The curve fills in public. Your position doesn't.
A bonding-curve launchpad on Robinhood Chain. Buy privately while the curve fills, with protection against bundlers and snipers.

Early buyers shouldn't be targets.
On a public curve, every buy is a signal. Bots read it, bundlers beat it and traders copy it. Umbra removes the signal without hiding the curve.
Private buys
Shield ETH into fixed-size notes, then buy through a relayer using a zero-knowledge proof. Your tokens land at a fresh address that nothing links to your wallet.
Anti-bundling
Contract-enforced wallet limits, a burst limit and a sealed opening. On strict launches, Sentinel also screens public buyers for signs of bundling before they can buy.
AI risk read
Every launch is scored from live on-chain data: holder concentration, suspicious buyers, creator history and buyer spread. AI explains the result in plain language.
Locked liquidity
When the curve fills, all its ETH and 200M tokens go into a Uniswap pool, and the LP tokens are burned. Nobody can ever pull that liquidity.
How the privacy layer works.
See the full flow- 1
Shield ETH
Move ETH into your private balance as fixed-size notes. People can see you funded the pool, but not what you buy with it.
- 2
Buy with a proof
Your device proves you own a note without saying which one. A relayer submits it, so the buy never touches your wallet.

The batch settles
Orders settle together every 60 seconds at one blended price. Tokens then go to a fresh private address.
