pump.fun launch-tape data: datasheet (Avasis / QuantBase, 6 Nov 2026)

What this is. Per-launch evidence about how a pump.fun token was launched: who bought in the first slots, how many of those buyers were bundled, serial snipers, or shared a funder with each other, and what the creator wallet did before and during the launch. All of it is derived from public Solana chain data. It is data and risk tooling, not trading advice. Nothing here predicts price, and a verdict is not a buy or sell signal (see "Honest limits").

Coverage

Launch-tape features (`meme_tape_features`)	since 13 Mar 2024 (sparse early), ~70-83% of launches/day in the last week
Live trade tape	real-time, ~6 h rolling retention; the first 30 s after a launch is read live
Batch features land	~90 min after a launch (p50, measured)
Creator records	lifetime launches and graduations per creator wallet, plus funding-cluster aggregates
Holder snapshot	RugCheck top-10 share, only after graduation (81 of 7,430 sample rows)

The free sample

pumpfun-launch-sample-20261030-20261105.csv.gz (0.65 MB; 1.8 MB as .csv after gunzip). SHA256SUMS lists the hash of the .csv.gz as downloaded and of the .csv after gunzip (the .csv line fails sha256sum -c until you have unpacked it).
7 full UTC days, 30 Oct 00:00Z to 6 Nov 00:00Z 2026. A deterministic 1-in-32 sample of all launches: a mint is in when int(md5(mint)[0:8], 16) % 32 == 0, so anyone can re-derive the same set. That gives 7,430 launches (952-1,261 a day).
37 columns: the raw evidence fields below + verdict, reason_codes (pipe-separated) and verdict_basis.
Public chain data only: mint, symbol and creator wallet are on-chain. There is no personal or off-chain data. Symbols are cleaned (Unicode NFKC, hidden/control/bidi/tag characters removed, max 16 code points) because launchers can put anything in them.
Verdicts in the sample are computed from the batch features (bundles and funder groups included). The live API answers fresh launches from the live 30 s window and says so in not_evaluated.

Sample verdict mix: WARN 3,784 (51%), DANGER 2,341 (32%), SAFE 1,305 (18%). 1,820 rows (24.5%) have no batch tape features; those can only be WARN or DANGER (no evidence is never SAFE).

Column dictionary (sample CSV)

window_s, tape_complete, tape_note	launch-tape window length (s) and whether the tape had a gap
pct_supply_first_2_slots	% of supply bought by anyone in the first 2 slots
creator_supply_pct	% of supply the creator bought in that window
creation_slot_buyers, first2_slot_buyers, early_1s_buyers	distinct non-creator buyers in the creation slot, first 2 slots, first second
serial_snipers	early buyers already seen sniping OTHER launches earlier
bundle_txs, bundled_wallets, bundled_supply_pct	multi-buyer bundled transactions at launch and the supply they took

creator_sold_in_window	creator sold inside the tape window
cohort_deployer_funded	early buyers funded by the deployer wallet
name/symbol_collisions_7d, image_collisions	metadata reused by other launches (clone detection)
creator_launches / _graduations	creator wallet's lifetime totals
cluster_size / _launches / _graduations	the creator's funding cluster (wallets linked by funding)
top10_ex_pool_pct	RugCheck top-10 holders excluding the pool (post-graduation only)
verdict, reason_codes, verdict_basis	see below

How a verdict is computed (published live at `GET https://agents.avasis.ai/v1/sol/launch-intel/info`)

Fixed thresholds, calibrated on 32,539 launches (24 h to 6 Nov 09:00Z): WARN near p90, DANGER near p99.

Dev launch buy >= 10% WARN / >= 20% DANGER of supply.
Other wallets' first-2-slot supply >= 15% / >= 30%.
Bundled wallets >= 3 / >= 6; bundled supply >= 5% / >= 15%.
Serial snipers >= 4 / >= 11; 1-second buyers >= 6 / >= 16.
Shared-funder group >= 3 / >= 5; any early buyer funded by the deployer: DANGER.
Creator launch farm (>= 20 launches, 0 graduations) or a funding-cluster farm (>= 5 wallets, >= 50 launches, < 0.5% graduate): DANGER.
Serial launcher (>= 3 prior), dev sold early, clone metadata (>= 5 collisions or a reused image), RugCheck top-10 >= 30%: WARN (top-10 >= 50%: DANGER).
The worst reason wins. No launch evidence is never SAFE (INSUFFICIENT_LAUNCH_DATA). Every reason carries its value and threshold.

Most frequent reasons in the sample: SERIAL_LAUNCHER 2,118, CLONE_METADATA 2,101, DEV_SOLD_EARLY 1,813, CREATOR_LAUNCH_FARM 1,717, INSUFFICIENT_LAUNCH_DATA 738, EARLY_SUPPLY_CONCENTRATION 689, SERIAL_SNIPERS 638, EARLY_1S_BUYERS 603, CLUSTER_LAUNCH_FARM 372.

Live accuracy of the 30 s window vs the batch features (prod, 230 launches): first-2-slot supply MAE 0.012 pp, non-dev buyer counts equal on 218/230, dev-sold-in-window equal on 225/230, serial snipers equal on 245/300 (MAE 0.5).

Honest limits

Not a prediction. In this sample, DANGER launches graduated MORE often (130/2,341 = 5.6%) than WARN (1.0%) or SAFE (1 of 1,305). Launches that take off attract snipers, bundles and early concentration, and the post-graduation holder check exists only for graduates. A verdict describes how a launch was run, not whether its price will rise or fall. Do not trade on it.
Snipers, bundles and funder links are heuristics over observed transactions; a wallet seen for the first time has no sniping history.
Batch features cover ~70-83% of launches; a launch with no trades in its window gets no features.
61 sample rows have a tape gap (tape_complete=false): counts there may be low.
The live tape keeps ~6 h; older launches are answered from batch features only.
The dev's current balance is not in this data (the paid token verdict reads live holders).
