# pumpdata.fun sample: one UTC day of pump.fun and PumpSwap trades, failed trades kept

One UTC day, **2026-10-15**, of every pump.fun bonding-curve trade and every PumpSwap trade in the pumpdata.fun
archive, with the trades that failed on chain kept beside the ones that landed. It's read from the chain's own
ledger, not an indexer's copy. Parquet, zstd, in shards of at most 500 MB. Not affiliated with pump.fun.

From [pumpdata.fun](https://pumpdata.fun/?utm_source=hf&utm_medium=listing&utm_campaign=open): every pump.fun trade, ever, sold by the call to trading agents (base rates, wallet records, launch records, replays) in USDC over x402. Free daily base rates: [/public/baserate.json](https://pumpdata.fun/public/baserate.json?utm_source=hf&utm_medium=listing&utm_campaign=open) and [/today](https://pumpdata.fun/today?utm_source=hf&utm_medium=listing&utm_campaign=open).

This sample is one day of it. The full history, any month or a custom cut is the bulk
tier: support@pumpdata.fun, or the quote form at [pumpdata.fun/pump-fun-bulk-data](https://pumpdata.fun/pump-fun-bulk-data?utm_source=hf&utm_medium=listing&utm_campaign=open).

## The UTC day

A row belongs to the day when its **block time** is in `[2026-10-15T00:00:00Z, 2026-10-16T00:00:00Z)`. Block time is the
Solana block's own timestamp (unix seconds), the same `ts` every pumpdata.fun call uses. For a failed trade it's the
time of the block the failed transaction landed in (the archive's `blocks.parquet`, by slot). Midnight
`00:00:00Z` is in. The next midnight is in the next day.

## Columns

Rows are ordered by `(ts, slot, idx, failed)` within and across shards (shard `00000` comes first).

| column | type | meaning |
|---|---|---|
| `block_time` | timestamp, UTC | block time, as a timestamp |
| `ts` | int64 | block time, unix seconds |
| `slot` | int64 | Solana slot |
| `idx` | int32 | the trade's position within its slot, as the archive orders it (landed and failed rows each have their own `idx`) |
| `venue` | string | `curve` (the pump.fun bonding curve) or `pumpswap` (a PumpSwap pool) |
| `venue_code` | string | the archive's raw venue code. Curve codes are `c`, `curve`, `bonding_curve` or `0`, and any other code is PumpSwap. The coverage table lists the codes present |
| `failed` | bool | `false`: the trade landed. `true`: the transaction tried a curve or PumpSwap trade, made it into a block and failed (`error` says why). Failed rows have no amounts and no reserves, only who tried what, the fee they paid and the error |
| `mint` | string | the token's mint address |
| `pool` | string | the PumpSwap pool address. Null on curve rows and on failed rows (the archive keeps no pool for a failed trade) |
| `migration_pool` | bool | PumpSwap landed rows only: `true` when `pool` is the coin's own pump.fun migration pool quoted in WSOL (its `migrate` and `pool` events, as pumpdata.fun's base rates count it), `false` for any other pool trading the mint (third-party pools, other quotes). Null on curve and failed rows |
| `wallet` | string | the trader: the trade's user, or the failed transaction's signer |
| `side` | string | `buy` or `sell` (of the token) |
| `sol_lamports` | int64 | SOL in the trade, lamports (1 SOL = 1e9). Null on failed rows |
| `token_amount` | int64 | tokens in the trade, base units (pump.fun tokens have 6 decimals). Null on failed rows |
| `r1`, `r2`, `r3` | float64 | reserves as the archive's parser stores them. Null on failed rows. **Curve:** `r1` is the SOL reserve (lamports) and `r2` the token reserve (base units), price in SOL per token = `(r1 / 1e9) / (r2 / 1e6)`. **PumpSwap:** `r1` is the base (token) reserve and `r2` the quote (WSOL, lamports) reserve before the trade, and `r3` is a quote-side amount pumpdata adds to the quote reserve when it prices a pool. Pool rows before about epoch 1030 carry no `r3`. |
| `fee_lamports` | int64 | failed rows only: the fee the failed transaction paid, lamports |
| `error` | string | failed rows only: the transaction's error as the runtime reported it |
| `epoch` | int32 | the archive epoch the row was read from |

## Reading it

```python
import duckdb
duckdb.sql("SELECT venue, failed, count(*) FROM 'data/*.parquet' GROUP BY ALL")
```

```python
import pandas as pd
df = pd.read_parquet("data/")  # pyarrow; block_time comes back tz-aware UTC
```
