It's never fun to lose your valuable NFTs, and it's all too easy to click on stupid links when you're not feeling 100%, tired, baked, or whatever. It literally only takes one bad decision to drain your assets.
You should get a @Ledger. It will add extra steps, so you know exactly what is leaving your wallet and where it is going.
3/ But how to stay safe with a Web3 wallet like @MetaMask ?
This app will simulate transactions before Metamask is launched. The app's name is @PocketUniverseZ. It is a browser extension that keeps your assets safe when you sign #Web3 transactions.
Long before Ethereum existed, Meni Rosenfeld (@MeniRosenfeld) published a paper in 2012 that introduced the 'Colored Coins' concept for the #Bitcoin blockchain, which became the driving force behind NFTs.
2/ The idea of Colored Coins was to describe a class of methods for representing real-world assets on the blockchain in order to prove ownership of those assets; similar to Bitcoins, but with an added 'token' element that determines their use, making them segregated and unique.
3/ The limitations of #Bitcoin meant that the Colored Coins concept could never be realized, however, it did lay the foundation for the experiments that led to the invention of NFTs.
