Ecosystem Showcase & Launches

ntroducing Quantum DEX — the first native DEX on Arc Testnet with built-in CCTP cross-chain bridging.

QuantumExchange is a decentralized exchange purpose-built for Arc Network. The protocol provides seamless token trading, native cross-chain transfers, and liquidity provision infrastructure.

— Swap tokens with low slippage and real-time price quotes

 — Move USDC between Arc ↔ Base ↔ Ethereum seamlessly  

 — Add/remove liquidity with APR tracking

Real-time quotes with price impact warnings and MEV protection.

Bridge USDC to/from Base and Ethereum using Circle's CCTP V2 — no wrapped tokens needed.

Add liquidity, track your positions, and earn fees.

Q: What makes QuantumExchange different from other DEXs?

A: QuantumExchange is specifically architected for Arc Network's high-performance EVM environment. Unlike generic forks, we implemented custom routing algorithms (RouterQuantum_v2 and MultiHopRouter) to optimize for Arc's sub-second finality and low gas costs. Additionally, the native Circle CCTP V2 integration enables seamless USDC transfers between Arc, Base, and Ethereum without wrapped token intermediaries.

A: The core AMM logic is based on audited Uniswap V2 contracts (Factory, Pair, ERC20), but we developed custom router contracts that extend functionality. The MultiHopRouter finds optimal paths through intermediate pairs when direct liquidity is limited, and RouterQuantum_v2 provides gas-optimized swap execution.

A: We integrated Circle's Cross-Chain Transfer Protocol V2. When bridging USDC from Arc to Base, the protocol burns USDC on Arc and mints native USDC on Base through Circle's attestation service. This eliminates wrapped token risks and provides 1:1 backing guarantees.

A: On testnet: USDC (native Arc gas token), WUSDC (wrapped for pool compatibility), USDT, WETH, and QTM (Quantum governance token). Additional pairs will be added based on demand.

A: The Uniswap V2 base contracts are battle-tested and widely audited. Our custom contracts (routers, helpers, bridge integration) are currently in testnet phase. A full security audit will precede mainnet deployment.

Q: Can developers integrate with Quantum DEX?

A: Yes. All contracts are verified on Arcscan. We provide direct contract interfaces for swaps, liquidity provision, and bridge operations. Documentation for integrators is available upon request.

A: Frontend: Next.js 16, TypeScript, Wagmi/Viem, RainbowKit. Backend: Supabase for off-chain data (points, analytics). Smart Contracts: Solidity 0.8.20. Bridge: Circle CCTP V2 SDK.

A: Timeline depends on testnet performance metrics and completion of security audits. Updates will be posted in this thread.

Everything is running on testnet right now. Stack is Next.js + Wagmi/Viem, Solidity contracts, and the design uses glassmorphism with an interactive starfield background
