Coinbase Prime supports receiving funds from external blockchain addresses as well as from other Coinbase wallets (e.g., Prime, Exchange, Coinbase.com), provided the asset is supported on Prime.

​
Retrieving the default deposit address

To deposit funds into Coinbase Prime, a deposit address is required. Request one by calling Get Wallet Deposit Instructions with a relevant Wallet ID. This endpoint will always return the same address for a given wallet—it does not generate a new address for each request. The supported network will also be included in the response. Please review the Wallets page before proceeding. 
WalletsService walletsService = PrimeServiceFactory.createWalletsService(client);

GetWalletDepositInstructionsRequest request = new GetWalletDepositInstructionsRequest.Builder()
    .portfolioId("PORTFOLIO_ID_HERE")
    .walletId("WALLET_ID_HERE")
    .depositType(DepositType.CRYPTO)
    .build();

GetWalletDepositInstructionsResponse response = walletsService.getWalletDepositInstructions(request);

​
Creating unique deposit addresses

Prime also supports generating unique deposit addresses to differentiate between deposits into the same trading balance. This capability allows you to assign individual addresses for enhanced tracking and reconciliation purposes. This feature is particularly valuable for Crypto-as-a-Service (CaaS) clients and other use cases where distinguishing deposit sources is important. While the static deposit address approach is sufficient for most institutional trading scenarios, unique addresses provide additional tracking capabilities when needed. Important: Using unique deposit addresses for end user deposits typically requires enhanced due diligence during onboarding and KYC refresh processes. Please consult with your Coinbase Prime representative to ensure proper compliance procedures are in place. Use Create Wallet Deposit Address to generate a new deposit address for a specific wallet and network. Unlike the static deposit instructions above, this endpoint generates a unique address for each request. 
from prime_sdk.credentials import Credentials
from prime_sdk.client import Client
from prime_sdk.services.wallets import WalletsService, CreateWalletDepositAddressRequest

credentials = Credentials.from_env("PRIME_CREDENTIALS")
client = Client(credentials)
wallets_service = WalletsService(client)

request = CreateWalletDepositAddressRequest(
    portfolio_id="PORTFOLIO_ID_HERE",
    wallet_id="WALLET_ID_HERE",
    network_id="ethereum-mainnet"
)

response = wallets_service.create_wallet_deposit_address(request)

Listing wallet addresses

You can retrieve all previously generated addresses for a wallet using List Wallet Addresses. This is useful for auditing and tracking purposes. 
from prime_sdk.credentials import Credentials
from prime_sdk.client import Client
from prime_sdk.services.wallets import WalletsService, ListWalletAddressesRequest

credentials = Credentials.from_env("PRIME_CREDENTIALS")
client = Client(credentials)
wallets_service = WalletsService(client)

request = ListWalletAddressesRequest(
    portfolio_id="PORTFOLIO_ID_HERE",
    wallet_id="WALLET_ID_HERE",
    network_id="ethereum-mainnet"
)

response = wallets_service.list_wallet_addresses(request)

​
Tracking a deposit

Once a deposit is initiated (e.g., from an external wallet into a Prime wallet), its receipt can be tracked by polling the List Transactions endpoint. Filter by the DEPOSIT transaction type to isolate deposit records. After a deposit is visible here, confirm its availability by checking current balances (using either portfolio- or wallet-level balance endpoints). In general, digital asset deposits to Prime are credited once the relevant network confirmations have been met. For most assets, deposits become available for trading in a matter of seconds or minutes, but this timing may vary based on network conditions. 
TransactionsService transactionsService = PrimeServiceFactory.createTransactionsService(client);

ListPortfolioTransactionsRequest request = new ListPortfolioTransactionsRequest.Builder()
.portfolioId("PORTFOLIO_ID_HERE")
.types("DEPOSIT")
.build();

ListPortfolioTransactionsResponse response = transactionsService.listPortfolioTransactions(request);

​
Deposit Address Reconciliation

All deposit transactions include the specific deposit address that received the funds. Use this address to associate the deposit back to the addresses you generated and assigned to your users, payment invoices, or other tracking purposes. In the transaction response, the transfer_to object contains the exact deposit address as address. The account_identifier field will contain memo or destination tags for blockchain networks that require additional identifiers: 
{
  "transfer_to": {
    "type": "WALLET",
    "value": "0b335245-4f8c-40f4-aed7-64301fdf741c",
    "address": "0x1234567890abcdef1234567890abcdef12345678",
    "account_identifier": ""
  }
}
