Everyone's been making Friend Tech (FT) monitors from scratch, so I made one too. I decided to open-source the core of what I think is a reasonably robust system to bootstrap your FT tooling development. I use this on-and-off when I am active, and the pings are as fast as, if not milliseconds faster, the next FT monitor.
I spent a lot of time fine-tuning and coming up with a reliable way to backfill all users. I believe people can create (and have been creating) cool monitors or ecosystem tooling if they have access to more signals, such as their public Twitter data, balances/tx history of funding wallets, etc.
- Uses
/users/by-id/:idFT API to incrementally get new users - Leverages Twitter API v1.1 to bulk fetch user data
- Optionally sends new sign-up and first-key buy notifications via Discord webhooks
users.ts: Uses FT API to incrementally get new sign-ups.twitter-sync.ts: Uses Twitter API to bulk fetch Twitter data for FT users.parser.ts: Base chain transaction parser to scan transactions for first-key buys. This is what you'll need to update if you want to alert on other tx types, e.g. deposits or high volume for a specific key.

I'm very much a beginner at all things TypeScript/Blockchain. Anish Agnihotri's friendmex was a good starting point for another project I had worked on before this one. I gained invaluable experience to start creating more complicated systems.
Also thanks to @_GvAll and @DukeOfWapping for bouncing ideas.
