QUESTION
I had do some transaction in Binance Smart Chain in Binance-Peg BUSD-T and it worked successfully. But after 5 transactions. I face to a problem that said Returned error: transaction underpriced
! This is my code:
ANSWER
Answered 2021-Jun-14 at 16:32The "transaction underpriced" error occurs, when you're trying to replace a transaction and the replacing gas price is too low.
web3.eth.getTransactionCount()
only returns the amount of mined transactions. But you can have N (not just one) of transactions that are waiting to be mined with already higher nonce.
Example:
- You have submitted 4 transactions - nonces 1, 2, 3, and 4.
- Transactions 1 and 2 are successfully mined.
getTransactionCount()
returns 2- When you're trying to submit another tx with nonce 3 or 4, it's trying to replace the already existing transactions.
Solution:
Use even higher gas price if you want to replace the existing transaction.
Or if you want to submit a new transaction (and not replace the previous), use higher nonce (sum of "successfully mined" + "waiting to be mined" + 1) that your address haven't used.
QUESTION
I am calling the Binance Klines API to get current prices.
...ANSWER
Answered 2021-Jun-14 at 10:59You're asking for all the symbols (exchangeInfo
) and then getting the candle info (klines
) for each symbol (= currency pair).
You can do so just for the GBP pairs by looking for GBP in the two currencies you're currently iterating on, by adding this to your foreach:
QUESTION
Hi I'm just confused that how to transact BEP-20 Token(e.g: Binance-Peg BUSD-T). I have simply transact bnb in Binance Smart Chain with this code:
...ANSWER
Answered 2021-Jun-14 at 08:58In order to use the .send({from: ...})
method, you need to
Have the
from
account unlocked on your provider.OR
Add its private key to the web3 account wallet (docs)
Ulocked provider account
This approach is mostly used on local providers (e.g. Ganache) that fund and unlock some accounts by default.
Keeping an unlocked account on a production provider is unwise, because anyone who queries the provider can send transactions.
Web3 account wallet
You need to pass the private key that generates the from
address.

Answered 2021-Jun-12 at 08:36This is normal. I don't know why binance does not fix this, but as API doc say you should ignore it.

If the quantity is 0, remove the price level.
QUESTION
I am trying to use the binance_async
library, tokio
, and futures
to make concurrent orders to Binance. (See notes at the end of this question.)
The binance_async
functions I'm using return a
binance_async::error::Result>
type. I am facing the following issue, illustrated in these 2 examples:
- Say I'm trying to do this:
ANSWER
Answered 2021-Jun-11 at 18:22binance_async
uses futures 0.1, which is incompatible with the now standardized std::future::Future
that tokio
uses. You can convert a futures 0.1 future to a standard future by enabling the compat
feature:
QUESTION
Is there a specific binance futures API endpoint with which you automatically close all positions? There is such an option in the GUI. Right now I can only imagine getting amounts of all positions and than selling that amount, but is there an easier way?
Preferably I would like to be able to call in either the ccxt library or the python-binance library.
...ANSWER
Answered 2021-Jun-09 at 13:17Binance API has a DELETE /fapi/v1/allOpenOrders endpoint that requires a pair symbol.
ccxt wraps this endpoint in the cancel_all_orders() function, which requires a pair symbol as well.
So at least you don't have to loop through all positions. But you'll need to loop through all pairs. Or just the pairs with open orders, if you have this information.
QUESTION
I was wondering if there's a PancakeSwap API, that allows me to swap BNB for a token, and if it isn't possible, can I do it with Binance Smart Chain's API?
Thank you!
...ANSWER
Answered 2021-Apr-25 at 07:08pancakeswap currently doesn't have APIs or sdk as Uniswap sdk. Best solution is connect to binance smart chain and connect to the pancakeswap router contract through web3.
