What's inside NCRB

  1. Overview of the Natural Capital Stablecoin (NCSC)

    The Natural Capital Stablecoin (NCSC) is a USD-pegged digital currency collateralized by independently certified environmental assets (natural capital) tokenized on the NCRB platform. Unlike fiat-backed or algorithmic stablecoins, NCSC is backed by a non-withdrawable on-chain treasury of RWA tokens. The total supply is programmatically maintained to equal the total USD market value of locked assets, with automatic mint/burn operations triggered if the peg deviates by more than 0.5%. While NCSC is freely tradeable on-chain, redemption for fiat currency is gated by a redemptionEnabled flag, which is set to false by default and requires regulatory approval by the contract administrator to enable.

  2. Overview of AccountManager roles and permissions

    The AccountManager.sol contract uses a role-based access control system to manage the KYC allowlist. There are three primary roles:

    • DEFAULT_ADMIN_ROLE: Held by the deployer or admin multisig; can grant or revoke all other roles.
    • ADMIN_ROLE: Held by Oracles or admins; allows removing accounts, granting/revoking account roles, setting max accounts per role, and performing upgrades.
    • ACCOUNT_MANAGER_ROLE: Held by Oracles or operations; allows adding, activating, suspending, and updating metadata for accounts.

  3. Overview of NCSC Stablecoin

    NCSC is an asset-backed stablecoin pegged 1:1 to the US Dollar ($1.00). Unlike fiat-backed stablecoins (like USDC) that rely on bank accounts, NCSC is collateralized by certified natural capital asset tokens (e.g., carbon credits, forestry rights, biodiversity credits) locked in a non-withdrawable on-chain smart contract (TreasuryAssetContract).

  4. Overview of NCRB Natural Capital Asset Classes

    The NCRB platform supports 10 natural capital asset classes. For each asset class, technical and market whitepapers are available covering market overviews, quality bands and pricing, token issuance criteria, quality scoring frameworks, token economics, and buyer workflows. The supported asset classes include Carbon Credits, Plastic Credits, Nitrogen Credits, Phosphorus Credits, Agricultural Land, Mining Rights, Water Rights & Credits, Renewable Energy Credits, Forestry Rights, and Biodiversity Credits.

  5. Overview of NCRB Biodiversity Credit Tokenization

    Natural Capital ReBank (NCRB) provides institutional-grade infrastructure to tokenize verified biodiversity credits. The platform utilizes blockchain technology to solve liquidity, pricing, and transparency issues in the $600 billion biodiversity credit market. Key features include instant settlement via on-chain transactions, transparent pricing through real-time oracles, fractional ownership using ERC-7943 uRWA tokens, and automated compliance via smart contracts.

  6. Overview of NCRB Phosphorus Credit Tokenization

    Natural Capital ReBank (NCRB) tokenizes Phosphorus Credits to enable transparent, on-chain trading of verified phosphorus reduction credits. The platform addresses liquidity, pricing opacity, and fragmented markets by providing instant settlement, real-time pricing via oracles, and automated compliance via smart contracts. It specifically targets the $60 billion market for phosphorus runoff reduction in North America and Europe.

  7. Overview of NCRB Marketplace Governance

    NCRB uses a 3-of-5 multi-signature governance model to review and approve certificate submissions before RWA tokens are minted. At least 3 out of 5 designated governance members must approve a proposal within a 7-day window, or the proposal expires automatically. All voting actions are recorded on-chain for public auditability.

  8. Overview of Biodiversity Credits in NCRB

    Biodiversity credits are verified units of biodiversity gain, representing measured improvements in the quality and extent of habitats for wildlife, plants, and ecosystems. They enable developers, corporations, and governments to offset biodiversity net loss resulting from construction, land use change, or agricultural intensification by purchasing verified gains created elsewhere.
