About Mixoor on Solana
Mixoor on Solana is a non-custodial private transfer tool that lets you transfer SOL and SPL tokens (including USDC) privately. It uses Groth16 zero-knowledge proofs verified by an on-chain Anchor program to reduce the direct link between your deposit and recipient wallets, with no relayer custody and less exposed wallet linkage on chain explorers.
How it works
Deposit privately
Send SOL or USDC into the Mixoor pool. A cryptographic commitment hides which deposit is yours.
Withdraw to a fresh wallet
Generate a Groth16 ZK proof client-side and withdraw to any address, with no on-chain link to the original deposit.

Frequently Asked Questions
What is the fee for Mixoor on Solana?
Mixoor charges a 0.15% protocol fee on the sending amount. There is no deposit fee. The fee is taken from the withdrawn amount; the recipient receives the gross amount minus the fee.
How does Mixoor reduce the link between deposit and recipient?
When you deposit, Mixoor stores a cryptographic commitment instead of your address. To withdraw, you generate a Groth16 zero-knowledge proof that you know the secret behind one of the commitments without revealing which one. The proof verifies on-chain and lets a fresh wallet receive the funds.
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.
