Getting the asset list

Call the Retreive supported assets endpoint to view the list of assets available to your workspace. The response includes the Fireblocks assetId which is used when you add assets.

If you're looking into quickly viewing the supported asset list, you can view the Supported Networks page.

Adding assets

You add assets via the Fireblocks SDK. Unless your Fireblocks Customer Success Manager and Fireblocks Support allow an exception, Fireblocks requires you to complete the backup procedure for each wallet before you can add any assets.

A note on Backup Enforcement

If your workspace is already running in a Production environment, key backup enforcement is enabled by default. However, it is not enabled by default in Sandbox environments to allow for an easier integration process.

Due to the above, when you attempt to call the Active a wallet in a vault account endpoint, you must first go through this backup flow.

Example

const address = await this.clients.signer.NCW.activateWalletAsset(  
      walletId,  
      accountId,  
      assetId,  
    );

curl --request POST \
     --url https://sandbox-api.fireblocks.io/v1/ncw/wallets/walletId/accounts/accountId/assets/assetId \
     --header 'accept: application/json'

Note in the code example above that the accountId parameter runs an index created by the await admin.NCW.createWalletAccount(walletId) function. In our demo, we always use accountId 0 for simplicity.

Adding Solana Tokens

On the Solana blockchain, receiving tokens requires creating a dedicated token account derived from your main account. This is usually handled automatically when someone sends you tokens, but your customer can pre-create the account if needed.

In order to create the dedicated token account, you can still invoke the add asset endpoint which in turn will create a transaction on behalf of the customer, for signing.

Within the response of the request, or later on, using the retrieve asset endpoint you can query for the state of the asset.

• PENDING_ACTIVATION
• ACTIVATION_FAILED
• READY

In case the asset is under PENDING_ACTIVATION, a pending transaction still awaits the end user for signing. Once he signs the transaction, the asset status should now appear as READY.

In case the end user failed to sign the transaction, the status will appear as ACTIVATION_FAILED and the asset will require adding it again.
