https://announcements.bybit.com/article/discontinuation-of-tusd-as-collateral-and-borrowable-asset-blte5a71fefe65aa0e7/

Dear traders,

Regarding announcement: https://t.me/Bybit_API_Announcements/300, please also note the value of collateralRatio field from below two APIs is no longer useful due to the transition from a single conversion rate to a tiered collateral value ratio when the change is effective.

We will introduce a new endpoint to obtain tiered collateral value ratio.

Affected APIs:
Get Collateral Info
Get VIP Margin Data

Dear Users,

Due to a backend configuration error, certain API endpoints allow access using read-only API keys, which should not have been permitted. The affected endpoints include:
• Set Deposit Account
• Create Internal Transfer
• Create Universal Transfer
• Set Collateral Coin
• Batch Set Collateral Coin
• Modify Sub acct API Key

After this adjustment, requests to the above-listed endpoints using read-only API keys will be denied with the error code:
10005 – Permission denied, please check your API key permissions.

If your integration currently relies on read-only keys for these operations, please update your API key permissions accordingly before the scheduled change to ensure continued functionality.

This change will take effect on February 18, 2025, at 7:00 AM (UTC+0).

Dear traders,

Regarding announcement https://t.me/Bybit_API_Announcements/301, the new endpoint to obtain tiered collateral value ratio now is ready.

Please refer to api doc https://bybit-exchange.github.io/docs/v5/spot-margin-uta/tier-collateral-ratio

Dear trader,

To improve efficiency and performance, Bybit will be making changes to the Get Transfer Records endpoints due to the increasing volume of transfer records.

Before the change:
* If startTime and endTime are not provided, the API returns data from the past 30 days by default.
* There is no restriction on the startTime & endTime range when querying transfer records.

After the change:
* If startTime and endTime are not provided, the API returns data from the past 7 days by default.
* If only startTime is provided, the API returns records from startTime to startTime + 7 days.
* If only endTime is provided, the API returns records from endTime - 7 days to endTime.
* If both are provided, the maximum allowed range is 7 days (endTime - startTime ≤ 7 days).

Affected APIs:
V5 - Get Internal Transfer Records
V5 - Get Universal Transfer Records
V3 - /asset/v3/private/transfer/inter-transfer/list/query
V3 - /asset/v3/private/transfer/universal-transfer/list/query

Deployment timeline:
1. Accounts with UID ending in "0": 6AM UTC, April 15

Dear Traders,


Discontinuation of SLP as collateral and borrowable asset.

Bybit will be discontinuing SLP as a collateralizable or loanable asset from Apr 10, 2025.

Please check the details below:
https://announcements.bybit.com/article/discontinuation-of-slp-as-collateral-and-borrowable-asset-blt7be16cc0532403c8/

Dear Traders,

Due to the increasing volume of data from large accounts, the /v5/account/transaction-log query frequently experiences timeouts, placing significant strain on our system. To mitigate this, we've decided to change the default query range from 7 days to 24 hours.

Before this change: startTime and endTime are not passed, return 7 days by default
After this change: startTime and endTime are not passed, return 1 days by default

This change is currently expected to be available on the testnet on 2025/04/17 and on the mainnet on 2025/04/25.


Please refer to API doc:
https://bybit-exchange.github.io/docs/v5/account/transaction-log

Dear Traders,

Announcement: Upcoming Institutional API Rate Limit Policy
Bybit will introduce a unified rate limit cap of 60,000 transactions per second (TPS) per product line (Futures, Options, Spot). This cap applies independently by business line, allowing institutions to allocate limits flexibly across all UIDs under their structure.

Features:
• Supports tier upgrades and downgrades, with proportional scaling to ensure compliance when limits are exceeded
• Backend-assisted configuration during rollout
• Custodial structures supported: institutional cap applies across all accounts (parent and sub accounts)


The new policy is expected to launch next quarter. If you have any questions or concerns, please contact your Bybit RM within two weeks.

Dear Traders,
We would like to inform you of an upcoming change to the SPOT order price logic.

Current Behavior (Before the Change):
If a user places a limit order with a price that crosses the opposite side of the order book:
• Buy order price > system calculated maximum limit price for buy orders
The system rejects the order with: "retCode": 170193, "retMsg": "Buy order price cannot be higher than XXXX USDT."
• Sell order price < system calculated minimum limit price for sell orders
The system rejects the order with: "retCode": 170194, "retMsg": "Sell order price cannot be lower than XXXX USDT."

New Behavior (After the Change):
If such orders are submitted:
• Buy order price > system calculated maximum limit price for buy orders, The system will automatically adjust the order price to that maximum limit price
• Sell order price < system calculated minimum limit price for sell orders. The system will automatically adjust the order price to that minimum limit price.
No error will be returned. The order will proceed with the adjusted price.

Deployment Schedule:
• 2025.06.02 — Rollout to Mainnet-Grayscale
• 2025.06.16 — Rollout to Mainnet-Full

Dear Traders,
