Introduction
Opaque is a shrouded pool on Robinhood Chain. Shroud $OPA into private notes to hold and send them without putting your balance or wallet history on display, and to earn from protocol fees.

On most blockchains, anyone can look up an address and see what it holds and every payment it has made. $OPA is an ordinary ERC-20 on Robinhood Chain, launched on the Pons launchpad. Opaque is its private side: when you shroud $OPA, it moves into the Opaque pool and becomes a private note that only you can spend. From there you can send it, or take it back out to any address.
What makes it different
- Private when you choose: Shroud $OPA into notes. Balances and who pays whom inside the pool stay hidden, proven with zero-knowledge proofs. Shrouding and withdrawing are public transactions.
- Trades like any token: $OPA is a plain ERC-20. Wallets, exchanges and aggregators work unchanged.
- Paid to stay private: Fees flow to the $OPA vault behind private notes. Only notes earn. Public $OPA does not. Soon: an automated keeper routes trade fees into the vault.
- No operator: The pool cannot be upgraded and has no admin. The one pause stops only new deposits, never spends or exits.
How it fits together
- Hold. You buy $OPA on its Pons curve, on Uniswap v4 after it graduates, or through an aggregator.
- Shroud. You deposit $OPA into the pool. The deposit is public. What you receive is a private note.
- Earn. Fees are donated into the vault that backs $OPA notes, so the value of each note's share rises over time. Public holders do not earn.
- Move. You send notes privately, or exit to any address with a zero-knowledge proof. The exit is public.
