Transcript

Hello everybody, thanks for coming. My name is Luke Blackburn. I'm the co-founder of Octave. So Octave is a portfolio intelligent for digital assets. We are pretty much a data provider uh for financial data that is used for asset manager.

So um Arctab is solving um a bit of like problem we have with the D5 information D5 data. So basically uh the data is like all over the place. So uh we support up to 50 protocols. So you can get this information from the API for example um if if you guys try to uh index all this information by yourself it's it's really uh really hard and costly. So that's why we we provide this information.

Um also uh you can get all the information into the same place. So it's very good for the visibility and uh tracking all these complex protocol position can be really painful. So we solve all this information all this uh problematic. Um the beauty of like archive is like you can get data really fast. So uh through the API or through our application uh we we can also solve like complex problem with protocols.

So people come to us and have like protocol position which are not covered by anybody else and we can actually solve this uh problematic and give you this uh data. Um so uh octave is like pretty much two project. Uh the first one as I said is the uh the application. So we are like a dashboard for asset manager. So based on our data through the API you can get we actually build like a beautiful uh solution in which we provide a lot of tooling for asset manager to be able to uh solve their problems.

So uh you can do daily report uh you can do uh labeling categorization of your transaction. Uh you you can have build uh we we um we released a new dashboard like last week uh this week in which you can create multiple dashboard and there is like a widget marketplace. So you can actually play with the widgets and have like the dashboard that respond to your uh problematic. Uh the beauty of it is like you you could also build your own widget and we could uh add it into the platform. And uh this is one of the uh actual prizes that we uh ask you to do this week.

I'm going to give you more information in the in the next uh further away in the presentation. So uh the beauty of the uh octave API is is you don't like the front end, you can actually build what you want with it. So we provided the the raw data at the API level. So uh um pretty much you can access a wallet data. So if you need like a balance into a different chain you can actually have this with us.

Uh we provide a bunch of uh information about the network on all the chain we we cover for protocol position. Uh for example a curve we also support lighter u eer liquid eervium and stuff like that. Um so so we provide this in one single call. Uh you can also ask for one specific chain but you can also have the data in one specific call. So all the chain in one call.

Um we we do enrichment of transaction. So we don't only provide the radiator for the transaction. We also provide a next layer over it. Meaning that we're going to give you uh the uh the protocol in which you are interacting with the with the transaction if we know it. Uh we're going to give you all the asset the balance and the prices associated to that.

It's the same thing with the protocol position. you not only have the asset but you also have like the the value associated to the protocol position. Uh we support over 50 chains uh and also we are indexing about 17 uh chain for the transaction. We support uh most of the EVM uh pretty much 90% of the TLV or maybe even 95% of it. Uh we also support Solana for the transaction and also for the portfolio uh and and start net you can get information from start also.

Um so the first prizes uh the first challenge we offer you is uh to build in our ecosystem of the application the pro version of Arctav. So your goal is to build a widget in which you can use our own API. We can also bring any information from an an external ecosystem. uh we uh like defy lama we can provide you with an API of defile lama. So you going to bring uh you want to bring TLV of chain or uh any asset manager that would like to use defile lama as like another source of information to take better decision you can actually build a widget that do that we we are open to any kind of widget it can be a social one if you want to bring forecaster gaming EI agent it's really up to your imagination so uh we have like a widget marketplace so when you build the dashboard you can actually go into the marketplace and select the uh the widget you want to you want to put into your dashboard.

Uh some of them are free build by us. Uh if you build one of them, you want to sell it, we can actually do that also and give you a kickback on that. So we want to like an open ecosystem in which not only the client can build their own widget but also external people participate into it because we think people can come up with great idea and we can uh use that in our dashboard. Um the other price category is like the best application. So it's for you to guys to not build a budget but use the API himself.

Whether you need a protocol position, wallet and transaction like I said you can build anything with it. You can mix our API with your solution and other partner that are here today in the Auton. So it's really up to you to come up like a great great uh application. Um and uh this is the price uh you can win. Um it can be EI agent, it can be uh risk analytic.

we give you some of the uh possible like uh um idea that you can use to to uh to build something really cool. Uh how to get started? So basically it's super simple. Uh we ask you guys to go to get an API. So you go knock5-appi, you get an API, you come to us at the boot, we're going to give you some credits and after that we u you can clone the starter template.

So we actually build a template so you don't start from scratch. You put the API into the template and you're pretty much up to running to get information from the API. Uh and also you can go to explore the documentation. We provide all the endpoints, all the data type. Uh and as I said, if you have more question, you can come see us at the boot.

We're going to be really pleased to help you. Um so we have a partner which is defilema. So the we we we work with the file a lot in on the platform. We use them for like the price feed. uh one of our provider for that and uh they were really kind to be able to give us an IP key for you guys that if you want to use the file lama to build your solution we can provide you with a free API key for the weekend so you get access to all the D5 lama uh cool data and there is a lot of them um so you have the QR code uh on this page so the first one get you access to uh to get your keys pretty quickly uh the last one is the starter template And the middle one is the API documentation.

So you can take a picture and go there. Uh and that's pretty much it. So uh does anybody have any question? Yes. Right there.

Jack has a question. It's going to give you a microphone. Do you have any um like instructions in terms of like building widgets um or are we sort of working from the template uh UI to

I mean I mean the template is really to uh to bootstrap you it's not a widget himself it's like TypeScript react application we use shaden so you have some of the thing in in this thing but if you build a widget it's there is no like guideline about it it's just you build it as you want

and is there any kind of constraints in terms of like code language or um

no it's up to you I mean the goal is you to come you with a great idea we as I said we use Chadian so I would maybe encourage you to to use this but we don't have like templates specifically for the widget it's really like the idea behind with and we can actually after that um uh implement it in in our language to be able to put it into our uh ecosystem.

Fantastic. Thank you. Any other question? All right. Thank you guys.

Good luck.
