CustosLab is for people who use crypto enough to know one bad click can be expensive.
DeFi Users
If you swap, stake, bridge, farm, or interact with smart contracts, you need better approval and signing habits.
Long-Term Holders
If you hold meaningful crypto, your wallet structure and seed phrase storage matter more than chasing the next tool.
Web3 Beginners
If you are still learning wallets, hardware wallets, DeFi, and approvals, CustosLab gives you a safer starting point.
Most Crypto Losses Start With a Simple Mistake
Most crypto losses do not happen because the blockchain breaks. They happen because users sign the wrong transaction, approve the wrong contract, trust the wrong link, or store secrets in the wrong place.
Malicious Approvals
Giving unlimited token approval to a malicious contract allows attackers to drain your wallet without additional consent.
Fake Airdrops
Scammers create fake airdrop sites that request wallet connections and approval signatures that steal funds.
Seed Phrase Leaks
Storing seed phrases digitally, in screenshots, cloud storage, or unencrypted files makes them vulnerable to theft.
Scam Websites
Phishing sites that mimic real DeFi platforms trick users into connecting wallets and signing malicious transactions.
Blind Signing
Approving transactions without understanding what you are signing can authorize unauthorized token transfers or drains.
Hot Wallet Overexposure
Keeping all crypto in a hot wallet connected to the internet exposes your entire portfolio to a single point of failure.
A Safer Way to Organize Your Crypto Wallets
CustosLab teaches a simple 3-wallet system designed to reduce the damage from one bad click.
Vault Wallet
For long-term holdings and larger balances. Rarely connects to websites. Ideally a hardware wallet or cold storage setup.
DeFi Wallet
For active trading, swaps, staking, and DeFi activity. Contains only the funds needed for regular use.
Burner Wallet
For risky mints, airdrops, unknown apps, testing, and low-balance interactions. If compromised, damage is limited.
