Read-only API access lets a tool view balances, positions, and trade history with no ability to place an order or move funds; trade permission adds the ability to open and close positions; withdrawal permission adds the ability to move funds off the exchange — and the difference between the three is the difference between a leaked key being an inconvenience or a total loss.

Key takeaways

• Most exchanges separate API key permissions into distinct toggles — read, trade, and withdrawal — and a tool should only ever request the permissions it actually needs.
• A leaked read-only key exposes account data but cannot place an order or move funds; a leaked trade-enabled key can be used to open, close, or manipulate positions.
• Withdrawal permission is the most dangerous scope to grant any third-party tool, since it allows funds to be moved out of the account directly.
• A tool's marketing claim of being "read-only" should be verified against the actual permission scope granted when the key was created, not assumed.
• IP whitelisting, where the exchange supports it, further limits a leaked key even within its granted permission scope.
• DRKN's Toobit connection requests read-only access only; it never requires trade or withdrawal permission for account review.

What each permission scope actually allows

Exchange API systems typically expose three separate toggles when a key is created. Read permission allows a connected application to view balances, open positions, and trade history — enough for account review, but not enough to change anything. Trade permission adds the ability to place, modify, and cancel orders, which means a compromised key with this scope can alter the account's actual positions and risk. Withdrawal permission adds the ability to move funds off the exchange entirely, independent of trading activity — the most direct path from a compromised key to a lost account.

A worked example: the same leak, three different outcomes

Consider a 5,000 USDT account and the same leaked API key under three different permission scopes. With read-only permission, the leak exposes balances, open positions, and trade history to whoever obtained the key — a real privacy concern, but funds and positions remain exactly as they were, since the key cannot place an order or move anything.

With trade permission added, the same leak allows the holder to open new positions, close existing ones, or place intentionally damaging trades — potentially driving the account toward a large loss or liquidation even though withdrawal itself is disabled. With withdrawal permission added on top, the holder can simply move the 5,000 USDT out directly, which is both faster and more complete than achieving a similar loss through trading activity alone. The permission scope, not the strength of the password protecting the exchange account, determines how bad a single leaked key can actually be.

How a read-only key actually leaks in practice

The permission scope matters because the leak vectors are mundane, not exotic. A key pasted into a public GitHub repository, stored in plain text in a spreadsheet shared with a group chat, or entered into a copy-trading tool that turns out to log requests are all realistic ways a key ends up outside the trader's control — none of them require a sophisticated attack. This is exactly why the permission scope granted at creation matters more than how carefully the key is guarded afterward: a trader who is careful for months can still have one moment of carelessness, and the permission scope determines what that single moment actually costs. A read-only key pasted into the wrong place is a data exposure that can be fixed by rotating the key. A trade-enabled key pasted into the wrong place can be an active, damaging position by the time the trader notices the mistake. Treat every API key as if it will eventually be seen by someone it should not be, and grant only the permission that stays safe under that assumption.

Common mistakes with API permissions

• Granting trade or withdrawal permission to a tool that only needs to read account data, often because it was the default option during key creation.
• Assuming a tool's claim of being "read-only" is accurate without checking the actual permission toggles granted on the exchange's own key management page.
• Not using IP whitelisting where the exchange supports it, which would further limit a leaked key even within its granted scope.
• Reusing one API key across multiple tools instead of issuing a separate key per tool, so a problem with one connection does not expose every other one.
• Never rotating or revoking keys that are no longer in active use, leaving old permissions active indefinitely.

Two traders, same exchange

• Trader — Scoped, dedicated keys: Issues a read-only key with IP whitelisting specifically for account-review tools, and keeps trade-enabled access limited to manual browser sessions — Result: a leaked review-tool key exposes data only, with no ability to affect positions or funds.
• Trader — One all-permission key: Uses a single API key with trade and withdrawal permission across every connected tool for convenience — Result: any one compromised connection can affect the entire account, regardless of which tool leaked the key.

Apply this to your account: Ask DRKN to help you review what a read-only connection can and cannot do before granting it. DRKN's Toobit connection uses read-only permission only, on your live account. DRKN provides educational risk guidance only — it never requests trade or withdrawal permission and does not place orders for you.

Where DRKN's account view fits

DRKN's Toobit connection requests read-only access specifically because account review does not require the ability to place orders or move funds — the permission scope matches the function. See Toobit API key checklist before connecting DRKN for the practical steps to verify a key's scope, and why bots and risk tools need separate API keys for why one key per tool matters even when every individual scope looks reasonable.

Frequently asked questions

Does DRKN ever need trade permission?

No. DRKN reviews account data and provides risk guidance; it does not place, modify, or cancel orders, so read-only permission is all it ever requests or needs.

What if I accidentally grant trade permission when connecting a tool?

Most exchanges let you edit or revoke an API key's permissions after creation. Check the key's current scope on the exchange's key management page and remove any permission the connected tool does not actually require.

Can a read-only key still see my account balance?

Yes. Read-only permission is designed specifically to allow viewing balances, positions, and trade history — that visibility is what makes account review possible without granting the ability to change anything.
