2 years ago Hello @robtrip. About the 2nd issue. I did the testing on rinkeby env with test account and the following snapshot looks fine:
from decimal import *
from web3 import Web3, HTTPProvider, Account
from zksync_sdk import ZkSyncProviderV01, HttpJsonRPCTransport, network, ZkSync, EthereumProvider, Wallet, ZkSyncSigner, EthereumSignerWeb3, ZkSyncLibrary
import asyncio
from zksync_sdk.types import ChangePubKeyEcdsa
class TestEnv:
PRIVATE_KEY = "_YOUR_PRIVATE_KEY_"
def __init__(self):
self.library = ZkSyncLibrary()
self.provider = ZkSyncProviderV01(provider=HttpJsonRPCTransport(network=network.YOUR_SERVER))
self.account = Account.from_key(self.PRIVATE_KEY)
self.signer = ZkSyncSigner.from_account(self.account, self.library, network.YOUR_SERVER.chain_id)
def main():
# Here could be your value for testing
value = Decimal(1)
env = TestEnv()
async def get_contract_address():
contracts = await env.provider.get_contract_address()
return contracts
loop = asyncio.get_event_loop()
task = loop.create_task(get_contract_address())
loop.run_until_complete(task)
contracts = task.result()
# Setup web3
w3 = Web3(HTTPProvider(endpoint_uri="SERVER_ENDPOINT_URL"))
# Setup zksync contract interactor
zksync = ZkSync(account=env.account, web3=w3,
zksync_contract_address=contracts.main_contract)
# Create ethereum provider for interacting with ethereum node
ethereum_provider = EthereumProvider(w3, zksync)
ethereum_signer = EthereumSignerWeb3(account=env.account)
# Initialize zksync signer, all creating options were described earlier
signer = ZkSyncSigner.from_account(env.account, env.library, network.rinkeby.chain_id)
# Initialize Wallet
wallet = Wallet(ethereum_provider=ethereum_provider, zk_signer=signer,
eth_signer=ethereum_signer, provider=env.provider)
# Find token for depositing
async def resolve_token(wallet, token):
token = await wallet.resolve_token(token)
return token
task = loop.create_task(resolve_token(wallet, "USDT"))
loop.run_until_complete(task)
token = task.result()
print('TOKEN')
print(token)
print('\n')
# Approve Enough deposit using token contract
async def approve_deposit(token, decimal, wallet):
res = await wallet.ethereum_provider.approve_deposit(token, decimal)
return res
task = loop.create_task(approve_deposit(token, value, wallet))
loop.run_until_complete(task)
result = task.result()
print('APPROVE')
print(result)
print('\n')
async def deposit(token, decimal, address, wallet):
res = await wallet.ethereum_provider.deposit(token, decimal, address)
return res
task = loop.create_task(deposit(token, value, env.account.address, wallet))
loop.run_until_complete(task)
result = task.result()
print('DEPOSIT')
print(result)
print('\n')
# Unlocking zkSync account
async def unlock_wallet(wallet):
if not await wallet.is_signing_key_set():
print('NOT SET')
await wallet.set_signing_key("ETH", eth_auth_data=ChangePubKeyEcdsa())
return
task = loop.create_task(unlock_wallet(wallet))
loop.run_until_complete(task)
result = task.result()
print('UNLOCK WALLET')
print(result)
print('\n')
## checking balance
# Committed state is not final yet
async def get_balance(token):
committedBalance = await wallet.get_balance(token, "committed")
return committedBalance
task = loop.create_task(get_balance("USDT"))
loop.run_until_complete(task)
result = task.result()
print(f"USDC balance: {result}")
if __name__ == "__main__":
main()Can you please test it on your side and in the case of fails provide more details like test account settings etc?
About 1st issue described here it needs time for detailed investigation.

Hey team really struggling to get the python sdk working. The snippets are a bit helpful but figuring out the whole async stuff works has been a nightmare, also had some weird issue loading the dylib. If you could just include a fully working code example it would be a lot easier!
Anyways I'm now stuck on 2 points:
1) on calling deposit, I see a transaction go out but no ERC20 tokens leave my wallet which I believe is incorrect? I would have expected to see the USDT leave my wallet with the deposit? https://ropsten.etherscan.io/tx/0x00a13d37504616c4095a88854dff0f812ac73bf101a80c37c0f1bc334e10d796
--> follow up: this seems to be linked to the fact that USDT contract returned by the resolve_token function (0x3b00ef435fa4fcff5c209a37d1f3dcff37c705ad) has been self-destructed. I guess this is because you're all working off of v2 so testnet v1 is basically deprecated? I couldn't see how to manually load a token in from the code.
2) once await wallet.set_signing_key("ETH", eth_auth_data=ChangePubKeyEcdsa()) is hit I get the following error.
Thanks so much in advance
My code below:
