Decentralized ride-sharing on a custom blockchain

Clutch Protocol is an open-source stack for on-chain ride operations: apps use a GraphQL Hub API and JavaScript SDK, sign transactions client-side, and settle rides on a Rust blockchain with Aura consensus.

Try the network

Use the public stage testnet — no install required

Quick start

  1. Open app-stage.clutchprotocol.io
  2. Choose passenger or driver and generate a wallet
  3. Request test CLT from the built-in faucet
  4. As passenger: request a ride on the map. As driver: view requests and submit an offer
Open stage demo

Testnet only — not production. Wallets and keys are for experimentation.

Stage endpoints

What exists today

Built for riders, drivers, and developers — alpha quality

CLT economics

Drivers keep most of each fare. Referrers earn up to 4% (default 2%+2%) on RidePay. Validators earn a fixed block reward (50 CLT/block), separate from rides.

On-chain payments

Passengers pay drivers in CLT via RidePay transactions. Partial payments are supported until the fare is covered.

Transparent and secure

Private keys stay on the client. Every ride step is a signed transaction recorded on-chain and auditable.

Developer tools

clutch-hub-sdk-js on npm, GraphQL Hub API, WebSocket subscriptions, and docs at docs.clutchprotocol.io.

Multi-node testnet

Aura consensus with multiple validator nodes on stage. Run the full stack locally with clutch-deploy.

Governance (planned)

Community DAO voting is on the roadmap. It is not implemented in the current codebase.

Stack

Open-source components you can run, read, and contribute to

Clutch Node

Blockchain core — Aura consensus, custom RLP transactions, WebSocket JSON-RPC. Rust.

Clutch Hub API

GraphQL bridge, wallet JWT auth, testnet faucet, and poll-based subscriptions. Rust.

Clutch Hub SDK

JavaScript/TypeScript SDK for signing, queries, and subscriptions. Published on npm.

Demo App

Reference React app with passenger and driver flows, map UI, and live updates.

Clutch Explorer

Block indexer, REST API, and web UI for blocks, transactions, and accounts.

Clutch Deploy

Docker Compose for nodes, API, demo, explorer, and monitoring — local or stage.

CLT economics

Implemented on-chain in clutch-node (alpha)

Example: 10 CLT ride (one RidePay, both referrers)

Driver 8 CLT
Request referrer 1 CLT (2%)
Offer referrer 1 CLT (2%)

Referrer fees apply per RidePay installment (configurable on the node). Validators earn a fixed block reward (default 50 CLT/block), not a share of ride fares. Details at docs.clutchprotocol.io.
