# Asset

#### defineAsset[​](https://wiki.findora.org/docs/developers/utxo/sdk-api/sdk_api_asset#defineasset) <a href="#defineasset" id="defineasset"></a>

***- Defines a custom asset***\
An asset definition operation registers an asset with the Findora ledger. An asset is a digital resource that can be issued and transferred.\
An asset has an issuer and a unique code. The DefineAsset operation must provide an unused token code. The transaction containing the DefineAsset operation will fail if there is already another asset on the ledger with the same code.

**Parameters:**[**​**](https://wiki.findora.org/docs/developers/utxo/sdk-api/sdk_api_asset#parameters)

* &#x20; `<WalletKeypar>` - Wallet keypair
* &#x20; `<string>` - asset name
* &#x20; `<string>` - (optinal) asset memo
* &#x20; `<string>` - (optinal) A set of rules (options) for the new asset.

**Results:**[**​**](https://wiki.findora.org/docs/developers/utxo/sdk-api/sdk_api_asset#results)

* &#x20; `Promise<TransactionBuilder>` - An instance of `TransactionBuilder` from `Ledger`

**Example:**[**​**](https://wiki.findora.org/docs/developers/utxo/sdk-api/sdk_api_asset#example)

```typescript
const walletInfo = await Keypair.restoreFromPrivateKey(pkey, password);

// First, we create a transaction builder
const assetBuilder = await Asset.defineAsset(walletInfo, assetCode);

// Then, we submit a transaction
const handle = await Transaction.submitTransaction(assetBuilder);
```

```

#### getFraAssetCode[​](https://wiki.findora.org/docs/developers/utxo/sdk-api/sdk_api_asset#getfraassetcode) <a href="#getfraassetcode" id="getfraassetcode"></a>

***- Returns the pre-defined FRA asset code***\
FRA asset code can not be re-defined, as well as it can not be used in the `DefineAset` or `IssueAsset` operations.\
This is the main asset code, which is used when user needs to create a transaction, or calculate the fee and so on.

**Results:**[**​**](https://wiki.findora.org/docs/developers/utxo/sdk-api/sdk_api_asset#results-3)

***- Issue some amount of a custom asset***\
Asset issuers can use the `IssueAsset` operation to mint units of an asset that they have created. Concretely, the `IssueAsset` operation creates asset records that represent ownership by a public key of a certain amount of an asset. These asset records are stored in a structure called a transaction output (TXO).

* &#x20; `<WalletKeypar>` - wallet keypair
* &#x20; `<string>` - asset name
* &#x20; `<string>` - amount to be issued
* &#x20; `<AssetBlindRules>` - asset blind rules
* &#x20; `<number>` - (optional) asset decimals. This parameter can define how many numbers after the comma would this asset have

* &#x20; `Promise<TransactionBuilder>` - An instance of `TransactionBuilder` from `Ledger`

**Example:**[**​**](https://wiki.findora.org/docs/developers/utxo/sdk-api/sdk_api_asset#example-7)

```typescript
const walletInfo = await Keypair.restoreFromPrivateKey(pkey, password);

// Define the new asset parameters (rules)
const assetBlindRules = { isAmountBlind: false };

// First, we create a transaction builder
const assetBuilder = await Asset.issueAsset(
  walletInfo,
  customAssetCode,
  amountToIssue,
  assetBlindRules
);

// Then, we submit a transaction
const handle = await Transaction.submitTransaction(assetBuilder);tyty
