API for Bitcoin and Ethereum

Now You Can Monitor the Bitcoin Mempool with Blocknative’s Notify API

Every minute, blockchains move over $2 million in value. But understanding and acting on this in-flight value is challenging for even the most sophisticated and well-resourced of teams. Before any transaction can be confirmed on-chain, it must move through the mempool. As we have previously discussed, this is an often overlooked portion of the blockchain ecosystem. 

At Blocknative, we run Notify — a global node network that captures and organizes mempool transactions in real-time. Historically, we have focused on the Ethereum blockchain. Today, we are excited to announce the addition of Bitcoin support to our distributed node infrastructure.

Now developers can access real-time state change notifications for both Ethereum and Bitcoin transactions with a single, consistent API.

Support Custom Derivation Paths On Hardware Wallets

Easily Support Custom Derivation Paths for Ledger and Trezor Wallets

While you can hold every private key in the palm on your hand, there are a staggering number of possible wallet addresses that can be generated from a seed phrase. And  advanced users may take advantage of these possibilities by using custom derivation paths on their hardware wallets to select new addresses. 

The ability to choose a custom derivation path is popular among developers (who need to access test nets) and whales (who have many accounts that they use to secure funds). And support for hardware wallets and custom derivation paths is a commonly requested feature for leading applications.

Having a native hardware wallet integration was the most requested feature for the 
Gnosis Safe multisig. Thanks to Blocknative, we were able to deliver an easy and trusted way to use a Ledger or Trezor device with a multisig using Onboard.js.

The latest release of Onboard.js enhances our hardware support module, adding the ability to choose from common derivation paths or enter a custom derivation path. Read on to learn about what custom derivation paths are and why supporting them matters.

Does Your Web3 App Support Hardware Wallets?

Chris Meisl

By Chris Meisl in blockchain, onboard.js on March 12, 2020

Hardware wallets — such as Ledger and Trezor — are popular among crypto whales and traders. They provide an additional safeguard for digital assets. But that extra layer of protection presents a challenge for Web3 developers — as hardware wallets do not have any built-in user interface for selecting, viewing, and switching accounts or networks. 

Before now, if you wanted your product to support hardware wallets, you had to build a custom user interface from scratch. This takes serious time and effort.

Thankfully, those days are gone!

We are excited to introduce the latest update to Onboard.js — Blocknative’s open-source user onboarding framework. A new hardware wallet module makes it easy to add support for hardware wallets for users of your Web3 application.

Internal Transaction Monitoring Is The Missing Puzzle Piece To Understanding Your Smart Contract Activity

Chris Meisl

By Chris Meisl in blockchain, Notify, Mempool on February 13, 2020

Blockchains are transaction engines, enabling the exchange of value in ways that have not been possible before. The potential is exciting. But the complexity of smart contract-based transactions can make it difficult for even the most experienced Ethereum developers to understand what is actually going on with a transaction.

Today, we are excited to announce that Notify — Blocknative’s real-time blockchain transaction management and monitoring platform — now makes it easier to understand value transfer with support for internal transactions.

Announcing Onboard.js — Web3 User Onboarding Made Easy

Chris Meisl

By Chris Meisl in blockchain, usability, onboard.js on December 12, 2019

Transactions are key to every Dapp. But for your users to transact, they must have a wallet, connect to the right network, and have some ETH. There is a lot of room for error. If your users struggle to transact, this reflects poorly on your Dapp.

Given the above, it is crucial for you to provide users with clear directions. You cannot rely on wallet UX alone to ensure that your users transact successfully.

But you are in luck. Blocknative has built a robust open-source solution that helps transact on Web3.
