transactions

Kaia transaction types include legacy, value transfer, value transfer memo, smart contract deploy and execution, account updates, and cancels. They differ from Ethereum's simpler model by requiring an explicit from field and utilizing AccountKey-based signature validation across 20+ variants.

To classify a Kaia transaction, identify its exact type from the 20+ variants and check whether fee delegation applies. You must then list the required AccountKey-based signatures, noting that fee-delegated transactions utilize dual-signature patterns.

Full fee delegation in Kaia transactions requires dual-signature patterns where the fee payer covers all costs, whereas partial fee delegation splits the fee responsibility. Both variants apply across multiple transaction types like value transfer and smart contract execution.

Yes, Kaia transaction validation requires an explicit from field for AccountKey-based signature checks. This is a mandatory component across all transaction types, distinguishing Kaia's validation logic from Ethereum's simpler transaction model.

Yes, this handles fee-delegated smart contract execution transactions by classifying the exact type, parsing the transaction structure, and explaining the dual-signature validation requirements needed for reliable construction and processing.

Kaia transactions fail signature validation if the sender's AccountKey does not match the provided signature type. Account update transactions must be processed to change the key type before standard value transfer or smart contract execution can succeed.
