## Transcript

[Music] [Music] so hi my name is Julian as introduced I'm one of the three co-founder at arjon and today I want to talk about how we can bring ethereum to 1 billion telegram users I know this is kind of a cliche title and we've been talking about on boarding millions or billions of users for for many years but hopefully I'll convince that no we can actually do so and and yes it's kind of funny that we talk about the billion users why the reality is very very different if we look at the amount of daily active users of popular defi application we see that you know we make a few thousand daily active users on a for example we can zoom a bit more and look at some popular blockchains of the ethereum ecosystem and we see that you know arbitr L1 they do half a million daily active users Bas has been on a good role lately doing average 1 million daily active users but we are still very very far for the from this 1 billion and what's interesting is that if we keep zooming out a bit more and start looking outside of the eum ecosystem we might notice that there's something happening on ton a single tap to earn game on T called amster combat average 30 million daily active users we're not talking about the blockchain that's a single game but what I do find fascinating about amst combat is that it actually reached these crazy numbers in three month we've been building the eom ecosystem for almost 10 years yet a single game on T is reaching 250 million users in three months so the question is what's the catch what's the trick you may think that ton is such an amazing blockchain that you know millions of users are rushing to using it I don't believe this is the case what I think is that the secret source is actually telegram itself and it kind of makes sense when you think of it telegram is actually an amazing distribution Channel it's one of the largest social network with 950 million monthly active users we're talking about bringing a billion users to ethereum there you go that's your billion because it's a social network it has social EnV virality features baked in right you have butt you have messaging group chat and so on and I think that's the reason why these games on on T they manag to reach crazy numbers so rapidly something that a lot of people don't realize but telegram is actually very crypto-friendly it already has an you know existing web3 ecosystem I mentioned you know gaming telegram mini apps on T but you also have some kind of defi ecosystem on salana with trading buts averaging something like 60 million dollars per day and finally one thing one last thing that I think is important is the fact also that on telegram every single user is already logged in so you have a platform of a billion users that you can actually already know so I've mentioned tegram mini apps I'm sure many of you know what they are but still just to so we are all on the same page a tegram minap is basically a full-fledged web application that runs inside tegram they build with the normal Tech stack and they have access to some cool technical features for example if your phone enables it they have access to biometric and a secure Enclave they can have access to the telegram clo storage they've been a available since 2023 uh but what's fascinating is that they've been really built for the web through ecosystem and that shouldn't be underestimated so telegram mini apps are part of telegram strategy to actually bring their users to T and of course they've been fueling the growth of the ton Network so the question is can we bring these one billion users to ethereum instead of ton and I believe the answer is yes we can really build and I hope I will show you that in the remaining time of this talk we can build the perfect invisible non-custodial wallet for these 1 billion users and why do I say that I do believe we have two cast that we can play to our advantage the first one is that we we have now L to that scale for example Stark net achieved 867 transaction per second a couple of weeks ago and we know they will double or triple that in a few months with something called Kon native so we have layer tools that can actually support 1 billion users but we Al also have something that is fascinating is account abstraction today for example at arjon we have session keys in production we have social recovery in production we have pay masters in production and so using that we can build a platform for user and for developers so we've built a wallet a telegram mini app wallet and there's a few things that are very interesting the first thing is that there's no on boarding required that's really cool we can use biometric and you have the typical Argent model but what's even more interesting is that using a wallet you can send token to anyone on telegram even if they don't have a wallet so you can pick one of your friend a telegram contact and you can send them for example usdc and because we've we have integrated a pay master that friend can be onboarded in a second and use this usdc directly so now we have a solution to bring people from not knowing what web threee is to having a funded web three wallet that they can use directly in just one click as I've mentioned we've also built a SDK for dap and the the goal of this SDK is really to Leverage What something that's called session Keys unfortunately I won't have the time to explain what they are but they really enable mini dabs to build an experience where the wallet has become completely invisible and so this is for example the example of of a game oops sorry of a game being built on Stark net CL gladia pet hopefully I'll be able to make that work no sorry this is not going to work so I'll just explain what it was supposed to show so basically it's a game telegram mini app what's fascinating is that as a user when you click connect connect your wallet or connect your account like in web 2 what happen is that the wallet pops out tells you the authorization it's requiring as the user you say Okay approve the wallet disappears and now you can play the game for a month and the game can make transaction on your account they are secured because of session keys so for a month as a user you never see the wallet again so we really enable a web to like experience but fully on web 3 with a noncustodial custodial wallet and so unfortunately I wasn't able to show you the demo but I I really believe we have build an invisible non-custodial wallet on the layer two that scales so now it's really time to finally on board these 1 billion users to ethereum thank you thank you so much that was amazing Julian do we have a question we have space for just one question so who's going to be the lucky one no question it's everything clear okay here please all right hello thank you jul for a amazing talk uh could you please uh explain to me to the audience uh how like the new users that you're talking about like the people that don't have any wallets the people that uh you will be sending money to even though they've never even established anything uh beforehand how would they uh like like my grandma or someone how would she then convert it to Fiat to Fiat afterwards yes well I would say that's a question that the scope is outside of the wallet that's a general question how to offr from you know from crypto here what we are focusing is first of all onboarding people to crypto we're not yet focusing about on on offboarding them well what we want to achieve is really bringing all these people to having a funded web three wallet and today because today your grandma I mean it's it's important for her to go to from crypto to Fiat but we are also trying to build an ecosystem on chain an ecosystem on stable coin so I I think we should first focus on trying to onboard these people and and what we've shown here is that we can really on board these people in One Click because what would happen in practice is that you for example you want to you can send with a wet you can send 10 usdc to your grandmother and the way it will appear to her it will be basically just a claiming link on the direct you know the the private discussion you have with your grandmother on telegram she will click on that link and because there's no on onboarding on our wallet the wallet will pop up and automatically it will be funded with the token that you have Center and because we using something like a pay Master she will be able to pay transaction fees with this usdc so that means in one click she has a wallet that she can use to either send some usdc to one of your brother or one of your cousin or maybe she'll be able to use this usdc to pay for a coffee in a shop or just to play a game so to answer your question for the moment we're not focusing about the offr problem we really want first to bring these users and being able to action them in basically one click thank you thank you thank you
