Whitepaper
The technical paper behind voidcash - notes, keys, transactions, private gas, exits, the fee and the burn, and the security and privacy analysis.
The whitepaper describes voidcash as implemented: how notes, commitments and nullifiers work, how the privacy keys come from one wallet signature, what a transaction proves, how the note tree and note discovery work, how private transactions pay their own gas through ERC-4337, how exits and the large-exit hold work, receipts and payment links, and how the exit fee buys and burns VOID. It ends with the security arguments, an estimate of what an observer can still infer from public deposits and exits, and what a user has to trust.
The same material, page by page and kept in step with the code, is in these docs: start from Key concepts or Architecture.
Key concepts
The handful of ideas behind voidcash - notes, the vault, the privacy set, keys, registration, private gas, the exit fee and the burn, and VOID.
Get started
Connect your wallet, turn on privacy with one signature, and register your privacy key so that you can hold HYPE, and the tokens the vault lists, in private notes and receive private sends.
