The mempool in blockchain networks is a temporary storage area for unconfirmed transactions. Mempool contains all unconfirmed transactions waiting to be included in a block by miners or validators, indicative of network activity and congestion.

Mempool, stored in each blockchain node, contains unconfirmed transactions. While anyone can run a node and access its mempool, visibility is limited. Bitquery APIs, connected to hundreds of nodes operated by validators and miners, provide more comprehensive mempool data, offering better insight into unconfirmed transactions network-wide.

Bitquery currently provides mempool information for EVM chains like including Ethereum, BNB and other chains like Tron

People with access to mempool data can time their trades based on the visibility of pending transactions affecting asset prices upon confirmation. They anticipate shifts by setting real-time alerts on transactions from specific wallets or above a certain amount.
