Auto Liquidation
Positions below 5% margin ratio are liquidated by keepers. Liquidators earn 0.5% of notional — fully on-chain.
// HOW IT WORKS
Trade perps in
four steps.
From wallet connect to your first leveraged position in minutes. Everything runs on-chain on Arc Network — transparent and trustless.
Connect your wallet
Connect MetaMask and switch to Arc Testnet. USDC is the native gas token — get test USDC from the Circle faucet to start trading.
// Add Arc Testnet to MetaMask chainId: 5042002 rpc: rpc.testnet.arc.network currency: USDC
Approve USDC & open a position
Approve the engine contract to spend your USDC. Then pick your market, set your leverage up to 50x, and go long or short.
// Open a $1000 BTC long at 10x asset: "BTC" isLong: true collateral: 1000 USDC leverage: 10x // → $10,000 notional position
Monitor your position
Track your unrealized PnL in real time from the Portfolio page. Oracle prices update every 60 seconds keeping everything accurate.
// Position state on-chain entryPrice: $104,921 currentPrice: $105,843 pnl: +$878.20 USDC marginRatio: 18.7%
Close & settle in USDC
Close your position anytime. Your collateral plus profit is paid out instantly from the vault in USDC — no wrapping, no bridging.
// closePosition(positionId) payout: collateral + pnl - fee settlement: instant USDC fee: 0.10% of notional
// INFRASTRUCTURE
Built on Arc.
Settled in USDC.
Arc Network is Circle's EVM-compatible L1 with USDC as the native gas token. Every trade, every fee, every settlement happens in USDC — no wrapping, no bridging.
// PROTOCOL STATS
Built for serious
on-chain traders.
// INTEGRATIONS
Powered by the
best in the stack.
Arc Perp DEX integrates best-in-class infrastructure across every layer — from settlement to price feeds to frontend tooling.
// SECURITY
Trustless by design.
Transparent by default.
Arc Perp DEX is built with a security-first architecture. No admin keys. No upgradeable proxies. Every dollar traceable on-chain.
Non-Custodial
Your funds never leave the smart contract. The vault holds USDC and only pays out on valid position closes. No admin keys, no multisig backdoors.
On-Chain Settlement
Every openPosition and closePosition call is a real on-chain transaction. PnL is calculated deterministically from oracle prices, verifiable by anyone.
Margin Protection
Positions are liquidated at 5% margin ratio before they can go insolvent. The vault reservedMargin system ensures LP funds are never at risk.
Oracle Safety
Prices revert if stale beyond 5 minutes. The keeper bot pushes updates every 60s from CoinGecko. No position can open or close with a stale price.
Open Source
All three contracts are verified and readable on ArcScan. No proxy patterns, no upgradeable contracts. What you see is what runs.
Arc TEE Privacy
Arc Network supports confidential transfers via Trusted Execution Environments. Future versions will support private position sizes while keeping settlement on-chain.
// DEVELOPERS
Simple contracts.
Powerful protocol.
Three clean Solidity contracts. No proxy patterns, no complexity.
// 1. Approve USDC usdc.approve(ENGINE_ADDRESS, collateral); // 2. Open 10x BTC long engine.openPosition( 'BTC', true, 100e6, 10 );
