The problem

Seaweed farmers in Tawi-Tawi often have little visibility into fair market prices and little ability to prove where their harvest went once it leaves their hands. That makes it hard to negotiate fairly and hard for buyers and exporters to verify the origin and handling of what they're purchasing.

How Agal works

One mobile app serves three roles — Farmer, Supplier/Aggregator, and Buyer/Exporter — each with the experience that role actually needs.

• Farmers log harvests and handoffs fully offline; everything syncs automatically once a connection is available, and nothing is ever lost or overwritten.
• Suppliers/Aggregators see incoming batches, confirm receipt, and post transparent prices.
• Buyers/Exporters verify a batch's full history before purchasing and record the transaction.

A tamper-evident chain of custody

Every step a batch takes — harvested, dried, transferred, sold, exported — is recorded as an event and hashed onto a public blockchain ledger. No farm or business data is ever stored on-chain, only a cryptographic fingerprint of each event, so anyone can independently confirm a batch's recorded history hasn't been altered after the fact.

Why Tawi-Tawi

Tawi-Tawi is one of the Philippines' major seaweed-farming provinces, with a supply chain that runs through many small-scale farmers before reaching aggregators and exporters. That length and fragmentation is exactly where price information gets lost and where it becomes hard to trace a shipment back to how — and by whom — it was actually produced.
