stay unlinked

I build ephemeral, the private receive layer for Ethereum: stealth payments on L1 (ERC-5564), where every payment lands on a fresh address. Measured first, shipped in public, every claim linked to something you can check.

01proof · the leak study

4 in 10 withdrawn stealth payments get traced. I measured it.

An open-source scanner re-ran the 2023 Kovács & Seres Umbra study on the full history of Ethereum mainnet: every Umbra and ERC-5564 payment up to block 26,176,190. It publishes aggregate counts only, never addresses.

Sirius's Lab

I rate new projects on one question: can a stranger link your main wallet to what a project paid you?

This week's most active projects that move value to users: rewards, claims, payouts, creator fees. Public data only, a link for every claim. Projects get a right of reply, re-rated within 24h, every change logged.

stage 0Public mapA stranger can link what you received.
stage 1Private optionYou can receive unlinked, opt-in.
stage 2Private by defaultUnlinked by default, nothing to fingerprint.
