Gate.io plans to conduct a system upgrade for API v4 on February 27, 2025, at 07:00 (UTC). This upgrade will introduce new fields and deprecate certain existing fields in the GET /spot/currencies and GET /spot/currencies/{currency} API endpoints. During the upgrade, API users can continue to use API v4 as usual.
After the upgrade, users will be able to query the newly added names, deposit and withdrawal statuses, contract addresses, and other information of spot currencies through GET /spot/currencies or GET /spot/currencies/{currency}.
The main changes are as follows:

1. The original fields withdraw_disabled, withdraw_delayed, and deposit_disabled will be deprecated in the GET /spot/currencies and GET /spot/currencies/{currency} endpoints.
2. A new array-type field, chains, will be added to the GET /spot/currencies and GET /spot/currencies/{currency} endpoints.
3. The GET /spot/currencies and GET /spot/currencies/{currency} endpoints will return all chains corresponding to the currency along with their deposit and withdrawal statuses, eliminating the previous {currency}_{chain} format.

Below is a comparison of the response examples before and after the upgrade, using BTC as an example:

Example response before the upgrade is as follows:
{
“currency”: “BTC”,
“delisted”: false,
“withdraw_disabled”: false,
“withdraw_delayed”: true,

},
{
“currency”: “BTC_HT”,
“delisted”: false,
“withdraw_disabled”: true,
“withdraw_delayed”: false,
“deposit_disabled”: true,
“trade_disabled”: true,
“chain”: “HT”
}

Example response after the upgrade is as follows:
{
“currency”: “BTC”,
“name”: “Bitcoin”,
“delisted”: false,
“withdraw_disabled”: false,
“withdraw_delayed”: false,
“deposit_disabled”: false,
