Grant Proposal: RapidPrediction — Verifiable Resolution Evidence on Filecoin

# Grant Proposal: RapidPrediction — Verifiable Resolution Evidence on Filecoin

**Project Name:** RapidPrediction

**Proposal Category:** `Other` (consumer prediction-market dapp on FVM with Filecoin storage integration)

**Individual or Entity Name:** Individual — Kelvin White

**Proposer:** `RapidPrediction`

**Project Repo(s):** https://github.com/RapidPrediction/RapidPrediction (dual Apache-2.0/MIT licensing already adopted; grant-funded work will be published open-source under this dual license)

**Filecoin ecosystem affiliations:** None. No existing work relationships, investors, or beneficial owners connected to Protocol Labs, Filecoin Foundation, FFDW, or other Protocol Labs Network organizations.

**(Optional) Technical Sponsor:** N/A

**Do you agree to open source all work you do on behalf of this RFP under the MIT/Apache-2 dual-license?:** Yes.

### 1. What is your project and what problem does it solve? (max 100 words)

RapidPrediction is a live Polymarket-style prediction market running entirely on Filecoin: PRED (ERC-20) trades on FEVM mainnet, deposits use USDFC and native FIL, and users sign in with SIWE. Prediction markets have a trust problem — traders cannot independently verify why a market resolved the way it did. We solve it with Filecoin: daily on-chain anchors of our balance ledger and resolution Merkle roots, plus per-market evidence bundles (sources, price feeds, rule commitments) on IPFS via Lighthouse. This grant funds upgrading that evidence layer to provably-stored, fast-retrievable Filecoin services.

### 2. How is Filecoin used in this project?

The entire on-chain layer runs on Filecoin mainnet FEVM (chainId 314; identical deployments on Calibration for rehearsal), accessed via Glif public RPC using web3.py:

- **PRED ERC-20** (platform currency): `0x7De552a29dbd2a64313d0e8529bD4015cf8a9C64`
- **Soulbound achievement badges** (non-transferable): `0x7c995C32e0c46360FA3a84a4ec54361204a5978a`
- **Transparency anchor contract**: `0x70118d52a65D2FfF9b930791413c163Dd1D09dAb` — daily SHA-256 hash chain of the append-only balance ledger + Merkle root of all market resolutions
- **Deposits**: USDFC (Secured Finance) and native FIL via EIP-681 payment URIs; every user gets a custodial FEVM wallet on signup
- **Storage**: Lighthouse (IPFS) holds daily ledger snapshots and per-market resolution evidence bundles; CIDs are published on-chain in the anchors and surfaced in our API and UI
- **Auth**: Sign-In-With-Ethereum (EIP-4361) — one wallet signature creates a trade-capable account (MetaMask supported)

**On-chain activity growth:** every signup mints a custodial wallet, every deposit/withdrawal/badge claim and daily anchor is an FEVM transaction, and the grant work adds Filecoin Pay settlement flows (USDFC) for Warm Storage — recurring, verifiable on-chain activity tied to real product usage.

### 3. How will you improve your project with this grant? What steps will you take to meet this objective?

| Number | Grant Deliverable | Briefly describe how you will meet deliverable objectives | Timeframe (within 3 months) |
| :--- | :------ | :--- | :--- |
| 1. | Evidence bundles on PDP-backed Filecoin Warm Storage | Integrate the Synapse SDK (Node sidecar until the Python SDK ships): USDFC deposit into Filecoin Pay, Warm Storage operator approval, dataset creation, and per-market bundle upload with PieceCIDs stored alongside existing Lighthouse CIDs. Rehearse on Calibration, then ship to mainnet. | Weeks 1–6 |
| 2. | Filecoin Beam fast retrieval for all evidence artifacts | Serve evidence and snapshot links Beam-first (PieceCID) with Lighthouse gateway and ipfs.io fallbacks, so "verify it yourself" links load fast globally without a single-gateway bottleneck. | Weeks 4–8 |
| 3. | Public Developer API exposure + third-party verifier docs | Add evidence CIDs/PieceCIDs and anchor data to our public read-only API (`/api/v1/`), and publish step-by-step verification documentation so anyone can audit resolutions without trusting us. | Weeks 8–12 |
| 4. | Recorded demo + 3–6 month roadmap | Publish a recorded end-to-end demo (trade → resolution → on-chain evidence verification) and a forward roadmap with resource needs. | Week 12 |

### 4. What is the total amount of this grant request?

$10,000 — covering ~12 months of infrastructure (servers, Lighthouse storage, FIL gas float, Warm Storage/Filecoin Pay service budget) and the development work in the table above.

### 5. Adoption, Reach, and Growth Strategies

**Target audience:** (a) prediction-market traders — a mainstream crypto category proven by Polymarket on Ethereum/Polygon, which RapidPrediction brings to Filecoin with a verifiability feature those platforms lack; (b) web3 developers, via our public read-only Developer API and machine-readable docs (llms.txt).

**Current engagement:** the platform is live and open at rapidprediction.org with a mobile-first PWA, one-signature wallet signup (SIWE/MetaMask), automated breaking-news market creation every 15 minutes, and an AI market-analysis agent.

**Onboarding first 10/100 users:** frictionless wallet signup (one signature, no email, signup bonus) is the funnel; first 10 via direct outreach in Filecoin/prediction-market communities and this grant's public build-in-the-open updates; first 100 via SEO topic hubs (breaking-news and calendar pages), embeddable market widgets for external sites, referral rewards, and creator milestone bonuses that pay users for making markets others trade.

### 6. If accepted, do you agree to share monthly project updates in this Github Issue until the project described here is complete?

Yes.

### 7. Does your proposal comply with our Community Code of Conduct?

Yes — reviewed and in compliance.

Start by reviewing the RapidPrediction repository and the four listed grant deliverables, especially the Synapse SDK sidecar, Filecoin Warm Storage, Beam retrieval, and the /api/v1/ developer API. Done means the proposal's stated integrations, public verifier documentation, recorded demo, and roadmap are delivered; no specific files or tests are identified in this issue.
