Real-World Use Cases
Notareum in action
From everyday transactions to enterprise operations, the .nota format brings verification and human readability to every interaction with a blockchain.
Secure Payroll
A DAO treasurer creates .nota files for each contributor's wallet. Verified addresses with human-readable names eliminate the risk of sending funds to the wrong address during bulk payroll.
NFT Provenance
An artist signs their collection contract as a .nota file and shares it on social media. Collectors verify the contract is authentic before minting, preventing fake collection scams.
Cross-Chain Bridging
A user creates a .nota file containing their addresses on Ethereum and Solana. The bridge protocol reads both addresses from a single file, reducing errors in cross-chain transfers.
Institutional Custody
A fund manager shares .nota files with institutional-level verification (KYC-linked) with auditors and regulators. Each file contains the wallet address, verification proof, and compliance metadata.
01
Send your address as a verifiable .nota file instead of a raw hex string. The recipient sees your name, chain, and verification status before sending.
Sharing Wallet Addresses
02
Create a payment request with amount, currency, and recipient verification baked in. Like a QR code, but portable, verifiable, and tamper-proof.
Payment Requests
03
Get a cryptographic receipt for every transaction. Shareable, verifiable, and permanently yours. Proof of payment that actually means something.
Transaction Receipts
04
Send payment instructions to family abroad with built-in verification. No more "did I use the right address?" No more hoping the money arrives.
