Avalanche Integration

Learn how to integrate Zelf with the Avalanche blockchain network.

Overview​

Zelf provides seamless integration with Avalanche, enabling secure identity verification and authentication on the Avalanche ecosystem.

Getting Started​

Prerequisites​

  • Avalanche wallet (MetaMask, Core, etc.)
  • Zelf SDK installed
  • Avalanche network access

Installation​

npm install @zelf/avalanche-sdk

Basic Integration​

JavaScript/TypeScript​

import { ZelfAvalanche } from '@zelf/avalanche-sdk';

const zelfAvalanche = new ZelfAvalanche({
  network: 'mainnet', // or 'testnet'
  rpcUrl: 'https://api.avax.network/ext/bc/C/rpc'
});

// Create ZelfProof for Avalanche
const createAvalancheProof = async () => {
  try {
    const result = await zelfAvalanche.createProof({
      walletAddress: '0x...',
      network: 'avalanche',
      purpose: 'identity-verification'
    });
    
    console.log('Avalanche ZelfProof created:', result);
    return result;
  } catch (error) {
    console.error('Error creating Avalanche proof:', error);
  }
};

        zelfProof = ZelfProof(_zelfProof);
    }
    
    function verifyIdentity(bytes32 proofId) public view returns (bool) {
        return zelfProof.isValid(proofId);
    }
    
    function registerIdentity(bytes32 proofId) public {
        require(zelfProof.isValid(proofId), "Invalid ZelfProof");
        // Register identity logic
    }
}

Best Practices​

Performance​

  • Use batch operations when possible
  • Implement proper gas estimation
  • Consider gas price fluctuations
  • Use appropriate gas limits

Security​

  • Validate all inputs
  • Implement proper access controls
  • Use secure random number generation
  • Regular security audits
