The Easy Way to Add Customizable, Real-time Transaction Notifications to Your Dapp with Web3 Onboard

Blocknative Ethereum Web3

Reduce transaction anxiety and prepare for a multi-chain future

Blocknative is excited to introduce real-time transaction notifications and customizable alerts for Web3 Onboard to help improve the developer experience and reduce user churn on your decentralized application. 

Whenever real value is exchanged, users expect accurate and timely transaction notifications. In cases where a transaction behaves unexpectedly– stalled, stuck, dropped, or failed – it is imperative to provide real-time, actionable alerts so users can respond accordingly. Not doing so can lead to increased transaction anxiety and, ultimately, user churn.

But providing notifications can be a costly development task—both to build and maintain. Web3 Onboard is the fast and simple way to push notifications to your users for free. Our transaction notifications are already trusted by thousands of applications across six blockchain networks to ensure users can transact with confidence.



Example of transaction notifications in Web3 Onboard

What’s included in Web3 Onboard notifications?

Web3 Onboard enables push notifications through an easy-to-use, lightweight, open-source, front-end javascript library that leverages our robust mempool API and SDK to simplify the developer experience and make it quick and easy to integrate real-time notifications on your dapp.

By integrating Web3 Onboard as your connect wallet button of choice, your dapp can enable:

Real-time Transaction Alerts

Transaction Alerts

Powered by our Transaction Orchestration platform and real-time Mempool API, Web3 Onboard alerts enable your users to monitor their entire transaction lifecycle from the moment it enters the mempool until the moment it is finalized – or replaced. 

As a transaction moves through the mempool, Web3 Onboard will notify users of the state change— you can try it yourself on Like all other parts of Web3 Onboard, these push notifications can be fully customized to match the look and feel of your application.  


Customizable Hint Notifications

In addition to transaction notifications, developers can also program customizable alerts or “hints” for any specific triggers to help guide the user’s next actions and reduce user friction. 

For example, if a transaction requires an approve before a swap, hint notifications can be used to guide users through the experience, informing them that they are currently conducting one of two transactions. NFT drops could use notifications to update users on how many mints remain to set user expectations. Or, if ETH gas prices are exceptionally high, dapps can warn their users to prevent potentially stuck transactions. 

Because these crypto push notifications are composable, the possibilities are endless! 


Multi-Chain Support: Notifications Across Six Blockchain Networks

By integrating Web3 Onboard, developers can allow users to monitor transactions between networks and significantly simplify transacting on Layer-2 protocols, which are increasingly leveraged for their speed and scalability. Web3 Onboard currently supports real-time alerts across Ethereum, Polygon, and Gnosis.


Desktop and Mobile Functionality

Web3 Onboard’s push notifications work on every device, so your dapp can keep users up-to-date, whether they are using a desktop or a phone.


Plus, so much more!

How to enable transaction notifications
on Web3 Onboard

Notifications are an optional feature for Web3 Onboard integrators. To enable notifications, developers simply need to add a dappId (API Key) and have Account Center turned on in the latest version of web3 onboard. 

Enabling transaction notifications is free on most supported chains and requires a Blocknative account to connect to our API. Users can always upgrade to a paid plan if they require a higher volume of API events or additional coverage.


How to get a dappID

After creating your Blocknative account, visit the Account page and add a new API key. Copy this API key to be used as your dappId to enable notifications on Web3 Onboard. 


Add new API key button on the Account page


Blocknative will create a default API key for you, but it is recommended you create your own as API keys segment analytics data. Consider using different API keys for development, staging, and production releases.

More information on how to enable notifications on Web3 Onboard can be found in our API docs.
