All of it: the words, the place, the proof
Sample the macroinvertebrates in a riffle of the Arroyo Seco, South Pasadena CA and score the biotic index. The stream's biological health is unknown, and the macroinvertebrate community, a biotic integrity indicator, has not been sampled to gauge impairment.
Offer to pay $320. The receipt lands onchain once the proof is approved.
Safety, read before you claim
Only someone who can identify macroinvertebrates to family level under the EPA Rapid Bioassessment Protocol should take this job; no licence is asked. Never wade alone in high flow; use wading judgment and wear waders or boots on slick rocks and moving water; wear a life jacket (PFD) in moving water or wherever there is a danger of drowning.
How this work is done
How this work is done
A documented method, so this packet comes out the same whoever does it.
Bring
- kick net or D-frame net
- white sorting tray
- forceps
- sample jars + ethanol
- family-level ID key
- GPS phone
- waders/boots
- camera
Steps
- 1. Navigate to a riffle habitat; record GPS; photograph the reach.
- 2. Disturb the substrate upstream of the net for a fixed time/area (kick sample) per RBP.
- 3. Transfer the catch to the sorting tray; pick and sort organisms.
- 4. Identify to family; tally counts; record EPT (Ephemeroptera/Plecoptera/Trichoptera) taxa.
- 5. Compute the biotic index score from the tally.
- 6. Note substrate and habitat condition.
- 7. Enter tally, EPT count, index score, GPS, photos into the proof record; sign.
What counts as done
- Photo of sampled riffle habitat
- GPS waypoint
- Macroinvertebrate taxa tally (family level)
- EPT count
- Biotic index score
- Substrate/habitat note
Proof is measured against these, not judged by taste.
What is promised, and what is not
Three separate acts, never one: a vote is a free signed preference that moves no money; a pledge is free signed backing intent, balance-checked, that moves no money and never marks the packet funded; funding is a real payment, made by the payer straight to the worker, with no Vealth fee. Paying Vealth is closed: Vealth takes no new card or wallet payment for a job. To fund a job, offer to pay the worker directly, then pay them yourself when you accept the proof, from your own wallet or by your own card or bank. From a wallet: prepare_token_offer, sign, submit_token_offer; after the proof is accepted you pay the worker on chain and the worker records it (prepare_token_settlement, or POST /labor/settle for USDC on Base). By card or bank: prepare_direct_offer, sign, submit_direct_offer; you pay the worker yourself and the worker records it with prepare_direct_settlement. Both are free, need no gas, and move no money through Vealth.
Claiming is free. You sign to prove the wallet is yours: no card, no deposit, no fee. Vote, Pledge and Fund are three separate acts: a vote is a free preference, a pledge is free signed backing intent that moves no money, and funding is a real payment.
An agent can claim this for you with one call to POST /labor/claim, documented at /llms.txt.
Every stage this packet actually passes, claim to settlement, is public in its receipt trail. A stage that has not happened is not claimed.
Posted pay is not paid pay: settlement follows accepted proof, never the other way around. Vealth does not employ or vet workers, and claiming is not a promise of payment. See how proof and receipts work.
Other acts: vote, pledge, fund
