Add New Assets & Trading Pairs

You add coins under Operator Controls → Exchange → Treasury → Assets and trading pairs under Operator Controls → Exchange → Markets → Markets & Pairs. Which assets you can add, and how many, can depend on your plan; if the dialog shows an upgrade prompt, contact the HollaEx team.

Add a new coin already supported by HollaEx​

  1. Go to Operator Controls → Exchange → Treasury → Assets and click Add Asset.
  2. In Create Asset, open the Asset list and choose the coin, for example USDT or ETH. You can search by name or paste a token's contract address.
  3. Click Next, check the asset's details, and confirm.

The asset is added to your list. Users see it in their wallet once it's applied to the live exchange.

Add an asset that isn't listed yet​

Use this when the coin you want isn't in the list, or when you're creating your own token.

  1. In Create Asset, click Add your asset (under "Don't see your asset?").
  2. Search by name or paste the token's contract address. If it still isn't found, click Create a brand new asset.
  3. Under Select asset type, choose Blockchain. Some exchanges also see External wallet (crypto held in your own custody).
  4. Choose the network (for example Ethereum, Tron, BSC or Polygon) and the token standard (for example ERC-20), then enter the contract address.
  5. Under Naming and color, enter the asset name (for example "Tether") and symbol (for example "USDT"), and pick the asset's color.
  6. Add a short description, an icon and the number of decimal points.
  7. Set the asset's price and its parameters (minimum, maximum and increment amounts, and whether deposits and withdrawals are allowed). See Configure Asset Parameters.
  8. Review the details and confirm.

The new asset appears in your asset list marked as pending verification. Contact support@hollaex.com with your exchange name and the asset, and the HollaEx team will guide you through getting it activated.

If your blockchain isn't in the network list, contact support@hollaex.com to discuss adding it.

Add a fiat currency​

Fiat assets such as USD or GBP are added from the same Asset list. When you add one, Operator Controls reminds you that fiat currencies aren't on a blockchain: you are responsible for solvency, and you need a bank or payment system to handle deposits and withdrawals. Confirm with I understand, proceed, then set up deposits and withdrawals in Fiat Controls.

If the fiat currency you need isn't in the list, contact support@hollaex.com.

Add a trading pair HollaEx already supports​

  1. Go to Operator Controls → Exchange → Markets → Markets & Pairs, on the Public Markets tab.
  2. Click Create/add market.
  3. Select the market from the list. The list only shows pairs between assets on your exchange; to see more, add more assets first.
  4. Click Next, check the market parameters, and confirm.

The new market appears under Markets on this exchange.

Create a brand-new trading pair​

You can create a pair between any two assets on your exchange.

  1. Click Create/add market, then Create a new market.
  2. Under Base Asset, choose what will be traded. Under Priced, choose the asset it will be priced in. For example, base BTC priced in USDT gives the BTC/USDT market.
  3. Click Next. Under Market parameters, the values are preset from the rough dollar value of the base asset. Edit them if needed. See Configure Pair Parameters.
  4. Review the configuration and confirm.

The new market is listed under Pending markets until it's verified. Contact support@hollaex.com with your exchange name and the new pair to have it finalized. Once it's active, users can trade it on the order book.
