Kaia Account

When you are developing a blockchain application, chances are that it will be submitting transactions to the blockchain. The entity that sends the transactions are Accounts. On Kaia, your accounts are called EOA, or externally owned accounts. Whether you are sending a transaction to Kaia with Wallet API or retrieving token transaction history using Token History API, you need a Kaia account.

Fee Delegation Account and Operator

Kaia can be divided into EOA (for storing, transferring, receiving KAIA) and a smart contract account which is created upon deploying a smart contract.

Account Pool

Your KAS account can own multiple Kaia accounts. KAS provides account repositories called account pools to store your Kaia accounts, so that you can manage multiple Kaia accounts using just a single KAS account. There are different pools depending on the account type. One KAS account may manage multiple pools. KAS currently provides the following types of pools:

• Default Account Pool : Repository for normal Kaia accounts
• Fee-payer Pool : Repository for feepayer accounts

Default Account Pool

This is the account pool that will be used when you don't designate a account pool for making KAS API requests. More specifically, if you don't enter a separate KRN (KAS Resource Name) of an account pool in the header's x-krn, the account in the default account pool will be used. You can find the default account pool in KAS Console > Service > Wallet > Account Pools with the DEFAULT tag.

The first account pool you create will automatically be the default account pool. Say you created an account pool A on KAS Console. That pool A will automatically be used when you make API requests. If you make an API request to create a Kaia account without having an account pool, KAS will automatically create it for you and store your account there.
