Controlled mainnet: settlement uses real USDG on Robinhood Chain and admin actions are governed by a 2-of-3 multisig. An independent security audit and registry-attestation provider are not live yet. Do not treat credits here as independently verified real-world emissions reductions.

Why Carbonized?

Carbonized explores onchain transparency, retirement records and liquidity for carbon markets. It is early-stage software.

Onchain credit records

Credits are minted as NFTs by an authorized issuer role, with project metadata, a serial number and a proof hash recorded onchain. Verification is currently performed by the admin/issuer; automated oracle verification is not live yet. NFTs can be wrapped into fungible ERC-20 pool tokens for trading.

Order book

A fixed-price order book settled onchain in USDG. The trading fee is currently 0.25%, and the admin can change it within a cap set in the contract.

Auctions

Discover fair prices for large or rare credit batches through transparent onchain auctions.

Portfolio & company tracking

See holdings, retirements and onchain activity per wallet, and let companies register and record self-reported emissions next to their retirements. There is no integration with the national ETS or CCER registries today.

CARB utility (coming)

CARB is a planned utility token and is not launched yet. Planned utilities only: reduced marketplace trading fees by staking tier (a discount on the fee, never on the price), an issuer bond for the bond-based issuer path, and parameter governance by token holders. No revenue share, no staking rewards, no returns, and no price or allocation commitments. Subject to legal review and independent audit. Not investment advice or an offer.

Transparent records

Issuance, trades and retirements are recorded on a public chain, so buyers can inspect the history of a credit.

For buyers

Unified liquidity

One market with an order book and auctions instead of fragmented venues.

For traders

Retirement certificates

Retire credits onchain and share a certificate that anyone can re-verify from the transaction hash. Emissions figures are self-reported.

For companies

Open to extension

Designed with carbon markets such as the China national ETS and CCER in mind; no registry integration exists yet.
