All transactions on the Ethereum blockchain (known as on-chain transactions) go through the following 4 main stages.
User Confirmation— Signing a transaction with the wallet’s private key
Broadcasting — Broadcasting the signed transaction on the blockchain
Mining — Waiting for the transaction to be mined by Ethereum miners
Completion — Success or Failure
Due to the immutable nature of the blockchain, once the transaction is completed (Step #4), it can’t be changed. Krystal trades are performed fully on-chain on Ethereum, so all successful transactions also follow these 4 stages.
