About Mixoor on Robinhood Chain
Mixoor lets you transfer native ETH through a non-custodial privacy pool on Robinhood Chain, an Ethereum-compatible Layer 2 with chain ID 4663 and ETH as its gas token. Groth16 proofs are generated in your browser and verified onchain, reducing the direct link between the funding wallet and recipient without promising complete anonymity.
How it works
Deposit native ETH
Deposit native ETH into the Mixoor pool. The transaction records a cryptographic commitment used for a later withdrawal.
Generate a proof and withdraw
Generate a Groth16 proof in your browser, then send the withdrawal through the relayer to the recipient address.

Frequently Asked Questions
What is Robinhood Chain?
Robinhood Chain is a permissionless, Ethereum-compatible Layer 2 with chain ID 4663. ETH is its native gas token.
Which assets does Mixoor support on Robinhood Chain?
This Mixoor deployment currently supports native ETH through one ETH pool. Supporting another asset would require a separate pool configuration; this does not describe every asset available elsewhere on Robinhood Chain.
What is the fee for Mixoor on Robinhood Chain?
The configured relayer fee is 0.25% of the withdrawal amount, with no separate Mixoor deposit fee. Standard Robinhood Chain gas costs may still apply to wallet transactions.
What is the minimum deposit on Robinhood Chain?
The Mixoor ETH pool enforces a minimum deposit of 0.01 ETH.
What privacy does Mixoor provide on Robinhood Chain?
Mixoor uses a pool and a client-generated Groth16 proof to reduce the direct onchain link between the funding wallet and recipient. Blockchain activity and surrounding metadata remain public, so Mixoor does not guarantee complete anonymity or conceal all public activity.
Is Mixoor non-custodial?
Yes. Mixoor never holds user funds. Deposits go to a smart contract pool, withdrawals are authorized by zero-knowledge proofs that only the depositor can generate.
Is Mixoor open source?
Yes. The on-chain programs, ZK circuits and SDKs are open source under the Apache 2.0 license. The repositories are public on GitHub under SmithiiDev.
