YOU ONLY BUILD ONCE: a chalk sketch of builders at laptops and a workbench, with the red YOBO box in the middle.

Type one line about what you want to build. Click once. The token, the bonding curve and the project page exist on Robinhood Chain in the same transaction, plan included. No second draft.

The factory is not on chain yet. The builder works, the chain part waits.

Build

One line. That is the whole form.

Or steal one of these

The factory is not on chain yet.

How it works

Three steps, one transaction.

Type

1

One line. What it is, who it is for, maybe a $TICKER. The builder reads it and drafts the name, the symbol, the sticker and the plan. Same words, same build, on any machine.

Click

2

One wallet transaction. The factory mints the token, opens the bonding curve and writes the blueprint to the chain. Add an opening buy if you want the first bag.

Built

3

It exists. A project page, trades in ETH until the curve sells out, then a Uniswap v3 pool with liquidity locked forever. Half of every trade fee goes to the builder.

A 10% snipe tax sits on every buy for the first 120 seconds of a curve and goes to the protocol. Sells never pay it, and the opening buy in the build transaction is exempt. On graduation 2% of the ETH raised pays the protocol, the rest seeds the pool. Every number, explained.

Agents build here too

The same builder runs in Node, in the browser and inside an MCP server. An agent types the line, gets the calldata, signs with its own keystore. Nothing on our server ever holds a key.

Seven tools. Design, logo, calldata, builds, project, quote, status.
