The Problem & Our Solution
The problem: crypto has no privacy
Every public blockchain is a permanent, searchable record of your entire financial life. Anyone with your address can see:
- Exactly how much you hold — down to the cent, forever.
- Every counterparty — who paid you, who you paid, when, how often.
- Your full history — salary, savings, trades, donations, everything.
And it gets worse off-chain. The moment your wallet queries a normal RPC provider, that provider logs your IP address next to the addresses you care about — deanonymizing you even if the chain data alone couldn’t.
On-chain, you are a glass wallet. Everyone can see inside, and the record never forgets.
Existing “privacy” tools ask for hard trade-offs: hand funds to a custodial mixer (trust + regulatory risk), run complex expert tooling, or bridge to a niche privacy chain with no liquidity and no everyday apps.
The solution: privacy as the default
BlackVault makes privacy the normal way to use a wallet — no mixer, no expert setup, no leaving the ecosystem.
| The problem | BlackVault’s answer |
|---|---|
| Balances are public | Stealth addresses — funds land where only you can find them |
| Transfers link people | ERC-5564 breaks the sender↔receiver link on-chain |
| RPC leaks your IP | Same-origin proxies — no third party sees IP + address |
| Mixers require trust | Non-custodial, standard contracts, keys stay yours |
| Privacy tools are hard | One-tap private send, receive, and pay-by-name |
| Privacy chains are empty | Built on Robinhood Chain — retail distribution + real assets |
Why now
Three things line up for the first time:
- ERC-5564 stealth addresses are standardized with canonical singleton contracts — privacy without a custom mixer is finally practical.
- Robinhood Chain brings a mainstream, retail-scale distribution channel and tokenized real-world assets to an EVM L3 with sub-cent fees.
- Embedded wallets + passkeys removed the seed-phrase barrier — privacy can now ship inside an app anyone can use.
BlackVault is where these meet: consumer-grade privacy, on the chain with the biggest consumer funnel.
