Supported Instruments (RFQ)

To programmatically retrieve the latest instruments available for Request for Quote (RFQ) trading, you can query the GET /assets endpoint. In the response, look for assets where "rfq_liquidity_enabled": true, this field indicates whether the asset is currently supported for RFQ trading.

Deposits and Withdrawals

• All fiat assets are supported for institutional deposits and withdrawals.
• Zero Hash does not support fiat deposits and withdrawals from retail end users.
• All crypto assets support withdrawals for retail end users.

Smart Contracts

Smart Contracts are currently supported for:

• Avalanche C-Chain (AVAX)
• Ethereum Classic (ETC)
• Ethereum (ETH)
• Ethereum on Arbitrum (ETH.ARBITRUM)
• Ethereum on OP Mainnet (ETH.OPTIMISM)
• Polygon (MATIC.POLYGON) using ABI encoding.

Rounding

If you are utilizing the Zero Hash API to calculate trade notional and settlement values, banker's rounding must be used on a per-trade basis.

• The Zero Hash settlement system will round each trade obligation and then sum at the end, vs. summing all trade obligations and then rounding the final value.
• Banker’s rounding is also known as Round to Even.

Rules:

1. If the difference between the number and the nearest integer is less than 0.5, round to the nearest integer.
2. If the difference between the number and the nearest integer is exactly 0.5, look at the integer part of the number and round to the nearest even integer.

Example:

You submit a BTC/USD trade:

• Quantity: 10 BTC
• Price: $10,000.0008 per BTC

Initial calculation:
10 × 10,000.0008 = 100,000.008 USD

USD payments are restricted to cents, so this is rounded to:
$100,000.01

Support for Participants in New York

• The New York Department of Financial Services (NYDFS) maintains a list of NYDFS pre-approved tokens for New York customers, the Greenlist.
• Although NYDFS categorizes asset support into:
  • Approved for Custody
  • Approved for Listing
    Zero Hash only supports assets that meet both criteria.
• As a result, there may be assets available for one or the other according to NYDFS, which Zero Hash will not support for Participants in NY.
• All supported assets for NY are marked with 'Yes' in the Supported in NY column in the above table.
