# Contract Addresses

> ZKScore smart contract addresses across all supported networks

## Overview

ZKScore contracts are deployed across multiple networks. Use these addresses to interact with the contracts directly.

## Usage Examples

### JavaScript/TypeScript

```javascript theme={null}
// Contract addresses
const CONTRACTS = {
  ethereum: {
    identitySBT: '0x1234567890123456789012345678901234567890',
    scoreCalculator: '0x2345678901234567890123456789012345678901',
    achievementRegistry: '0x3456789012345678901234567890123456789012',
    trustRegistry: '0x4567890123456789012345678901234567890123',
    protocolRegistry: '0x5678901234567890123456789012345678901234'
  }
};

// Using with ethers.js
const identityContract = new ethers.Contract(
  CONTRACTS.ethereum.identitySBT,
  identitySBTABI,
  provider
);
```

### Solidity

```solidity theme={null}
// Import contract interfaces
import "@zkscore/contracts/interfaces/IIdentitySBT.sol";
import "@zkscore/contracts/interfaces/IScoreCalculator.sol";

// Contract addresses
address constant IDENTITY_SBT = 0x1234567890123456789012345678901234567890;
address constant SCORE_CALCULATOR = 0x2345678901234567890123456789012345678901;

// Use in your contract
IIdentitySBT identity = IIdentitySBT(IDENTITY_SBT);
IScoreCalculator scoreCalc = IScoreCalculator(SCORE_CALCULATOR);
```
