Terms that start with “U”

1. Unconfirmed Transaction

   An Unconfirmed Transaction refers to a blockchain transaction, such as buying, selling, or transferring a cryptocurrency, that hasn’t been permanently recorded to the blockchain. An unconfirmed transaction status means that the network of miners or validators hasn’t completely examined the transaction in full, to determine that there aren’t any pending transactions involving the same cryptocurrency being used.

2. Uniswap

   Uniswap is currently the largest decentralized exchange (DEX) by trading volume operating on the Ethereum blockchain, which allows anyone to swap ERC20 tokens. Uniswap was the pioneer in using the automated market maker model, where users supply Ethereum tokens to liquidity pools, and algorithms determine how to price assets.
