Trenches pump.fun Forward Capture, 2026-08

A point-in-time observational dataset of Solana bonding-curve token launches. 730,850 observations over 85,442 mints across 4 venues, captured live from 2026-08-06T22:40:47Z to 2026-08-13T01:07:50Z at a 75.0 s poll cadence, with a derivability timestamp per field block on every row.

That last property is the point of the dataset. Most financial tabular releases carry one timestamp per row and leave the reader to argue about whether a feature was knowable at decision time. Here each field block carries its own tau__ stamp in epoch milliseconds, so leakage is a quantity you compute rather than a claim you make. The dataset ships with a worked example of the stamps catching a real leak: the post-reach block passes an as-stamped replay and fails an honest audit, because it resolves a median 20.52 s after the instant it is stamped with.

Quick start

import pandas as pd

features = pd.read_parquet("features.parquet")     # 85,442 rows, 103 columns
labels = pd.read_parquet("labels.parquet")         # 84,584 rows, 17 columns
panel = features.merge(labels[["mint", "path_completed", "n_obs", "segment"]],
                       on="mint", how="inner")     # 84,584 rows

import json
split = json.load(open("split.json"))
train = panel[panel["mint"].isin(set(split["in_sample"]))]      # 50,812 pump.fun mints
test = panel[panel["mint"].isin(set(split["out_of_sample"]))]   # 30,059 pump.fun mints

print(panel["path_completed"].mean())   # 0.011350, that is 1.135%

Loading through datasets:

from datasets import load_dataset

observations = load_dataset("Tr4m0ryp/trenches-pumpfun-forward-2026-08", "observations", split="train")
print(observations.num_rows)            # 730850

The point-in-time panel is the larger file and rewards column pruning:

import pyarrow.parquet as pq

table = pq.read_table("observations.parquet",
                      columns=["mint", "seen_at_ms", "gate_inputs__holder_count",
                               "tau__gate_inputs", "tau__reach", "tau__reach_read"])
print(table.num_rows)                   # 730850

What is in each file

observations.parquet is the instrument record: one row per poll per token, 730,850 rows. Column families are gate_inputs__* (24 vendor screen numerics), vendor_audit__* (12 vendor audit numerics), verdict__* and gate__<name>__ran / __passed (the live screen's decision over 6 gates), reach__* (35 dehydrated X columns), fold__* (10 chain aggregates), 7 chain scalars, and 10 tau__ stamps.

features.parquet is the modelling panel: one row per mint at first sighting, 85,442 rows and 103 columns, with curve-progress proxies excluded.

labels.parquet carries the outcome per pump.fun mint, 84,584 rows. Use path_completed (960 true, 1.135%), the chain reading. graduated (880 true) is the live resolver's independent call. y_theta_70 is degenerate in this release and is false on every row; see the limitations below.

split.json is a forward-only time split at 2026-08-08T21:38:15Z with a 10,800 s embargo: 51,311 mints in sample, 30,359 out of sample, 3,772 embargoed. It holds mint addresses, not row indices. No shuffling. Seed 20260814.

account_state.jsonl.gz is the terminal read of every pump.fun bonding curve account, 84,584 records, 960 with the completion flag set. It is the source of path_completed, published so the label is checkable.

curve_paths.jsonl.gz and launch_windows.jsonl.gz are decoded per-trade chain data: 342,341 priced bonding-curve events with slot, block time, transaction index, signed SOL and token amounts, post-trade virtual and real reserves, and the trading wallet. They cover 2026-05-08T22:33:37Z to 2026-06-10T17:41:33Z and do not join to the capture: the intersection with the 85,442 captured mints is 0 mints.

truth_set.parquet is 3,676 mints entered by tracked traders, with an adjudicated boolean outcome (304 true, 8.27%) and a generated English rationale. All 3,676 are present in the capture.

post_ids.csv is the dehydrated X layer: 59,915 rows of mint,post_id,seen_at_ms over 20,495 distinct post identifiers.

What is withheld

Post content is not published. Redistributing tweet text breaches X's developer terms, so this is a dehydrated release: text, author_handle, author_description, conversation_id and author_id are removed, and so are the vendor's copies of the token's social links (twitter, twitter_handle, website, telegram). Derived numerics are kept, because a count is a measurement rather than content: view, like, reply, retweet, quote and bookmark counts, follower and following counts, account age in seconds, post character count, and the verified, blue-verified, default-profile, default-avatar and protected flags.

To rehydrate, take post_ids.csv and call GET /2/tweets?ids=<up to 100 ids> with a bearer token. Posts deleted since 2026-08 will not return.

The raw vendor payload is withheld pending terms review. Each captured row held the vendor's API response verbatim, 133 keys. Republishing a commercial API response wholesale is a question this project has not answered, so the whole block is excluded. What is published instead are the 36 numeric fields the study actually consumed, as gate_inputs__* and vendor_audit__*. features.parquet is derived from exactly those.

Chain data is published in full. Curve paths, launch windows, account state, completion labels and split indices are decoded public Solana state and carry no restriction.

No credentials, keys or keyed endpoint URLs appear anywhere. Endpoint names only. The bundle is scanned before release by src/release/secretscan.py, which reads decoded columns rather than compressed bytes.

Limitations you must read before using this

The base rate is a property of the instrument, not of the market. The completion rate here is 1.135% (960 of 84,584 mints). The historical 832,941-launch corpus for the same venue runs at 0.198%. The vendor feed is weighted toward launches already near completion, so this dataset is roughly five times enriched. Report every rate against 1.07%, never against 0.198%, and state which population you mean.

There is a 69.09-hour gap, and it is not random with respect to time of day. Observations stop at 2026-08-10T00:37:48Z and resume at 2026-08-12T21:43:12Z. A second gap of 2.09 hours follows on 2026-08-12. The capture spans 146.45 hours and observes 75.27 of them. Because the gap is an outage rather than a sample, it removes the same clock positions on three consecutive days. Every mint carries a segment column, pre_gap or post_gap, and every result should state which side it was measured on.

Chain state covers pump.fun only, 84,584 of 85,442 mints. The other 858 mints launched on ray_launchpad (394), meteora_dbc (277) and sugar (187) and have vendor and reach data but no outcome. Do not pool venues in a rate.

The terminal label has precision 1.000 and recall 0.917, and recall falls with observation count. Judging the live resolver against the chain reading over 84,584 mints: 880 true positives, 0 false positives, 80 false negatives. Recall by number of looks is 0.9686 at 1 look, 0.9658 at 2, 0.9630 at 3 to 4, 0.9321 at 5 to 9, and 0.8333 at 10 or more. The resolver fires on absence from the feed, so a mint that lingered is the one it is slowest to catch. Prefer path_completed, and stratify by n_obs.

y_theta_70 is unusable. The per-trade curve-path pull for this population exhausted its RPC budget at 0.0 coverage, so path_status reads error:not_pulled on all 84,584 rows, max_progress_path is null throughout, and the peak-progress label is false everywhere. It is kept in the schema so the failure is visible rather than silently dropped.

The reach block is not derivable at first sighting. Over the 56,593 reach blocks present at first sighting, the corrected read stamp lands a median 20.52 s after the recorded stamp, minimum 15.60 s, 95th percentile 35.49 s, maximum 96.58 s, and never earlier: 0 of 56,593 resolve before their stamp. The block therefore carries tau__reach_read alongside tau__reach, and reach_derivable_at_decision is true on 0 of 85,442 mints. Every reach_* column is outside the admissible feature set. Additionally, reach__route is guest on all 346,972 rows carrying a block, meaning the credential-free fallback served the whole capture at roughly 1% of the primary route's throughput, so reach coverage is a floor.

1,225 mints (1.4337%) carry a negative age at first sighting, minimum -27.6723 s. A token cannot be observed before it is created, so this is a stamp error. The known mechanism is that the capture client writes seen_at before it issues the vendor call. It is unresolved and reported as a bound: read every observer-stamped field as derivable at seen_at + 27.68 s, which costs 28.2% of the 75.0 s cadence, or accept a lookahead of up to 27.68 s and say so.

Curve-progress proxies must not be used as features. features.parquet already excludes them. observations.parquet keeps them, under gate_inputs__progress, gate_inputs__market_cap, gate_inputs__liquidity, market_cap_sol, vault and vault_implied_volume_sol, because it is the raw instrument record. A screen on first_progress >= 0.70 returns a 30.4-fold lift at 100% precision purely by construction. The full 21-name ban list is in DATASHEET.md.

launch_windows.jsonl.gz was repaired. The source file is a multi-member gzip whose first member was truncated by an interrupted writer, so a plain gzip.open returns 130 of 999 records without raising. The released copy is recovered member by member and rewritten as one clean member.

Field reference: the tau stamps

Column	Meaning
tau__gate_inputs	derivability time of the vendor screen block, epoch ms
tau__vendor_audit	derivability time of the vendor audit block, epoch ms
tau__reach	as-recorded stamp of the X reach block, the poll instant
tau__reach_read	corrected stamp: when the X read actually resolved
tau__fold	derivability time of the chain fold aggregates
tau__chain_volume_sol	derivability time of folded chain volume
tau__fees_sol	derivability time of the fee reading
tau__market_cap_sol	derivability time of the SOL market capitalisation
tau__vault	derivability time of the creator vault address
tau__vault_implied_volume_sol	derivability time of vault-implied volume

A field is admissible for a decision at time t when its stamp is strictly less than t. Observer-recorded fields use the observation instant, never a vendor-supplied creation timestamp, and the resulting algebra is a bound rather than an identity.
