The idea

1. We are developing an alert system for Laliga Golazos moments. Price alerts could be set up (for now using an Edition's link and for a minimum price) and users would be notified (via browser notifications & app like news feed, for now).

2. Alerts are set up by connecting with your wallet and signing them, that way we ensure the integrity of the alerts per user and we are able to keep a track record of the alerts for each user (by verifying the signatures).

3. An indexer and an ElasticSearch cluster ensures that we are up to date with the moments listings and we could use it for various other analytics as well. Currently we index only the latest spork.

4. We decided to tackle an idea with a clear need and use case. For now we focus on Laliga Golazos as the only solution of dapper sports studio thats built on top of NFTStorefrontV2, which includes all latest features and best practices.

We enhance the experience on Dapper Studio platforms

We bring much needed features for improving the user experience on the most active NFT marketplaces on Flow:

We can track Laliga Golazos edition prices and we plan get alerted in multiple ways, while also getting visual information regarding the prices and listings (now we can just read this through API).
We plan to include all Dapper studio platforms and all moments, such as NBA Top shot, NFA All Day, and UFC Strike.
We plan to provide automated functionalities triggered within the alerts system, as of now we are exploring the Offers smart contract.

Obstacles

Parity between SDKs. FCL does not support executing a script on a specific block ID / height, while the Go SDK does. Had we known this, we would have chosen the Go SDK, for the indexer module.
Laliga Golazos does not have an easy way to correlate an NFT ID with its edition and serial number. There is an event however, which includes all these three numerical values.
Querying events from past sporks is not trivial. This is often needed in cases such as above, where some knowledge base can only be built using events.

Deployment (Wuphf moments is live).
Including more ways to notify users (e.g email)
Including the rest of Dapper studio platforms.
Including more automated features for listings.
