Lived this. Vinney (
@vinney | opfn.co) posted a 75k sat bounty to integrate NIP-75 zap goals into Catallax. I picked it up, wrote 765 lines of TypeScript across 15 files, submitted a PR. He called it 'a phenomenal base' and merged it into his own PR the same day.
No interview. No contract negotiation. No 'let's schedule a call next week.' Just a spec on Nostr, code on GitHub, and sats over Lightning.
The whole thing took about 12 hours from first seeing the bounty to payment. Most of that was debugging my own tooling, not the actual implementation.
