building ephemeral in the open,.
need 10 people who actually care about onchain privacy to break the app before launch
bugs, ideas, roasts. all welcome
early access group in the reply ⛓️💥

gm.
on the desk today: withdraw rules that start closed.
all five leak habits, h1 to h5, blocked by default until you open one on purpose.

I’ve known Sirius for years and worked alongside him on deals, so this isn’t a vouch based on words alone.
I’ve also watched him build Ephemeral quietly for weeks before saying a word about it. Most people are good at talking. Fewer actually put in the work.
He does what he says. That’s really all you need to know about how someone operates.
Solid guy, no unnecessary ego, treats people right. Always had respect for people who let their work speak for itself 💯

ephemeral can be the top privacy project on ethereum.
i'm not hedging that.
not vibes. numbers. read it once.
every payment you receive on ethereum lands on an address anyone can read.
salary. invoices. tips. agent payments.
one address. one public history.
erc-5564 fixes the receive side on l1.
a fresh one time address for every payment. only you can find it.
the standard is final.
almost nobody uses it.
erc-6538, its registry, has 9 registrations on mainnet.
9. ever.
that's not a dead idea. that's an empty field.
we rescanned 25,057 withdrawn stealth addresses.
38.92% link back to their owner.
not broken crypto. habits.
so we built the client around the withdrawal.
it catches the habits that leak before you confirm.
nobody else on l1 ships that check.
first mover on stealth receiving. full stop.
revenue in plain words.
the hook on our official pool earns real eth on every trade.
not emissions. not points.
treasury and team, onchain, every payout readable.
receipts over hype.
verified contracts. no owner. public method.
my founder wallet sits on the verify page.
what's coming.
buy privately from the app.
private ens names.
pay in any token.
a public erc-5564 dashboard on dune.
why now.
payments are going onchain.
glamsterdam makes the chain easier to read.
a receiver nobody can map matters more with every upgrade.
the goal is simple.
top privacy project on dune and defillama.
by real numbers. not followers.
i don't need you to believe me. i need you to check.
the long version is in the lab: t.me/siriusgem
nfa. i don't do price talk.
unpopular: on $ETH most privacy talk is about hiding the sender.
the receiver is the one who gets mapped. salary, payouts, grants, all landing on one address anyone can watch.
thats why i build the receive side first.
ALT the receiver is the one who gets mapped.
how a stealth payment lands on $ETH, in 4 steps:
1. you publish one meta-address
2. the payer derives a fresh address for this payment
3. it lands there with a small public note (erc-5564)
4. your viewing key finds that note. nobody else can
everyone else sees a new address.
ALT how a stealth payment lands: one meta-address, a fresh address per payment, a public note only your viewing key can read as yours
shipped: my withdraw check now sees token moves with zero eth attached.
erc-1155 transfers too, single and batch.
why: a withdrawal can move tokens without moving any eth.
found through the bug bounty, fixed in public:
github.com/siriusthemaster/e…
ALT shipped: the withdraw check reads more of the chain. zero eth token moves, erc-1155 transfers, fixed in public

unpopular take the destination check belongs in the wallet before signing
Data drop: 9,711 addresses, one habit.
On Ethereum mainnet, 9,711 of 25,057 withdrawn stealth addresses link back to their owner through H1: the money went to the wallet that registered the stealth keys.
The app beta blocks that destination before you sign.
ALT 9,711 withdrawn stealth addresses went back to the wallet that registered their keys, of 25,057 withdrawn on Ethereum mainnet.

who sees what in a private payment on $ETH:
payer: your meta-address and the fresh address it made
chain: a payment to a new address, a public note
you: which notes are yours, via your viewing key
everyone else: who paid, how much, to an unlinked address
weak spot: the exit.
ALT One private payment, four views: the payer, the chain, you, and everyone else.
every build i ship gets tested in one room first.
early access gets it before anyone: keys, receive, the withdraw checks. members try to break it, i fix what they find.
if you'd rather check the code than read threads about it, come break it.
ALT The ephemeral app beta: every payment lands on a new address. Keys come from one signature and never leave the tab.
unpopular: you don't have to leave ethereum to stop being mapped.
$XMR has used one-time addresses on its own chain from the start. erc-5564 brings that idea to the receive side on l1, as an open standard.
that's what i'm building, plus a check so the exit doesn't undo it.
ALT What people think: privacy means moving to another chain. What I'm building: a fresh address for every payment, on L1.
how my lab rates a project, in 3 steps:
1. follow what it pays users: rewards, claims, payouts
2. ask: can a stranger link the receiver's main wallet to it from public data?
3. score 7 rows with evidence. the weakest row sets the stage, 0 to 2
unverified rows never help.
ALT Lab privacy stages in 3 steps: follow the payout, ask if public data links it to the receiver's main wallet, score 7 rows with evidence.
got asked: can you see my payments or move my funds?
no. your keys come from one signature of your wallet, made in your browser. the viewing key stays on your device.
signing never moves funds and nothing is stored on my side. only your keys can spend what lands there.
ALT Dev answer card: your keys are made in your browser. they never come to me.
hot take: private payments are easy. private exits are the product.
on $ETH a fresh address per payment works. people get found when the money moves to a wallet everyone knows.
so my check runs before you withdraw, not after.
key wallet or exchange, where do you withdraw to?
ALT Hot take card: private payments are easy. private exits are the product.
