App Developer Incentives
Build a ride-sharing app on Clutch and earn CLT when users complete rides on your deployment. The network pays referrer fees on each RidePay — there is no separate grants program or development treasury.
How app builders earn
When a passenger pays a driver via RidePay, the node splits each payment installment:
| Recipient | Share (default) | Source |
|---|---|---|
| Request referrer | 2% of installment | RideRequest.referrer |
| Offer referrer | 2% of installment | RideOffer.referrer |
| Driver | Remainder | Fare minus referrer fees |
Fees are credited in CLT on-chain. If the same wallet is referrer on both request and offer, it can receive up to 4% of each RidePay installment (with default node config).
Referrer fees use ceiling rounding (e.g. 2% of 3 CLT = 1 CLT).
When you get paid
Referrer fees are paid only on RidePay, not when a ride is requested or accepted.
- Passenger accepts an offer → full fare is debited from the passenger (
RideAcceptance). - Passenger sends one or more
RidePaytransactions → referrers and driver are credited from that installment. - If the trip is cancelled before full payment, unpaid fare is refunded to the passenger — no referrer fee on amounts never paid.
Your earnings scale with ride volume and fares on transactions where your wallet is the referrer.
Earnings example
Default config, 10 CLT fare, one full RidePay, both referrers set to your app wallet:
| Recipient | CLT |
|---|---|
| Your wallet (request referrer) | 1 |
| Your wallet (offer referrer) | 1 |
| Driver | 8 |
If you set the same address for both default_ride_request_referrer and default_ride_offer_referrer, you receive 2 CLT on this ride.
With no referrers configured, the driver receives the full installment and app builders earn nothing from that ride.
How to participate
1. Run your own Hub API
Referrer addresses are attached when the Hub API builds unsigned RideRequest and RideOffer transactions. Clients do not choose the referrer on the public Hub — it comes from your Hub config.
Set your CLT wallet in Hub API config:
# App-developer referrers injected by Hub API
default_ride_request_referrer = "0xYourClutchPublicKey"
default_ride_offer_referrer = "0xYourClutchPublicKey"
Use the same address on both sides to earn both fee streams, or use different addresses for request vs offer attribution.
2. Build your app with the SDK
Integrate clutch-hub-sdk-js for signing and GraphQL calls. Point the SDK at your Hub API URL, not only the public stage/demo Hub.
3. Deploy the stack
Use clutch-deploy to run nodes, your Hub API, and your app (Docker Compose). All rides through your Hub carry your referrer addresses.
4. Track earnings
Use Clutch Explorer or node RPC get_account_balance_effects to audit ReferrerRequestFee and ReferrerOfferFee credits to your wallet.
What you need
| Requirement | Purpose |
|---|---|
| CLT wallet (secp256k1 key pair) | Receive referrer payouts |
| Hub API deployment | Inject your referrer on ride txs |
| App (web/mobile) + SDK | User-facing ride flows |
| Connection to Clutch nodes | Submit signed transactions |
Important limits
Clutch is experimental. CLT on testnet has no fiat value. APIs and economics may change.
- Your Hub, your referrers — Earnings go to whoever owns the Hub config. Apps using someone else's shared Hub do not automatically get a share unless that operator sets your wallet as referrer.
- No per-app registry — There is no on-chain app ID or automatic revenue split across multiple third-party apps on one Hub today.
- No grants or dev fund — Referrer fees on rides are the only built-in app-builder revenue mechanism.
- Validators are separate — Block rewards (
block_reward_amount, default 50 CLT/block) go to validator block authors, not app developers.
Node-side fee percents
Referrer percentages are set on each node (must match across validators):
ride_request_referrer_fee_percent = 2
ride_offer_referrer_fee_percent = 2
