Exit 28. Esteban, u.s. Consensus. You want to give the orders to quick background about yourself? So, I joined the abduction space in 2018 and I went to Berkeley. I was there in, like a lie, then after that, I got an intern in May 2018, and I start work extension, on the Celtics, starting to explore their molar. Then I joined full time to start working out. Essence mix by now, working full-time and moral right now, working on sucks for more great. You see if Cher Cher

born at the bottom? When you see my screen. No. Mega awesome. Alright, so yeah, I'm going to show you what we've done in the related to. This was released in October last year on the station. This is talk to greet one problem that we wanted to stop and not the West. Finding a swap it to, it's a problem with for new users. And because I think the first one is dead, their entry, the barrier until we have many protocols in the device space. So for new users,

they have to take a look at each of those or guess just one but they're going to lose some other things that you see want for example, pay rates that they're going to get from from the different portal. It's going to be different to. So they could be spending more gas than one for the gold than others. If they want to do big stops, and maybe there's an option to fragment the swap into different protocols, to to get a better quote and also for your seat when you took and slaps me to

a waltz and yes, the 22nd of four walls for each fret about that you are interacting, with which can be expensive and messy for uses. So this was if your if you swear you smell of musk and they will go to different, protocols units have killed every day whether or not they're going to get different place and they're going to get different liquidity. They're going to have to approve on its protocol and they want to do so, I don't know that they're going to get different species.

So, I can look through your nice off day. Then only one another 101 and potentially many more in the future. So for new users, if we want to onboard juices that are not technically experienced enough to know about this. This is going to be overwhelming and we want to, we wanted to provide a way for users to do this in a few steps. So we sent you on the extension. So we're going to provide a better place across Define in in one place in one. Standard music, please. So that way we

did, that was Tim in qualifying with those guys are building this API on Smart contract. That interacts with the air with the disciples. So we are going to relax with the API and smart contracts, which interact with disposable without the user knowing what's going on. So we will remove the fusion of users going to each of those brother goes by going to minimum interact with the Khalifa smart contract through metamask doing this job. They want In this way, we we

provide users with the best quotes that are going to give them in the best grade. They can get from the the difference if they want to large shrubs. And we, we may want to spread this up between different Texas, interacting with metal mask, is going to Meadow Sox, is going to just need one approval, Jersey, 22, guns. So, if you want to stop by too, with whatever you're just going to have to send one, I brought in section. We are going to give you the most efficient type in terms of the gas.

So that that's going to understand which is really important. Today sucks. What are your most most excited to share with you? And she said the work that we've been doing on the Moor type and This couple of months and this is something that I've been working on it with the team. And we want to release very soon. So I have to show you how it's going to work. So you were going to be able to stop from there. So you have either and you're going to have, you want to select the talking to us up at 2

and you just click and get quotes or interact with the qualifying API and it's more contact to get the best quotes that you can do with the straight. So, we get the quotes, you can view all the quotes. And compared those and see the details. Do you want to know more? What is going on behind the Yep. Uncomn compare that devalues anything and you just do swipe to Swap and there's going to be nothing else more near from the Eucerin. Knudsen, and into your steps and you're going to get to

To the shop and they're going to get their their tummies. So right. I also spoke about during your C 20 tokens flops, which in this case is in this demo and Link song are two anything you want. So you're going to get Let's wait for that part again. If you want to stop to UniFirst sample and you, this is the first time that you interact with the feature, you're going to get an inspection before the actual trade. So you can see there is a descendant extension house right now, and you can or not, you're going to be able to sleep to see the

Colts before to compare those. What what is going on? I just swiped the swap. So in three steps animal. You're going to get to to do swaps and ask him this way lyrics. Do you think they're going to get the subs? You want it? Saudi Twitter is currently in development. You want to it's going to be going in a few weeks. So we are extremely excited to put this picture. I'll swing by the grocery outlet in the mall. Right front. We have a new users that are not very experienced with it. If I put the bulbs

so it could be there for them. Go to the to the extension and swap in a specific protocol to a browser and go shopping and specific protocol. Underground. They are going to be able to eat from them from the app extension and just three steps. So this is dr. We wanted to get a better device. Bring them to an experienced serious day. Preaching that interact with different protocol Sky release. We wanted to get a few of peace and bit earlier value to the users. And in the same way doing a building, a sustainable and ethical business model

Camaros, and this is how is going right now, so we just crossed a billion dollars in detention. With the release of medical swap. Small breeds baked and 1/2 to attract more users to eat. And do they have you tried? That's not very well. We have over 130 unique accounts to Wingstop's so far since October. So, if you want to download the app for go to extension, you're going to Discount Liquor code. That's going to send you today. We have stores. Keep waiting for the subsidized. Going to be in the mall. I have a

threesome. What's the percentage? Using the metal mask tool and that is to do any transaction. So we we have a viable piece that goes up to 0.875% and less efficient. Four different. Protocols. There is a different fee on the important part is that you can see the fear that we are charging on H quotes and 2222. Gotcha. So how many how many protocols now does the app request for quote? So far, I believe that we have steaks, but I could be mistaken. So, do you have any idea what was going

to the decision to add another protocol to that request? Yeah, right was right now. We are of course looking into different solutions to get fewer fees. So that is one important thing that we are looking for. So interasian of the year to see, going to be something that we we are looking into it right now. So we're related to all the new abilities and extension to our networks to interact with Laird to Solutions something that we want to. We want to go so it sucks. How about security?

Is there a security liar? Normally, I know one on the desktop browser is Chrome Chrome extension. You can use your Hardware wallet to sign transactions. Another mask. Is there anything how to security work without a mobile phone with the mobile app? Yeah, and we don't we don't bring keys for cover, while it's under Imola Bridge. Everything is starting to register system for Android and iOS, so, We we are looking to, I really wanted to shinsei for the, for the up to, but right now we are just leaving the security of the Russia

anymore questions. Feel free to ask me if someone wants to switch, to something besides in feura. Is that possible? Another words fit for one? It's my own etherium node VR PC remote procedure. Call Ben Reed mobile on extension you, yes. Want to go to settings. I believe there is a section called networks. There, you can go to to add Network and you can have their like the kitchen tidy, the name of the network, the IPC and point, you're going to be able to go out.

And also this week, are we really stand extension side, then you mention id'd. The allows us to propose a new customer Network. So they're going to be able to tell the user. Hey, we work in this in this, a PC Network and they're going to be able to interact with whatever. Hey, brother, what they want. Any other questions out there? 7, other one. Is it possible to automate trades or schedule swaps or anything like that with with metamask? Is no grain out of a couple

things to look into. What, what, what do you say start looking about? I mean, it depends, if you know, certain. Of time if I wanted to swap out, if you know, when I sent to another, you know, just kind of set forward to schedule for doing stuff like that or if I have a bunch of wbtc and I want a scale in scale myself into another, another product that you want to set a schedule to swap into it moves schedule, trade some. In time right now, but maybe something interesting to look into it was really nice. You know, I think this first step is a big step

where you're Gathering up all these quotes and I'm getting it to the mobile. Are there any other? Any other Define aspects that the men of this team is working on a side from the swaps? So, they need a new picture that I mentioned before is going to work. If each one is going to allow any layer, 2 solution to work with me tomorrow. So if you are in a In adopt the trucks with an F-22, released to work with that, you're going to be able to relax something. Women looking

into like for a very long time. There are people from the team working on that VIP. For three years. I think one year 2 years. So that is something that I think that is going to grow. It's going to be it's going to be able to scale to defy protocol Starfire in alert change, but allow me to remain. So that's something I pulled all together. So tell me about your team. Can you describe, you know, how big the team is where you guys work? No, is there a fork over there? A centralized office after is everyone? Will you be a fully remote team? What's the makeup of the team? We've been always remote

night when I was doing my internship. I was remote. So I've been all my life in a remote and right now and the things. Distributed around time, for some flying in Santiago Chile in South America. We have people from United States from Europe. From do I go from Delhi? No, sorry. Asia. I forgot that it would be encouraging with a very talented team from qualify. And the person that did the team does work on the API and they're smart contracts. Those guys are I appreciate the concern and breathing and you sex all the time.

Sure, seems like you got a lot going on. It's fun to be here. Yeah. Seems that way Louis asks some while it's have tokens. Is there any plan on token issuing from metamask? Gotcha about analytics data for the transaction. Analytics. Is does metamask have any tea or Bitter. You push out the window, will start in the swallows and like in Port in water or creating a new wallet from the extension. And also you are asked to to updating or opt-out to her and that we are just doing that to to provide a better.

You extend it for the inducers people want to opt out, that's totally fine. And if you often we are just checking. You're using the the extension on the app. Not nothing about your ass and nothing about your transaction activity. So so collecting the transaction info is that info available publicly? No, wait, we don't tract infections. The only thing that is pollock, is the June that I show you in the presentation. That is just introductions to Smart contract that we have. But India, if we don't track anything at all about your salary, some personal information on a

Man 3 years. So what's the most have you been working on metal mask the entire time or you been on other projects? No one knowing nothing turn on you. And then I'll drink for time. I was working since day one of Mall, almost 3 years ago, so, We released mobile and July last year. So I was working a mobile before the release for two years and then Eight months ago. We replaced the app of my. What would you say is the most surprising thing? That's you've come across working on metamask in the last year. I would say, do you want? Stay

the same like everything moves. So fast in the ATM. If you want to be, do you want to be up, too? Late to everything is almost impossible because so many things are happening in this at the same time. So that is that is something that I also like allowed because It's a push you too to be learning new stuff, everyday. Something very nice environment. Yeah, it's always you always pushed. You always always. It's learner. I almost. It's a fun place to be.

Did any other questions from the audience? Nothing right now? Let's say, I wanted to ask you something. It's just it just passed my mind. How big is the team over there? It's working on that masks, the whole Middle East about. 2530. I will say we are growing into. Yeah, yeah. Yeah, we've been growing. And we want to roll my mower. So we are, we have open positions to hire right now. So if anyone listening 12 wants to to go to meadowside, go to the careers site and go to the career site, you're going to be able to find. There

is no no. No, we are going cycling. Every aspect. What else? I think I think that's it for questions. Do you have any questions for me or for anything else? Alright Esteban. I really appreciate the damn you and your team are working on something incredible and unique, and you guys are really on to something. So, keep working hard and Well. Look, forward to seeing the updates in the future. Thank you for having me.
