Smart Contracts

Contract Integration

import { ethers } from 'ethers';
import VaultManagerABI from './abis/VaultManager.json';

// Connect to contract
const vaultManager = new ethers.Contract(
  '0x...', // VaultManager address
  VaultManagerABI,
  signer
);

// Create vault
const tx = await vaultManager.createVault(
  "My Inheritance Vault",
  0, // ReleaseType.SCHEDULED
  ["0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb"],
  true // encrypted
);

const receipt = await tx.wait();
const event = receipt.events.find(e => e.event === 'VaultCreated');
const vaultId = event.args.vaultId;

console.log('Vault created:', vaultId.toString());

// Query vault
const vault = await vaultManager.getVault(vaultId);
console.log('Owner:', vault.owner);
console.log('Status:', vault.status);

// Listen for events
vaultManager.on('VaultReleased', (vaultId, timestamp) => {
  console.log(`Vault ${vaultId} released at ${new Date(timestamp * 1000)}`);
});

Usage Example

import TimeManagerABI from './abis/TimeManager.json';

const timeManager = new ethers.Contract(
  '0x...', // TimeManager address
  TimeManagerABI,
  signer
);

// Configure deadman switch
await timeManager.configureDeadmanSwitch(
  vaultId,
  90 * 24 * 60 * 60,  // 90 days check-in period
  7 * 24 * 60 * 60    // 7 days grace period
);

// Perform check-in
await timeManager.checkIn(vaultId);

// Check if triggered
const isTriggered = await timeManager.isDeadmanTriggered(vaultId);
if (isTriggered) {
  console.log('Deadman switch triggered - vault unlockable');
}

// Get time remaining
const timeRemaining = await timeManager.getTimeUntilUnlock(vaultId);
console.log('Days until unlock:', timeRemaining / (24 * 60 * 60));

Factory Pattern

interface IVaultFactory {
    // Deployment
    function deployVault(
        bytes memory initData
    ) external returns (address vaultAddress);

    // Queries
    function getVaultImplementation()
        external view returns (address);

    function isVault(address addr)
        external view returns (bool);

    // Events
    event VaultDeployed(
        address indexed vaultAddress,
        address indexed owner,
        uint256 timestamp
    );
}

// Gas-efficient deployment using minimal proxy
await vaultFactory.deployVault(initData);
// ~50K gas vs ~500K for regular deployment
