Carbonized Is Live on Robinhood Chain Mainnet: A Controlled Beta, Explained

TL;DR: The Carbonized contracts are deployed on Robinhood Chain mainnet (chain id 4663) as a controlled beta. Settlement uses USDG, administration sits behind a 2-of-3 multisig, and the deployer account holds no roles. There is no independent audit yet, the marketplace has no verified inventory yet, and the CARB token has not launched. This post lists exactly what is true today so you do not have to guess.

This follows the testnet status report. That post described a prototype. This one describes the next step, and it is deliberately more cautious than the word "mainnet" suggests.

What is deployed

Nine contracts are live on Robinhood Chain mainnet, including the credit NFT, the wrapped credit token, the marketplace and the oracle contracts. You can inspect them on the explorer.

The payment token is the canonical USDG on this chain, not a mock. Real value moves through the marketplace, which is the reason the rest of this post is about limits rather than features.

Who controls it

Every privileged role is held by a Safe that needs two of three signers. The three signers are separate wallets controlled by people, not by a server. The account that deployed the contracts renounced all of its roles after setup, so it can no longer mint credits, pause contracts, set fees or grant access.

That reduces the single-key risk that the testnet had. It does not remove trust. Two signers can still act, and role changes have no timelock yet. The roadmap lists this as a known limitation.

What is gated

Marketplace access is KYC-gated onchain. An address that has not been approved cannot trade. The identity workflow that sets that eligibility is built and fails closed: until the provider is switched on, nobody is approved by accident.

Credits can only be created by an address holding an issuer role. At the time of writing no issuer has been authorised, so the marketplace is empty. That is intentional. An open marketplace with nothing real on it would only invite confusion.

What is not ready

I would rather you hear this from me:

• No independent audit. The contracts went through repeated internal reviews and a large test suite. That is not a professional audit and I will not call it one. A public rollout waits for an external report.
• No verified inventory. When the first listings appear, any placeholder entries will be labelled as demo inventory and will not claim to be verified credits.
• No registry attestation yet. Issuance quality depends on who holds the issuer role until external registry evidence is wired in.
• KYC is not live. The flow exists, the provider is not enabled.
• CARB has not launched. When it does, the contract address will be published on the site and verifiable on the explorer. Until then, any address you see attributed to CARB is not ours.

What happens next

The order matters more than the dates, and I am not publishing dates:

1. Authorise the first issuers and list clearly labelled inventory.
2. Turn on verification onboarding.
3. Complete and publish an independent security audit.
4. Add registry attestation.
5. Only then, open to the public and announce CARB.

The same sequence is on the roadmap page. If something there changes, the page changes first.

If you want to try it

The app is open for exploration at /app. Do not treat anything in it as an investment or as a verified emissions reduction. The credits are issued by an authorised issuer, not independently verified, and the contracts are unaudited.

If you find a problem, message @CarbonizedApp. A reported bug before the public rollout is worth far more than one found after it.
