ParcelProof is a Solana-native evidence registry for real-world assets. It is designed for operators who need a portable, timestamped way to prove that inspections, insurance, title checks, and other controls happened without putting private documents on-chain.
RWA projects often tokenize the asset before they solve the evidence problem. A token can point to a warehouse, invoice, vehicle, or energy project, but investors and counterparties still need to know: who checked it, when, what was checked, and whether the claim is stale. ParcelProof turns those answers into a composable passport.
Dashboard: Open ParcelProof
The hosted interface is a safe fixture-data demo. It does not request a wallet connection or submit transactions. The Anchor/Rust program is included for local Solana devnet work.
- A polished dashboard for an industrial-property asset passport
- Evidence ledger with source, timestamp, digest, and verification state
- Network view showing independent attestation providers
- Solana Anchor program in Rust with PDA-backed asset and attestation accounts
- Devnet-oriented configuration and a clear security boundary
The Anchor program stores hashes and metadata pointers, not private inspection files. An AssetPassport PDA is derived from passport, owner, and asset identifier. Each Attestation PDA is derived from attestation, passport, provider, and nonce. Providers sign their own records; the asset owner can pause a passport but cannot rewrite historical attestations.
The current UI uses fixture data so it is safe to demo without a wallet or funded account. The program is structured for Solana devnet deployment after installing Rust, Solana CLI, and Anchor.
anchor build
anchor test
solana config set --url devnet
anchor deploynpm install
npm run dev
npm run build- Add compressed document commitments and Arweave/IPFS pointer support
- Add provider reputation based on expired or disputed attestations
- Add SPL-token gated access for sensitive evidence metadata
- Add a permissioned issuer registry with multisig administration
This is a devnet-ready technical prototype, not a title system, investment product, or legal verification service. All sample asset information is fictional.
