Non-custodial wallets & general crypto safety
What is a non-custodial wallet?
A non-custodial wallet is a crypto wallet where you control your private keys and seed phrase.
Important: No company, exchange, or support team can recover your funds if something goes wrong. Security is 100% your responsibility.
Most common crypto scams
Seed phrase & private key scams
Scammers try to obtain your seed phrase or private key by pretending to be support, admins, or “security teams”.
Never share your seed phrase or private key with anyone.
Phishing & fake wallets
Fake websites, cloned dApps, and malicious wallet apps look almost identical to real ones.
Protection:
Use only official websites and app stores
Bookmark trusted links
Double-check URLs before connecting your wallet
Malicious smart contract approvals
You may unknowingly approve unlimited access to your tokens.
Protection:
Read transaction details carefully
Avoid unlimited approvals
Revoke unused permissions regularly
Fake airdrops & “Free token” scams
Unexpected tokens or messages asking you to “claim rewards” are a common trap.
Red flags:
Urgency (“limited time”)
No official announcement
Forced wallet connection
Impersonation & support scams
Fake admins or influencers contact users directly.
🚫 Legitimate projects never DM first and never ask for wallet access.
Investment & social engineering scams
“Guaranteed profits”, trading bots, insider tips, or romantic trust-building are all classic scam patterns.
There are no guaranteed profits in crypto.
Critical safety rules
Always verify the recipient address
Before sending crypto:
Manually verify the recipient address
Compare first and last 4–6 characters
Do not rely on copied addresses without checking
Watch out for clipboard hijacking malware
When possible, send a small test transaction first
⚠️ Once a transaction is sent to the wrong address, it cannot be reversed.
Do NOT share your wallet address in public groups
Posting your crypto address publicly can make you a target.
Risks include:
Targeted phishing attacks
Dusting attacks
Address poisoning
Social engineering attempts
Tracking of your balances and activity
Best practice:
Share addresses only in private, trusted conversations
Use different wallets for public activity and personal storage
Generate new addresses when possible
General best practices
✅ DO:
Store your seed phrase offline
Use a hardware wallet for large amounts
Separate main funds from interaction wallets
Verify contract addresses from official sources
Keep devices clean and updated
❌ DON’T:
Rush transactions
Click random crypto links
Trust screenshots as proof
Connect your main wallet to unknown dApps
Believe in “double your crypto” offers
If you suspect a scam
Move remaining funds to a new wallet immediately
Revoke all approvals
Stop using the compromised wallet
Warn others if appropriate
Keep your funds safe!
