🔐 #Web3SecurityTips: SecureWeb3 Checklist 🌐
Most of the fund losses happen because of violating best practices and basic security hygiene while working with web3. In the case of protocols - that is what audits are for. Auditors will always notice such violations together with vulnerabilities and provide the appropriate recommendations to fix the misbehavior.
But in the case of user safety - there is always a need to remind the basic hygiene, so they will not be left vulnerable and "un-audited".
1️⃣ Never transfer ERC20 tokens directly to the contract, unless you are 100% sure that is the right user flow for the protocol. In most cases, contracts do not have a "rescue" function and your funds will effectively become stuck.
2️⃣ Always read available documentation of the protocol to use the appropriate interface to deposit funds. Make sure you know how the protocol works and your position will not be liquidated immediately.
3️⃣ Double-Check what amount you are going to sign or approve and make sure your wallet shows it to you. UI may be misleading and the actual amount may differ from the one in the interface.
4️⃣ Always recheck if the website you are interacting with is the correct one:
- check misspells in the site name to avoid mimicking malicious clones;
- always check the news from the protocol you interact with to see if it was not compromised.
5️⃣ Double recheck the account/protocol addresses you are going to interact with - symbol by symbol. User can be easily tricked with the spoofing address mimicking the actual one
6️⃣ Always check the result of the transaction - that it is successful, and that the balance was changed. There are enough flaws in ERC20 to mimic a successful transaction, so always check the balance
7️⃣ If the dApp allows, use the features offered by ERC-1363 (Payable token), or ERC-2612 (Permit)
Stay vigilant, stay secure! 🔒 #Web3Security #CryptoSafety #BlaizeSecurity
🔐 #Web3SecurityTips: ERC20 Risks & Best Practices 🪙
ERC20 is a standard adopted in web3 nowadays. It introduced an approve-transfer pattern which is ubiquitous in modern dApps. Since it is almost impossible to replace ERC20, you should know its main flaws and be aware of the basic hygiene of token usage.
🚩 The gap between the approval and transfer means that you cannot be sure when the spender will transfer your funds.
🚩 Such a pattern leads to a lot of "dangling" approves - unspent amounts just open with no outdated.
🚩Since sometimes it is hard to calculate the exact deposit amounts, dApps try to force you to approve more than needed.
🚩 Some dApps like Uniswap force you to perform "infinite" approval.
Such behavior increases the risk of funds loss. So, make sure you follow the best practices:
1️⃣ Always check that you don't have "dangling" approves. Use revoked cash to facilitate unrevoked approves.
2️⃣ Adopt the best practice of safe transfers: either approve the exact amount to be transferred or send the approved (0) transaction just after the transfer.
3️⃣ Use wallets that clearly show you the amount to approve and spender.
4️⃣ Always check what approved transaction is constructed by the dApp - don't trust UI blindly.
5️⃣ Avoid "infinite" approvals at any cost.
6️⃣ Consider using tokens with the support of ERC-1363 to utilize the approveAndCall callback.
Always review your transactions, especially when dealing with ERC20 approvals for untrusted dApps. Stay safe in the DeFi environment with https://t.co/i6B6QbykR9! 💻🔒 https://t.co/Z9n7dELiSn

🚨#Web3SecurityTips: New Hackers’ Method for BNB Smart Chain! 🚨
Recently cyber fraudsters have found a new way to exploit BSC (BNB Smart Chain) smart contracts, using them as hidden repositories to disperse malware. Let’s have a closer look at the case and try to make proper conclusions.
🔍 What's Going On?
📌Attackers are compromising WordPress sites and embedding code that fetches malicious payloads from blockchain contracts.
📌These BSC smart contracts act as anonymous and cost-free hosting platforms for the hackers.
📌Disguised browser updates. Victims, thinking it's just a routine update, are lured to fake landing pages, leading to entire site takeovers.
🔄 What Is the Threat?
📌Malicious actors can alter their strategy by merely updating the harmful code in each blockchain transaction.
📌Once these tainted smart contracts are active, they run on their own, leaving platforms like Binance dependent on their developer communities to spot and report the malicious code.
💡 Stay Vigilant! Always be cautious, double-check your sources, and avoid unfamiliar browser updates. The web3 realm is full of opportunities, but also threats. Never forget: safety first! 🛡️

The #blockchain gaming landscape is evolving at lightning speed - closer and closer to F2P gaming🎮So the required #security level becomes closer and closer to cybersecurity standards. Let's take a closer look at #Web3SecurityTips for the topic together!
🚨Account as #NFT. New trend which brings more utility for NFT and ownership - and more threats for the user. Number of NFTs stolen grows rapidly - so despite extreme convenience, now you can lose not 1 asset, but the whole account.
🛑Also, in-game assets are still NFTs - so regular #web3 #security rules must be strictly followed. More about the recommendations for NFT hygien by Blaize here: https://t.co/NrMS8Y2a18
🛠️ The newest games separate gameplay from #blockchain, with many operations now left off-chain. Remember: what is offchain - can be stolen or manipuilated easily. Secure oracles are crucial to prevent manipulations - especially with NFT prices. Rely only on trusted data feeds.
🟢Growing in-game socializing is another trend in #blockchain gaming. But it leads to increased awareness against social engineering. So check emails and chats for phishing - and be ready to attempts of stealing your emails and payment info though crypto-related channels.
#Blockchain games still possess #play2earn elements - which means tokens utilization. So be aware of basic info hygiene - check links, mails and chats carefully to avoid phishing for your private keys and untrusted sources🔓
❕In-game reward tokens are just like any tokens - be careful as staking contracts are the first target for hackers. So enable #defi #security rules by default: do not perfom approves for untrusted dApps, do not accept suspicious tokens, avoid lotteris and drops
Instead of conclusion: Modern #web3 games need top-tier overall #security, just like #defi protocols or bridges. Remember the Ronin network and Aavegotchi hack? Stay vigilant!🚨 And remember: safety first!
