Prime Upcoming Changes

This page provides information about upcoming changes to Coinbase Prime Broker.

Peg Order

This change will be available in Q4 2025 We are introducing PEG (Pegged) orders, which dynamically adjust their price based on market conditions while maintaining execution discretion. PEG orders “peg” their price to a market reference (best bid/offer) with a configurable offset.

REST API Changes

Create Order Endpoint

Path: POST /v1/portfolios/{portfolio_id}/order New request parameters for PEG orders:

type: required - must be "PEG"
time_in_force: required - must be "GOOD_UNTIL_CANCELLED" or "GOOD_UNTIL_DATE_TIME"
limit_price: required - acts as ceiling (BUY) or floor (SELL)
peg_offset_type: required - "PEG_OFFSET_TYPE_PRICE", "PEG_OFFSET_TYPE_BASIS_POINTS", or "PEG_OFFSET_TYPE_CUMULATIVE_DEPTH_IN_BASE_UNITS"
offset: required - offset value (0 means peg to best bid/offer)
wig_level: optional - “Would if Good” level for aggressive fills
expiry_time: optional - required if time_in_force is "GOOD_UNTIL_DATE_TIME"

FIX API Changes

The following fields will be added to New Order Single (D)

Tag	Req	Name	Notes
836	Y	PegOffsetType	0 = Price 1 = Basis Points 4 = Cumulative depth in base units
211	Y	PegOffsetValue	The units in price, basis points, or cumulative depth that offset the peg price.
8007	N	WigLevel	The target price to actively fill the remaining balance of your order

The following field will be added to OrdType Values

Value	Description
P	Adaptive Peg order

The following field will be added to TargetStrategy Values

Value	Description	OrdType	TimeInForce
P	Adaptive Peg order	Must be P (PEGGED)	Must be 1 (GTC) or 6 (GTD)

Get Unstaking Status Endpoint

This change will be available in late October to early November 2025 We are introducing a new endpoint to retrieve the status of ongoing unstaking operations for an Ethereum wallet. Prime Rest API:

Get Unstaking Status: GET /v1/portfolios/{portfolio_id}/wallets/{wallet_id}/staking/unstake/status - retrieve status of all active unstaking requests

This endpoint will allow you to view the current status of unstaking operations in progress, including estimated completion times and amounts for each validator. This feature will initially only support ETH. Request:

{
  "portfolio_id": "string",
  "wallet_id": "string"
}

Response:

{
  "portfolio_id": "string",
  "wallet_id": "string",
  "wallet_address": "string",
  "current_timestamp": "string",
  "validators": [
    {
      "validator_address": "string",
      "statuses": [
        {
          "amount": "string",
          "unstake_type": "UNSTAKE_TYPE_PARTIAL | UNSTAKE_TYPE_FULL",
          "finishing_at": "string",
          "remaining_hours": "string",
          "requested_at": "string",
          "estimate_type": "LIVE | INTERIM",
          "estimate_description": "string"
        }
      ]
    }
  ]
}

Prime Multinetwork Support

We’re expanding network support to make capital movement faster, cheaper, and easier:

ETH on Base and USDC on Base, Solana, Arbitrum, Optimism, and Avalanche C-Chain can now be transferred efficiently and at no cost within your trading balance on the Prime UI.
API support will be available starting November 3rd.

Users will now be able to view and manage assets across multiple networks. We will be updating the use of symbol to represent assets on different blockchains. This will be available to users as “network_scoped_symbol” in the List Entity Assets endpoint for each individual network supported for an asset. Example:

If a user wants to represent USDC on the Base network, they will use the "network_scoped_symbol" BASEUSDC.
When a user calls the ListEntityAssets endpoint for USDC, the response will include a unique “network_scoped_symbol” for USDC on each supported network, such as BASEUSDC for Base, OPTUSDC for Optimism, and so on.

Users can use the “network_scoped_symbol” to get asset details specific to each network. Users can also add a new query parameter to see combined information for an asset across all supported networks denoted as:

“get_network_unified_transactions”
”get_network_unified_wallets”
“get_network_unified_activites”
“unified_total_balances”

All Endpoint Changes:

List Portfolio Transactions
- Users can enter a “network_scoped_symbol” in the ‘symbols’ query parameter to get transactions for an asset on a specific network
- Users can enter optional “get_network_unified_transactions” as a boolean query parameter to get transactions across all networks
List Entity Activities
- Users can enter “network_scoped_symbol” in the ‘symbols’ query parameter to view activities for an asset on a specific network
- Users can enter “get_network_unified_activities” as a boolean query parameter to get activities across all networks
List Portfolio Activities
- Users can enter “network_scoped_symbol” in the ‘symbols’ query parameter to view portfolio activities for an asset on a specific network
- Users can enter “get_network_unified_activities” as a boolean query parameter to get activities across all networks

Network Scoped Symbols:

Asset - Symbol	Network Name	Network_Scoped_Symbol
USDC	Ethereum	usdc
USDC	Avalanche C-Chain	avausdc
USDC	Optimism	optusdc
USDC	Base	baseusdc
USDC	Solana	splusdc
USDC	Arbitrum	arbusdc
ETH	Ethereum	eth
ETH	Base	baseeth

Financing API Enhancements

This change will be published in late October to early November 2025 We are implementing changes to an existing endpoint and adding two new endpoints to enhance the API experience for users of the Trade Finance and Bilateral Lending products.

List TF Obligations Endpoint

      "notional_amount": "23928.87",
      "due_date": "2025-08-13T22:00:00Z"
    }
  ]
}

    {
      "asset": "XYO", 
      "asset_adjustment": "0.4", 
      "liability_adjustment": "3"
    },
    {
      "asset": "XRP", 
      "asset_adjustment": "0.7", 
      "liability_adjustment": "1.5"
    },
    ...
  ]
}

List Interest Accruals Endpoint

This endpoint will now additionally include interest accruals for Bilateral Lending (in addition to Trade Finance and Portfolio Margin, as currently implemented)
