Prove every claim from origin to retirement.
Issue a credit or sustainability claim with its origin, governing rules, transfers, and retirement attached. Buyers can verify the record directly instead of borrowing confidence from paperwork.
The problem
“Trust us” cannot carry a market.
Carbon markets suffer from double-counting, opacity, and greenwashing, and the reason is structural: a buyer usually cannot independently verify what they purchased, where it came from, or whether it was already sold to somebody else.
So the market compensates with intermediaries, ratings, and periodic audits — all of which add cost and delay without ever closing the underlying gap, because they are checking paperwork rather than the thing itself.
How it works
Issue the claim. Trace each change. Retire it for good.
Issue on the ledger
The credit is created as an on-ledger record, tied to the project or activity that generated it and to the party issuing it.
Bind it to its rules
A smart contract defines what the credit represents, who may hold it, how it may transfer, and what retiring it requires.
Track every transfer
Each movement is recorded, so the chain from origin to current holder is complete and checkable by anyone entitled to look.
Record retirement
When the credit is used, retirement is written to the ledger. It cannot then be sold again, because the record says it is spent.
What it uses
What keeps the claim attached to evidence.
Provenance is a contract problem as much as a data problem: the claim, its rules, and its live evidence have to travel together.
