mevchan

MEV-resistant relayer for Solana

Protect your transactions from front-running and sandwich attacks. mevchan combines zero-knowledge proofs with encrypted bundle submission to shield your intent before execution—with zero relayer fees and no Jito tips.

✓ 0% relayer fee

Zero-Fee Relaying

Route through mevchan with 0% relayer fee and no Jito tip for the demo layer.

Private Bundles

Submit encrypted bundles via our relayer endpoints to shield pre-execution intent.

MEV-Resistant Flow

Lower information leakage from user → relayer → validator → program.

How It Works

1

Client ZK Proofs

Build proofs in the browser; reveal only what's required.

2

Encrypt Payload

Encapsulate proof + minimal data for the relayer.

3

mevchan Relayer

Submit as a private bundle with 0% fee, no jitotip.

4

On-chain Verify

Your Solana program verifies and writes minimal state.

What is mevchan?

mevchan is a conceptual MEV-protection layer built on top of Jito's relaying model. It combines client-side ZK proofs, encrypted bundle submission, and on-chain verification to reduce pre-execution signal leakage—without fees or jitotip in this demo layer.

Security Model (demo)

This site demonstrates flows with mock endpoints. Use audited circuits and programs for production.

Example Flow

  1. POST /hash → derive commitment
  2. POST /prove → produce proof
  3. POST /verify → check proof
  4. POST /bundle/submit → encrypted payload routed without jitotip
  5. On-chain program verifies → updates state
