The mempool is often referenced as a waiting room for pre-chain transactions, but “waiting room” is too passive of a term. It suggests it’s a casual place for transactions to hang out while they wait to be confirmed on-chain. In reality, it’s more like abattle zone. Bots can force their way in to exploit arbitrage opportunities. Transactions can change out of sight, leaving you and your traders unprepared for battle. Traders are your end-users, so you are building for them. The more attractive you can make your product, the more traders you will have transacting on your Dapp (decentralized ap ..read more

Gas prices are a major source of transaction anxiety for both new and experienced Ethereum users. Accurately setting transaction fees is a classic Goldilocks problem:  ⏳ If you set your gas price too low, you lose transaction predictability, and you can wait hours – or days – or weeks! – for confirmation. Not to mention the risks of a stuck wallet.  ? If you set your gas price too high, you overpay and reduce your profitability.   So, how do you set your gas fee just right and get predictable transaction performance without overpaying? Recently, our CEO Matt Cutler sat dow ..read more

This essay was originally published on Bankless. Every pending Ethereum transaction invisibly competes in the mempool to be confirmed. While the mempool is a critical piece of blockchain infrastructure, many (most?) people have little understanding of how the mempool game works – or how the rules can be used against your best interests. Are you waiting for your transaction to confirm? That’s the mempool. Are you priced out by high gas fees? That’s the mempool too. Are you frustrated by a stuck transaction that has blocked your wallet? Yep…the mempool. Are you confused b ..read more

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 f ..read more

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 ..read more
