Account Creation

This document covers the transaction logic required to create accounts on the Flow blockchain. Read the accounts & keys documentation for an overview of the Flow account model.

Batch Account Creation

A single transaction can create multiple accounts by making multiple calls to the AuthAccount initializer.

Due to current transaction limits, accounts should not be created in batches larger than 20 accounts.

The examples below emit the same flow.AccountCreated event as a normal account creation transaction. However, rather than emitting a single event, these transactions emit one event for each new account.

Check out this page to see how account creation transactions and events work in Go: Create an Account with the Go SDK.

Unique Key For Each Account

transaction(publicKeys: [String]) {
  prepare(signer: AuthAccount) {
    for publicKey in publicKeys {
      let account = AuthAccount(payer: signer)
      account.addPublicKey(publicKey.decodeHex())
    }
  }
}

Same Key For All Accounts

transaction(publicKey: String, count: Int) {
  prepare(signer: AuthAccount) {
    var i = 0
    while i < count {
      let account = AuthAccount(payer: signer)
      account.addPublicKey(publicKey.decodeHex())
      i = i + 1
    }
  }
}
