v2-action-signing-python

Python package to sign the following on-chain self-custodial requests:

1. order
2. RFQ quote
3. RFQ execution
4. transfer positions

Although the below actions are supported by the SDK, we recommend you use the UX developer portal (https://docs.derive.xyz/docs/onboard-via-interface):

4. create subaccount
5. deposit
6. withdrawal
7. transfer collateral

Usage

1. Install package: pip install lyra_v2_action_signing

2. Sign an order

from web3 import Web3
from lyra_v2_action_signing import SignedAction, TradeModuleData, utils

session_key_wallet = Web3().eth.account.from_key("0x2ae8be44db8a590d20bffbe3b6872df9b569147d3bf6801a35a28281a4816bbd")

action = SignedAction(
    subaccount_id=30769,
    owner=SMART_CONTRACT_WALLET_ADDRESS, # from Protocol Constants table in docs.lyra.finance
    signer=session_key_wallet.address,
    signature_expiry_sec=utils.MAX_INT_32,
    nonce=utils.get_action_nonce(),
    module_address=TRADE_MODULE_ADDRESS, # from Protocol Constants table in docs.lyra.finance
    module_data=TradeModuleData(
        asset=instrument_ticker["base_asset_address"],
        sub_id=int(instrument_ticker["base_asset_sub_id"]),
        limit_price=Decimal("100"),
        amount=Decimal("1"),
        max_fee=Decimal("1000"),
        recipient_id=30769,
        is_bid=True,
    ),
    DOMAIN_SEPARATOR=DOMAIN_SEPARATOR, # from Protocol Constants table in docs.derive.xyz
    ACTION_TYPEHASH=ACTION_TYPEHASH, # from Protocol Constants table in docs.derive.xyz
)

action.sign(session_key_wallet.key)
