# Create Wallet: POST /dac/v1/create-wallet for an Asset

> Provision a new MPC wallet for a supported asset in your Finrock sub-account. Only one wallet is allowed per asset per sub-account.

The Create Wallet endpoint provisions a new MPC wallet for the specified asset within your sub-account. Finrock enforces a one-wallet-per-asset-per-sub-account limit, so this call is typically made once during initial onboarding for each asset you intend to support. Once provisioned, the wallet is immediately available for address generation and transaction submission.

## Request

<ParamField header="x-api-key" type="string" required>
  Your Finrock API key.
</ParamField>

<ParamField header="Authorization" type="string" required>
  Your JWT bearer token in the format `Bearer {JWT}`.
</ParamField>

<ParamField body="asset" type="string" required>
  The asset for which to provision a wallet. Use the `asset_name` value from the [Supported Assets](/api-reference/utilities/supported-assets) list (e.g. `ETH`, `BTC`, `USDT_ETH`).
</ParamField>

## Example Request

```bash cURL theme={null}
curl --request POST \
     --url https://api.finrock.io/dac/v1/create-wallet \
     --header 'Authorization: Bearer {JWT}' \

     --header 'content-type: application/json' \
     --header 'x-api-key: YOUR_API_KEY' \
     --data '{

<Note>
  Attempting to create a second wallet for an asset that already has one in your sub-account will return an error. Retrieve your existing wallet using [List Wallets](/api-reference/wallets/list-wallets) first.
