Milestone-gated disaster relief & donation protocol powered by Arbitrum Stylus (Rust WASM). Transparent fund releases enforced through verifiable on-chain audits.
### Overview
Truvial is an institutional-grade, milestone-gated disaster relief and charitable donation protocol powered by Arbitrum Stylus. It eliminates donation mismanagement and lack of transparency by ensuring funds are locked in an on-chain treasury and only disbursed when cryptographically verified milestones are completed.
### The Problem
- Lack of Transparency: Traditional charitable organizations provide little to no verifiable tracking of how funds are actually spent.
- High Overhead & Intermediary Fees: Cross-border aid often loses up to 15-30% in administrative and banking overhead.
- Unchecked Capital Allocation: Full lump-sum donations are distributed upfront with no recourse if aid milestones are never delivered.
### The Solution: Truvial
Truvial introduces programmable disaster relief funds:
1. Capital Vaulting: Donors contribute funds that remain locked in a trustless Treasury contract on Arbitrum Sepolia.
2. Milestone-Based Releases: Relief campaigns define discrete, verifiable phases (e.g., "Emergency Medical Kits Delivered", "Shelter Construction").
3. Auditor Multi-Sig Verification: Independent relief inspectors and auditors sign off on milestone completions on-chain before funds are released to the campaign organizers.
4. Donor Reclaim Mechanism: If a milestone fails verification or expires, unallocated funds can be refunded or redirected.
### Smart Contract Architecture (Arbitrum Stylus)
Truvial takes full advantage of Arbitrum Stylus (Rust WASM):
- *Treasury contracts/treasury):** Written in Rust stylus-sdk 0.6.1). Implements a high-efficiency memory and storage layout to manage deposits, donor tracking, and fund disbursements.
- *Distribution contracts/distribution):** Written in Rust. Enforces milestone status logic and interacts with the Treasury via Stylus cross-contract invocations sol_interface!).
- Gas & Compute Efficiency: Executing complex audit verification logic in Rust WASM dramatically reduces gas consumption compared to legacy EVM bytecode.
<p>During the Arbitrum Open House Singapore Online Buildathon, we designed, implemented, and deployed Truvial from the ground up:</p><p>1. <strong>Smart Contracts in Arbitrum Stylus:</strong></p><p> - Authored the core <code data-inline="true" spellcheck="false">Treasury</code> and <code data-inline="true" spellcheck="false">Distribution</code> smart contracts in Rust using <code data-inline="true" spellcheck="false">stylus-sdk 0.6.1</code>.</p><p> - Engineered cross-contract calling <code data-inline="true" spellcheck="false">sol_interface!</code>) between the distribution engine and the treasury vault.</p><p> - Compiled to optimized <code data-inline="true" spellcheck="false">wasm32-unknown-unknown</code> release targets.</p><p>2. <strong>Full-Stack dApp:</strong></p><p> - Developed a responsive Next.js frontend using Viem, Wagmi, and TanStack Query connected to Arbitrum Sepolia <code data-inline="true" spellcheck="false">421614</code>).</p><p> - Integrated a pure Arbitrum / EVM wallet flow (MetaMask, Rabby, Coinbase Wallet, Injected).</p><p> - Built 1-Click Instant Demo Profiles (Donor, Campaign Creator, Auditor) allowing judges to experience the full end-to-end lifecycle immediately.</p><p>3. <strong>Production CI/CD & Deployment:</strong></p><p> - Configured GitHub Actions CI/CD to compile Stylus Rust contracts and build/lint frontend on push.</p><p> - Deployed the live production dApp on Vercel at <a href="https://truvial.vercel.app">https://truvial.vercel.app</a>.</p><p></p>
<p>Truvial is currently bootstrapped and at the pre-seed / grant-seeking stage. </p><p>We are actively seeking non-dilutive ecosystem grants from the Arbitrum Foundation, as well as early-stage venture backing and incubator support to transition Truvial from a working buildathon MVP into a production-grade disaster relief protocol.</p><p>Our immediate fundraising objectives and capital allocation plan focus on:</p><p>1. Smart Contract Auditing: Conducting rigorous third-party formal verification and security audits on our Arbitrum Stylus Rust contracts.</p><p>2. NGO & Relief Pilot Programs: Partnering with regional humanitarian NGOs and emergency response agencies across Southeast Asia to pilot milestone-gated relief disbursements on Arbitrum One.</p><p>3. Liquidity & Fiat On-Ramps: Integrating institutional stablecoin liquidity and direct fiat-to-crypto on-ramps so non-web3 donors can seamlessly contribute.</p><p>4. Decentralized Auditor Network: Expanding the auditor verification framework into an incentivized, multi-signature auditor DAO for on-the-ground verification.</p><p>We welcome discussions with Arbitrum ecosystem mentors, grant committees, and strategic Web3 impact investors to bring transparent on-chain philanthropy to global disaster relief.</p><p></p>
