Withdraw transactions in MPC Wallets and Custodial Wallets follow distinct creation processes via APIs.
In MPC Wallets, kindly take note of the distinctions between transactions created on Account-based blockchains and those on UTXO-based blockchains.
The following code samples focus on Account-based blockchains.
For information on how to create a transaction on UTXO-based blockchains, please refer to this guide.
The following codes demonstrate the transfer of 0.1 ETH to a specified receiving address via Account-based blockchains.
from cobo_custody.client.mpc_client import MPCClient
from cobo_custody.config import DEVELOP_ENV
from cobo_custody.signer.local_signer import LocalSigner
import time
api_secret ="your api secret"# your wallet api secret
chain_code ="ETH"# your target chain
coin_code ="ETH"# your target coin
amount ="100000000000000000"# withdraw amount：0.01ETH
from_address ="your mpc wallet address"# your mpc wallet address
to_address ="your address"# your address# init cobo client
mpc_client = MPCClient(signer=LocalSigner(api_secret), env=DEVELOP_ENV, debug=False)
request_id =f"MPCTransaction-{int(time.time()*1000)}"# your custom request_id
response = mpc_client.create_transaction(
coin=coin_code,
request_id=request_id,
amount=amount,
from_addr=from_address,
to_addr=to_address,
gas_price=6500000000,
gas_limit=21000,)print(f"Withdraw: {response.result}")

In Custodial Wallets, an on-chain transaction will be triggered if the receiving address is an external address.
Conversely, if the receiving address belongs to a Custodial Wallet managed by Cobo,
the transaction will be executed off-chain without incurring any gas fees.
