Overview
Supported exchanges
We support the following exchanges for the Fireblocks Off Exchange feature.
Supported assets
Not all assets supported by an exchange can be accepted by the exchange as collateral. In the exchange sections below, you can find the assets supported as collateral by each exchange.
If you accidentally send unsupported assets to your CVA:
- The exchange should not credit you for these assets.
- You should be able to withdraw these assets from your CVA. If removing the collateral fails, you must ask the exchange's support team to confirm the collateral removal request.
- Contact Fireblocks Support if needed.
Settlements
Exchanges are responsible for calculating settlements and sending settlement instructions to Fireblocks containing the transactions to and from CVAs. The settlement process may vary between exchanges in the following parameters:
- Settlement calculation: Gross/Net
- Settlement cycles: Each exchange defines the duration and timing of each settlement cycle. Additionally, an exchange can determine whether you are allowed to request ad-hoc settlements.
- Settlement approval SLA time: The time provided to you for reviewing and approving/signing settlement transactions before they are sent to the exchange for auto-approval by the collateral signer.
- Settlement review SLA time: The time provided to you to manage a dispute in case of rejection/failure before the transaction is sent for forced settlement by the exchange's collateral signer.
Settlement threshold
A settlement threshold is the minimal amount above which a settlement request is sent. Any balance under that threshold does not warrant settlement.
Deribit Off-Exchange parameters
Supported account types
The Deribit Main account can be set up for off-exchange. Balance calculation for settlements will include all the Main account's sub-accounts. The user should configure the sub-accounts on the Fireblocks exchange connection to see the distribution of assets between the main and sub-accounts.
There is no limitation on the types of products available when using the Fireblocks off-exchange settlement. However, negative balances of any currency are restricted when using the cross-collateral margin mode. When a currency balance goes negative, we execute a cash rebalancing spot trade to cover the shortfall from another available currency. This limitation will be addressed towards the end of Q1 2025 to allow clients to take full advantage of the cross-collateral margin mode.
Account Level integration
The connection takes place on the main account level, but includes all sub-accounts.
Specific API user configuration
To establish the exchange connection on Fireblocks, the API key created on Deribit should have the following scopes:
- Account: Read/Write
- Wallet: Read/Write
- Custody: Read/Write
For the 2FA configuration, the long alphanumeric code above the QR code on Deribit's UI should be used instead of the 6-digit 2FA code. This code is visible only at the time of creation and cannot be retrieved later on.
Exchange balance reflection
The Fireblocks UI has three columns:
- Available amount: The balance available for opening new positions/withdrawable
- Collateral amount: The CVA on-chain balance
- Credit amount: The mirrored amount on Deribit from the collateral in the CVA
Default credit limits for onboarding customers
During the onboarding phase, a default CVA limit of 0.09 is imposed to avoid triggering settlements, as the settlement threshold is 0.1.
When going live, a suitable approach is discussed with each customer. You can decide to store all assets in the CVA at once or gradually increase your CVA limits.
Refer to Deribit's supported tokens table here.
By default, the settlement threshold for each currency is 0.1, but it can be customized per user per token by request.
Settlement process
Internal calculations run daily between 8.00-8.05 AM UTC to close out the previous trading session (the previous 24 hours). A settlement request is sent daily to Fireblocks at 8.30 AM UTC.
- Losses have a two-hour review window (From your CVA to Deribit). If a transaction is approved during the review window, it settles. If it is rejected within the review window, you can dispute the review with Deribit for investigation. Otherwise, the transaction will automatically settle 23 hours after the original settlement initiation. This is typically at 7.30 AM UTC the following day. If no action is taken, the transaction auto-settles at the end of the review window, typically at 10.30 AM UTC.
- Profits have a 23-hour review window (from Deribit to your CVA). If a transaction is approved during the review window, it settles. If it is rejected or no action is taken, the transaction expires on Deribit, and Deribit initiates a new updated settlement amount during the next cycle.
Who can trigger settlements?
Only the exchange, per its cycle.
Gas management
10% of ETH deposits are reserved for gas, with a cap of 0.01 ETH. Reserved gas fees may be manually altered by Deribit admins if required.
Settlement window
Settlement cycles
Once a day at 8.30 AM UTC. However, you have no limitation on accessing your funds between two settlements. Any withdrawal request goes through a real-time balance examination and is approved if funds are available to withdraw.
Settlement approval SLA time
For CVA > Deribit:
- Two-hour review window until 10.30 AM UTC.
- Auto-settlement at 10.30 AM UTC if no approval/rejection takes place.
- If rejected: marking as a candidate for forced settlement at 7.30 AM UTC+1
For Deribit > CVA:
- 23-hour review window.
- If approved, the settlement transaction is generated at the time of approval.
- If rejected or nothing done: instructions expire at 7.30 AM and new instructions with an updated amount are sent at 8.30 AM.
Settlement Review SLA time
As explained above.

- Fee deduction transaction log on Bybit will be: CUSTODY_NETWORKFEE (Custody Network Fee). This transaction type is the same as the custody unlocking fee.
For Bybit > CVA:
- CVA will receive the net amount, and Bybit records transaction fees for users (method of collection to be determined).

Gate Off-Exchange parameters
Supported account types
Gate supports Unified (Multi-currency trading) accounts, which allow trading across spot, futures, and margin from a single account.
Account level integration
The connection must be established with Gate's main account.
Sub-accounts are supported and can be configured after the main account is connected.
Specific API user configuration
To establish the exchange connection on Fireblocks, the API key created on Gate must have the following Read/Write permissions:
- Spot Trade
- Perpetual Futures
- Delivery Futures
- Wallet
- Custody
- Withdraw
- Broker
- Option
- Commission Details
- Margin Trading (Unified Account)
- Loan
To create an API key, go here.
During the connection process, collateral signer pairing is required.
Exchange balance reflection
The Fireblocks UI displays three columns:
- Available amount: Gate's transferable amount
- Collateral amount: The on-chain CVA balance (including Gate's settlement margin requirement)
- Credit amount: The total wallet balance across Gate's main account and sub-accounts
Credit limits
Gate does not define a fixed default credit limit for onboarding customers according to the documentation provided by the exchange. Credit limits are determined operationally during onboarding and collateral setup.
Supported assets
Gate supports multiple assets as collateral, including but not limited to:
| Settlement Currency | Chain | Gas fee token | Minimum amount |
| BTC | Bitcoin | BTC | 0.0002 |
| ETH | Ethereum | ETH | 0.01 |
| OXT | Ethereum | ETH | 1250 |
| FET | Ethereum | ETH | 50 |
| BOBA | Ethereum | ETH | 500 |
| ACX | Ethereum | ETH | 250 |
| SAFE | Ethereum | ETH | 120 |
| USDT（ERC） | Ethereum | ETH | 10 |
| ULTIMA | Ethereum | ETH | 0.01 |
| USDC | Ethereum | ETH | 10 |
Multiple blockchains may be supported per asset. You can configure the settlement blockchain in their Fireblocks Console (by adding collateral).
Once collateral is added and bound, the settlement blockchain is assigned to that currency. If multiple chains are available, the cheapest chain (by gas fee) is automatically selected for settlement
Supported chains per asset can be queried via Gate's API here.
Note: Gate.io maintains a safety buffer on collateral balances. Your exchange view balance may appear lower than your collateral workspace balance by $100 equivalent per alt-coins, and up to $150 equivalent for BTC/ETH.
Settlements
Settlement process
When a settlement is triggered, Gate performs settlements in both directions:
- CVA > Gate
