01 · The idea

You wouldn’t publish your bank statement.
Why publish your wallet?

Your money tells a story. You choose who gets to read it.

The proof is public.
The details are yours.

An Ethereum transfer prints the sender, the recipient and the amount, forever. A private send prints a proof that the math checks out, and nothing else.

Deposits and withdrawals are still public. Where privacy ends

02 · Four movesThe full protocol

Less exposure.
Same Ethereum.

Everything you already do on-chain, minus the audience. Proofs are built in your browser in a few seconds; your keys never leave it.

03 · The crowd

Hide in
the crowd.

Every deposit becomes a leaf in one Merkle tree, and every leaf looks the same. When you spend, your proof says “one of these is mine” and never says which.
