Own. Encrypt. Share. Control.
The next generation of secure, decentralized file storage and sharing.
Live: blockroll-gold.vercel.app — try the Stellar File Notary directly.
BlockRoll uses Stellar for two real, working features (not just a payment button), both client-side signed with Freighter - no backend, no custody.

Freighter wallet connects (requestAccess)

Browser builds a Payment operation (USDC, Circle's testnet issuer)

Freighter prompts the user to sign - private key never leaves the wallet

Signed transaction submitted to Horizon → Stellar Testnet ledger

Checkout page links the tx hash on Stellar Expert
Code: new-frontend/src/lib/stellar/payment.ts, StellarPayButton.tsx.
2. Stellar File Notary (try it live)
A free, standalone tool for proving a file existed, unmodified, at a point in time - without ever uploading the file anywhere.
File selected in browser
│
▼
SHA-256 hash computed locally (Web Crypto API) - file itself never leaves the device
│
▼
Hash written into a ManageData operation (key: "blockroll_notary")
│
▼
Freighter signs, transaction submitted to Horizon → Stellar Testnet ledger
│
▼
Anyone can later re-hash the same file and compare it against that transaction
to verify it is byte-for-byte unchanged
Code: new-frontend/src/lib/stellar/notary.ts, new-frontend/src/lib/stellar/hash.ts, /notary page.
Currently running on Stellar Testnet; see new-frontend/.env.example for configuration, and open issues for what's next (XLM payments, batch notarization, tests).
Using black, silver, and white gradients with glassmorphism and minimal shadows gives BlockRoll that luxury tech vibe, like Apple x Web3.
- ✅ Stellar-native payments & notarization - wallet-signed, non-custodial, verifiable on a public ledger
- ✅ Non-custodial encrypted storage - files are encrypted client-side; BlockRoll never holds the keys
- ✅ Share by wallet address, with expiry dates and revocable access
- ✅ Bank-level security on the backend - see below
