Cosmos application chain that issues ecological credits under its own registry and tracks retirement as a distinct on-ledger balance. Strongest on retirement finality at the registry (9/10): Regen Ledger records retired credits as a balance separate from tradable and cancelled credits on the same ledger that issues them; batch C01-001-20150101-20151231-001 shows tradable 0, retired 20 and cancelled 0 through a public endpoint anyone can query. Weakest on vintage and methodology disclosure (7/10): Each Regen batch id carries its vintage window on the ledger, but the methodology sits in class metadata that takes a separate lookup; for class C06 it resolves to the Ecometric soil organic carbon methodology, version 1.1. Published price: No per-tonne price is published on registry.regen.network; its front page still carries only that "100,000 Ecometric ecocredits have already been sold". The Regen Ledger's own marketplace module publishes ask prices per credit.
Tokenised Carbon Credits
Tokenised Carbon Credits evaluated across traceable registry serials, retirement finality at the registry, vintage and methodology disclosure, and price against comparable credits.
Ranked here: tokenised carbon credits, credits held as tokens that can be bought and retired, for a reader who needs a retirement a registry will actually recognise. Not ranked here: carbon credits that have not been tokenised, and tokens that do not represent a carbon credit.

What matters most before choosing in this category
Weighted on whether a token traces to a registry serial you can check (32), whether retirement is final at the registry rather than a burn plus a promise (26), what the vintage and methodology actually are (22), and how the price compares to the same credit bought off chain (20). Serial traceability leads because without it nothing else is verifiable — and it is where the category is weakest: every provider here except Carbonmark and Regen asks the buyer to trust prose over a reproducible read. The one making the strongest claim, that "project, vintage, serial numbers, and other details" are written on chain, publishes no contract addresses at all, so the claim cannot be tested; its most recent dated deployment announcement is 21 August 2023.
