[00:00] Hi, hello y'all. Welcome to the Uniswap workshop. Today I am gonna get you
[00:15] through all the Uniswap stack. So hopefully during this hackathon, during
[00:19] the weekend and moving forward, you know where to find all the resources in order
[00:22] for you to continue building in this like on-chain finance world. My name is Angela
[00:28] and most people know Uniswap as the place to swap, right? The place to
[00:36] transact on chain, but it's even more than that. Uniswap is today one of the
[00:41] largest decentralized exchanges in the world, more than 4 to 0.5 trillion in
[00:47] cumulative volume, but also more than 2.7 billion trades and more than 10
[00:54] million assets, more than 20 chains support, and a lot of products that goes
[01:01] beyond the protocol level and our interface products. So we're gonna get you
[01:05] throughout some of them today, starting with the AMM, which is this protocol that
[01:11] allows you to connect on one side, traders and on the other
[01:15] liquidity providers. I'm also gonna get you throughout the UniswapX, which is
[01:20] pretty much an intense based protocol that we have that connects like different
[01:24] on-chain and off-chain mechanisms for you to find the best price execution
[01:29] possible. We also have CCA, which is this continuous clearing auction protocol
[01:33] in order for bootstrap liquidity out there. We also have the Uniswap API,
[01:38] which it's pretty much a wrapper of all of our routing systems and also Uniswap
[01:42] AI skills, which is like type of fronts that you could plug your agents in in
[01:47] order to, you know, build faster. Starting with the protocol, everything started
[01:52] back in 2018 with the Uniswap B1 version of the protocol, and back in
[01:56] 2021 we launched Uniswap B3, which is pretty much like the the
[02:02] protocol where you can like swap all of these type of assets, but at the same time
[02:07] introduced concentrated liquidity. So back in the day, you had this like curve that
[02:12] allows you to trade across the whole curve and that it wasn't a bit efficient
[02:18] on the price execution level. So pretty much concentrated liquidity, what allows
[02:22] is like LPs to pretty much set the range of the prices they're gonna
[02:28] they're gonna provide liquidity in. So that allows from one side better. Yeah,
[02:34] pretty much yields execution or like fees execution for them and on the other for
[02:38] users is like a better price because the liquidity is concentrated at certain
[02:43] levels. What that allows is on one hand, yes, better price execution for people,
[02:51] but on the other that you got to active manage positions, right? So today
[02:56] there are currently four versions. I mentioned three of them from 2018, 2019, and
[03:01] then 2021, but today there are currently four versions of the Uniswap protocol.
[03:05] Back in 2025, a year ago, we launched Uniswap B4, and that one introduced
[03:12] this along with the whole previous stack, including concentrated liquidity. We also
[03:18] launched the singleton pool architecture where everything happens in one
[03:23] contract and then hooks, which is pretty much a new set of like custom logic
[03:29] scripts that you could add to the lifecycle code. So yeah, I'm gonna start
[03:35] with those. B4, again, the protocol level also includes these Uniswap hooks,
[03:41] which is solidity logic that you could add to the swap cycle, and it's totally
[03:46] optional. Like you could deploy your own vanilla liquidity pools, but you could
[03:51] also deploy your own pools and add custom logic if you wanted, or pretty much
[03:56] add on top of it your liquidity pools these hooks. How it pretty much work is
[04:02] like whenever you start a swap, the system is gonna check the before swap
[04:08] flag, and if you added any sort of sensitive like custom, it's gonna execute
[04:13] it. If not, it goes directly and execute the swap, and after this swap was
[04:18] executed, it also gonna check if you added any custom logic on top of it, and
[04:22] then finally ended up executing this. Important, you can use a hook for like
[04:30] serve many pools, but one pool can just have a hook attached. These are
[04:36] different like variables that you can edit, but we pretty much have like this
[04:41] where you could like interact at the lifecycle stage. We have before and
[04:46] after initialize. We have before and after liquidity. We have before and after
[04:53] remove liquidity. We have before and after swap, and we have before and after
[04:58] donate. At the end of this presentation, I'm gonna give you a QR code where you
[05:03] can have access to this presentation, but if you're thinking on exploring
[05:08] before hooks at some point, you just gotta go to this before template, which
[05:12] is pretty much like some sort of scaffolding repo that we built to make
[05:16] builders build hooks easier. So yeah, this is pretty much the repo, but we
[05:23] also, as Uniswap Labs, we've been building more and more hooks that you
[05:27] could leverage if you want, not just during the hackathon, but moving
[05:30] forward. If you get our developers.uniswap.org documentation, you could
[05:36] find this section here, which is Uniswap Labs hooks, and the different ones that
[05:40] we have. If you click here on link, you're gonna find the code, but also the
[05:44] whole explanation to the architecture and stuff. We recently launched
[05:48] permission pool hooks, and also a stable pair hook. Pretty much permission pools,
[05:55] and you could take a look to all of them, but permission pool is like
[05:58] for issuers that let's say are looking to, you know, whitelist the
[06:03] requirements, certain requirements where just a few wallets can interact in like
[06:08] certain, I don't know, ranges or time, whatever. This allows you to, instead of
[06:12] like creating the hook from scratch, you could just like customize it in your
[06:17] own needs. And if you're a user, you could also interact with hooks, because
[06:23] today you could go to the explorer page and look for pools, and some of the
[06:28] pools now has this like label where you could have like different pools,
[06:33] including the official ones that I just showed you, which is this one is a stable
[06:37] pair hook. We also have the permission pool hook, but also the community ones.
[06:41] And if you're building one of the hooks that you need to add to the interface
[06:45] level, you could also apply to those. If you go to developers, we allow list most
[06:54] of them automatically, but if you also need any some sort of allow list, our
[07:00] team can help you allow list your hook here at the interface level. So in this
[07:05] time, you can interact with liquidity pools with this certain logic outside and
[07:11] also in our interface. And lastly, if you're looking for some like hook
[07:17] inspiration, this is our hook list. Pretty much all of the hooks there are
[07:22] custom allow list in our interface. You could go and take out and check all of
[07:28] the addresses of these hooks, but also, you know, the code logic of most of
[07:33] them. These is community hooks that has been allowed listed in our interface, not
[07:38] UNICEF Labs official hooks, just as a disclaimer. So yeah, I just mentioned at
[07:44] the protocol level, our last version of the protocol, which is before hook that
[07:48] introduces this like single to contract, but also hooks. And now we can move
[07:53] forward to the UNICEF X system. This is just like an intent based protocol that
[07:58] put together both systems, the AMM that I just mentioned, and then like a private
[08:05] system of market makers that also, you know, look forward to give you the best
[08:11] price execution possible. So when you go to the interface, for instance, as a default
[08:15] option, you have this here that includes UNICEF X. In the backend, what we have
[08:20] is an RFQ system that connects different mechanisms, including private market
[08:26] makers. They are actively quoting in order to give you the vast price
[08:30] execution. So what happens in the backend is like, I don't know, I want to
[08:35] trade ETH for USEC. One of these private market makers are going to quote, and if
[08:41] that price is better than the AMM level, so then I'm gonna get that price. If not,
[08:46] I'm gonna use the AMM. So when you're using the UNICEF interface, you pretty
[08:52] much are having the vast price execution because we have these two mechanisms,
[08:58] both on-chain and off-chain. If at some point you are one of these market makers
[09:05] and you'd like to be part of this exclusive order network that we have,
[09:08] which is pretty much like an exclusive window for you to quote and for you to
[09:11] be part of this mechanism, you could also reach out to us and definitely we
[09:17] get you if you meet certain criteria to be part of that network as well. So I
[09:23] just mentioned the protocol and then UNICEF X, which is pretty much part of
[09:27] these routing possibilities that we have in order to provide users and builders
[09:33] out there with the best price execution possible. Now, this is not
[09:38] related to the protocol itself, but it's related to the ecosystem which is the
[09:42] UNICEF CCA, pretty much like an auction mechanism where if you're
[09:48] launching a token, usually the developer has certain advantage at the beginning
[09:53] or the first address is to come has certain advantages at the beginning. So
[09:58] pretty much what this CCA does is like an auction mechanism where in certain
[10:03] time period or depending on what the developer said, everyone is like pretty
[10:08] much bidding or sending an auction in there. And then once that time happened, it
[10:14] is pretty much gonna like give like a like an average price of that. So that
[10:20] helps for like different purposes, for example, auction or like TGEs. In this
[10:27] case, in auctions, we've been like working with like different projects out
[10:32] there, but this is completely open source as well. So you could also launch
[10:35] your own auction even if it's not like the verified one. But we also use
[10:41] that for like lunches in general, where we do have this in the
[10:47] vacuum using CCA, but also allow listing other token launchers that use CCA's
[10:54] in the vacuum as well. This one in particular is available in ARK,
[10:58] in Robin Hood Chain. You could take a look to it and we also have pull straight.
[11:03] So CCA pretty much is like a liquidity bootstrap mechanism, if you're looking
[11:08] to interact with tokens at some point. And then one of the ones that, in my
[11:15] opinion, makes like integrators life easier out there is the Uniswap API that
[11:20] pretty much wrap up all of our routing mechanism, including both the AMM and
[11:25] UniswapX. And this is pretty much a web tool API, where you can get some quotes
[11:33] and prizes and we have different endpoints for you to interact with our
[11:36] system, without having to create like solidity code, or even just like having
[11:44] to integrate with our interface to just get the best of our ecosystem throughout
[11:48] an API call. There's two important things in here. The first is like, in
[11:54] order for you to interact with API, your users, you as an integrator has to take
[12:00] permit to in consideration. So if you approve permit to in consideration,
[12:06] there's another signature for your user. It's totally optional, but just giving you
[12:11] the heads up that in order for you to, you know, integrate Uniswap API, you need
[12:16] the transaction, you get the quote, you need the permit to approval, or just the
[12:22] signup transaction, if you're not looking to integrate that one. And we have
[12:26] certain like endpoints, right? So we do have the swap ones, and then we have
[12:31] chain swapping. Chain swapping is pretty much if you're looking for someone to
[12:35] get, I don't know, they have a token in certain chain and they need a token in
[12:41] any other chain, we have chain swapping endpoints in order for for you to do
[12:46] these cross chain interactions. And then I don't know if you remember, but AMM
[12:52] protocol in the v3 version, we have concentrated liquidity, which is this
[12:57] curve where you set these ranges, right? What allowed us this is like in one hand,
[13:03] we have best price execution for both, it's positive for both LPs and traders,
[13:09] but on the other hand, you need to active managing those positions. So think
[13:15] about you having a particular strategy, you could use the equity provisioning
[13:21] endpoints, think about your agent having to manage some of these positions, you
[13:26] also have LPs, endpoints, and you have some utilities, right? Such as checking
[13:33] if any KYC token has some permission, you could also use that token, especially
[13:39] these days with like stocks and tokenized stocks, that utility is really
[13:43] important in my opinion. You could also get support chains, right? If you're
[13:49] looking to integrate with a particular chain, whatever, that's also important, get
[13:53] tokens, get pool state, get wallet delegation. Something important for this
[13:57] hackathon in particular is that we're looking for having good feedback on
[14:02] your end, so if you encounter any bloggers, let us know, because from that
[14:05] point of view, we're gonna continue like shaping more endpoints that might be
[14:09] helpful for you in the future. So yeah, you could go to developers.uniswap.org,
[14:14] you find this API reference in here, and from here you could pretty much copy,
[14:20] paste, and interact with C URL code, Python, and TypeScript code, or you could
[14:28] also, if you're looking for any contracts in particular, inside that same site,
[14:32] you have deployments where you find all of the protocols that we have, all of
[14:36] the chains that we have, you don't have to worry about it. You can just connect
[14:40] your agent with it, and so in that case, you're filling, you know, it's like
[14:47] giving the certainty to these agents that you're interacting with the right
[14:50] contracts in our ecosystem as well. And if you want to make it even easier, if
[14:56] you go to developers.uniswap.com,
[15:00] claim your own API keys.
[15:01] By the way, I didn't mention it, but the API is totally free.
[15:06] You pretty much can grab one of these API keys
[15:09] and give it to your agent.
[15:10] So yeah, pretty much we have skills for all of our stack
[15:16] across all of our protocol.
[15:18] But that includes CCA, if you want
[15:20] to bootstrap any liquidity in particular,
[15:23] if you want to interact with permission pools, which
[15:25] is this hook that I mentioned, if you
[15:26] want to integrate with the B4 protocol,
[15:29] if you want to integrate with the LP endpoint,
[15:32] swap integration, you name it, there's
[15:34] plenty of possibilities for you to interact with,
[15:37] including trading tools such as the BCA bot, index bot,
[15:45] and copy trade.
[15:46] So yeah, there's plenty of possibilities
[15:48] for you to interact with.
[15:50] And today, at East Global Tokyo in particular,
[15:53] we have two open tracks, or pretty much one,
[15:57] and like different possibilities.
[15:59] Our track is like best Uniswap stack contribution
[16:04] for both type of hackers, the ones that
[16:06] are starting from scratch and the ones that
[16:09] are building on continuity tracks, which
[16:12] means we don't have any strong requirement on which side
[16:16] of the protocol for you to build,
[16:19] which is one year to build whatever is exciting for you.
[16:23] And if you find any way to integrate Uniswap in it,
[16:26] so that's perfect for us.
[16:28] So you could build on top of any side of the protocol, B2, B3,
[16:33] B4.
[16:34] You could interact with the ZCA.
[16:37] You could interact with the API.
[16:40] Or you could just like do, I don't know, contract calling.
[16:43] Or you could just build your own front,
[16:47] and there's plenty of possibilities.
[16:49] What I would love for all of you to do
[16:52] is instead of focusing on how to integrate the stack,
[16:57] focus on what is exciting for me to build.
[17:00] And in the middle, if I can integrate Uniswap,
[17:03] that would be amazing.
[17:04] My only, or our only qualification requirement
[17:09] is to add a feedback MD file in your REPL.
[17:13] And pretty much all of the instructions
[17:14] are here in the qualification requirement,
[17:17] pretty much letting me know all of the struggles
[17:20] that you had during your integration.
[17:22] And I promise we're going to do our best
[17:24] to make that integration since less in the future.
[17:27] So yeah, whether it was CCA, protocol level, API, Uniswap X,
[17:33] even if you find any way to interact with the RFG system,
[17:36] let us know.
[17:37] We're here to build together.
[17:39] So yeah, pretty much best Uniswap stack
[17:43] contribution for both from scratch and continuity.
[17:47] It is the same track.
[17:48] It's just that if you're building from scratch,
[17:50] you're going to be able to see the continuity
[17:52] and the opposite is also valid.
[17:55] And yeah, pretty much all of the questions that you have
[17:59] or you might have should live under developers.uniswap.org.
[18:03] This is just the QR code to the presentation
[18:05] in case you have any, you know,
[18:08] do not remember any other particular links.
[18:12] Everything should be there.
[18:13] If not, I'll be in the booth.
[18:15] And me and my team, we're going to be there.
[18:17] I really encourage you to integrate with all of the stack
[18:21] and for real be transparent and honest
[18:22] on like where's the problems that you encounter.
[18:26] We're going to work hard into improving
[18:28] that experience for all of you.
[18:30] And yeah, pretty much, thank you so much.
[18:33] Happy to have you during the weekend
[18:35] and let us know if you need any help.
[18:36] We'll be there to support.
[18:38] Yeah, thank you.
[18:45] I think we have questions, right?
[18:48] We have questions?
[18:49] Oh yeah, you have a question?
[18:50] Yeah, sure.
[18:59] Yeah, I mean, if you're looking to build one,
[19:04] yeah, that could be also a possibility, yeah.
[19:08] Any other?
[19:11] We good?
[19:12] Cool, thank you all.
