A complete place to start.

Tsiolkovsky delta-v
Payload sensitivity table
Propellant and dry-mass accounting
Exact token contract and pair inspection
Bounded ERC-20 transfer activity explorer

Run locally

npm test
npm start

Open localhost:3000. The technology runs with no API key. Live chain and DNS reads use public providers.

Deploy in your account

Extract the archive and upload its contents to a GitHub repository you control. Import that repository into Vercel, or run npx vercel --prod in the extracted folder. The included configuration sets the output directory and tests.

Return to the Deploy studio to publish your project, token pair and repository on the public build board.

This download contains only this standalone project. It includes no account credentials.

METHOD

What it calculates.

Ideal delta-v = Isp·standard gravity·ln(initial mass/final mass), where payload is included in both masses. g0=9.80665 m/s².

LIMITS

What the evidence means.

No gravity or drag losses, staging, structural design or flight guidance. Not SpaceX telemetry or a launch quote.

The funding planner does not transfer tokens or route rewards. Deploying this repository does not imply company endorsement or investment value.
