intermediate work · Urban-agriculture plot, Mexico City (place-type), MX

Urban-agriculture heavy-metal screen (place-type).

Fund it for $320. Proof lands onchain when it's done.

$320 proposed

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash — recorded, and readable any time at vealth.net/labor/credit/(your wallet). You see which before you claim, never after.

The creator wallet. Its signature is what approves proof and settles the wage.

How this work is done

A documented method, so this packet comes out the same whoever does it.

Bring

  • trowel or auger
  • clean bucket + mixing tool
  • XRF analyzer or metals test kit
  • PID for volatiles (if petroleum in scope)
  • sample bags + labels
  • N95 dust mask
  • gloves + eye protection
  • GPS phone
  • camera

Steps

  1. 1. Navigate to the parcel; record GPS; sketch a >=5-point sampling grid.
  2. 2. Photograph each sampling point and any visible staining/fill/slag.
  3. 3. Collect 0-15 cm cores from >=5 points; combine and mix in the clean bucket; subsample.
  4. 4. Run XRF/test kit on the composite; record each metal in ppm.
  5. 5. If petroleum is in scope, log PID readings and any odor/staining.
  6. 6. Bag/label any lab subsample; complete chain-of-custody.
  7. 7. Enter all analytes with units, depth, GPS, photos, and site sketch into the proof record; sign.

What counts as done

  • Photos of 5 points
  • GPS waypoint
  • Composite Pb (ppm)
  • Other metals where screened
  • Depth 0-15cm + sketch

Proof is measured against these, not judged by taste.

The money and the proof

What is promised, and what is not.

Funding this work is a purchase or a vote, same act: you either want this done here, or you want the world to contain it. A vote is free and signed; funding starts at one cent and anything beyond the wage is recorded as a premium for the worker. Either way the money settles only on accepted proof. An agent can fund it in one x402 call: POST /nurture/fund {"workId":"WORK_1788157686813_co7z9tc","funderWallet":"0xYOU"}.

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.
