Navigating Web3 Securely: 10 Essential Steps

5 min

June 27, 2024

Web3, the exciting new frontier of the internet, is reshaping the way we engage with digital assets, data, and applications. Powered by groundbreaking blockchain technology and decentralized protocols, it ushers in a world where trustless transactions, computation, and data storage are the norm.

Imagine a digital universe where cryptocurrencies, non-fungible tokens (NFTs), and decentralized finance (DeFi) open up a treasure trove of opportunities. Here, you can dive into a global economy without the need for middlemen or central authorities. This isn’t just an evolution; it’s a revolution, making the digital realm more inclusive, empowering, and thrilling than ever before. Welcome to the world of Web3 – where your digital dreams can come true!

As we venture into this new digital frontier, we face an array of challenges and risks. Reports indicate a staggering rise in monetary losses due to hacks, surging from just under $1 billion in 2018 to a whopping $4 billion in 2022. The trend continues into 2024, with over $502 million lost in just the first quarter across 223 incidents. These alarming figures underscore the pressing need for robust security measures to safeguard the Web3 ecosystem.

These eye-opening statistics highlight the necessity for anyone diving into Web3 to take proactive steps for their safety.

This article outlines 10 practical steps to help you safeguard your assets while navigating the world of cryptocurrencies and NFTs.

1. Keep Your Private Keys Offline

Private keys are the cornerstone of your crypto assets. If they’re lost or stolen, your funds are gone forever. Securely back them up offline and never share them with anyone, no matter how trustworthy they seem.

Ways to Store Your Private Keys:

  • Memorize them
  • Write them on a piece of paper
  • Use storage devices like Cryptotag

Pro Tip: Never store private keys digitally.

2. Practice Self-Custody

At TransFi, we strongly advocate for self-custody of your assets. This means securely storing your crypto and NFTs in a non-custodial wallet, giving you complete control over your funds and private keys without third-party access. While it requires some technical know-how, it offers superior security and privacy.

Popular Self-Custody Wallets:

  • Hardware wallets like Ledger and Trezor
  • Desktop wallets such as Electrum and Atomic
  • Mobile wallets like MetaMask

3. Enable Two-Factor Authentication

Two-Factor Authentication (2FA) is crucial for securing your wallet and funds. It requires a code sent to your phone or email in addition to your login credentials, making it much harder for malicious actors to access your account. Enable 2FA on your wallets and exchanges, and consider multiple layers of 2FA for extra security.

4. Verify Smart Contracts Before Interacting

Smart contracts automate agreements on the blockchain, but some may contain malicious code. Use tools like Etherscan or Cyberscan to audit the code and check for vulnerabilities. Trusted services like Quantstamp can also verify smart contracts' integrity.

5. Use Reputable Services and Platforms

Always research the companies behind products and services to identify potential red flags. Verify website legitimacy by checking for HTTPS and a padlock icon in the URL bar, and only use trusted sites.

6. Read Transaction Messages Before Authorizing

When interacting with decentralized applications (dApps) or signing in with your crypto wallet, always read the transaction messages carefully. Unauthorized interactions can drain your funds if you grant malicious apps permission to act on your behalf.

7. Use Decentralized Identities

Decentralized Identifiers (DIDs) enhance security by allowing users to control their data without central authority. DIDs are cryptographically secure and immutable, making them resistant to identity theft and data tampering, thus protecting user privacy.

8. Be Mindful of Market Liquidity When Trading

Market liquidity affects how quickly you can buy or sell assets without impacting their price. Research the liquidity of an asset before trading, and consider using limit orders for better control over your transactions.

9. Always Have an Exit Strategy

Even if you’re confident in your investment, plan for potential risks. Set clear entry and exit points and create a plan for handling losses or market downturns. Remember, markets are unpredictable.

10.Set Slippage to Avoid Sandwich Attacks

Slippage is the difference between your requested and executed trade price. Set your slippage tolerance on decentralized exchanges (DEXs) to avoid sandwich attacks, where malicious traders manipulate prices. A slippage of 0.5-2% can protect you, but setting it too low might prevent your transaction from being fulfilled.


Venturing into Web3 can feel like navigating uncharted waters, but with these essential steps, you can safely explore the thrilling world of digital assets, secure payments, and decentralized finance. Stay informed, stay vigilant, and embrace the future of the internet with confidence. Welcome to Web3 – where your digital dreams are within reach!
