Heirloom cycles limestone to pull CO2 from the air at the highest price in Frontier's whole portfolio.
$26.6M for 26,900 tonnes at $989/tonne, the priciest ton in any Frontier deal reviewed. Two different, both-honest 404 responders sit underneath it; no agent manifest either way.

The whole thing, plainly
Heirloom runs the priciest carbon-removal deal in Frontier's whole portfolio ($989/tonne), real and well-documented, but like most of this space, invisible to AI agents (no agent-discovery files). We sketched what provable field labor around a limestone site could look like, with every claim backed by a command you can re-run yourself, free. There's no ask, this is unsolicited desk research, not sent to Heirloom or Frontier.

The honest EWP intersection
What provable field labor looks like around a limestone DAC site
Heirloom does not need EcoWealth, nothing here claims a relationship, a gap in their operations, or a pitch. What follows is a concept: the bounded, photo+GPS+signature-proven field tasks EWP already prices per-packet, mapped onto the kind of physical plant/field work a limestone DAC operation runs day to day.
- Limestone tray handling. Spreading, turning, and loading limestone trays through the calcination/carbonation cycle, bounded, photo-logged tasks per batch.
- Sampling/monitoring support. Collecting material samples for the lab-verified carbonation-rate measurement that underlies the credit, the field task, not the lab analysis.
- Site restoration. Land recovery around a quarry or plant footprint once a section completes its cycle program, before/after photo proof.
Concept only, not a proposal to Heirloom, not a claim they lack this capability internally, and not evidence any EWP packet has ever been posted for this pathway. EWP's own proof (photo+GPS+one-time signature) is a task-completion layer, not a carbon-quantification or registry-issuance layer, durable-CDR crediting requires accredited MRV far heavier than a single field packet, as EcoWealth's own Carbonfuture recon (2026-07-16) already found in detail.
Straight about what this is: a passive-recon evidence page, not a partnership pitch or a claim of affiliation. Every factual claim on the linked brief carries a live, re-runnable command. EWP is a real, live protocol (Base mainnet contract, see the brief's footer link), nothing about Heirloom's operations, capability, or need for it is asserted here.
