Project Overview

Gelap is the first confidential RWA Dark Pool and private execution layer built on the Mantle ecosystem. It leverages SP1 zkVM to deliver verifiable correctness and privacy preservation without compromising decentralization.

This unique design allows users to:

- Utilize shielded vaults for depositing collateral.

- Execute private swaps with zero MEV.

- Trade Real-World Assets (RWAs) like T-bills and private credit without exposing their positions or strategies on-chain.

Gelap ensures market integrity by eliminating front-running and providing a compliance-ready infrastructure where institutional privacy meets decentralized settlement.

Powered by SP1 zkVM

Gelap utilizes SP1 zkVM as a core component for its Verifiable Settlement and Client-Side Proving mechanisms.

- Verifiable Settlement: SP1 is used to mathematically prove the validity of state transitions settled on-chain. This confirms that transactions were honest and followed all protocol rules without ever revealing the underlying sensitive data to the public ledger.

- Client-Side Proving: Users utilize SP1 technology to generate zero-knowledge proofs directly on their local device. This ensures that sensitive data never leaves the user's environment while still proving validity to the network.

- Off-Chain Logic: The SP1 prover validates critical logic off-chain, including Merkle inclusion proofs, ownership verification, and balance conservation, significantly reducing on-chain computation costs while maintaining security.

Privacy Architecture

Gelap enables a complete privacy lifecycle through three key stages:

1. Shielded Entry (Submit)

Users deposit assets into "Shielded Balances," decoupling their identity from their funds. This ensures that wallet history and transaction context remain completely unlinkable from the start.

2. Private Execution (Compute)

Transaction logic is executed off-chain using Client-Side ZK Proving. Trade intentions, amounts, and recipients are never exposed to the public mempool, effectively neutralizing MEV bots and preserving total privacy before the transaction is even sent.

3. Verifiable Settlement (Finalize)

By utilizing SP1 zkVM, Gelap proves the validity of state transitions on-chain. The protocol settles these proofs to confirm transaction honesty without revealing private inputs.

Contribution to the Mantle Ecosystem

Gelap is built on Mantle to address critical gaps and leverage ecosystem strengths:

- Solving the Institutional Privacy Gap: Institutions cannot trade RWAs on-chain if their NAV and order flows are visible. Gelap unlocks institutional capital for Mantle by protecting trade secrecy, making the ecosystem viable for high-value traditional finance players.

- Synergy with Native Yield: Gelap allows users to hold and trade yield-bearing assets (like mETH) within a shielded pool. Users maintain privacy without forfeiting the native yield that is unique to Mantle.

- The Zero-MEV Trading Experience: Gelap offers Mantle users a "Dark Pool" experience where sandwich attacks and MEV are impossible, creating the fairest execution environment on the network.

- First-Mover Advantage: As the first verifiable Confidential Dark Pool on Mantle, Gelap establishes itself as critical infrastructure, capturing early liquidity from privacy-conscious whales and institutions.

How It Works

Gelap operates through a set of integrated privacy modules:

- Main Interface: Users interact via a privacy-first dashboard to shield assets and execute trades.

- Shielded Pool Module: Users deposit tokens into a shared Merkle Tree, decoupling public identity from funds.

- Private Transaction Module: transfers and swaps occur internally without generating on-chain history (sender, receiver, and amount are hidden).

- Client-Side Proving Module: SP1 technology generates ZK proofs locally, ensuring data stays private.

- Verifier & Settlement: The on-chain contract verifies these proofs and updates the state (nullifying spent notes, creating new ones) without learning the inputs.

- Compliance Module: An opt-in layer allows institutions to prove compliance to auditors selectively.

Product Suite

- Private Swap: A privacy-first AMM that conceals trade amounts and identities, protecting users from MEV.

- Shielded Vault: Private yield-bearing pools for earning returns without revealing total holdings.

- Confidential RWA: A secure framework for tokenizing real-world assets with hidden ownership and values.

- Compliance Ready: An opt-in layer for providing cryptographic proofs of compliance to regulators.
