Transparency

Pumpend is built on a simple promise: you shouldn't have to trust us blindly.

On-chain program (mainnet)

Hourly distributions run through the Pumpend distributor program:

| | | |---|---| | Program ID | HiUgQPkZPLQKqRrmRz477ALGVe3Mhzyyx9YEhiUSowW4 | | Explorer | Solscan program account | | Live status | Homepage → On-chain activity |

Core flow:

start_epoch commits the merkle root and pick metadata for the prior UTC hour.
claim pays holders who prove their allocation against that root.
Treasury PDA receives Pump.fun creator fees via SharingConfig (configured at launch).

Full instruction list: On-chain program.

Verifiable epochs

Each hour the crank publishes a JSON artifact with:

Qualifying holder allocations and merkle proofs
Pick attestation (mint, volume, tx count, algorithm version)
On-chain transaction signatures (start_epoch, fund_epoch_vault, swap)

Anyone can cross-check Solscan transactions against the artifact. The site surfaces the latest epoch on the on-chain dashboard and on Claim.

Fee routing

Two knobs (both fixed at launch):

SharingConfig share_bps — % of creator fees to treasury PDA vs team wallet (immutable after setup).
Crank sweep % — % of treasury SOL swapped each hour (reserve kept for rent/gas).

Default: 60% treasury / 40% team.

Top pick attestation

The #1 coin uses volume_candidates_max_fees_v2: Dex PumpSwap discovery → top candidates by volume → Helius fee/quality scoring → winner among passers. Paid boost placements are excluded. Each epoch stores a pick attestation hash and on-chain picked_txns_h1 / picked_volume_h1_usd.

Details: The hourly top pick.

Verify yourself

Open Solscan and confirm program + recent transactions.
Compare on-chain activity treasury balance and epoch txs to your expectations.
On claim, verify your merkle proof matches the published epoch file.

We'd rather you verify than believe. Transparency is core to Pumpend—not an afterthought.
