ZIP-111: Impact Perpetuals Market

Abstract

This ZIP specifies a perpetual futures exchange for conservation outcome indices. Traders can take long or short positions on standardized indices that track measurable conservation metrics: species population trends, deforestation rates, ocean health scores, and carbon sequestration rates. Perpetuals use a funding rate mechanism to keep the mark price aligned with the index value. A fraction of all trading fees is directed to the conservation programs whose outcomes the indices track, creating a direct financial link between market activity and conservation impact.

Motivation

Conservation outcomes are not currently tradable, meaning:

No hedging: Conservation organizations cannot hedge against the risk of project failure. A perpetual on population indices would allow them to short their own index as a hedge.
No price signal: Markets aggregate information. A liquid conservation index market would surface the collective assessment of conservation project quality and trajectory.
No incentive alignment: Traders who profit from conservation improvement (long positions) have a natural interest in supporting the underlying programs.
Revenue generation: Trading fees on conservation perpetuals provide a novel, sustainable funding stream that scales with market activity.

Specification

1. Conservation Indices

Index	Components	Data Source	Update
ZOO-POP	Aggregate population index of 50 tracked species	ZIP-401 AI pipeline	Daily
ZOO-FOREST	Global forest cover index (baseline 2020 = 1000)	Global Forest Watch	Weekly
ZOO-OCEAN	Composite ocean health (temperature, pH, biodiversity)	NOAA + Zoo sensors	Weekly
ZOO-CARBON	Net carbon sequestration rate (tCO2e/day)	ZIP-108 on-chain data	Daily

Each index is normalized to a base value of 1000 at launch.

    struct Position {
        int256 size;             // Positive = long, negative = short
        uint256 margin;          // Collateral in ZUSD
        uint256 entryPrice;      // Average entry index value
        uint256 lastFundingTime;
    }

    struct Market {
        bytes32 indexId;
        uint256 markPrice;
        uint256 indexPrice;
        int256 fundingRate;        // Hourly funding rate (scaled 1e18)
        uint256 openInterest;
        uint256 maxOpenInterest;
        uint16 conservationFeeBps; // Fraction of trading fees to conservation
        address conservationDAO;
    }

    mapping(bytes32 => Market) public markets;
    mapping(bytes32 => mapping(address => Position)) public positions;

    uint256 public totalConservationFees;

    event PositionOpened(bytes32 indexed indexId, address indexed trader, int256 size, uint256 margin);
    event PositionClosed(bytes32 indexed indexId, address indexed trader, int256 pnl);
    event FundingPaid(bytes32 indexed indexId, int256 fundingRate, uint256 timestamp);

    function openPosition(
        bytes32 indexId,
        int256 size,
        uint256 margin
    ) external {
        Market storage market = markets[indexId];
        require(market.openInterest + abs(size) <= market.maxOpenInterest, "OI_CAP");

        uint256 tradingFee = (abs(size) * market.markPrice * 5) / 1000000; // 5 bps
        uint256 conservationFee = (tradingFee * market.conservationFeeBps) / 10000;

            margin: margin,

    function abs(int256 x) internal pure returns (uint256) {
        return x >= 0 ? uint256(x) : uint256(-x);
    }
}

3. Funding Rate Mechanism

The funding rate aligns mark price with the index value:

fundingRate = (markPrice - indexPrice) / indexPrice * fundingInterval

If mark > index: longs pay shorts (market is overpriced).
If mark < index: shorts pay longs (market is underpriced).
Funding is settled every 8 hours.
Maximum funding rate: +/- 0.1% per 8-hour period.

4. Oracle Requirements

Index	Primary Oracle	Secondary Oracle	Dispute Window
ZOO-POP	Zoo AI (ZIP-401)	IUCN data feed	24 hours
ZOO-FOREST	Global Forest Watch	Copernicus	48 hours
ZOO-OCEAN	NOAA	Zoo marine sensors	24 hours
ZOO-CARBON	ZIP-108 on-chain	Verra registry	48 hours

5. Risk Parameters

Parameter	Value	Governance
Maximum leverage	10x	ZooGovernor
Maintenance margin	5%	ZooGovernor
Liquidation penalty	2.5%	ZooGovernor
Insurance fund target	5% of OI	ZooGovernor
Conservation fee share	20% of trading fees	ZooGovernor
Position size limit	10% of max OI per address	ZooGovernor

6. Insurance Fund

An insurance fund absorbs negative PnL from bankrupt positions (liquidated below zero margin). Funded by:

50% of liquidation penalties.
Overflow from trading fees above the conservation allocation.
Direct contributions from the Zoo DAO treasury (ZIP-110).

Rationale

Why perpetuals over dated futures? Perpetuals provide continuous exposure without roll costs, are simpler for retail participants, and maintain a single liquidity pool per index rather than fragmenting across expiry dates.

Why conservation outcome indices? Novel markets on novel underlyings attract speculative interest, which generates the trading volume and fees that fund conservation. Traditional crypto perpetuals on BTC/ETH do not serve this mission.

Why 20% conservation fee share? The fee is high enough to generate meaningful conservation funding but low enough to keep the exchange competitive. At 5 bps total fee and 20% conservation share, the effective conservation cost per trade is 1 bps -- negligible for most traders.

Security Considerations

Index Manipulation

Conservation indices are harder to manipulate than token prices because they track real-world metrics. However, an attacker who compromises the oracle could move the index and profit. The 24-48 hour dispute window allows community challenge before settlement.

Cascading Liquidations

A sharp index movement could trigger cascading liquidations. The insurance fund and auto-deleveraging (ADL) mechanism cap the protocol's exposure. ADL reduces profitable counter-positions proportionally if the insurance fund is depleted.

Moral Hazard

Short positions profit from conservation failure. This is an inherent property of any two-sided market. Mitigation: conservation fee routing ensures short traders still contribute to conservation funding with every trade.

Low Liquidity

Niche indices may have thin order books. The protocol should bootstrap liquidity with DAO-funded market makers (ZIP-110 treasury strategies) and consider minimum liquidity thresholds before enabling leverage above 5x.
