Today I saw news reports saying that North Korean hackers stole $1.3 billion (worth of cryptocurrency) in 2024. Back in 2022, I was phished and lost 11 #ETH, which was almost all the tips I earned in my first year of tweeting. From that point on, I became more cautious about security, but security is not just about our vigilance; even tigers take naps, so both proactive and passive security measures need to be implemented simultaneously.

Proactive security means using multi-signature wallets and cold wallets to manage large assets, minimizing the funds in wallets used for transactions, dedicating specific phones and computers for wallet storage, disconnecting from the internet when not in use, and avoiding any operations other than transactions on the computer that holds the main wallet.

Passive security involves trying to use third-party security mechanisms, including antivirus software, which should be installed even on Mac computers. The most challenging aspect is for those who are after airdrops, especially various free NFTs, etc. Many people think they should take advantage of free opportunities, and some project teams use low-value NFTs to gain access to your wallet interactions. In the passive security mechanisms, MetaMask and Imtoken have already integrated some security scanning methods, but they are not yet perfect. @GoPlusSecurity is more specialized in the field of security.

Moreover, the main investors are Binance Labs and OKX Ventures. The on-chain security service supports over 30 public chains, including Ethereum, Solana, BNB Chain, Base, and Sui, which basically covers the needs of most users. For those with a lot of interactions across multiple small wallets, it might be a useful tool.
