v3.0.0 Production Ready

Smart Contract Architecture

A deep dive into the Solidity Smart Contracts on Polygon that power the Emoji Weather Economy.

Core Components

ClimateIndexToken (CLM)

ERC20 collateral token with deflationary emissions and bootstrap mechanics.

ClimateEventToken (HOT/COLD)

Event-minted tokens tracking weather composites and volatility.

AllocationEngine

Strict 50/50 fee splitting and vesting schedule enforcement.

Security Features

Access Control

Role-based permissions (DEFAULT_ADMIN, MINTER, ORACLE) via OpenZeppelin.

Pausable

Emergency pause functionality for all critical contract operations.

Reentrancy Guard

Protection against reentrancy attacks on all external calls.

Implementation Details

solidity
// WeatherMath.sol
function calculateHeatComposite(
    uint256 heatIndex,
    uint256 hurricaneFactor,
    uint256 droughtIndex,
    uint256 wildfireRisk
) internal pure returns (uint256) {
    // Weighted composite calculation (0-10000)
    return (heatIndex * 4000 / COMPOSITE_PRECISION) +
           (hurricaneFactor * 3000 / COMPOSITE_PRECISION) +
           (droughtIndex * 2000 / COMPOSITE_PRECISION) +
           (wildfireRisk * 1000 / COMPOSITE_PRECISION);
