 Here you are, Lige. Yes. Welcome, welcome everyone. And as Maurice said, it's actually a good thing that we are not so many people. So we can have more hands on and more discussion in the end. Because we want to also, it's not about only what's new in Wallace. I also want to show you this thing and have a hands on here basically. So we use Wallet Connect to open the box and then you can get drink vouchers. And as you are so few people, the chances are higher. And we also like have status IM hardware wallets in there. So basically after you open the box with Wallet Connect, it looks like that. There are your vouchers, some stickers, and on the left the hardware wallets. It would be super awesome if the hardware wallets only get taken by people that actually have an Android phone with NFC support that it can really be used. Because currently they are quite expensive but they get cheap. So it doesn't really make sense to just collect them and they get dust. Please really test with that. So you can take one if you open it, but really then also test around with that. So now a little bit, what's new in Wallace? One thing that really really changed is the account management. Before, I thought it's a really good idea to just create an account in the beginning that you can just get started. So you start the app, you have an account ready and you can do things. Basically that was not the best idea because it depends on the use case how you want to use your wallet. Not all want to use it with a burner wallet. Some want to use it with different accounts, for example with the Trezor. So now when you start the app, you can select your use case, concentrate it on what kind of account you want to start. Like the first, as the burner basically, I took this name from Austin Griffith. Just Austin Griffith current is wonderful term of a burner wallet so everyone knows what's going on there. That was actually how it worked in Wallace before. Like I didn't have a password because I think that's easily to get started is the thing, so it was a burner wallet but I was never calling it that. But the name is really good and now also like distributed in the whole ecosystem. So that's now called that. The second thing, and I think you basically should go usually from a burner to a Trezor. So there is I think nothing much in between. We have more stuff in between but I think that's the way to go because if you then really have an account that is worth something. You want to protect, you should protect it with a hardware wallet and that's connected via USB OTG. Now with the Model T with USB-C it got really easy because before it was a bit fiddly you had to have this OTG adapter and put it in the right direction but now with USB-C connected to the phone that's really easy. And it's also updated to the recent Trezor. That's also a little bit of a drawback. I couldn't get backward compatibility without a lot of overhead. So I'm just now like well it's just compatible with the latest version so you really have to update but that's also how a Satoshi Labs does it internally. They really want you to update and then force you basically to do that. I was looking into backward compatibility but the problem is like it's a protobuf and it would increase the app size a lot and I'm really caring about the app size and I didn't really want to do that. The next thing is for example if you switch your phone it's import key so you export it on the old device you import the new one you also don't want to create a new account you just start the app, you import it. The next thing if you don't even want to have keys on there is watch only so you just specify an address or scan it and then you can just watch it so some people just don't trust their phone but if you just want to watch if you get something incoming you can only use that for that. The next thing is NFC and that's also very very new that's basically about these key cards which are also like in the box. They are really new and wallet is the first wallet that supports the key card now it doesn't yet support all features currently you can make transactions and set up the wallet make transactions and that's basically first of all it but it's a good thing to start there are way more features that this key card can like what's really interesting is the pinless derivation paths basically so you can pay it post systems and imagine it like the mixer recently also came up so imagine like a mixer that always fills up your latest pinless derivation path and you just pay with it in a private manner that opens a lot of possibility and also like in the mobile case what you would use case is copying of these cards because that's really probably you want to copy these cards without exposing the key to the device that's copying if you want to do a direct copy unfortunately you can't direct copy the cards but the key card team basically invented a system with multiple wallets you have basically witnesses in between that nobody sees the whole key but you can still transfer the key from one card to the other for backups I think that opens up a lot of possibilities but it's quite new and I want people to actually try that out the advantage is to a real hardware wallet is like you don't have to plug it in it's NFC basically you just tap so you tap on your phone and then basically your transaction is done or got signed and then it's done when it's sent somewhere so you don't have to plug in some USB it's a bit more convenient that way and it's also way cheaper but what you see like the big disadvantage of course of that is that you don't yet have displays on that so it's a bit less secure but you have the trade-offs but it's a good trade-off for a lot of use cases that's how it looks basically then you either have to select you want to do a new card or you haven't already initialized card unfortunately currently you need to like basically when you have a new card remember three things it's like a pin six digits a book 12 digits and a pairing password for the daily usage you just need the pin if you forget your pin and the pairing password you need that if you want to pair with a different device basically so in day-to-day usage you just really care for the pin and then basically after you press that it has you like to bring the NFC tag close to your phone sensor and action and then it's basically the same as always that's another thing like people asked just for pin protection I think really you should go from a burner to a hardware wallet but some people asked for that I don't really know why because I think then the protection of your pin or the protection from your phone is basically you should only use that when you like do 20 euros like pay for drinks or something like that it shouldn't be high value and then the obstacle of having to remember a pin is higher and the security gain is not that much in the end but people asked for it very loudly so I added it and you can now protect it basically and also you see that's an internal keypad because also people asked for passwords that's even more rudimentary because I also think because here you share the keyboard basically these keyboards are external services you share your password with Google and that's a problem so rather I think use pin but some people asked for passwords you can now also do password protected accounts what also a lot of people don't find is basically the shortcuts because what you really often want to do is just scan something and with Android you have these wonderful shortcuts so you basically just long press on the walls icon and then you have scan and chance act if you need other shortcuts let me know but these are the use cases I know especially scan for example if you want to use it with the box just get the scan you don't have to go into the app and then select scan deep in there you just shortcut scan, scan the QR code and you have your use case ready in the end this is the new account listing basically that also has a little bit changed basically when you want to manage a lot of accounts in the end then you want to basically start some accounts that you really use often you want to just select the ones with the key or just basic filtering and you also like the indicators you're on the top right you see basically you don't see my cursor here basically these are watch only accounts there's a burner account pin so the images are used always that you recognize from creation to right there and if you're everything that is basically this greenish color you can press for example like on the burner then you export your key so that's your key export then these are the networks there's also like a lot of more new networks now supported basically everything that's an Ethereum list change you see this different symbols here, Goalie for example has this lightning and that means you have really really fast access to a thousand just one click and you basically auto your current address is auto filled and it's just basically one click to fill your account some like rinkabee where it's just like this present thing it's a bit more complicated because you have to do this tweet thing and that's a bit more cumbersome I can't just invoke that from the app that easily so basically you can still go to the folder but it's a bit more manual process it's not really that fast so I also start with Goalie because it's basically just you open create a burner give me money and then you have your money and you can spend it and try things out in the end and also now with the Goalie pusher you also automatically get pushed to token so you can transact token transact ether and can try the different stuff with that these are basically all the networks then supported in the end it's all a chain ID network and if you want to add some networks just add them with a pull request to Ethereum list chains and then basically you can press the sync button on the top right and then the new chain is also added yeah that's it that's the new tokens tokens basically the same like Goalie the root token then also has this faucet link and you have standard tokens and I think over a thousand of them and those are collected in Ethereum list tokens so if you want to submit your own you can submit them there that sounds a bit stupid like you just change a toolbar but it's also like a security implication because when you make the wallet your own you basically recognize clones or recognize fakes that just pop up but they might not know the color of your wallet so you're especially warned before and I want to do that a little bit more because I want to show you what you can do so you have some just otherwise it's quite easy to make a fake app that just pops up and you put your credentials and it makes something malicious you have also this security information now it basically gives you your latest patch day but it's only important if you really hold a key on the phone so if you use it with a treasure that your latest patch of your system not of the app but your latest system patch not so long ago you have to see routing because routing would break the app isolation also warns if the phone is rooted that will also not be good checks for lock screen and different other stuff yeah now I want to talk a little bit about what was added and now I want to talk also like this is the thing perhaps people have read the blog post recently of the Ethereum foundation like subtraction is a really beautiful concept and I also removed stuff from all it not only screens like before I was also removing screens that just de-duplicated but one thing is a bit first a bad thing I moved away from the light lines because they just provided so bad user experience like the default there is still a flavor for light lines but the default is now not anymore I want to move to RPC I want to move to Incubed it should come in Q2 like I got the deadline Q2 and then basically the minimal verification I think it's a much better user experience in the end and you still don't have the centralization problem let's see when it comes out it might be quite easy because it's also RPC based flavor I had it in before because also WalletConnect in the beginning had Firebase so I had it added and I had it as a flavor because I needed to put it out anyway for Afteroid so it was not working on Afteroid so I had two flavors like one with Firebase for Afteroid and one with Firebase for Google Play but I now completely removed it because it's not used for WalletConnect anymore and it also really helped the direction of making the app build reproducible and Firebase was a problem there alongside a lot of other things so I now just did a step to remove it and also it helps new developers because Firebase also have the secrets and then I had to have a Git crypt in there and hide these secrets so now there's no more secret and there was a problem before for people that just try to build the app clone it, try to build it but then you rely on the secrets to work so it's now completely removed subtraction following yeah a bit in the reproducibility I had it already recently building reproducible unfortunately now there's a new bug where just one bit is different yeah in the but we figured it out so that's only forefront there is a new field but I think that can really help in the future because there's also a problem how do you like you know this app is open source but how do you know that the binary get belongs to the source you've seen and that can really help so we can really then spread out different people build the app and agree on the hash form the release hash for the comment hash and then you can really trust this app way more and there were also like some organizational changes everything was grown in the beginning in the Wally's organization but there was this library key theorem that was growing in Wally's but now matured into a new organization called computing because there's also people that the advantage of having everything there in Kotlin is you can not only compile it to Java and use it for Android for example but you can also use it to compile it to JavaScript and have like basically static typing with JavaScript but I didn't want to have it because it was then exploding also like in kithium split in different modules to have it easier and it was just growing in the so it's better to split the organization there and have a bit of separation of concerns yeah now a little bit bullet connect also updates like to the new standard you can also like try it out here we have some things to try it out later on also Pedro will talk a bit deeper for sure about Wally connect about that afterwards but he's basically changes like the new standard also make it visually a bit more pleasing please try it out and now we also see that the adoption gets by higher like now Metamask is on the train so we get traction and we need more dApps now to try it out like this is also one dApp and Pedro shows a dApp let's do more dApps and really try it out because I think that's a beautiful concept basically to separate wallets from the dApps yeah that's for me basically if there are any questions otherwise Pedro will go directly with wallet connect yeah thank you all questions it's minimal verification clients basically so it's a smart contract where you can register as a provider of data and then you have a stake there and then you basically sign all the blockages you like on request and you can lose your stake if you signed the wrong blockages or like so I can trust the data regarding to the stake basically also depends like sometimes like if I pay my coffee I don't need the millions of steak because it's just about the coffee so then it's also like can somebody with small equipment basically do it yeah but just it's a project from Slocut basically and they did talks also about that unfortunately it's not like the servers yet to release so you can do the server part already but the client part I need especially the C++ one is not yet done but they said like Q2 and Q2 is basically a month or something like that so it should be but I think it's a nice solution because the thing is with light clients it sounds light but it's still heavy you know you still have to have this peer-to-peer chatter you still have to download a lot of data it's less than a full note but it's still a lot of data in the end and then if you see you don't only have one chain you have basically multiple chains you do that for everyone and let's say main chain was now 50 megabytes but then you have different chains and always have this also this weighting of until it's zoomed and that's for users is really bad you have to wait until it's zoomed your phone gets fucking hot, your battery is empty users are just angry and it doesn't have anyone it's the right thing to do usually that's also like I was really struggling to remove it basically it's not removed it's just basically not the main thing it's still a flavor you can build it and use it but the main thing is now the APK size got much smaller and I want to target emerging markets and they don't have the newest phones or data lines it's really important that the APK size is also small it has so much advantages the traffic is way less traffic also we have allowances of gigabytes it's like every megabyte counts and the like line is really like it's sucking data it's like basically you just do in the end you simplify and it proves with that and then yeah so here's the follow up what do you have a proof of is basically the latest head of the blockchain right the block hash yeah you have a signed block hash basically and from that you can go back and prove your but it's basically I'm an application developer so watch the talks from Slocut about that and yeah I don't want to go too deep into that because I basically just leverage that and that sounds like a good solution but scrutinize it if you're really into that really scrutinize before I put it in they put out it's a white paper out read the white paper yeah and then yeah other questions yeah you mentioned that you're not using the like client anymore but also not the in-cube stuff yet so what do you use in between RPC like basically everyone is doing it's just now basically you use RPC it's not good but basically everyone is doing it it sounds bad like everyone drama's out of the window and you jump afterwards and I really struggle to do that but the thing is also like for a lot of users strangely it doesn't really matter they just use it and they compare the user experience then they say you're wallet and getting your phone hot consuming all your data and still doesn't work sometimes because like clients also sometimes it just fails for some like yeah and just a horrible user experience and people just say yeah your app is bad okay and the thing is also like with these systems you can also make it more gradual you can also like basically have a trust slider in the end you might be okay with starting like with minimal trust you know just trying things out and then things get more serious and then you increase the trust slider and that will also in the end cost you money and there's also no thing also with light clients it will cost money in the end it's just not sustainable you know currently there are some like but you also see when there's a spike then the light clients servers are also you know that doesn't scale and there's now like there's this project basically rent light client servers but you also see with different nodes it's really good what they are doing but there's still a problem like phones still gets hot but at least you get a light client slot but imagine you don't get any slot so yeah it's a big mess but does it answer your question cool other questions no more questions okay thank you so much for all this great news and information
