# AquaChain

> CosmWasm water-stewardship demo on Osmosis: nine modules for sensors, wells, utilities, bounties, credits, governance, and x402 agent field ops. Part of [InterINNL](https://interinnl.interchouette.net/).

## Demo home

- [AquaChain home](https://interinnl.interchouette.net/aquachain/): module grid and how-it-works overview
- [Contact](https://interinnl.interchouette.net/aquachain/contact): email the team or use the WebMCP contact form

## Modules

- [Citizen Science](https://interinnl.interchouette.net/aquachain/citizen-science): register sensors, submit readings, verifier rewards
- [Water Well Initiative](https://interinnl.interchouette.net/aquachain/water-well-initiative): crowdfund wells with milestone escrow
- [Water Utilities](https://interinnl.interchouette.net/aquachain/water-utilities): utility footprint certificates
- [Sustainable Actions](https://interinnl.interchouette.net/aquachain/sustainable-actions): community eco actions and rewards
- [Community Bounty](https://interinnl.interchouette.net/aquachain/community-bounty): escrowed sustainability bounties
- [Water Credits](https://interinnl.interchouette.net/aquachain/water-credits): internal conservation credit marketplace
- [Local DAO](https://interinnl.interchouette.net/aquachain/local-dao): community proposals and voting
- [Cross Exchange](https://interinnl.interchouette.net/aquachain/cross-exchange): fixed-rate partner ledger swaps
- [Agent Ops](https://interinnl.interchouette.net/aquachain/agent-ops): x402 USDC pay router for autonomous agents

## Agent gateway

Humans use Keplr on Osmosis (`osmo-test-5`). Autonomous agents pay USDC via HTTP 402 (x402 on Base Sepolia); the gateway verifies payment and relays drone measurements to citizen-science-registry.

- [Agent gateway repo](https://github.com/InterINNL/Aquachain-agent-gateway): Rust axum service (verify/settle, Osmosis relay)
- [Agent Ops module](https://interinnl.interchouette.net/aquachain/agent-ops): curl sample, gateway status panel when configured in prod
