Quickstart

You need Node.js 20 or later, the Terrarium folder, and a wallet in your browser for the launch step. There is nothing to install: the one dependency, ethers, ships inside the folder.

See it first (no money, no chain)

Open the Terrarium folder and run launch.bat. The site starts on http://localhost:6150.
Open /lab. Move the sliders, press Crash price 15% and Send fees, and watch the walls report.

Run a paper organism

Paper mode sends no transaction. It needs a coin to read a price from, or it uses a made-up price.

MODE=paper
ORG_ID=test
PAPER_FEES_ETH=0.002

Save that as .env, run node engine/runner.mjs. Every beat it receives 0.002 ETH of simulated fees and the journal fills. Files appear in data/test/.

A paper organism without a coin uses a made-up price. The site never presents it as a real coin.

Run a live organism

Open /launch. Design it, create its wallet, launch the coin, copy the two files it gives you.
Put .env and organism.json next to launch.bat.
Run launch.bat. The runner and the site start.
Open /coin?id=<ticker> and the Verify tab.

The details of each step are in Launching a coin and Operating an organism.
