DeFarm: Turn Farm Assets into Liquidity

SCF #40

$90.0K

Build

Awarded

DeFarm transforms verified agricultural data into digital assets anchored on Stellar, creating the trusted foundation needed for real-world finance.

Products & Services

DeFarm is a production platform that creates traceability tokens, digital passports proving the identity and history of every farm asset.
Each token links verified events (vaccinations, inspections, certifications) to a transparent record anchored on Stellar.

This grant will:

Build an open CLI & SDK so existing agricultural systems (ERPs, certification tools, government registries) can anchor and verify data directly on Stellar.
Extend Soroban smart contracts to manage circuit governance and privacy-preserving disclosures.
Deploy a community framework and miniapp tools, allowing developers to build RWA, DeFi, insurance, and carbon applications on verified data.

Using Stellar as the distributed registry ensures low-cost, auditable, and programmable proofs of asset identity (the prerequisite for real-world financial products).

Success Criteria

User Adoption & Traction: 20+ producers and 3 associations connected; 200 000 animals registered; 70% annual renewal rate.
Platform Functionality: verification within 48 h (60% faster than legacy methods); 95%+ environmental data accuracy; 100% tokens anchored on Stellar.
Financial Ecosystem: 3+ financial partners using data for credit or insurance; 10+ service requests facilitated; 30% reduction in due-diligence costs.
Stellar Ecosystem: new asset class for agricultural traceability; two reusable libraries (CLI/SDK modules); blueprint for tokenization of physical assets across sectors.

Go-To-Market Plan

Existing contracts with producers provide a ready pipeline for on-chain onboarding.
Open CLI/SDK and miniapp framework invite ecosystem developers and financial partners to build on verified data.
Expansion from Brazil and Portugal’s beef sector to other proteins (eg: swine) and crops through current partners.
Initial integrations with 3 ERPs and 2 financial institutions planned post-grant to demonstrate real-world scalability.

Traction Evidence

100 000 head of cattle under contract, with events already being anchored on Stellar testnet:
- Contract 1
- Contract 2
Live backend + web platform handling item and event registration.
Two pilot integrations validated with external systems.
Awarded $15 000 SCF Kickstart.
Technical paper “The Circuit Model” published describing the verifiable data architecture (link)

Tranche 1 (Deliverable Roadmap) - MVP

Core CLI/SDK with authentication, workspace management, circuit operations, and item/event tracking.
Focus on fundamental data sovereignty and simple collaboration features.

How to Measure Completion

Authentication (login, logout, whoami, refresh)
Workspace management (init, status, reset, config)
Circuit operations (list, show, join, members)
Item operations (new, list, show, update)
Event operations (add, list, show, update)
CLI/SDK integrated with Core API
Package installable + documentation available
Two external farm-management systems integrated (whitelisted partners with proper privacy strategy)

Estimated Completion: Month 3
Budget: $24 000

Lead Developer (3 mo): $14 000
Backend Developer (2 mo): $8 000
Testing & Docs: $2 000
Note: legacy-system integration requires specialists due to poor documentation.
Impact: foundation for all future integrations and financial applications.

Tranche 2 (Deliverable Roadmap) - Testnet

Brief Description
Add selective disclosure, receipts, and first Stellar integration — deployed on testnet.

How to Measure Completion

disclose command with privacy presets
Receipt system (receipts list/show)
Enhanced item & event management (update, delete, vaccination/movement events)
Circuit governance smart contract on Stellar testnet
Proof-of-concept tokenization of agricultural assets
Web dashboard for non-technical users
Public API documentation

Estimated Completion: Month 4
Budget: $36 000

Lead Developer (2 mo): $20 000
Stellar Integration Dev (1.5 mo): $9 000
Frontend Dev (1 mo): $4 000
Infrastructure: $3 000
Impact: makes traceability tokens operational on Stellar testnet and connects verified data with the ecosystem.

Tranche 3 (Deliverable Roadmap) - Mainnet

Brief Description
Production deployment on Stellar mainnet with miniapp framework and connected partnerships.
Builds infrastructure that accelerates integration and gives the community tools to create on top of traceability tokens.

How to Measure Completion

Platform live on Stellar mainnet
Miniapp framework released
≥1 partner (e.g., government agency or certifier) connected
Public developer documentation for building on DeFarm
Monitoring & support infrastructure in place
Example miniapps (asset tokenization, basic marketplace)
Performance validated with 1 000+ items across 10+ circuits

Estimated Completion: Month 6
Budget: $30 000

Lead Developer (2 mo): $18 000
DevOps & Production Setup: $6 000
Partnership Integration: $4 000
Docs & Community Tools: $2 000
Impact: makes DeFarm fully operational on Stellar mainnet and opens a community framework for building RWA and DeFi products on verified agricultural data.
