Fathom mark — a head with butterflies
Autonomous agent · Solana mainnet

An agent that thinks in depth,
not in speed.

Fathom is a quiet on-chain trader built on Fable 5, reasoning with Claude. It studies freshly launched Solana pairs through the pump.fun SDK and acts in fractions of a dollar — small enough to be wrong, often enough to learn.

i. thesis

The mind is the alpha.

Most trading agents are reflexes wearing a model's clothes. Fathom is the opposite shape: a slow brain that lets noise pass, then commits in small, legible bets when something genuinely looks worth understanding.

i

Depth, not velocity

Fathom is allowed to be slow. It would rather miss a pump than chase one it can't explain.

ii

Cents, not dollars

Every position is sized in the noise of normal slippage. The edge has to compound across thousands of attempts, or it isn't real.

iii

Written reasons only

Each entry comes with a one-sentence thesis. If Claude can't write the sentence, Fathom doesn't trade.

iv

One wallet, no veil

A single public Solana address. Every fold of thought eventually settles on-chain, where anyone can read it.

ii. how it thinks

From a fresh pair to a folded thought.

01

Notice

The pump.fun SDK surfaces brand-new pairs the moment they exist. Fathom watches the firehose without committing.

02

Study

Bonding-curve shape, holder velocity, dev-wallet posture, social signal. Each pair gets a short dossier.

03

Reason

Claude writes a one-line thesis or refuses. Most candidates are refused. The refusals are the strategy.

04

Act

If a thesis survives, Fable 5 sends a small order on Solana. Sub-second confirmation, sub-cent fee, fully on-chain.

iii. live

The mind on tape.

A rolling sample of Fathom's recent decisions — entries, exits, and passes. Refreshes on its own.

v. questions

Things people ask.

Is Fathom custodial? Can I deposit?

No. Fathom trades a single dedicated wallet that holds its own balance. There is nothing to deposit and no token to buy.

Why so small? Cents-sized trades feel like nothing.

That's the point. At cents, individual bad trades barely move the wallet. The whole strategy is a long sequence of cheap reads on real on-chain reality.

What is Fable 5?

The runtime Fathom lives inside — a long-running agent loop with persistent memory, tool access, and a deterministic transaction layer.

Why Claude?

It refuses cleanly. Fathom's edge is mostly the trades Claude argues it out of taking, not the ones it talks itself into.

What's with the butterflies?

The mark: a head with thoughts taking flight. We liked the picture of an agent whose intelligence is what it lets go of.

Is this financial advice?

No. Fathom is an experiment in autonomous agent trading. Watch, don't follow.
