CDP SDK

This module contains the Python CDP SDK, which is a library that provides a client for interacting with the Coinbase Developer Platform (CDP). It includes a CDP Client for interacting with EVM and Solana APIs to create accounts and send transactions, policy APIs to govern transaction permissions, as well as authentication tools for interacting directly with the CDP APIs.

Documentation

CDP SDK has auto-generated docs for the Python SDK.

Further documentation is also available on the CDP docs website:

Installation

pip install cdp-sdk

API Keys

To start, create a CDP API Key. Save the API Key ID and API Key Secret for use in the SDK. You will also need to create a wallet secret in the Portal to sign transactions.

Usage

Initialization

Load client config from shell

One option is to export your CDP API Key and Wallet Secret as environment variables:

export CDP_API_KEY_ID="YOUR_API_KEY_ID"
export CDP_API_KEY_SECRET="YOUR_API_KEY_SECRET"
export CDP_WALLET_SECRET="YOUR_WALLET_SECRET"

Then, initialize the client:

from cdp import CdpClient
import asyncio

async def main():
    async with CdpClient() as cdp:
        pass

asyncio.run(main())
Load client config from .env file

Another option is to save your CDP API Key and Wallet Secret in a .env file:

touch .env
echo "CDP_API_KEY_ID=YOUR_API_KEY_ID" >> .env
echo "CDP_API_KEY_SECRET=YOUR_API_KEY_SECRET" >> .env
echo "CDP_WALLET_SECRET=YOUR_WALLET_SECRET" >> .env

Then, load the client config from the .env file:

from cdp import CdpClient
from dotenv import load_dotenv
import asyncio

load_dotenv()

async def main():
    async with CdpClient() as cdp:
        pass

asyncio.run(main())
Pass the API Key and Wallet Secret to the client

Another option is to directly pass the API Key and Wallet Secret to the client:

import asyncio
from cdp import CdpClient

async def main():
    async with CdpClient(
        api_key_id="YOUR_API_KEY_ID",
        api_key_secret="YOUR_API_KEY_SECRET",
        wallet_secret="YOUR_WALLET_SECRET",
    ) as cdp:
        pass

asyncio.run(main())

Creating EVM or Solana accounts

Create an EVM account as follows:

private_key = await cdp.solana.export_account(
  name="MyAccount",
)

# by address
private_key = await cdp.solana.export_account(
  address="Abc",
)
Get or create an EVM account as follows:
import asyncio
from cdp import CdpClient

        account = await cdp.evm.get_or_create_smart_account(name="Account1", owner=owner)

asyncio.run(main())

Creating EVM or Solana accounts with policies

Create an EVM account with policy as follows:
account = await cdp.evm.create_account(
    name="AccountWithPolicy",
    account_policy="abcdef12-3456-7890-1234-567890123456",
)
Create a Solana account with policy as follows:
account = await cdp.solana.create_account(
    name="AccountWithPolicy",
    account_policy="abcdef12-3456-7890-1234-567890123456",
)

Updating EVM or Solana accounts

  address=account.address,
  update=UpdateAccountOptions(
    name="Updated name",
    account_policy="1622d4b7-9d60-44a2-9a6a-e9bbb167e412",
  ),
)

        await cdp.solana.request_faucet(
            address=address, token="sol"
        )

asyncio.run(main())

Sending transactions

EVM

You can use CDP SDK to send transactions on EVM networks. By default, Coinbase will manage the nonce and gas for you.

import asyncio

from dotenv import load_dotenv
from web3 import Web3

from cdp import CdpClient
from cdp.evm_transaction_types import TransactionRequestEIP1559

w3 = Web3(Web3.HTTPProvider("https://sepolia.base.org"))


async def main():
    load_dotenv()

    async with CdpClient() as cdp:
        evm_account = await cdp.evm.create_account()

        faucet_hash = await cdp.evm.request_faucet(
            address=evm_account.address, network="base-sepolia", token="eth"
        )

        w3.eth.wait_for_transaction_receipt(faucet_hash)

        zero_address = "0x0000000000000000000000000000000000000000"

        amount_to_send = w3.to_wei(0.000001, "ether")

        tx_hash = await cdp.evm.send_transaction(
            address=evm_account.address,
            transaction=TransactionRequestEIP1559(
                to=zero_address,
                value=amount_to_send,
            ),
            network="base-sepolia",
        )

        print(f"Transaction sent! Hash: {tx_hash}")

        print("Waiting for transaction confirmation...")
        tx_receipt = w3.eth.wait_for_transaction_receipt(tx_hash)
        print(f"Transaction confirmed in block {tx_receipt.blockNumber}")
        print(f"Transaction status: {'Success' if tx_receipt.status == 1 else 'Failed'}")


asyncio.run(main())

If you’d like to manage the nonce and gas yourself, you can do so as follows:

import asyncio

from dotenv import load_dotenv
from web3 import Web3

from cdp import CdpClient
from cdp.evm_transaction_types import TransactionRequestEIP1559

w3 = Web3(Web3.HTTPProvider("https://sepolia.base.org"))


async def main():
    load_dotenv()

    async with CdpClient() as cdp:
        evm_account = await cdp.evm.create_account()

        faucet_hash = await cdp.evm.request_faucet(
            address=evm_account.address, network="base-sepolia", token="eth"
        )

        w3.eth.wait_for_transaction_receipt(faucet_hash)

        zero_address = "0x0000000000000000000000000000000000000000"

        amount_to_send = w3.to_wei(0.000001, "ether")

        nonce = w3.eth.get_transaction_count(evm_account.address)

        gas_estimate = w3.eth.estimate_gas(
            {"to": zero_address, "from": evm_account.address, "value": amount_to_send}
        )

        max_priority_fee = w3.eth.max_priority_fee
        max_fee = w3.eth.gas_price + max_priority_fee

        tx_hash = await cdp.evm.send_transaction(
            address=evm_account.address,
            transaction=TransactionRequestEIP1559(
                to=zero_address,
                value=amount_to_send,
                gas=gas_estimate,
                maxFeePerGas=max_fee,
                maxPriorityFeePerGas=max_priority_fee,
                nonce=nonce,
            ),
            network="base-sepolia",
        )

        print(f"Transaction sent! Hash: {tx_hash}")

        print("Waiting for transaction confirmation...")
        tx_receipt = w3.eth.wait_for_transaction_receipt(tx_hash)
        print(f"Transaction confirmed in block {tx_receipt.blockNumber}")
        print(f"Transaction status: {'Success' if tx_receipt.status == 1 else 'Failed'}")


asyncio.run(main())

You can also use DynamicFeeTransaction from eth-account:

import asyncio

from dotenv import load_dotenv
from web3 import Web3

from cdp import CdpClient
from eth_account.typed_transactions import DynamicFeeTransaction

w3 = Web3(Web3.HTTPProvider("https://sepolia.base.org"))


async def main():
    load_dotenv()

    async with CdpClient() as cdp:
        evm_account = await cdp.evm.create_account()

        faucet_hash = await cdp.evm.request_faucet(
            address=evm_account.address, network="base-sepolia", token="eth"
        )

        w3.eth.wait_for_transaction_receipt(faucet_hash)

        zero_address = "0x0000000000000000000000000000000000000000"

        amount_to_send = w3.to_wei(0.000001, "ether")

        nonce = w3.eth.get_transaction_count(evm_account.address)

        gas_estimate = w3.eth.estimate_gas(
            {"to": zero_address, "from": evm_account.address, "value": amount_to_send}
        )

        max_priority_fee = w3.eth.max_priority_fee
        max_fee = w3.eth.gas_price + max_priority_fee

        tx_hash = await cdp.evm.send_transaction(
            address=evm_account.address,
            transaction=DynamicFeeTransaction.from_dict(
                {
                "to": zero_address,
                "value": amount_to_send,
                "chainId": 84532,
                "gas": gas_estimate,
                "maxFeePerGas": max_fee,
                "maxPriorityFeePerGas": max_priority_fee,
                "nonce": nonce,
                "type": "0x2",
                }
            ),
            network="base-sepolia",
        )

        print(f"Transaction sent! Hash: {tx_hash}")

        print("Waiting for transaction confirmation...")
        tx_receipt = w3.eth.wait_for_transaction_receipt(tx_hash)
        print(f"Transaction confirmed in block {tx_receipt.blockNumber}")
        print(f"Transaction status: {'Success' if tx_receipt.status == 1 else 'Failed'}")


asyncio.run(main())

CDP SDK server accounts are compatible with eth-account’s BaseAccount interface via EvmLocalAccount. With it, you may sign a hash, message, typed data, or a transaction.

import asyncio

from cdp import CdpClient
from dotenv import load_dotenv
from cdp.evm_local_account import EvmLocalAccount
from web3 import Web3

load_dotenv()


async def main():
    async with CdpClient() as cdp:
        account = await cdp.evm.get_or_create_account(name="MyServerAccount")
        evm_local_account = EvmLocalAccount(account)

        # Sign a transaction.
        w3 = Web3(Web3.HTTPProvider("https://sepolia.base.org"))
        nonce = w3.eth.get_transaction_count(evm_local_account.address)
        transaction = evm_local_account.sign_transaction(
            transaction_dict={
                "to": "0x000000000000000000000000000000000000dEaD",
                "value": 10000000000,
                "chainId": 84532,
                "gas": 21000,
                "maxFeePerGas": 1000000000,
                "maxPriorityFeePerGas": 1000000000,
                "nonce": nonce,
                "type": "0x2",
            }
        )

        faucet_hash = await cdp.evm.request_faucet(
            address=evm_local_account.address, network="base-sepolia", token="eth"
        )
        w3.eth.wait_for_transaction_receipt(faucet_hash)

        # Use Web3 to send the transaction.
        tx_hash = w3.eth.send_raw_transaction(transaction.raw_transaction)
        tx_receipt = w3.eth.wait_for_transaction_receipt(tx_hash)
        print(f"Transaction receipt: {tx_receipt}")


asyncio.run(main())
Solana

For Solana, we recommend using the solana library to send transactions. See the examples.

Transferring tokens

EVM

For complete examples, check out account.transfer.py and smart_account.transfer.py.

You can transfer tokens between accounts using the transfer function:

sender = await cdp.evm.create_account(name="Sender")

tx_hash = await sender.transfer(
    to="0x9F663335Cd6Ad02a37B633602E98866CF944124d",
    amount=w3.to_wei("0.001", "ether"),
    token="eth",
    network="base-sepolia",
)

w3.eth.wait_for_transaction_receipt(tx_hash)

To send USDC, the SDK exports a helper function to convert a whole number to a bigint:

from cdp import parse_units

# returns atomic representation of 0.01 USDC, which uses 6 decimal places
amount = parse_units("0.01", 6)

tx_hash = await sender.transfer(
    to="0x9F663335Cd6Ad02a37B633602E98866CF944124d",
    amount=amount,
    token="usdc",
    network="base-sepolia",
)

Smart Accounts also have a transfer function:

from cdp import parse_units

sender = await cdp.evm.create_smart_account(
    owner=privateKeyToAccount(generatePrivateKey()),
);
print("Created smart account", sender);

transfer_result = await sender.transfer(
    to="0x9F663335Cd6Ad02a37B633602E98866CF944124d",
    amount=parse_units("0.01", 6),
    token="usdc",
    network="base-sepolia",
)

user_op_result = await sender.wait_for_user_operation(user_op_hash=transfer_result.user_op_hash)

Using Smart Accounts, you can also specify a paymaster URL:

transfer_result = await sender.transfer(
    to="0x9F663335Cd6Ad02a37B633602E98866CF944124d",
    amount="0.01",
    token="usdc",
    network="base-sepolia",
    paymaster_url="https://some-paymaster-url.com",
)

You can pass usdc or eth as the token to transfer, or you can pass a contract address directly:

transfer_result = await sender.transfer(
    to="0x9F663335Cd6Ad02a37B633602E98866CF944124d",
    amount=w3.to_wei("0.000001", "ether"),
    token="0x4200000000000000000000000000000000000006", # WETH on Base Sepolia
    network="base-sepolia",
)

You can pass another account as the to parameter:

from cdp import parse_units

sender = await cdp.evm.create_account(name="Sender")
receiver = await cdp.evm.create_account(name="Receiver")

transfer_result = await sender.transfer(
    to=receiver,
    amount=parse_units("0.01", 6),
    token="usdc",
    network="base-sepolia",
)
Solana

For complete examples, check out solana/account.transfer.py.

You can transfer tokens between accounts using the transfer function, and wait for the transaction to be confirmed using the confirmTransaction function from solana:

import asyncio
from cdp import CdpClient
from solana.rpc.api import Client as SolanaClient

async def main():
    async with CdpClient() as cdp:
        sender = await cdp.solana.create_account()

        connection = SolanaClient("https://api.devnet.solana.com")

        signature = await sender.transfer({
            to="3KzDtddx4i53FBkvCzuDmRbaMozTZoJBb1TToWhz3JfE",
            amount=0.01 * LAMPORTS_PER_SOL,
            token="sol",
            network=connection,
        });

        blockhash, lastValidBlockHeight = await connection.get_latest_blockhash()

        confirmation = await connection.confirm_transaction(
            {
                signature,
                blockhash,
                lastValidBlockHeight,
            },
        )

        if confirmation.value.err:
            print(f"Something went wrong! Error: {confirmation.value.err.toString()}")
        else:
            print(
                f"Transaction confirmed: Link: https://explorer.solana.com/tx/${signature}?cluster=devnet",
            )

To send USDC, the SDK exports a helper function to convert a whole number to a bigint:

from cdp import parse_units

# returns atomic representation of 0.01 USDC, which uses 6 decimal places
amount = parse_units("0.01", 6)

tx_hash = await sender.transfer(
    to="0x9F663335Cd6Ad02a37B633602E98866CF944124d",
    amount=amount,
    token="usdc",
    network="devet",
)

EVM Swaps

You can use the CDP SDK to swap tokens on EVM networks using both regular accounts (EOAs) and smart accounts.

The SDK provides three approaches for performing token swaps:

2. Get pricing information

Use get_swap_price for quick price estimates and display purposes. This is ideal for showing exchange rates without committing to a swap:

# Get price for swapping 1 WETH to USDC
price = await cdp.evm.get_swap_price(
    from_token="0x4200000000000000000000000000000000000006",  # WETH
    to_token="0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913",  # USDC
    from_amount="1000000000000000000",  # 1 WETH (18 decimals)
    network="base",
    taker="0x1234567890123456789012345678901234567890"
)

if price.liquidity_available:
    print(f"You'll receive: {price.to_amount} USDC")
    print(f"Minimum after slippage: {price.min_to_amount} USDC")

Note: get_swap_price does not reserve funds or signal commitment to swap, making it suitable for more frequent price updates with less strict rate limiting - although the data may be slightly less precise.

3. Create and execute separately

Use account.quote_swap() / smart_account.quote_swap() when you need full control over the swap process. This returns complete transaction data for execution:

Important: quote_swap() signals a soft commitment to swap and may reserve funds on-chain. It is rate-limited more strictly than get_swap_price to prevent abuse.

Regular Account (EOA):



# Retrieve an existing EVM account with funds already in it
account = await cdp.evm.get_or_create_account(name="MyExistingFundedAccount")

# Step 1: Create a swap quote with full transaction details
swap_quote = await account.quote_swap(
    from_token="0x4200000000000000000000000000000000000006",  # WETH
    to_token="0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913",  # USDC
    from_amount="1000000000000000000",  # 1 WETH (18 decimals)
    network="base",
    slippage_bps=100  # 1% slippage tolerance
)

# Step 2: Check if liquidity is available, and/or perform other analysis on the swap quote
if not swap_quote.liquidity_available:
    print("Insufficient liquidity for swap")
else:
    # Step 3: Execute using the quote
    result = await swap_quote.execute()
    print(f"Transaction hash: {result.transaction_hash}")

Smart Account:

# Create or retrieve a smart account with funds already in it
owner = await cdp.evm.get_or_create_account(name="MyOwnerAccount")
smart_account = await cdp.evm.get_or_create_smart_account(name="MyExistingFundedSmartAccount", owner=owner)

# Step 1: Create a swap quote with full transaction details for smart account
swap_quote = await smart_account.quote_swap(
    from_token="0x4200000000000000000000000000000000000006",  # WETH
    to_token="0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913",  # USDC
    from_amount="1000000000000000000",  # 1 WETH (18 decimals)
    network="base",
    slippage_bps=100,  # 1% slippage tolerance
    # Optional: paymaster_url="https://paymaster.example.com"  # For gas sponsorship
)

# Step 2: Check if liquidity is available, and/or perform other analysis on the swap quote
if not swap_quote.liquidity_available:
    print("Insufficient liquidity for swap")
else:
    # Step 3: Execute using the quote
    result = await swap_quote.execute()
    print(f"User operation hash: {result.user_op_hash}")

    # Wait for the user operation to complete
    receipt = await smart_account.wait_for_user_operation(user_op_hash=result.user_op_hash)
    print(f"Status: {receipt.status}")
When to use each approach:

  • All-in-one (account.swap() / smart_account.swap()): Best for most use cases. Simple, handles everything automatically.

  • Price only (get_swap_price): For displaying exchange rates, building price calculators, or checking liquidity without executing. Suitable when frequent price updates are needed - although the data may be slightly less precise.

  • Create then execute (account.quote_swap() / smart_account.quote_swap()): When you need to inspect swap details, implement custom logic, or handle complex scenarios before execution. Note: May reserve funds on-chain and is more strictly rate-limited.

Key differences between Regular Accounts (EOAs) and Smart Accounts:

  • Regular accounts (EOAs) return transaction_hash and execute immediately on-chain

  • Smart accounts return user_op_hash and execute via user operations with optional gas sponsorship through paymasters

  • Smart accounts require an owner account for signing operations

  • Smart accounts support batch operations and advanced account abstraction features

All approaches handle Permit2 signatures automatically for ERC20 token swaps. Make sure tokens have proper allowances set for the Permit2 contract before swapping.

Example implementations

To help you get started with token swaps in your application, we provide the following fully-working examples demonstrating different scenarios:

EVM Smart Accounts

For EVM, we support Smart Accounts which are account-abstraction (ERC-4337) accounts. Currently there is only support for Base Sepolia and Base Mainnet for Smart Accounts.

Create an EVM account and a smart account as follows:
import asyncio
from cdp import CdpClient

async def main():
    async with CdpClient() as cdp:
        evm_account = await cdp.evm.create_account()
        smart_account = await cdp.evm.create_smart_account(
            owner=evm_account
        )

asyncio.run(main())
Sending User Operations
import asyncio
from cdp.evm_call_types import EncodedCall
from cdp import CdpClient

async def main():
    async with CdpClient() as cdp:
        user_operation = await cdp.evm.send_user_operation(
            smart_account=smart_account,
            network="base-sepolia",
            calls=[
                EncodedCall(
                    to="0x0000000000000000000000000000000000000000",
                    value=0,
                    data="0x"
                )
            ]
        )

asyncio.run(main())
In Base Sepolia, all user operations are gasless by default. If you’d like to specify a different paymaster, you can do so as follows:
import asyncio
from cdp.evm_call_types import EncodedCall
from cdp import CdpClient

async def main():
    async with CdpClient() as cdp:
        user_operation = await cdp.evm.send_user_operation(
            smart_account=smart_account,
            network="base-sepolia",
            calls=[],
            paymaster_url="https://some-paymaster-url.com"
        )

asyncio.run(main())

Account Actions

Account objects have actions that can be used to interact with the account. These can be used in place of the cdp client.

For example, instead of:

token_balances = await cdp.evm.list_token_balances(
    address=account.address,
    network="base-sepolia"
)

You can use the list_token_balances action:

balances = await account.list_token_balances(
    network="base-sepolia",
)

EvmAccount supports the following actions:

  • list_token_balances

  • request_faucet

  • sign_transaction

  • send_transaction

  • transfer

  • swap

  • quote_swap

EvmSmartAccount supports the following actions:

  • list_token_balances

  • request_faucet

  • send_user_operation

  • wait_for_user_operation

  • get_user_operation

  • transfer

  • swap

  • quote_swap

SolanaAccount supports the following actions:

  • sign_message

  • sign_transaction

  • request_faucet

Policy Management

You can use the policies SDK to manage sets of rules that govern the behavior of accounts and projects, such as enforce allowlists and denylists.

Create a Project-level policy that applies to all accounts

This policy will accept any account sending less than a specific amount of ETH to a specific address.

policy = await cdp.policies.create_policy(
    policy=CreatePolicyOptions(
        scope="project",
        description="Project-wide Allowlist Example",
        rules=[
            SignEvmTransactionRule(
                action="accept",
                criteria=[
                    EthValueCriterion(
                        ethValue="1000000000000000000",
                        operator="<=",
                    ),
                    EvmAddressCriterion(
                        addresses=["0x000000000000000000000000000000000000dEaD"],
                        operator="in",
                    ),
                ],
            ),
        ],
    )
)

Create an Account-level policy

This policy will accept any transaction with a value less than or equal to 1 ETH to a specific address.

policy = await cdp.policies.create_policy(
    policy=CreatePolicyOptions(
        scope="account",
        description="Account Allowlist Example",
        rules=[
            SignEvmTransactionRule(
                action="accept",
                criteria=[
                    EthValueCriterion(
                        ethValue="1000000000000000000",
                        operator="<=",
                    ),
                    EvmAddressCriterion(
                        addresses=["0x000000000000000000000000000000000000dEaD"],
                        operator="in",
                    ),
                ],
            ),
        ],
    )
)

Create a Solana Allowlist Policy

policy = await cdp.policies.create_policy(
    policy=CreatePolicyOptions(
        scope="account",
        description="Account Allowlist Example",
        rules=[
            SignSolanaTransactionRule(
                action="accept",
                criteria=[
                    SolanaAddressCriterion(
                        addresses=["123456789abcdef123456789abcdef12"],
                        operator="in",
                    ),
                ],
            )
        ],
    )
)

List Policies

You can filter by account:

policies = await cdp.policies.list_policies(scope="account")

You can also filter by project:

policies = await cdp.policies.list_policies(scope="project")

Or you can list all of them without any filter:

policies = await cdp.policies.list_policies()

Retrieve a Policy

policies = await cdp.policies.get_policy_by_id(id="__POLICY_ID__")

Update a Policy

This policy will update an existing policy to accept transactions to any address except one.

policy = await cdp.policies.update_policy(
    id="__POLICY_ID__",
    policy=UpdatePolicyOptions(
        description="Updated Denylist Policy",
        rules=[
            SignEvmTransactionRule(
                action="accept",
                criteria=[
                    EvmAddressCriterion(
                        addresses=["0x000000000000000000000000000000000000dEaD"],
                        operator="not in",
                    ),
                ],
            )
        ],
    )
)

Delete a Policy

[!WARNING] Attempting to delete an account-level policy in-use by at least one account will fail.

policy = await cdp.policies.delete_policy(id="__POLICY_ID__")
