What's inside NCRB

  1. Overview of NCRB Forestry Rights Tokenization

    Natural Capital ReBank (NCRB) provides a blockchain-based platform to tokenize Natural Capital assets, specifically forestry rights. The platform aims to solve liquidity, pricing opacity, and fragmented markets by offering instant settlement, real-time pricing via oracles, and fractional ownership using ERC-7943 uRWA tokens. Supported forestry asset types include timber harvesting rights, sustainable forestry management rights, REDD+ credits, and forest conservation easements.

  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 NCRB Water Asset Tokenization

    Natural Capital ReBank (NCRB) provides blockchain infrastructure to tokenize two primary water asset classes: Water Rights and Water Credits. The platform utilizes ERC-7943 uRWA tokenization to enable fractional ownership, instant settlement via on-chain transactions, transparent pricing through real-time oracles, and automated compliance via smart contract governance.

  4. 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.

  5. 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.

  6. 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.

  7. Overview of the ERC-7943 (uRWA) Standard

    ERC-7943 is the Universal Real-World Asset (uRWA) standard. It is a superset of ERC-20, meaning it maintains full backwards compatibility with all ERC-20 wallets, exchanges, and DeFi protocols while adding a minimal set of on-chain compliance hooks. This allows real-world assets (like carbon credits or biodiversity units) to enforce KYC/AML requirements, legal holds, and regulatory recovery directly at the token level.

  8. Overview of NCRB Agricultural Land Tokenization

    Natural Capital ReBank (NCRB) provides a blockchain platform to tokenize agricultural land, enabling fractional ownership, global liquidity, and transparent price discovery. The platform utilizes the ERC-7943 uRWA token standard to represent verified agricultural land titles/certificates on-chain, providing instant settlement and programmatic asset quality scoring.

  9. Overview of RWAToken and ERC-7943 Compliance

    RWAToken.sol is an ERC-20 token representing tokenized Real-World Assets. It implements the ERC-7943 (uRWA) standard, which adds on-chain compliance features including account allowlisting, token freezing, and regulatory enforcement transfers while maintaining ERC-20 compatibility. All standard ERC-20 transfers (transfer, transferFrom) are gated through an internal _update function that enforces these restrictions.

  10. 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.

  11. 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).

  12. Overview of NCRB Mining Rights Tokenization

    Natural Capital ReBank (NCRB) tokenizes mining rights (exploration, extraction, mineral rights, and royalty interests) using the ERC-7943 uRWA standard. The platform aims to provide instant settlement, transparent pricing via real-time oracles, fractional ownership, and automated compliance through smart contracts. It utilizes internationally recognized reserve reporting standards such as NI 43-101 (Canada), JORC (Australia), and S-K 1300 (US) to verify asset quality.
