flexvaults-sdk 0.1.13

Python SDK for Flexvaults - manage deposits, withdrawals, locks, and transfers

flexvaults-sdk

Python SDK for Flexvaults - manage deposits, withdrawals, locks, and transfers on the accounting module.

Installation

pip install flexvaults-sdk

Quick Start

import asyncio
from flexvaults import FlexvaultsClient, DepositQuoteRequest

async def main():
    async with FlexvaultsClient(base_url="https://api.example.com") as client:
        # Get a deposit quote
        quote = await client.get_deposit_quote(
            DepositQuoteRequest(
                user_address="0xYourAddress",
                token_id="0xTokenId",
                amount=1000000,
            )
        )
        print(f"Deposit to: {quote.deposit_address}")

asyncio.run(main())

Direct SIWE Private Reads

Private read endpoints such as balances and locked funds use the backend's direct SIWE flow. The Python SDK exposes the raw helpers and token setters rather than a hosted auth-code wrapper.

import asyncio
from flexvaults import FlexvaultsClient

async def main():
    async with FlexvaultsClient(base_url="https://api.example.com") as client:
        domain = await client.get_siwe_domain()
        nonce = await client.get_siwe_nonce("0xYourAddress")

        # Build and sign the SIWE message in your app, then submit it here.
        login = await client.authenticate_private_reads(
            siwe_message="your signed-in message",
            signature="0xYourSignature",
        )

        balance = await client.get_balance("0xTokenId")
        print(domain.domain, nonce.nonce, login.address, balance.balance)

asyncio.run(main())

EIP-712 Signing

from eth_account import Account
from flexvaults import (
    sign_lock_message,
    LockNonceResponse,
    SignLockParams,
    LockMessage,
    get_accounting_contract,
    create_lock_expiry,
)

account = Account.from_key("0xYourPrivateKey")

signature = sign_lock_message(
    SignLockParams(
        account=account,
        network="testnet",
        verifying_contract=get_accounting_contract("testnet"),
        message=LockMessage(
            user_address=account.address,
            service_address="0xServiceAddress",
            token_id="0xTokenId",
            amount=1000000,
            expiry=create_lock_expiry(60),
            nonce=0,
        ),
    )
)
