Shield
Deposit ETH or any supported token into the FYER pool. You receive a private note that only your key can spend.
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.
Send & trade
Move value inside the shielded pool. A zk-proof shows the transaction is valid without revealing who, what or how much.
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
