Phase 3: Protocol

Deployment Protocol

WIA-FIN-007 Phase 3 defines standardized deployment procedures ensuring consistent, secure, and verifiable contract deployment across all supported blockchains.

CREATE2 Deterministic Deployment

// WIA Standard Deployment using CREATE2
import { WIADeployer } from '@wia/deployer';
import { ethers } from 'ethers';

const deployer = new WIADeployer({
    privateKey: process.env.DEPLOYER_PRIVATE_KEY,
    rpcUrls: {
        ethereum: 'https://eth.llamarpc.com',
        polygon: 'https://polygon.llamarpc.com',
        arbitrum: 'https://arb1.arbitrum.io/rpc'
    }
});

// Compute deterministic address before deployment
const salt = ethers.utils.id('WIA-SecureToken-v1.0.0');
const predictedAddress = await deployer.computeAddress({
    bytecode: contractBytecode,
    salt: salt,
    deployer: deployerAddress
});

console.log('Contract will be deployed to:', predictedAddress);

// Deploy to multiple chains with same address
const deployment = await deployer.deployDeterministic({
    contract: 'WIASecureToken',
    bytecode: contractBytecode,
    constructorArgs: [],
    salt: salt,
    chains: ['ethereum', 'polygon', 'arbitrum'],
    initializeData: {
        name: 'WIA Token',
        symbol: 'WIA',
        decimals: 18,
        initialSupply: ethers.utils.parseEther('1000000')
    }
});

// Verify all deployments
console.log('Ethereum:', deployment.addresses.ethereum);
console.log('Polygon:', deployment.addresses.polygon);
console.log('Arbitrum:', deployment.addresses.arbitrum);
console.log('All addresses match:', deployment.allAddressesMatch); // true

Deployment Checklist

// Pre-deployment validation
const preDeployChecklist = await deployer.validatePreDeployment({
    contract: 'WIASecureToken',
    bytecode: contractBytecode,
    chains: ['ethereum', 'polygon']
});

console.log('Checklist:');
console.log('✓ Bytecode size < 24KB:', preDeployChecklist.bytecodeSizeValid);
console.log('✓ Constructor args valid:', preDeployChecklist.constructorArgsValid);
console.log('✓ Sufficient deployer balance:', preDeployChecklist.sufficientBalance);
console.log('✓ No existing deployment:', preDeployChecklist.addressAvailable);
console.log('✓ Security audit completed:', preDeployChecklist.auditCompleted);

if (!preDeployChecklist.allValid) {
    throw new Error('Pre-deployment validation failed');
}

// Deploy with comprehensive logging
const deployment = await deployer.deploy({
    contract: 'WIASecureToken',
    onStepComplete: (step) => {
        console.log(\`✓ \${step.name} completed on \${step.chain}\`);
        console.log(\`  Tx hash: \${step.txHash}\`);
        console.log(\`  Gas used: \${step.gasUsed}\`);
    },
    onError: (error, chain) => {
        console.error(\`✗ Deployment failed on \${chain}: \${error.message}\`);
    }
