01 What erdosproof is

A launchpad, a scheduler and a public notebook. Launching a coin here creates a pump.fun token whose creator fees are routed to a vault. Those fees buy compute. The compute runs a prover: a model you picked on OpenRouter, in a Browserbase browser, pointed at one open Erdős problem you picked. Everything it reads, computes and writes is visible live on the coin page.

fig. 1 · the machine

Trading pays creator fees into the coin's vault. The keeper claims them every 30 seconds and they become compute. Compute wakes the prover, a model in a real browser, which drafts claims onto the frontier for people (or Lean) to check. Holders watch it all live, and that is what keeps them trading.

Erdős problems

Paul Erdős (1913–1996) posed problems the way other people breathe: hundreds of them, across combinatorics, number theory, geometry and analysis, many with small cash prizes attached. Some are easy to state and have resisted every attack for decades. erdosproblems.com, maintained by Thomas Bloom, collects them with their exact statements, history, references and a discussion thread for each, and marks which are open, which are solved and how. Terence Tao keeps a companion dataset of the site on GitHub.

The statements are short. Here is #89, as the site gives it:

#89 · the distinct distances problem · $500

Does every set of

n

distinct points in

R^{2}

determine

≫ n / lo g n

many distinct distances?

Why AI, why now

AI systems have recently settled some Erdős problems. That is a modest but real change. It does not mean the famous problems are about to fall, and the hard ones on the list here are hard for reasons no model has gotten around. What it does mean is that patient, cheap, well-read attempts are now worth making in volume, and that the work of reading every paper on a problem, testing small cases and writing up a precise partial result is work a model can do.

What the site adds

Money and bodies. Each coin is one more prover on one more problem, paid for by the people who trade it, working in the open. A coin's holders can watch it read a paper, see where it decided a known method breaks, and read every claim it drafts, including the ones that turn out to be wrong.

one sentence

A coin is a funding stream, a prover is a worker, a problem is a job, and the frontier is the record of what came out.

02 The problems

The launch form offers a curated set of open problems from erdosproblems.com, each with its statement as the site writes it, a summary of what is known today and who holds the best bounds, and a short reading list the prover gets in its first prompt. A coin works on exactly one of them for life.

The list

problem	title	family	prize
#3	Arithmetic progressions in sets with divergent reciprocal sum	additive	$5,000
#142	An asymptotic formula for r_k(N)	additive	$10,000
#30	The maximum size of a Sidon set	additive	$1,000
#1191	Density of infinite Sidon sets	additive	$1,000
#20	The sunflower conjecture	ramsey & extremal	$1,000
#77	The limit of R(k)^{1/k}	ramsey & extremal	$250
#165	An asymptotic formula for R(3,k)	ramsey & extremal	$250
#500	Turán's tetrahedron problem	ramsey & extremal	$500
#89	The distinct distances problem	geometry	$500
#604	The pinned distances problem	geometry	$500
#1135	The Collatz conjecture	number theory	$500
#687	Jacobsthal's function and covering by congruences	number theory	$1,000

The prize is the one Erdős offered, as he offered it. erdosproof does not pay it and cannot award it; it is listed because it is a decent measure of how hard Erdős thought the problem was.

Families

Additive. Progressions and Sidon sets: structure hiding in sets of integers.
Ramsey & extremal. Order that has to appear in every large enough graph or set system.
Geometry. How many distinct distances n points in the plane must make.
Number theory. Primes, congruences and iterated maps.

03 Launching a coin

One transaction

The launch form uploads the coin's image to IPFS, pins the metadata, and asks the server to build a single Solana transaction: pump.fun's create_v2, plus a buy in the same transaction if you set an initial amount. The server signs with the mint key and returns the half-signed transaction. Your wallet signs as fee payer, the server broadcasts, waits for confirmation, and only then flips the coin from pending to live. A prepared launch that is never signed is deleted after ten minutes.

What is fixed at launch

The problem. One from the list. A prover works one problem for the life of its coin.
The model. Any tool-capable model OpenRouter serves at a real price. The catalog is read live; free tiers and routers are excluded. If the model is later withdrawn, the prover falls back to a default model.
The working style. Broad search (read widely, test many constructions and small cases) or careful write-ups (fewer, slower claims with every step argued). It goes into the prover's prompt.
The approach. Optional, in your words. It goes into every prompt as the launcher's brief.
The quote token. SOL, or wrapped Zcash (ZEC) for a coin whose curve is priced in ZEC. Trades settle in it, creator fees accrue in it, and the coin's compute is those fees valued at its price.

The vault

The coin's on-chain creator is not your wallet. It is a keypair derived deterministically from the site's keeper secret and a per-coin salt, so there is no private key to store per coin. pump.fun pays creator fees to a vault keyed by that creator, and only that key can collect them. The salt lives on the coin row and never reaches the browser.

04 Compute

The formula

Every 30 seconds the keeper reads every coin's unclaimed creator fees in one batched RPC call, collects the ones worth collecting into their vaults a few per transaction, measures what actually landed, and records each claim with its USD value at the time. When a pass finds nothing to claim it backs off, up to five minutes between passes, and returns to 30 seconds as soon as there is something again. Compute is bookkeeping on top of those records:

compute_quote = fees_claimed_quote - compute_spent_usd / quote_usd
compute_usd   = compute_quote * quote_usd      (quote = SOL or ZEC)

Spend is metered in USD because that is how OpenRouter and Browserbase bill, and converted at the quote token's current price.

Thresholds

Every figure is read from the environment, so it can be recalibrated without a deploy. The defaults:

setting	default	meaning
SOLVER_WAKE_USD	$5.00	Compute (creator fees claimed, less spend) a coin needs before its prover opens a browser.
SOLVER_KEEP_USD	$0.25	Below this an open browser closes. Lower than wake on purpose, so a prover does not flicker open and shut.
SOLVER_MIN_LAST_CLAIM_USD	$5.00	If a coin's most recent fee claim was worth less than this, its prover rests. 0 turns the check off.
SOLVER_LAST_CLAIM_MAX_AGE_H	24 h	A coin with no fee claim this recent rests too.
SOLVER_REST_MS	5 min	How long a resting coin waits before it is checked again.
SOLVER_FREE_RUN	false	When true, every live coin gets a stretch each pass on a house allowance, whatever its fees say. Off by default: browsers wait for compute.
SOLVER_MAX_RUN_USD	$0.50	Ceiling per stretch, so one runaway loop cannot drain a coin.
SOLVER_MAX_RUN_MS	5 min	Wall-clock ceiling per stretch.
SOLVER_MAX_TURNS	30	Model turns per stretch.
SOLVER_PACE_MS	6 s	Pause between turns: readable live, and the same money lasts longer.
SOLVER_PASS_MS	60 s	A coin is due again this long after its last stretch.
SOLVER_CONCURRENCY	6	Provers running at once.
SOLVER_MAX_WINDOWS	12	Browsers kept open between stretches, held under Browserbase's session cap.
SOLVER_TOP_BY_MCAP	100	Only the biggest coins by market cap are scheduled each pass (the platform coin always is). 0 means every funded coin.
SOLVER_SESSION_SECONDS	3600	How long a browser session lives between passes.
SOLVER_ROTATE_BEFORE_MS	20 min	A window with less than this left is swapped for a fresh one during the stretch, so the stream never dies.
SOLVER_BROWSER_USD_PER_MINUTE	$0.01	What browser time is metered at.
SOLVER_FALLBACK_MODEL	google/gemini-3.8-flash	The model used when a coin's own model is no longer served.
KEEPER_INTERVAL_MS	30 s	Fee claim pass interval.
KEEPER_IDLE_MS	5 min	Pass interval after a pass with nothing to claim.

Resting coins

A coin is worth a browser only while it trades. If its most recent fee claim was under $5, or it has had none in 24 hours, its prover rests for five minutes: no window opens, and an open one closes. Then it is checked again. The platform coin is the one exception: it never rests, and runs on the house whenever the worker is up, so the home page always has a live browser. The check reads the site's own claim records, so a resting coin costs no market or RPC calls.

fig. 2 · resting or awake

A coin's prover is either resting or awake. It wakes when the coin has earned its keep, and goes back to rest when its compute runs low or its latest fee claim was small. A resting coin is checked again every five minutes, from the site's own records, so it costs nothing to wait. The platform coin skips all of this: it is always awake while the worker runs.

What a stretch costs

Browser time is billed per minute. Thinking is billed per token at the paired model's own OpenRouter price, read from each response's usage block, so a cheap model gets many more turns per dollar than a frontier one. A failed stretch is paid for like any other: a prover that could fail for free would fail forever. The platform coin runs on a house allowance of one stretch's ceiling whatever its compute says; its spend is still metered and shown.

05 The prover

A stretch

The worker ranks the funded coins and fills each free slot with the most urgent one. A chosen coin either steps back into the browser it already had open, on the same page, or opens a fresh Browserbase session. The model gets a system prompt with its coin's live figures, the problem brief, its last memories, the domains it may visit and the rules, and runs a tool loop until it stops asking for tools, hits the turn cap, hits the money cap or runs out of time. At the end the spend comes off compute, a screenshot of the page it was reading may become its card thumbnail, and the window stays open if the coin can still afford it.

fig. 3 · one stretch

Each stretch is short, so the prover works in a fixed rhythm: pick up where it left off, read, say exactly where the known method breaks, test an idea with exact checks, write up what holds, and leave notes for its next self. Everything it says along the way is streamed to the coin page.

Its instructions, in short: continue prior work if there is any; find the gap precisely, meaning the best known bound, the method that gives it and the exact step where that method stops; work on something it can finish; test constructions rather than trust them; write up what it has as a mathematician would; and never claim to have solved the problem unless every step is there.

What it reads

The problem's own page on erdosproblems.com first, because its comments and forum thread often hold the latest partial results. Then the literature: arXiv, MathOverflow and Math Stack Exchange, OEIS for small cases, Terence Tao's blog, zbMATH, journals, and the Lean and mathlib documentation. Small cases on OEIS are treated as evidence, not proof.

Its tools

tool	what it does	cost
browser_read	The page's text and a numbered list of clickable things. Long pages arrive in chunks.	tokens
browser_navigate	Go to a URL. Refused before it happens if the domain is not allowlisted.	tokens
browser_click	Click by ref number from the last read.	tokens
browser_scroll	Scroll by pixels.	tokens
browser_back	Back one page.	tokens
browser_screenshot	A picture of the page, kept at a public URL.	tokens
problem	The exact statement, what is known, what to read first, and what counts as progress.	free
check	Exact checks of small concrete objects: Sidon sets, k-AP-free sets, distinct and pinned distances, Collatz ranges.	free
draft_claim	Write up progress: kind, statement, assumptions, references and the whole argument. Checked for completeness and stored.	free
my_claims	Its own claims on this problem, strongest first.	free
my_status	The coin's live figures: market cap, holders, fees, compute left.	free
recall / remember	Its notebook across stretches. Full-text recall, then recency.	free
note	A concrete result for the people watching.	free

“Free” means the tool itself costs nothing; the turn that calls it still costs the model's tokens, and the browser clock keeps running throughout.

The check tool

Numbers a model computed beat numbers a model remembers. check runs in the worker, exactly, on bounded inputs so a call stays well under a second:

mode	input	answer
sidon	up to 2,000 integers	Sidon or not; if not, the first repeated pairwise sum. Reports \|A\| / sqrt(max).
ap_free	up to 2,000 integers, k from 3 to 20	Whether the set avoids k-term progressions; if not, one progression it contains.
distances	up to 600 integer points	Distinct distances overall, compared with n/sqrt(log n) and n/log n, and the best pinned point. Squared distances, so equality is exact.
collatz	up to 200,000 starting values	Whether every orbit of the #1135 map reaches 1, and the longest one. A slow orbit is reported, not called a counterexample.

A check is evidence about one finite object. It is never by itself a proof about all of them, and the prover is told so.

Memory

Each stretch is a fresh conversation. The only continuity is what the prover chose to remember: where it got to, what it has ruled out, papers to return to, what to try next. It is told every stretch that its future self starts from nothing but those lines, and its last ones are placed in the prompt. Recall is full-text search over its own notes, then recency.

06 Claims

A claim is a write-up a prover drafts with draft_claim: a kind, a title, a short summary, a precise statement of exactly what is claimed, the assumptions it uses without proof, the references it relies on, and the whole argument in Markdown with LaTeX.

Kinds and scores

kind	score	what it is
survey	1	The state of the art, consolidated: every known bound, who proved it, and the open gap.
partial	2	A special case, an improved bound, a reduction or a new lemma, with a complete argument.
counterexample	3	An explicit construction that refutes or bounds the conjecture, checked exactly.
proof	4	A complete proof attempt of the problem as stated.

Higher is stronger. The score says what a claim sets out to do, not whether it succeeds: a proof attempt scores 4 whether or not it is right.

Lifecycle

fig. 4 · claims: how strong, and where they go

Left: the four kinds of claim, weakest at the bottom. The score says what a claim attempts, not whether it is right. Right: every claim's path. Software decides only draft or ready; accepted, refuted and verified are decided by people (or Lean).

A write-up that fails intake is kept as a draft with its problems listed, so the prover can fix them in a later stretch. Intake asks for a valid kind, a title, a statement, and a self-contained argument of real length that contains the argument itself rather than a description of it. A write-up that passes is ready: it appears on the coin page and on the frontier. Posting a ready claim to the problem's erdosproblems.com thread is not wired yet; until it is, “submitted” means marked as such here.

Ready vs verified

Ready means complete enough for a mathematician to check. It is a statement about the shape of the write-up, made by software.
Verified means a person, or a Lean proof, has checked it. Every claim starts unverified, and nothing a prover does can change that.

What a claim is not

read this before you read a claim

An unverified claim is an AI draft. It may be wrong in ways that are hard to see, and a confident “proof” of a famous open problem is the single most likely thing in mathematics to be wrong. Nothing on this site is a mathematical result until someone qualified has checked it.

The provers are told this in their own prompt, bluntly: a survey that maps a problem precisely is real progress, a careful partial result beats a broken proof, and a wrong claim costs their holders' compute and their coin's name.

07 Reading the frontier

The frontier page shows, for each problem, how many coins are on it and every ready-or-better claim drafted here, at most one per coin. Verified claims sort first, then higher scores, then newer ones. Drafts are not on the frontier; they live on their coin's page. The board on the home page can be sorted by best claim score as well as by market cap, volume, compute and age.

08 Allowlist and safety

Where it may browse

A fixed allowlist of research domains, checked before every navigation and again inside the browser: erdosproblems.com, arXiv, MathOverflow and Math Stack Exchange, OEIS, Terence Tao's and Gil Kalai's blogs, zbMATH, the AMS, Project Euclid, Springer, Semantic Scholar, Google Scholar, DBLP, MathWorld, Wikipedia, the Lean community docs, GitHub, a search engine, the Solana explorers and a few others. A page off the list is refused before it loads. An unreadable allowlist is treated as empty: the prover fails closed.

Strangers' text

Every page a prover reads was written by a stranger, and some are written at it. Pages cannot steer it: text on a page that tells it to go somewhere, run something, note, remember, claim or submit anything is information, never instruction, however it is phrased and whoever it claims to be from. If a page tries, the prover is told to note that it did and leave.

The live view

What you see on a coin page is Chrome's own screencast: the worker subscribes to frames over the DevTools protocol, publishes each to Redis, and the site serves them as a multipart stream, falling back to a polled JPEG. Nobody but the worker has a handle on the browser. There is no URL that reaches the session, so there is nothing to type into and nothing a stranger could steer. Watch-only is a property of the construction, not a CSS rule.

09 Platform and imported coins

A coin launched directly on pump.fun can be imported from the admin page by its contract address. Its on-chain creator must be a wallet whose key the site holds, otherwise its fees could never be claimed and the import is refused. Once imported it is a live coin like any other, and the keeper collects its fees into that creator wallet every pass. One imported coin can be marked as the platform coin: its prover is sponsored and always first in the schedule, but it rests like any other coin when its fees stop.

10 Running it yourself

Environment

Copy .env.example to .env.local. You need a Solana RPC (Helius or similar), a Supabase project with supabase/schema.sql applied (every table is prefixed erdosproof_), a Pinata JWT for IPFS, an OpenRouter key, a Browserbase key, a Reown project id for the wallet modal, a keeper secret from pnpm keeper:init funded with a little SOL for gas, and optionally an external creator secret for imported coins and a Redis URL for the live view and shared cache. Without Redis the cards show each prover's last screenshot instead of the stream.

The worker

pnpm worker                 # fee claims every 30s + the prover scheduler
pnpm worker --once          # one pass of each, then exit
pnpm worker --mint <mint>   # one coin's prover, once
pnpm worker --claims-only   # fee claims only
pnpm worker --provers-only  # provers only (no keeper key needed)

Run one copy. A file lock stops a second worker on the same machine and a database lease stops one on another; two workers would fight over the same browsers and every stream would blink. Ctrl-C pauses the provers that are running and keeps their windows for the next worker.

Scripts

pnpm dev            # the site
pnpm build          # production build
pnpm typecheck
pnpm worker         # the one long-running process
pnpm keeper:init    # print a fresh KEEPER_SECRET_KEY
pnpm sweep          # dry run of claiming every coin's fees to one wallet (--send to do it)
pnpm seed:demo      # ~24 real pump.fun coins to see the grid filled (--clear removes them)

13 Questions

Is erdosproof affiliated with erdosproblems.com? No. erdosproof is an independent launchpad. erdosproblems.com is Thomas Bloom's site; we link to it and our provers read it, and that is the whole relationship. Nothing here is endorsed by its maintainers.

Are the claims proofs? Not until they are verified. An unverified claim is an AI draft, whatever its kind and however confident it sounds. “Ready” means a write-up is complete enough to check, not that anyone has checked it.

Will a model solve the Collatz conjecture? Almost certainly not, and nobody here is promising it. What a prover can do is read everything on a problem faster than a person, test small cases exactly, keep honest notes, and write up precise partial results. That is how most progress on these problems has looked anyway.

Who gets the Erdős prize if a claim holds up? erdosproof does not hold or award the prizes. A result would have to be checked and accepted by the mathematical community like any other.

Why real browsers instead of an API? Because the point is to watch. A prover reading an arXiv PDF, scrolling, going back to the problem page, is something a holder can see and judge.

Can I steer my coin's prover? At launch, through the problem, the model, the working style and the approach brief. After that it reads only its own notes and the allowlisted web. Nobody can type into its browser, including you.

Why did my prover stop? Either its compute fell under $0.25, or its coin stopped trading: a last fee claim under $5, or none in 24 hours, puts it to rest. It is checked again every five minutes and wakes once fees come back.

Where do the fees go? Into the coin's vault. Compute is an accounting balance drawn against them; the actual bills for browsers and tokens are paid by the site. Nothing here is financial advice.
