The withdrawal fees may fluctuate based on how busy a blockchain network is. You can refer to the abs_estimate_fee field
of the GET /v1/custody/coin_info endpoint to check the estimated withdrawal fees associated with a Custodial Wallet.
For an MPC Wallet, please use the GET /v1/custody/mpc/estimate_fee/ endpoint instead.
What do amount and abs_amount stand for in the interface?
In the realm of cryptocurrencies, each coin possesses a smallest unit.
For instance, a satoshi is the smallest unit of Bitcoin. Each Bitcoin equals 100 million satoshis (i.e., 100,000,000).
Cobo denominates amount in terms of the smallest unit specific to each cryptocurrency to prevent complications associated with the misuse of floating point numbers.
If you transfer 1 Bitcoin, for instance, the amount will be displayed as 100,000,000 and the abs_amount will be 1.
This conversion is calculated using the formula: abs_amount = amount / pow(10, decimal).
How do I query the minimum deposit amount for a specific coin?
You can refer to the minimum_deposit_threshold field of the GET /v1/custody/get_supported_coins/
endpoint to query the minimum deposit amount for a specific coin within a Custodial Wallet. If the response returns a zero, it indicates that the there is no minimum deposit requirement for the selected type of coins. Note that coins held under an MPC Wallet do not have any minimum deposit requirements.
Why does the coin amount returned by the ‘org_info’ field of the API endpoint differ from the amount shown on the Cobo Custody Web dashboard?
The data returned by the org_info field of the API endpoint should match the balance of the corresponding coin in your wallet.
However, the coin balances displayed on the Cobo Custody Web dashboard (as seen in the first screenshot) are snapshots and may experience a delay of up to one hour.
If you need to query real-time balances, we recommend that you navigate to the specific wallet first and verify the balance of the corresponding coin within that wallet (as seen in the second screenshot).
