What is a Transaction?
A transaction is an action recorded on a blockchain, such as sending tokens, swapping assets, minting an NFT, or interacting with a smart contract.
Transaction Explained
A transaction is like a recorded action on a blockchain.
When someone sends crypto, buys an NFT, or uses a dApp, they create a transaction.
The blockchain checks that the transaction follows the rules, then adds it to its records.
Once confirmed, the transaction becomes part of the blockchain’s history and can usually be viewed on a block explorer.
