From Stablecoins to Crypto Dollars

From Stablecoins to Crypto Dollars

Earlier this year, we asked When One Billion ETH Transactions? And as part of our focus on transaction growth, we began digging into the global stablecoin market — which is now sustaining >$1 billion per day in transaction value. 

To better understand the growth of the global stablecoin market, we leveraged data from Coin Metrics to create a new report:

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.

Deploying Value On-Chain With Gold-Backed NFTs

Blocknative

By Blocknative in blockchain, usability, Case Study, Dapp, DeFi, Notify on April 15, 2020

What would coin collecting look like in the digital world? 

Jesse Johnson became obsessed with answering this question. And after he co-founded Mintable — a platform that makes it easy to mint and manage NFTs — he set to work to answer that question. 

Given his background in NFTs (non-fungible tokens), Jesse wanted to explore the idea of NFTs with intrinsic value. This eventually led to the creation of Bullionix — a decentralized gold mint where anyone can use Digix gold tokens to create NFTs. EachNFT minted on Bullionix has a specific weight of gold staked to it. Bullionix is the first crypto project to combine scarce NFTs with digital gold.

Support Custom Derivation Paths On Hardware Wallets

Easily Support Custom Derivation Paths for Ledger and Trezor Wallets

Chris Meisl

By Chris Meisl in blockchain, onboard.js on April 1, 2020

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.

Lukas Schor, Product Manager For Gnosis Safe

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.

Mastering the Mempool

8 Lessons to Help You Master the Mempool

We want to wish the entire community well during the COVID-19 pandemic. While things are turbulent right now, we wanted to share a new post that dives deep into the mempool so that you can dig into an important part of the Web3 ecosystem.


Blockchains are transaction machines. But on-chain data represents value-at-rest — confirmed transactions. While pre-chain, or mempool, data explores value-in motion — transactions in flight. 

To date, the industry has largely focused on value-at-rest. This is an important piece of the Web3 puzzle. But for any transaction to be included in a block, it must move through the mempool. And unlike the blockchain — which acts as a definitive record — the mempool is chaotic, fragmented, and often unpredictable. 

In the course of building infrastructure to monitor the mempool, we've learned a lot about how it works. And at ETHDenver 2020 Matt Cutler, Blocknative's CEO and co-founder, shared some important lessons in his talk Mastering the Mempool:

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.

When will ethereum reach 1 billion transactions?

When One Billion Ethereum Transactions?

Web3 is taking root — transitioning from proof-of-concepts to enterprise-grade solutions. As specialists in the global mempool and the associated value in motion, the team at Blocknative looked back at 2019 and wondered, "How many public blockchain transactions have ever happened?" This quickly lead to "How many new public blockchain transactions can we reasonably expect in the coming years?" 

We were surprised that, as far as we could tell, no one had previously published answers to either of these questions. So we set off to generate our own results. And today we're happy to share our findings.

The results were surprising, exciting, and encouraging.

How Defi Saver Makes It Easy To Manager Assets In Web3

DeFi Saver: Making It Easier To Manage DeFi Assets

Blocknative

By Blocknative in blockchain, usability, Case Study, Dapp, DeFi, Notify on February 18, 2020

DeFi is a blockchain term that refers to decentralized finance, and the ethos of the term refers to the creation of an open financial system that doesn’t rely on authorities or intermediaries. Today most DeFi activity is on the Ethereum network and ranges from digital assets to financial smart contracts to protocols.

With DeFi, developers can program applications that can store, lend, borrow, or otherwise manage digital assets. These applications often come to life in the form of smart contracts or protocols — which can be leveraged by other developers to build on. 

Today we will explore this emerging world that seeks to reinvent the financial system.

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.

Nodes, Your Gateway To The Mempool

A Note On Nodes: Your Gateway To The Mempool

Nodes act as a gateway to the Ethereum network. Before a miner can include your transaction in a block, a node must first accept it. And understanding how nodes accept transactions can unlock insights into how Ethereum works.

Our goal with this Mastering the Mempool series is to help you understand this crucial — but often under-explored — element of Web3. We suggest starting with our first post in the series, where we cover many of the core concepts of the mempool. 

In this post, we explore how transactions enter the Ethereum mempool.
