What Is a Transaction?
A transaction (TX) is the transfer of cryptocurrency from one wallet address to another, recorded on a blockchain’s distributed ledger. When a user initiates a transaction, funds are sent from a public address and authorized using a private key, which proves ownership of the assets being transferred.
Crypto transactions rely on cryptography to encrypt transaction data before it is broadcast to the network. While transaction details such as the amount and wallet addresses are publicly visible, the identities behind those addresses remain anonymous. Transactions are decentralized, meaning no central authority or bank controls or approves them.
Multiple transactions are grouped together into blocks, which are added to the blockchain by miners or validators. The time it takes for a transaction to be confirmed depends on network congestion and the transaction fee paid. Users can track transaction status using a block explorer.
On KAST, transactions power card top-ups and payments, letting users verify transfers on-chain and spend crypto seamlessly once confirmations are complete.
