The problem Merdeka Swap solves

MerdekaSwap

MerdekaSwap is a decentralized, trustless Over-The-Counter (OTC) swap protocol built on the Lisk Sepolia Layer 2 network.

It enables users to trade any ERC-20 token directly with another party without slippage, using an off-chain order book (Supabase) for gas-less order creation and on-chain settlement for complete security.

🌟 Features

• Trustless OTC Swaps: Securely swap ERC-20 tokens with 0 slippage.
• Gas-less Listings: Creating an order is free (off-chain EIP-712 signature). Gas is only paid when filling an order.
• Private & Public Orders: Create orders for a specific wallet or open to the public.
• Xellar Wallet Integration: Seamless onboarding with Xellar's embedded wallet and social login.
• Fee Structure: A configurable protocol fee (default 0.1% or 10 BPS) is charged to the Maker upon success.
• Non-Custodial Listings: Assets remain in your wallet until the swap is executed. No depositing into a contract required.
• Shareable Order Links: Every order has a unique URL, perfect for sharing via DM or social media for direct deals.
• Verified Token Badges: Visual indicators for trusted tokens to ensure safety against impostor assets.
