Private Routing Docs

Overview

This app provides a non-custodial way to reduce the on-chain linkage between a sender and a recipient. At a high level, funds move from the source network (e.g., Solana) into a privacy layer, are re-routed, then redeemed to a fresh destination address. The goal is to make typical graph analysis much harder by inserting a privacy- preserving hop in the middle. (Concept inspired by the public docs at mert.cash.)

How it works

• Non-custodial: You keep control of your wallet. The app orchestrates transactions; it does not hold your keys.
• Privacy hop: A dedicated privacy layer acts as an intermediate hop to weaken direct address linkability on the public chain.
• Fresh outputs: Withdrawals are redeemed to new addresses to avoid simple clustering.
• Proof-based checks: The system validates that inputs and outputs balance without revealing counterparties.

End-to-end flow

1. Connect: Link your wallet (e.g., Solana). No email or account required.
2. Prepare route: Choose an amount and destination address. The app estimates fees and timing.
3. Prove & relay: A proof is assembled and a relay executes the privacy hop. You sign the on-chain transactions.
4. Redeem privately: Funds are redeemed to your fresh destination address. Keep the receipt/notes for later auditing.

Fees & limits

• Network fees: Source and destination chain fees apply.
• Relay fee: A small relay/service fee is charged to cover routing infrastructure.
• Limits: Minimums/maximums may apply per route to maintain anonymity sets and operational safety.

Exact values can change over time. Always review the quote shown in the app before confirming.

Security notes

• Self-custody: Your private keys never leave your wallet.
• Fresh receive: Use new destination addresses and avoid re-using redemption outputs on public accounts.
• Timing hygiene: Delay public announcements or transfers that could trivially correlate inputs/outputs.
• Auditing: Keep local records (receipts/notes) for compliance or personal accounting.

Risks & caveats

• Linkability not zero: Privacy can be degraded by poor operational hygiene or small anonymity sets.
• Regulatory context: Laws vary by jurisdiction; you are responsible for lawful use.
• Volatility & settlement: Routes span multiple systems; fees/times can change with network conditions.
