# Stock Split

> Execute a stock split or reverse split on a token

Executes a stock split by adjusting all holder balances according to the provided ratio. A `numerator` of 2 and `denominator` of 1 is a 2-for-1 forward split. A `numerator` of 1 and `denominator` of 2 is a 1-for-2 reverse split.

The `numerator` and `denominator` must both be positive integers and cannot be equal.

## Path Parameters

<ParamField path="tokenAddress" type="string" required>
  Address of the stock token contract.
</ParamField>

## Request Body

<ParamField body="numerator" type="integer" required>
  Split ratio numerator. Must be a positive integer.
</ParamField>

<ParamField body="denominator" type="integer" required>
  Split ratio denominator. Must be a positive integer and different from `numerator`.
</ParamField>

## Response Fields

<ResponseField name="data" type="object">
  <Expandable>
    <ResponseField name="success" type="boolean">Calldata was built successfully.</ResponseField>

    <ResponseField name="txData" type="object">
      The unsigned transaction. `to` is the token contract, `data` is the encoded `stockSplit` call, and `value` is always `"0"`.
    </ResponseField>
  </Expandable>
</ResponseField>

<Note>
  Nothing is submitted on your behalf. Sign `txData` with a wallet holding the required role on the token and broadcast it yourself.
