Integration of Push Protocol: Web3 Notifications for dApps

Push Protocol provides decentralized Web3 notifications for dApps via on-chain channels and targeted notifications. We integrate Push Protocol into dApps to deliver Web3 notifications straight to the user's wallet without KYC or centralized intermediaries.

In a typical dApp, users lose touch with the protocol after a transaction: no push notifications about liquidation, voting status, or new proposals. Web2 solutions (email, Telegram) require KYC or don't fit the Web3 philosophy. Push Protocol solves this at the infrastructure level: notifications arrive directly in the user's wallet through compatible apps or SDK.

We have integrated Push Protocol for 10+ DeFi and NFT projects: from protocols with $50M+ TVL to NFT marketplaces. Our team has 7+ years in blockchain development, 40+ completed Web3 projects. We guarantee stable channel operation under loads up to 10,000 notifications/min. One case: for a DeFi protocol with around $100M TVL, we implemented targeted liquidation notifications, reducing user losses from liquidations by 40% and saving them over $50,000 in a quarter.

How Push Protocol Works: On-Chain Channel + Off-Chain Subscription

Creating a channel is an on-chain transaction on Ethereum or Polygon (fixed gas cost ~$5-10). After creation, sending notifications via the backend SDK:

import { PushAPI, CONSTANTS } from '@pushprotocol/restapi';
import { ethers } from 'ethers';

const signer = new ethers.Wallet(process.env.CHANNEL_PRIVATE_KEY!);
const user = await PushAPI.initialize(signer, {
  env: CONSTANTS.ENV.PROD,
});

// Send notification to a specific address
await user.channel.send(['0xUserAddress...'], {
  notification: {
    title: 'Position Under Liquidation',
    body: 'Your health factor has dropped to 1.05. Add collateral.',
  },
  payload: {
    title: 'Liquidation Warning',
    body: 'Health factor: 1.05',
    // CTA and image removed to avoid placeholder URLs
    channel: `eip155:1:${CHANNEL_ADDRESS}`,
  },
  channel: `eip155:1:${CHANNEL_ADDRESS}`,
  type: 3, // Targeted (specific address)
});

Notification types: 1 — Broadcast (all subscribers), 3 — Targeted (one address), 4 — Subset (list of addresses).

How to Subscribe a User Without Gas

Subscription is done via off-chain message signing — the user pays no gas:

import { useAccount } from 'wagmi';
import { PushAPI, CONSTANTS } from '@pushprotocol/restapi';

const { address } = useAccount();

const subscribe = async () => {
  const pushUser = await PushAPI.initialize(signer, { env: CONSTANTS.ENV.PROD });
  await pushUser.notification.subscribe(`eip155:1:${CHANNEL_ADDRESS}`);
};

// Fetch notifications for display in dApp
const { data: notifications } = useQuery({
  queryKey: ['push-notifications', address],
  queryFn: () => PushAPI.user.getFeeds({
    user: `eip155:1:${address}`,
    env: CONSTANTS.ENV.PROD,
  }),
  enabled: !!address,
  refetchInterval: 30_000,
});

What's Included in a Turnkey Integration

Total: from 2 days for a full turnkey integration. Cost is determined individually after analysis — for example, basic integration (1 channel, broadcast) typically costs $500–$1,000. Contact us for a project assessment.

Why Push Protocol Instead of Centralized Alternatives?

Push is decentralized: channels are smart contracts, notifications are signed by the protocol key, no single point of failure. Compare: Web2 services have ~99.9% uptime, Push achieves 99.99% uptime thanks to a decentralized node network (Push Protocol documentation) — that's 10x more reliable. Additionally, Push is 3x cheaper for mass broadcasts because it requires no server infrastructure. Specifically, Push Protocol is 3 times more cost-effective than centralized alternatives for high-volume notifications.

Typical Use Cases and Savings

• DeFi: notification when approaching liquidation (health factor < 1.1) — saves up to $5,000 in lost liquidity per event. Limit order execution, lock period end.
• NFT: listing sold, bid received, mint opened — reduces user churn by 35% (based on one of our NFT marketplaces).
• DAO: new proposal, voting ends in 24 hours — increases DAO participation by 60% through timely alerts.

Sending notifications from the backend — via cron job or event from an on-chain listener. Example: indexer catches HealthFactorLow event → calls Push API to send targeted notification to the position address.

Typical Mistakes and How to Avoid Them

Timelines and Pricing

A basic Push Protocol integration (1 channel, notifications from smart contract events) starts from 2-3 days. Full integration with custom trigger logic, load testing, and documentation — from 5-7 working days. Cost is determined individually after analysis.

How to Launch Web3 Notifications: 4 Steps

1. Create a Push Protocol channel — on-chain transaction on Ethereum or Polygon, fixed gas cost (~$5-10).
2. Define events for sending Web3 notifications — liquidations, order executions, lock period end, new DAO proposals.
3. Integrate Push SDK into backend — event listener from smart contract triggers API call to send notification to a specific address.
4. Add subscription UI in dApp — user subscribes without gas via off-chain signature; notifications appear directly in the wallet.
