Package: lighter-v2-python
LighterPython client for Lighter (v2). The sdk is tested against Python versions 3.9, 3.10 and 3.11.Installationpipinstalllighter-v2-pythonGetting StartedTheClientobject has four main modules;Api: allows interaction with the lighter apiAsyncApi: allows for async interaction with the lighter apiBlockchain: allows interaction with lighter contractsAsyncBlockchain: allows async interaction with lighter contractsClientcan be created with private key or not depending on whether you are going to use the api or interact with the contracts. For more complete examples, see theexamplesdirectory.APIFollowing parameters are required to useApimodule:api_auth: You should get the key from our servers.web3_provider_url: You need a node to interact with the contract.

The number of operations is limited to 4 million gas. So the limits are roughly;25 order creations in one transaction100 order cancellations in one transaction25 order updates in one transactionfromlighter.lighter_clientimportClientimportosfromlighter.modules.blockchainimportOrderSidefromlighter.constantsimportORDERBOOK_WETH_USDCprivate_key=os.environ.get("SOURCE_PRIVATE_KEY")api_auth=os.environ.get("API_AUTH")client=Client(private_key=private_key,api_auth=api_auth,web3_provider_url="ALCHEMY_URL")x=client.blockchain# initialize the blockchain module before using it# You need to give allowance for the trading tokensclient.blockchain.set_token_max_allowance(spender=client.blockchain.router_contract.address,token="WETH")client.blockchain.set_token_max_allowance(spender=client.blockchain.router_contract.address,token="USDC")# Let's create a batch of limit orderssizes=["0.001","0.001","0.001"]prices=["1050","1200","1000"]sides=[OrderSide.BUY,OrderSide.SELL,OrderSide.BUY]tx_hash=client.blockchain.create_limit_order_batch("WETH_USDC",sizes,prices,sides)# if you want to wait for the transaction to be mined and get order id and other details,# you can use the following method.# alternatively you can wait the data from websocketresult=client.blockchain.get_create_order_transaction_result(tx_hash,"WETH_USDC")Async Examplesfromlighter.lighter_clientimportClientimportosfromlighter.modules.blockchainimportOrderSidefromlighter.constantsimportORDERBOOK_WETH_USDCprivate_key=os.environ.get("SOURCE_PRIVATE_KEY")api_auth=os.environ.get("API_AUTH")client=Client(private_key=private_key,api_auth=api_auth,web3_provider_url="ALCHEMY_URL")asyncdefmain():client.async_blockchain# to initialize the modulesizes=["0.0001"]prices=["1000"]sides=[OrderSide.SELL]# Test async apiprint(awaitclient.async_api.get_blockchains())print(awaitclient.async_api.get_orderbook("WETH_USDC"))print(client.api.get_candles(orderbook_symbol="WETH_USDC",resolution=60,timestamp_start=int(time.time())-60*60*60*24,timestamp_end=int(time.time()),))tx_hash=awaitclient.async_blockchain.create_limit_order_batch("WETH_USDC",sizes,prices,sides)# tx_hash = await client.async_blockchain.cancel_limit_order_batch(#     "WETH_USDC", [24989]# )# tx_hash = await client.async_blockchain.update_limit_order_batch(#     "WETH_USDC", [24991], ["0.0001"], ["100"], [OrderSide.BUY]# )# tx_hash = await client.async_blockchain.create_market_order(#     "WETH_USDC", "0.0001", "100", OrderSide.SELL# )result=awaitclient.async_blockchain.get_create_order_transaction_result(tx_hash,"WETH_USDC")# result = await client.async_blockchain.get_limit_order_canceled_transaction_result(#     tx_hash, "WETH_USDC"# )# result = await client.async_blockchain.get_update_limit_order_transaction_result(#     tx_hash, "WETH_USDC"# )print(result)# close the aiohtpp sessionawaitclient.async_api.close_connection()if__name__=="__main__":importasyncioloop=asyncio.get_event_loop()loop.run_until_complete(main())
