PitchStable (PSL) collateralized by Trinidad Lake Asphalt, the world's largest natural asphalt deposit. Unlike mined commodities, the Pitch Lake refills continuously from Miocene-era geology below it — allowing tokenization without depletion, and setting a new ESG benchmark for commodity-backed digital assets.
PitchStable's environmental framework is engineered into the protocol itself — not added as disclosure. Every PSL in circulation is attested against these pillars on a monthly cadence.
Extraction at or below the lake's natural replenishment rate, with satellite-verified reserve integrity.
A national asset generating national returns. 64% of protocol profits flow to the Treasury of Trinidad and Tobago.
Multi-sig sovereign control with independent audit — transparency is a smart-contract invariant, not a report.
Traditional hard-asset reserves shrink with every unit tokenized. Trinidad Lake Asphalt behaves differently — geological inflow from the underlying oil fields exceeds the protocol's redemption cap, so the reserve's unit count grows over time.
Evaluated on the dimensions that matter to sustainability-mandated capital.

| Land disturbance | High | None beyond historical footprint |
| Water usage | Material (process + cooling) | Negligible |
| Tailings / waste | Significant | None |
| Custody | Private vault network | Sovereign (LATT, GoTT) |

First sovereign commodity-backed stablecoin under a national Virtual Assets Act — a new digital-infrastructure primitive.
Low-fee remittance rails for the Caribbean corridor, reducing costs for diaspora households.
Zero-depletion tokenization model respects the natural replenishment cycle and caps extraction accordingly.
Lower carbon intensity than mining-based reserves; avoided emissions vs. equivalent physical gold-backed issuance.
Protected 100-acre lake footprint under sovereign stewardship; biodiversity buffer zones maintained by LATT.
Regulated under TTSEC and Central Bank oversight. Multi-sig governance eliminates single-party capture.
Public-private JV between the Government of Trinidad and Tobago, Paxos, and the founder IP entity.
