Origin Overview

Origin is the institutional-grade global exchange on Arc that unifies trading into one venue, letting users deposit any stablecoin currency as collateral and access perpetuals on every major market with 24/7 trading. Origin features stablecoin-native settlement, verifiable matching, low-latency execution, and compliance-ready infrastructure for global capital markets.

What Origin Is

Origin is a hybrid perpetual futures exchange that combines the speed and liquidity of centralized trading with the custody guarantees of on-chain settlement. It consolidates crypto, equity, and commodity perpetuals into a single unified venue where users deposit collateral once and trade across all major markets 24/7.

Core Mission

1. The Global Exchange - Trade any asset against any stablecoin currency. Origin breaks the USD monopoly by accepting EURC, KRW1, JPYC, and other Circle-integrated stablecoins as collateral, enabling traders worldwide to use their local currency without forced conversion.

2. The Wall Street Oracle - Provide continuous 24/7 price discovery even when traditional markets are closed. Origin serves as the reference price source during off-hours, holidays, and market gaps.

3. Institutional DeFi - Deliver compliance-ready infrastructure with KYC/AML support, surveillance capabilities, and operational rigor that institutional desks require while maintaining the transparency and self-custody properties of DeFi.

Architecture at a Glance

Origin uses a hybrid on-chain/off-chain design that optimizes for both performance and trustlessness:

Key insight: Users always retain on-chain custody of their collateral. The off-chain operator can match orders and compute risk, but cannot move funds out of the system, increase debt beyond collateral, or override parameters. The worst-case operator failure is bounded—trading halts, but funds remain accessible.

Settlement Flow

1. Orders match off-chain in the Matching Engine (sub-10ms)
2. Fills accumulate in settlement batches
3. Batches commit to Arc every 250-500ms during peak activity
4. On-chain settlement provides deterministic finality in under 1 second

Key Innovations

Virtual Cross-Currency Markets

Origin exposes markets like GOOGL/KRW, BTC/EUR, and XAU/JPY without fragmenting liquidity. Instead of separate orderbooks for every currency pair, virtual markets compose canonical USD-denominated perpetuals with an FX overlay:

GOOGL/KRW = GOOGL/USD-PERP + USD/KRW FX layer

• All liquidity concentrates around USD books—market makers quote one book, users see their local currency
• Funding rates remain unified regardless of display currency
• FX risk is on the collateral, not the position

Multi-Collateral with Dynamic Haircuts

Origin accepts the full range of Circle StableFX stablecoins (USDC, EURC, KRW1, JPYC, MXNB, etc.) plus crypto (BTC, ETH) and RWAs (USYC) as collateral. Non-USD collateral is subject to dynamic haircuts that adjust in real-time based on:

• FX volatility
• Bid/ask spread
• RFQ depth at $1M+
• Currency concentration
• Issuer risk signals

Robust Mark Price

Liquidations trigger on a three-source median designed to be manipulation-resistant:

mark_price = median(impact_price, cex_median, ema_orderbook)

This is separate from the Pyth index price used for funding—an attacker would need to compromise at least two of three independent sources to trigger unfair liquidations.

Partial Liquidations

Unlike exchanges that fully close positions at liquidation, Origin uses partial liquidations that close only enough of the riskiest position(s) to restore the account to safety. This leaves residual equity with the user rather than seizing the entire position.

Self-Custody Emergency Exit

If the off-chain operator becomes unresponsive for 24+ hours, the system auto-transitions to EMERGENCY_EXIT state. Users can withdraw their free collateral directly on-chain without operator participation—no withdrawal queue, no frozen funds.

Who Origin Is For

Core Concepts

Account Health States

Accounts exist in one of three health states that determine available operations:

Margin Modes

• Cross Margin (default): All positions share the entire collateral pool. Unrealized PnL on profitable positions offsets margin requirements on others—maximum capital efficiency for portfolios.
• Isolated Margin: Allocate specific collateral to a single position. Losses cannot exceed the allocation—useful for high-conviction directional trades.

Funding Rate

The periodic payment between longs and shorts that anchors the perpetual's mark price to its underlying index. Origin uses the standard premium-plus-interest construction, settled every 1 hour, hard-capped at ±4% per interval.

Insurance Fund + ADL

The insurance fund absorbs liquidation shortfalls when a position closes below its bankruptcy price. If the fund is depleted, Auto-Deleveraging (ADL) closes positions of the most-profitable, most-leveraged counterparties on the opposite side as a last-resort mechanism.

Built on Arc

Origin runs on Arc, Circle's Layer-1 blockchain purpose-built for stablecoin finance:

• USDC-denominated gas — predictable transaction costs in USD terms
• Deterministic sub-second finality — no probabilistic confirmations
• EVM compatibility — standard tooling, standard contracts
• Native Circle integration — first-class support for Circle Mint, CCTP, Gateway, and StableFX
