 My talk will be about what's next for the gas station network. And I am LaRoz Siri, the CEO of Tabuki. And the problems that we're working on are removing roadblocks to the mass adoption of decentralized finance. And the gas station network is an important part of that. So when do we get to mass adoption? We think that we're going to have to figure out, how do we create a type of familiar experiences that provide the ease of use of Web 2? But if we're going to be putting life savings of people at risk, then we also have to make it secure. And it's best if we figure out how to do that in a way that doesn't compromise on the decentralized security of Web 3. So we want to get to Web 3, but with an experience that's very familiar, and it's sort of a, you don't really have to know what's going on behind the scenes. So the next step is clearing the path to mass adoption. And we have three phases for this. The first one, creating the gas station network essentially allows users to interact with the Ethereum blockchain without needing to worry about having to pay gas for transactions. We abstract that away. So it's like we're creating this tall free road for Ethereum. And this is something we deployed live on Mainnet. But it right now requires support of GSN, the support of the GSN more logic inside the contract that wants to benefit from the GSN. So the next step, which hopefully I'll have time to demo quickly here, is the GSN sponsor model that allows us to extend this toll free road. So it can interact with any contract, including contracts that have already been deployed, which are the big contracts right now that are getting some usage, like the MakerDial contracts. Otherwise, if we don't figure out how to do this, then adoption for this new standard would be dramatically slowed down, because we would have to wait until everybody redeploys their contracts. Now, what's interesting is that we figured out how to extend the GSN to existing contracts in a way that also allows us to solve one of the cybersecurity issues that are also roadblock to mass adoption. So right now, if you want to benefit from decentralization, you need to deal with the complications of not only having to pay for gas, but also understanding key management and worrying about the security of your devices. And we think it's possible to create a new standard where that is not a concern. And we have this as a working POC right now that's going through security validation. And the goal is to establish a wide alliance of support so everyone can benefit from this. And you don't have to be a crypto nerd or a cybersecurity expert to use all this stuff. So essentially, the users in the system are creating their interacting directly with a gas station network. And then they're being routed, their gas fees are being paid for through GSN sponsors. This could be infrastructure providers like Infura that now get to monetize all their traffic. It could be wallet providers, or it could be smart contract protocols like MakerDow. And the demo I'll be showing will be a collaboration that we have with MakerDow that allows gas to be paid and died. And this would work, in principle, with any token that has a Uniswap ETH trading pair. So then you're routing through the GSN, and then the sponsors are paying for the gas. And they might be charging you in Fiat. And to get this to work, you have to represent the user on chain somehow. This is where the sponsored user vehicles come in. Essentially, we're putting everybody on this toll-free road by creating this proxy account for them that they interact with everything else. Every other contract, there's an opportunity there to introduce some neat features. So the gas station network is done, and the sponsored user vehicles are something that we're working on. So just a quick recap. DAP onboarding was a mess before the gas station network. I mean, it took us a month to KYC link our bank account to an exchange and get ETH to pay for the first transaction. And many users that would be a good fit for the ecosystem don't even have a bank account. So if we're talking about banking in the unbanked, that's a major roadblock. Many parts of the world, people don't have access to bank accounts. So it would be hard for them to get ETH. So the gas station network, it's very direct. Essentially, it could be a web-to-experience. If you don't need ETH, you don't need a wallet. And this is something that is now working live on MayNet. And our partners have helped us get to that point. So the Ethereum Foundation, Consensus, MakerDAO, provided grants, opens up and done security auditing. Portists have done a lot of the UX work. And we have these great demos with Burner wallet thanks to Austin Griffith. So quickly running out of time here. So with the gas station network, instead of interacting directly with Ethereum, you would be interacting with relays that then routes to GSN or other contracts. But then that limits you only to contracts that have support for this. So the next step is baking all of the logic for working with the GSN into a separate GSN-sponsored contract. And then this contract can route your requests to any contract, but because the user is not actually represented on-chain in the other way, like they don't necessarily even have a wallet, then you need to create an on-chain representation for them, which is the user vehicle that I've been speaking with just to keep with the road metaphor. And then there, that's an opportunity. So the GSN-sponsored allows us to create business models for wallets and infrastructure providers that currently maybe are trying to figure out their options. And essentially this is a way of allowing wallets to charge a small transaction fee in a way that actually adds value. So you could do something like sell your users $5 worth of gas for like $6, right? And you don't even have to KYC and AML them because you're not sending them ETH, you're just paying for their gas behind the scenes. So that should make it a lot easier. And then DApps can decide to subsidize their users as part of the onboarding costs, so that's also an option. And what's nice is it also solves a key problem in getting decentralized privacy mixers to work. And you have the problem, how do you withdraw from a decentralized privacy mixer if you don't have an ETH? So looks like we have time for a quick demo and this is a collaboration with MakerDAO and essentially changing the MakerDAO contracts is too hard. But if we bake all the logic for paying for the gas and not an ETH in DAI, for example, we don't have to change the contracts. So you might wanna do this because it's inconvenient to have to maintain a separate balance in an ETH if you already have DAI and you have Uniswap support for it. Why not just figure out a way to take care of that which is what we've done. So essentially you have this specialized DAI sponsor and you're committing to paying for your gas in DAI and it takes your DAI and it swaps it out for ETH, it pays for the transaction and gives you the remainder. And I think I have exactly time to do a demo. Hopefully this works, which is not a given. All right, so this is an ETH-less wallet demo. It is, right now I'm gonna be doing this on Rinkabee because it's gonna be very hard to do this on Mainnet right now with the demand on Shane. So there's no ETH here, there's no tokens, it's just a signing account and we wouldn't necessarily even need MetaMask to do the signing. We could bake the logic into some other part of the application but this is convenient for demo purposes and then I'm going to be transferring to this other wallet, which also doesn't have ETH, and I'm gonna be transferring one bot, one basic attention token, okay? So one bot and the fees will be paid for in DAI. So this is a real transaction right now on the Rinkabee testnet. MetaMask asks me to sign the transaction I don't have any ETH, so it's just a signing function. Already ran out of time. And I won't wait for this to mine. I'll show you what this looks like when it is mined. So essentially the transaction is not coming from the user because the user doesn't even necessarily have anything on Shane. It's actually coming from one of the GSN relays and then that's being routed to the Relay Hub contract which is part of the GSN. Then if you see down below here then the user is paying for the gas, like sending the GSN DAI sponsor $1.4 as a maximum gas prepayment and we actually transfer the bots and then it turns out the transaction was a lot cheaper, it just cost nine cents. So we charge a transaction fee, we give the user $1.29 back and we swap out 15 cents for ETH to pay all the participants in the system and that's it, like it just works and maybe yeah, the transfer was complete and we have a transaction and the transaction, no ETH was involved, everything was paid for in DAI and imagine we could just do this from a browser. So yeah, thank you.
