Every coin gets its own copy of a real worm larva's brain, simulated live. It feels every trade. Creator rewards go to SPAWN, not to the launcher. How?
Type anything. It reaches the worm's eyes as light.

A real worm's brain, a copy for every coin
01
The worm is real
BRAINWORM runs a simulation of a real sea worm larva's whole nervous system: all 2,675 cells and 26,881 synapses, exactly as scientists mapped them (eLife, 2025). Nothing invented, nothing trained. One copy runs live, and everyone watching sees the same worm.
Launch a coin and a fresh copy of that worm hatches for it. The first thing it sees is your ticker. After that it feels every trade of your coin, and nothing else: a buy touches its head, a sell its tail.
03
Every trade feeds the $WORM burn
Coins launch on pump.fun, and every SPAWN coin names SPAWN as its creator. So the creator rewards pump.fun pays on every trade go to SPAWN, not to the coin's launcher: 64% of them buy $WORM, and all of that $WORM is burned. Every buy also pokes the big worm above, live.
04
You can check all of it
Your browser runs its own copy of the worm and checks the server's every second. Every hour of its life is sealed into Bitcoin. Its tests were written down before they ran. All the code is on this site.
The short version is below. The full story, from the study to the digital worm to the launchpad, is on About; every test is on Tests; every line of code is on Docs.
Someone buys a coin→its own worm feels a touch on its head→the big worm is poked at the coin's own spot→neurons fire, the body swims→the creator reward: 64% burns $WORM, 36% to the team
A real connectome
A real nervous system.
A connectome is a complete map of every nerve cell and every connection between them. Ours is the published whole-body map of a three-day-old Platynereis larva: 2,675 cells, 26,881 synapses. We run it as it was mapped; nothing is invented or trained.
Why it matters: what you see it do comes from real wiring, not from a model someone tuned to look good.
One worm, live
Everyone sees the same worm
One simulation runs on the server, 30 steps a second, and streams to every visitor. Messages you type reach its eyes as light; pokes touch its touch sensors; a lamp in its tank closes the loop with its body.
Why it matters: it is one shared, living thing, not a video or a random animation.
Checked by your browser
Your browser re-runs it
The simulation is exactly reproducible, so your browser runs its own copy and compares a fingerprint of its state with the server's every second. One wrong number anywhere and the check fails, in public.
Why it matters: nobody, not even us, can fake what the worm does. See the live check
Sealed in Bitcoin
Every hour, on the record
Everything that happens to the worm is logged with its step. Each hour is sealed, chained to the last, and timestamped into Bitcoin. Anyone can replay any hour and get the same result.
Why it matters: its history can't be edited after the fact. Replay an hour
Tests written first
Science, not vibes
Each question we ask the worm had its rule written down and timestamped before it ever ran, and runs on the real wiring and on 50 scrambled copies. Passes and failures are both published.
Why it matters: results you can trust, including the ones that failed. See every test
SPAWN, the launchpad
Your coin, its own worm, your keys
Coins launch on pump.fun: they trade on its bonding curve, pay its fees, and move to its own exchange, PumpSwap, once the curve sells out. Every coin's worm can be rebuilt from its trades in any browser. Your wallet signs every transaction; the site never holds a key. All the code is published here.
Why it matters: a launchpad you can check end to end. Read the code
What it is
A real nervous system, not a metaphor
Every cell and connection of a three-day-old worm larva, traced from electron micrographs and wired exactly as published. Nothing invented, nothing trained. One copy runs, and everyone sees it.
Once armed, the first time a touch stops its cilia is the launch moment: logged, replayable, and drawn as $WORM's image. After launch, buys poke its head and sells its tail.
Its cilia push it through a virtual tank in a helix. Stopped cilia turn it or let it sink, muscles steer, startle brakes. A lamp closes the loop: what its eyes see depends on which way it faces. The physics is ours and listed in the manifest.
Each coin on SPAWN hatches its own copy of this larva, which feels that coin's trades and nothing else, and anyone can rebuild it and check. Every buy also pokes this worm at the coin's own spot. Coins are pump.fun coins that name SPAWN as their creator: 64% of the creator rewards SPAWN collects buy $WORM, and all of it is burned.
Drawn in a pixel font, one column per step. Each eye cell gets its strip's brightness; which strip is our choice.

01
The wiring, as traced
2,675 cells, 14,066 connections, 26,881 synapses, weighted by synapse count.
Real
02
A simple model runs it
Firing-rate cells. Each connection's strength is its synapse count, scaled so the wiring can't amplify itself. Known transmitters decide when the cilia stop. Nothing trained.

03
What you see
Each cell in its traced shape, lit by its activity. Sparks run from sender to receiver.

04
The body swims
Cilia and muscles drive a simulated body at about half a millimetre a second. With a lamp lit, where it swims changes what its eyes see. The physics numbers are ours.

05
One worm, one log
Every stimulus is logged with its step. Re-running the log reproduces every result.
Verifiable
06
Your browser checks it
Your browser runs its own copy and compares state hashes with the server every second.
$WORM's only contract address. Chat blocks all addresses and links, so any other address posted as $WORM is fake.
Stated plainly
The parts that aren't the worm
It can't read. Your message reaches it only as light. It understands nothing.
It doesn't choose. A tug shows which way its body turned, not a preference. Nothing here predicts prices.
The model is simpler than the animal. The transmitter is known for 79 of 2,675 cells, so almost every synapse is excitatory. Real neurons spike, inhibit and modulate.
Some choices are ours. The eye mapping, the light sensors' threshold, the poke cells, the swimming physics and the drawing.
Positions are partly placed. 1,199 cells at traced positions, 1,009 placed by segment and side, 467 fragments not drawn.
The body is ours. The glass outline, the swimming physics and the lamp are ours. Only the lamp feeds the body back into the brain.
Coins aren't the worm's. A SPAWN coin's buys poke it at a spot we pick from the coin's address, and each coin's own worm is a copy fed only that coin's trades. The worm knows nothing about coins or prices, and it doesn't pick winners.
Where the rewards go. SPAWN coins are pump.fun coins and pay pump.fun's fees: currently 1.25% of each trade on the curve, 0.95% to pump.fun and 0.30% to the coin's creator. SPAWN is named as every coin's creator, so those creator rewards, and pump.fun's creator share on PumpSwap after graduation, go to SPAWN, not to the coin's launcher. 64% of them buy $WORM, and all of that $WORM is burned; the other 36% stays with the team, and so do $WORM's own creator rewards. Every purchase and burn is a public transaction. Coins can lose all their value, and nothing here is investment advice.
