Janus Protocol - Overview#
What is Janus?#
Janus is an institutional-grade, automated funding rate arbitrage vault built on the Arc L1 Network. Deposit USDC or EURC and earn 24–50% APY through fully automated, market-neutral trading strategies with no active management required.
The Problem#
- Funding rate arbitrage generates 20–50% annual returns but requires sophisticated infrastructure to execute
- Retail users have no access to this institutional strategy
- Existing DeFi yield products expose users to directional price risk
The Solution#
- One-click deposits: Connect wallet, deposit USDC or EURC, and earn automatically
- Market-neutral: Zero directional risk (BTC price movement doesn't affect your yield)
- Fully automated: Keeper bot monitors, executes, and rebalances 24/7
- Institutional safety: 5-of-9 multisig governance, insurance fund, on-chain audit trail
How It Works#
Funding Rate Arbitrage#
Perpetual futures have "funding rates", which are periodic payments between long and short traders that keep perpetual prices anchored to spot.
Example:
- Protocol A: +0.05% funding (longs pay shorts)
- Protocol B: +0.02% funding
- Spread: 0.03%
Janus does this:
- Opens SHORT on Protocol A (collects 0.05%)
- Opens LONG on Protocol B (pays 0.02%)
- Net: +0.03% every 8 hours = ~32% APY
- Zero directional risk: BTC price direction is irrelevant

Risk Disclosure#
Smart Contract Risk: Contracts are audited but DeFi is experimental. Only deposit what you can afford to lose. Insurance fund covers known exploits but does not guarantee 100% coverage.
Market Risk: Funding rates can go to zero (strategy pauses) or negative (strategy reverses). Extreme volatility can cause liquidation; this is mitigated by safety parameters.
Operational Risk: Keeper bot redundancy and monitoring minimize downtime. All protocol parameter changes are subject to a 24-hour timelock during which users may exit.
