Technology & Innovation
Sproutly and Carbify are not just planting trees; they're redefining how ecological impact is measured, verified, and tokenised through cutting-edge blockchain technology.
End-to-End Smart Contract Infrastructure
Our system runs on a robust, audited network of smart contracts, currently deployed on Polygon and soon expanding fully to Base. Each agroforestry system is represented by a unique NFTree, tied to:
Geo-coordinates
Tree species metadata
Carbon absorption data
Certification status via the Global Carbon Standard
Through our ERC-1155-based architecture, we link every kilogram of CO₂ to specific trees and their verified lifecycle, creating a transparent, traceable, and immutable carbon ledger.
Key contracts include:
NFTrees & Saplings (multiple batches deployed)
$aCO₂ tokens, 1:1 representation of real-world CO₂ absorption
CarbonCertificate generator provides verifiable, on-chain carbon offset documentation
$SEED and $CBY tokens, with burn logic, staking, and governance mechanisms
Bridge contracts, enabling cross-chain asset portability (Polygon <-> Ethereum <-> BASE)
Staking contracts, supporting single-sided and tree-linked staking (Batch 1–15)
Virtual land plot contracts, enabling reward multipliers and gamified impact
On-chain NFT marketplace, deployed and live
Unparalleled Traceability
Every NFTree links back to a satellite-monitored master tree of a 15- 25 m2 agroforestry system and is tracked in real-time for CO₂ capture. Each NFT contains:
Timestamped planting data
On-chain updates per growth audit (verified by 3rd party)
Region-specific performance benchmarks
Lifecycle-based CO₂ output projections (e.g., 25kg in year 1, 175+ kg/year after year 4)
Dynamic Growth via the Virtualiser
All NFTree evolution and metadata updates are managed through the Virtualiser, a smart contract layer that governs the visual and functional transformation of trees over time. Based on verified data such as CO₂ absorption, compost usage, and staking duration, the Virtualiser:
Updates NFTree visuals (e.g., sapling → mature tree)
Applies new traits and yield changes
Tracks evolution milestones (e.g., “Biodiversity Verified”)
This system bridges real-world ecological data with immersive Web3 mechanics, ensuring each NFTree becomes a living asset that grows in value, function, and visual richness as its real counterpart matures.
