Stellar Stream Hive API + Docs

A Rust/Axum REST API that indexes payment-stream activity on Stellar, plus the documentation site for the whole Stellar Stream Hive platform (contracts + API

• web app).

Stellar Stream Hive is a payment-streaming platform built on Stellar and Soroban: a sender locks funds once and a recipient's claim on them vests linearly over time, ledger by ledger, rather than arriving as a single lump-sum transfer. See Getting Started for what that means in practice, and Streaming Math for the exact accrual formula, derived from first principles with a worked example.

Repositories

Stellar Stream Hive is split across three repositories:

Repo	What it is
stellar-stream-hive-api (this repo)	The indexer API (api/) and documentation site (docs/).
stellar-stream-hive-contract	The Soroban smart contracts: Stream, Vault, Registry.
stellar-stream-hive-frontend	The web app (Freighter wallet integration, stream creation/management UI).

This repository's layout

api/    Rust + Axum REST API + Horizon-polling indexer  (maintainer-only, see CONTRIBUTING.md)
docs/   Next.js 14 + TypeScript + Tailwind + MDX documentation site (open to contributions)

api/

Polls Horizon every 10 seconds, decodes Soroban contract events emitted by the Stream contract, and serves the resulting index over a small REST API (GET /streams, /streams/:id, /senders/:address, /recipients/:address, /stats). No database -- everything lives in memory for v1. See api/README.md for how to run it, environment variables, and the full architecture breakdown.

cd api
cargo run

docs/

This documentation site itself -- covers the contracts, the API, the web app, and how to integrate with the platform. Built with Next.js 14 (app router), TypeScript, Tailwind CSS, and MDX.

cd docs
npm install
npm run dev

Contributing

Read CONTRIBUTING.md before opening a pull request. In short: docs/ is open to contributions, api/ is maintainer-only, and PRs touching api/ will be closed without review.

Status

The contracts (stellar-stream-hive-contract) have not been deployed to any network yet. The API and docs in this repository are built and ready, but STREAM_CONTRACT_ID is an explicit placeholder until a real deployment exists -- see Getting Started: deployed contract addresses. Nothing in this repository fabricates a real contract address anywhere.
