Zero-knowledge privacy layer

Private money. Same Robinhood Chain.

Shield your assets once, then send, trade and withdraw on Robinhood Chain — without the chain linking any of it back to you.

EVMAny wallet works

Every transaction on a public chain tells a story. Who you pay. What you hold. When you move. FYER lets you decide who gets to read it.

How it works

Three steps. Zero traces.

Everything happens on Robinhood Chain. No bridges to a separate privacy chain, no new wallet to learn.

01

Shield

Deposit ETH or any supported token into the FYER pool. You receive a private note that only your key can spend.

02

Send & trade

Move value inside the shielded pool. A zk-proof shows the transaction is valid without revealing who, what or how much.

03

Withdraw

Unshield to any fresh address whenever you want. On-chain, there is no link between the deposit and the withdrawal.

Features

Privacy that feels like Robinhood.

◎

Zero-knowledge proofs

Every private action is backed by a succinct proof verified on-chain. Math, not trust.

⛨

Non-custodial

FYER can’t see, freeze or move your funds. Your keys, your notes, your money.

⚡

Built for Robinhood Chain

An Arbitrum Orbit L2 means low fees and fast confirmations for every shielded action.

FAQ

Questions, answered.

What is FYER?

FYER is a privacy layer for Robinhood Chain. It lets you shield assets into a zero-knowledge pool and then transact privately on the same chain.

Is FYER custodial?

No. Funds sit in an on-chain contract and can only be spent with proofs generated from your own keys. Nobody — including the FYER team — can move them.

Which wallets are supported?

Any EVM wallet that injects window.ethereum: MetaMask, Rabby, Coinbase Wallet, Robinhood Wallet and more.

What does it cost?

0.3% to shield, 0% for private transfers, 0.3% to withdraw — plus normal Robinhood Chain gas.

How do I get ETH on Robinhood Chain?

Bridge ETH from Ethereum or another supported network using the official Robinhood Chain bridge, then shield it with FYER.
