 types of wallets, hot wallets and cold wallets. So first I'll explain about the hot wallets, wherein it's always, you will find yourself always online. And in this, in these kind of wallets, you get your public keys, wherein private key stays with you. So in this whole concept of hot wallets, wherein you are always active online, you will be able to trade various kind of cryptocurrency NFTs. You can take examples of an exchange, wherein on an exchange, you just log in with your email IDs and stuff. And then you are able to access and buy and trade all of your cryptocurrencies and it will be stay native on that exchange. So basically your exchange allows you to interact and do the trading of the currencies. As the name suggests, it's a cold storage wherein it is not connected with internet. So in cold storage wallets, you have wallets like your USB type hardware wallets, wherein your entire private and public keys stays with you and it's not interacting with your internet. Once you want to make any transactions, you would have to move it to whole hot wallet. So once you sign in the transaction, then it interacts with the internet. And so it's considered to be way more safer than hot wallets, since it is not connected to internet and there are less chances of hacking it than having control of your assets. For accessing any metaverse, wherein we do and we go and do have a lot of interaction, wherein our avatars are going over there. Our avatars are walking, talking and once you move forward, you can see a lot of things around you which you can interact with. So all this kind of mathematical calculations and physics, everything is being controlled by your GPU. And the more we will be involved in the metaverse, it is going to allow us to try on different kind of possibilities, how this interaction can be more seamless, more easy and less sticky. So these kinds of things would come in place and I'm sure like the entire industry is working together in collaboration so that this metaverse concept which looks like a blessing to us can become a reality in sooner time. So at the end of the day, like whatever we are accessing, it's being rendered to us and this entire configuration happens on 3D engines. So like there are some good 3D engines which are like mass adopted by various projects. These are like either Unreal or Unity. So these are the two major used 3D engines. Now their capabilities and their use cases, it depends on like the kind of metaverse you are trying to build in, how hyper realistic it has to be. WebGL is being pretty decently used. Different kind of 3D engines using which you would be able to interact with the metaversical environment and the entire rendering of the piece and everything happens on that piece itself.
