The BCGOLD
Index Token
The world's first liquid, on-chain index of verified blue carbon credits. Each token is backed by real retired Verra VCS credits from multiple verified mangrove restoration projects.
Liquid Nature.
On-Chain Proof.
Until now, owning carbon credits meant holding illiquid registry positions with PDFs as proof. The BCGOLD Index Token changes that — it's a fungible ERC-20 token that represents a diversified, audited, on-chain position across multiple blue carbon projects.
The pool aggregates retired Verra VCS credits from verified mangrove projects. When you hold BCGOLD, you hold a proportional share of that pool — and the pool ratio is always publicly visible.
This makes blue carbon accessible to individuals, brands, DAOs, and institutions — without needing to manage individual project positions or navigate the Verra registry directly.
Diversified Across Projects
The pool holds credits from multiple verified mangrove projects across different geographies, reducing single-project risk.
Backed by Real Retired Credits
Every token in circulation is backed by credits already retired on the Verra registry. No fractional reserve. No unsupported minting.
Composition Fully Transparent
Pool ratio snapshots are published on every composition change. Anyone can see exactly what backs each token at any moment.
Community Governed
Token holders vote on pool decisions — which projects to admit, ratio adjustments, and platform parameters. Governance weight = token balance.
From Contribution to Token
The path from contributor to BCGOLD token holder has five on-chain steps, each with a proof at every stage.
Contribute to a Tranche
You contribute to a funding tranche for a specific mangrove project. Funds go directly to project developers for restoration work.
Instrument types: Grant, Revenue Share, Debt. Your contribution is recorded in the BCGReceipt contract.
Receive a Receipt → Claim a Pack
Your contribution issues a Regeneration Receipt. After the project's first Verra audit, you claim your BCGPack — a hectare-denominated position.
BCGPack is an ERC-1155 token representing your fractional hectare entitlement after audit verification.
Credits Retired on Verra
When audit milestones are met, BCG retires verified credits on the Verra registry. Retirement is permanently recorded with beneficiary attribution.
Each retirement links to a Verra serial number, beneficiary name, and Arbitrum transaction hash.
Pack Deposited into Pool
You deposit your BCGPack into the BCG pool. The pool composition ratio is updated and your pack is accounted for in the aggregate.
Pool ratio snapshots are published publicly. The BCGPool contract manages all deposits and ratio tracking.
Receive BCGOLD Index Token
The BCGIndex contract mints BCGOLD tokens proportional to your pool deposit. You now hold a fungible, transferable position in the diversified pool.
BCGOLD is an ERC-20 token on Arbitrum. Token balance = governance weight = pool position.
How the Pool Works
Ratio-Based Composition
The pool tracks the ratio of each project's packs to total pool size. Ratios update on every deposit and are published as public snapshots.
Multi-Project Diversification
The pool accepts packs from multiple verified projects. This diversifies geography, methodology, and audit timelines — reducing concentration risk.
Governance-Controlled Admissions
New projects enter the pool through governance votes. Token holders decide which projects meet quality thresholds — preventing greenwashing at the pool level.
