after the launch.
- Nothing signed that you can’t explain.
The bottom line
Most losses around token launches aren’t sophisticated hacks – they are keys stored carelessly, tools nobody checked and wallets forgotten after the launch. A few habits close almost all of those doors, and they cost nothing.
