Despite the growing maturity of DeFi, losses from human error or security breaches continue to amount to billions. In 2024 alone, billions of dollars were lost due to bugs, scams, or simple negligence. In this context, understanding the most common mistakes is essential for every user.
Ago, as a non-custodial DeFi project, is actively working to strengthen user protection.
Private keys: no return access
The core concept of DeFi is sovereignty. But with freedom comes great responsibility. Losing or having your private key (or seed phrase) stolen means permanent loss of your funds. Many users still fall into simple traps: saving it on Google Drive, screenshots stored on a phone, or sharing it with a “trusted” third party.
Best practices:
• Always write down your recovery phrase on paper or a secure physical medium.
• Never share it — not even with someone claiming to be “technical support”.
• Use a hardware wallet (Ledger, Trezor) for significant holdings.
Unlimited approvals: a permanent open door
When interacting with a DeFi dApp, it often asks for “approval” to move your tokens. Many users give unlimited approvals, which allows a contract — if compromised — to drain your wallet at any time. It’s one of the most exploited vulnerabilities by hackers.
Best practices:
• Always check the contracts you’re granting access to.
• Prefer limited token amounts when approving.
• Use tools like Revoke.cash or explorers (Etherscan, BscScan) to regularly revoke unused permissions.
Phishing on Telegram or Discord: the most common attack
Fake admins, fake airdrops, bot-generated support messages — scams via messaging platforms remain widespread. A single connection to a fake website can be enough to sign a malicious transaction.
Best practices:
• No real admin will ever DM you first.
• Never click unverified links.
• Always enable 2FA (two-factor authentication) on every platform.
Quick checklist before interacting with DeFi
| 🔒 Action | ✅ Why It Matters |
|---|---|
| Seed phrase stored offline | Prevents remote hacks |
| URL verification | Protects against fake sites |
| Limited approvals | Reduces risk in case of attack |
| Monthly revocation of rights | Regular cleanup of permissions |
| Use of cold wallet | Long-term fund security |
What Ago implements
As a non-custodial DeFi platform, AGO takes a proactive approach:
• No custody: AGO never holds your funds. You stay in control of your keys at all times.
• Secured approvals: All staking, swap, and trading contracts limit permissions to avoid critical errors.
• Audited smart contracts: All AGO contracts are audited before going live.
• Ongoing education: AGO regularly educates its community through blog posts, Telegram, and FAQs.
• Responsive support: Help is available via email and Telegram to guide users in case of doubt or issues.
Conclusion
DeFi is not inherently dangerous — bad habits are. Exposed keys, overly broad approvals, reckless clicks: by adopting a few simple reflexes, users can effectively protect their assets.
At AGO, security remains an absolute priority. We support user autonomy without compromising on transparency or accessibility.
