Usage

Use this SDK to programmatically create Ethereum transactions, and submit them to custodians connected with MetaMask Institutional. Automate trading strategies on your wallets under custody, and still benefit from the institutional-grade security of your favorite qualified custodian and custody provider.

Getting started

Setting up

$ pip install metamask-institutional.sdk

>>> from metamask_institutional.sdk import CustodianFactory

>>> factory = CustodianFactory()

>>> custodian = factory.create_for("qredo", "YOUR-TOKEN")

Use the custodian’s Factory name param in the table below to instantiate a client for the right custodian.

Custodian Supported As of version Factory name param
Bitgo ✅ 0.3.0 "bitgo"
Cactus ✅ 0.2.0 "cactus"
FPG ✅ 0.4.0 "fpg-prod"
Gnosis Safe ✅ 0.4.0 "gnosis-safe"
Qredo ✅ 0.2.0 "qredo"
Saturn ✅ 0.4.0 "saturn"

Creating a transaction

import os

from metamask_institutional.sdk import CustodianFactory

# Instantiate the factory
factory = CustodianFactory()

# Grab your token from the environment, or anywhere else
token = os.environ["MMISDK_TOKEN_QREDO"]

# Create the custodian, using the factory
custodian = factory.create_for("qredo", token)

# Build tx details
tx_params = {
    "from": "0x62468FD916bF27A3b76d3de2e5280e53078e13E1",
    "to": "0x62468FD916bF27A3b76d3de2e5280e53078e13E1",
    "value": "100000000000000000",  # in Wei
    "gas": "21000",
    "gasPrice": "1000",
    # "data": "0xsomething",
    # "type": "2"
    # "maxPriorityFeePerGas": "12321321",
    # "maxFeePerGas": "12321321",
}
qredo_extra_params = {
    "chainID": "3",
}

# Create the tx from details and send it to the custodian
transaction = custodian.create_transaction(tx_params, qredo_extra_params)
print(type(transaction))
# <class 'metamask-institutional.sdk.common.transaction.Transaction'>

print(transaction)
# id='2EzDJkLVIjmH6LZQ2W1T4wPcTtK'

Getting a transaction

import os

from metamask_institutional.sdk import CustodianFactory

# Instantiate the factory
factory = CustodianFactory()

# Grab your token from the environment, or anywhere else
token = os.environ["MMISDK_TOKEN_CACTUS"]

# Create the custodian, using the factory
custodian = factory.create_for("cactus", token)

# Get the transaction
transaction = custodian.get_transaction("5CM05NCLMRD888888000800", 5)

print(type(transaction))
# <class 'metamask-institutional.sdk.common.transaction.Transaction'>

print(transaction)
