Events and Monitoring

Tilt vaults emit standard ERC-4626 events plus custom events for portfolio management. You can monitor these to track vault activity, build notifications, or feed data into analytics systems.

​
ERC-4626 Standard Events

event Deposit(address indexed sender, address indexed owner, uint256 assets, uint256 shares);
event Withdraw(address indexed sender, address indexed receiver, address indexed owner, uint256 assets, uint256 shares);
event Transfer(address indexed from, address indexed to, uint256 value);

​
Deposit

Emitted when an investor deposits tiltUSDC and receives shares.

​
Withdraw

Emitted when an investor redeems shares for tiltUSDC.

​
Transfer

Standard ERC-20 transfer event for vault share movements.

​
Monitoring with ethers.js

const vault = new ethers.Contract(VAULT_ADDRESS, vaultAbi, provider);

// Listen for new deposits
vault.on("Deposit", (sender, owner, assets, shares) => {
  console.log(`Deposit: ${ethers.formatUnits(assets, 6)} tiltUSDC from ${sender}`);
  console.log(`Shares minted: ${ethers.formatUnits(shares, 18)}`);
});

// Listen for withdrawals
vault.on("Withdraw", (sender, receiver, owner, assets, shares) => {
  console.log(`Withdrawal: ${ethers.formatUnits(assets, 6)} tiltUSDC to ${receiver}`);
  console.log(`Shares burned: ${ethers.formatUnits(shares, 18)}`);
});

​
Querying Historical Events

// Get all deposits in the last 1000 blocks
const filter = vault.filters.Deposit();
const events = await vault.queryFilter(filter, -1000);

events.forEach(event => {
  console.log({
    block: event.blockNumber,
    depositor: event.args.sender,
    amount: ethers.formatUnits(event.args.assets, 6),
    shares: ethers.formatUnits(event.args.shares, 18),
  });
});

​
Monitoring with viem

import { createPublicClient, http, parseAbiItem } from "viem";

const client = createPublicClient({
  chain: robinhoodL2,
  transport: http(),
});

const logs = await client.getLogs({
  address: VAULT_ADDRESS,
  event: parseAbiItem("event Deposit(address indexed sender, address indexed owner, uint256 assets, uint256 shares)"),
  fromBlock: "earliest",
});

​
Vault Discovery Events

Monitor the VaultRegistry for new vault deployments: 
const registry = new ethers.Contract(REGISTRY_ADDRESS, [
  "event VaultRegistered(address indexed vault, uint8 vaultType, address indexed curator)",
], provider);

registry.on("VaultRegistered", (vault, vaultType, curator) => {
  console.log(`New vault: ${vault} by ${curator} (type: ${vaultType})`);
});

​
Building a Notification System

Combine event monitoring with external services:
  1. Listen for Deposit/Withdraw events across all active vaults
  2. Process events to calculate metrics (AUM changes, share price movements)
  3. Alert via Telegram, Discord, or email when thresholds are crossed
  4. Store event data for historical analytics and track record computation
