Security, Trust, & Troubleshooting

Is Nansen Wallet safe?

Nansen Wallet is non-custodial. Powered by Privy, a trusted brand in the crypto space.

What that means:

• You control your keys (we never access them)

• Powered by Privy’s secure infrastructure

• Two-factor authentication required

• We don't custody your funds

You're in full control. The wallet just makes execution seamless within Nansen. Think of it like using MetaMask, but integrated so you don't have to switch apps.

What if Nansen gets hacked?

We can't access your keys. They're encrypted and stored using Privy’s infrastructure (the same security model as MetaMask). Even if Nansen were to get hacked, keys won’t be accessible due to MFA (if you have it enabled).

Even if our servers were compromised, attackers couldn't access your wallet keys. You'd need to compromise Privy’s infrastructure separately, which uses industry-standard security practices.

That said, security is always a shared responsibility:

• Enable 2FA (required)

• Don't share your credentials

• Review transaction details before confirming

• Withdraw to cold storage if holding long-term

Can I use my existing MetaMask/Phantom wallet instead?

Not for trading right now. Trading uses Nansen Wallet for the seamless experience:

• There will be gas fees on Ethereum but not Base or Solana, only if you dont have the native token.

• Instant setup across web and mobile

• Automatic syncing

But you don't need to move all your funds. Just send what you want to trade.

Portfolio tracking works with any wallet—MetaMask, Phantom, Ledger, whatever. You can track your full holdings without moving anything.

We're logging requests for external wallet support for trading. If enough users want it, we'll consider adding external wallet integration.

What happens to my funds if I lose access to my Nansen account?

Your funds are stored onchain in your embedded wallet, so they don’t disappear if you lose access to your Nansen account.

If you can’t log in, start with standard account recovery (e.g. email/password reset). In some cases, additional verification may be required to restore access safely.

My transaction is stuck. What do I do?

On EVM chains:

1. Check network status (etherscan.io or equivalent)

2. If network is congested, it may just take longer (up to 30 minutes during high traffic)

3. If stuck >30 minutes, contact support with transaction hash

On Solana:

• Transactions either confirm or fail quickly (no 'stuck' state)

• If failed, error message explains why

Don't submit another transaction while one is pending- it can cause conflicts.

I got an error: 'Insufficient liquidity.' What does that mean?

The DEX pools don't have enough tokens to complete your trade at the quoted price.

Solutions:

1. Reduce trade size (try 50% of intended amount)

2. Increase slippage tolerance (allows more price movement)

3. Wait for more liquidity (check back in a few hours)

Low-cap tokens often have liquidity issues. Stick to higher-volume tokens for large trades.
