Our repository of articles on DeFi. On Ethereum, when a transaction is sent, before being added to a block, it resides in what is called a Mempool. To receive information about this transaction, the Mempool must be queried. This guide will demonstrate how to query a node’s mempool using QuickNode Ethereum INSTANT XDAI API ACCESS ON QUICKNODE The fastest way to build on the world's most popular blockchains: Ethereum, Polygon, Bitcoin, Optimism, BSC & xDai.

CREATING A RESTFUL API FOR COMPOUND FINANCE SMART There is some Compound specific vocabulary we need to understand before we go about building our API. This is not an all encompassing glossary, if you'd like more in depth explanations, go check out the compound finance documentation on cTokens, but here is the basic terminology to get us started: cTokens: HOW TO CREATE YOUR OWN ORACLE WITH AN ETHEREUM SMART The Ethereum blockchain network is a cluster of nodes that execute smart contracts. To obtain the same consistent outcome, all nodes must have access to the same set of inputs, and this is called determinism. HOW TO RE-SEND A TRANSACTION WITH HIGHER GAS PRICE USING An ordinary transaction, when there is a transfer of ETH/ether from one account to another. A transaction creating a contract is the type of transaction where a smart-contract in deployed on the Ethereumblockchain network.
