The marketing site reads live status from mainnet via /api/protocol/activity and shows it on the homepage #on-chain section.

Instructions

| Instruction | Purpose | |-------------|---------| | initialize_config | One-time: crank authority, mint, min balance (250k tokens), treasury | | sweep_treasury | Crank moves SOL from treasury PDA → swap wallet | | start_epoch | Commit merkle root + hourly pick attestation | | fund_epoch_vault | Deposit bought tokens into epoch vault | | claim | Holder proves merkle allocation and receives tokens | | set_paused | Authority emergency pause |

PDAs (after `init-config`)

| Account | Seeds | |---------|--------| | Config | ["config"] | | Treasury | ["treasury", pumpend_mint] | | Epoch | ["epoch", epoch_id_u64_le] | | Claim status | ["claimed", epoch_id, claimant] |

Treasury and config addresses depend on your $PUMPEND mint. They appear on the site once config is initialized.
