Carbon Vault is a decentralized sustainability platform that bridges carbon credit analytics, zero-knowledge verification, and DeFi incentives.
Carbon Vault is a decentralized platform that bridges carbon analytics, verification, and trading through blockchain technology. It provides a transparent ecosystem where organizations, data providers, and validators collaborate to track, verify, and trade carbon value tokens (CVTs) with full trust and traceability.
Built on smart contracts and zero-knowledge proof mechanisms, Carbon Vault transforms traditional carbon tracking into a real-time, auditable, and data-driven system—ensuring environmental accountability without compromising privacy.
Smart Contracts Layer
Automates issuance, staking, and trading of CVTs.
Handles validator rewards, emissions data submissions, and carbon yield distribution.
Ensures tamper-proof verification through immutable records.
Data Analytics & Verification
Aggregates environmental data from IoT sensors, satellite feeds, and certified partners.
Uses validators to verify authenticity and generate cryptographic proofs.
Supports ZK-compliance checks for privacy-preserving validation.
Carbon Marketplace
Enables companies to buy and sell CVTs backed by verified carbon reduction data.
Integrates a dynamic pricing model driven by supply-demand analytics and validator activity.
Promotes transparency by displaying source, proof, and yield of every trade.
Staking & Yield Dashboard
Corporate buyers can stake CVTs for long-term sustainability commitments.
Validators earn rewards for accurate data validation and proof submission.
Real-time dashboard visualizes holdings, yield rates, and proof verification status.
Wallet Integration
Seamless onboarding with MetaMask or Mantle SDK.
Users interact directly with smart contracts without centralized intermediaries.
Carbon Vault aims to make carbon transparency accessible, verifiable, and economically rewarding.
By merging decentralized finance (DeFi) principles with climate analytics, it creates a sustainable bridge between environmental data integrity and financial incentive — empowering global climate accountability.
