Metamask is not pop up for the Approve and Swap

Technical Issue Reporting
#9

In the amount field we need to pass the value of amount we want to swap not the value of the token we want to receive. correct?

#10

as per the link I am doing in the right way. as I am trying 0.0001 and 18 decimals and that is equal to 100000000000000
so, what is wrong in the request?

#11

Absolutely right, the problem is that you are trying to swap tokens you donā€™t have.

#12

Your wallet has only PDX tokens

#13

WBNB - is an ERC20 token wrapped BNB, it has own smart contract and address 0xbb4cdb9cbd36b01bd1cbaebf2de08d9173bc095c

BNB is a native crypto without contract address(for 1inch you can use 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE )

In my wallet I have both the BNB and PDX.

#15

I have tried with given contract address.
Request:

{ā€œchainā€:ā€œbscā€,ā€œfromTokenAddressā€:ā€œ0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeEā€,ā€œtoTokenAddressā€:ā€œ0x43a0c5eb1763a211aa3c05849a617f2ee0452767ā€,ā€œamountā€:100000000000000,ā€œfromAddressā€:ā€œommitedā€,ā€œslippageā€:1,"_ApplicationId":ā€œC0x6JlYQmzWQ1AO9Lnr2kCDyJGVApfyUJErEGrT9ā€,"_ClientVersion":ā€œjs0.0.68ā€,"_InstallationId":ā€œ1f2476fd-514c-4f11-bc5d-86ce541dae48ā€}

Response:

{ā€œresultā€:{ā€œstatusā€:200,ā€œdataā€:{ā€œsuccessā€:true,ā€œresultā€:{ā€œstatusCodeā€:500,ā€œmessageā€:ā€œcannot estimateā€,ā€œerrorā€:ā€œInternal Server Errorā€}}}}

#16

did you try to change from PDX to BNB?

#17

Yes Tried both the option and getting

{ā€œresultā€:{ā€œstatusā€:200,ā€œdataā€:{ā€œsuccessā€:true,ā€œresultā€:{ā€œstatusCodeā€:500,ā€œmessageā€:ā€œcannot estimateā€,ā€œerrorā€:ā€œInternal Server Errorā€}}}}

Hey @bullish

Works fine for me:

const quote = await Moralis.Plugins.oneInch.quote({
          chain: "bsc", // The blockchain you want to use (eth/bsc/polygon)
          fromTokenAddress: "0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE", // The token you want to swap
          toTokenAddress: "0x43a0c5eb1763a211aa3c05849a617f2ee0452767", // The token you want to receive
          amount: 100000000000000
        });
        console.log(quote);

I just want to say that sometimes it will return you deifferrent error messages like ā€œInternal errorā€ because of a small amount to swap.

For example:
amount: 10000 - { ā€œstatusCodeā€: 500, ā€œmessageā€: ā€œInternal server errorā€ }
amount: 100000000000000 - works fine

#19

Also you can check returns from 1inch swagger https://api.1inch.exchange/swagger/binance/#/Swap/SwapFactoryCommonController_getQuote

#20

Issue is with swap not with quote endpoint.

#21

Increase slippage. For me it showed correctly with slippage 10

Hi Yomoo,

Can you please paste the request here, which you are trying at your end?

#23 
async function inch() {
        await Moralis.initPlugins();
        const swap = await Moralis.Plugins.oneInch.swap({
          chain: "bsc", // The blockchain you want to use (eth/bsc/polygon)
          fromTokenAddress: "0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE", // The token you want to swap
          toTokenAddress: "0x43a0c5eb1763a211aa3c05849a617f2ee0452767", // The token you want to receive
          amount: 100000000000000,
          fromAddress: "0xCE8B75302AB72FC366B62557cFcbB43f3d4bd40F", // Your wallet address
          slippage: 10
        });
      }
#24

In fromAddress was my address and it popped up metamask :man_mechanic:

#25

As I mentinoned before, you can check the 1inch API swap

#26

Hi Yomoo,

Above request is working fine with my wallet address but when I am trying for inverse option i.e. trying to swap 200 PDX to BNB it is throwing 500 error.

here is the request:

{
	"chain": "bsc",
	"fromTokenAddress": "0x43a0c5eb1763a211aa3c05849a617f2ee0452767",
	"toTokenAddress": "0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE",
	"amount": 200000000000,
	"fromAddress": "omitted",
	"slippage": 20,
	"_ApplicationId": "C0x6JlYQmzWQ1AO9Lnr2kCDyJGVApfyUJErEGrT9",
	"_ClientVersion": "js0.0.68",
	"_InstallationId": "1f2476fd-514c-4f11-bc5d-86ce541dae48"
}

Also for this endpoint oneInch.hasAllowance is not behaving correctly. although I have approved the token it is giving false and sometimes true

#27

I checked your logs. You have called hasAllowance for different token_addresses and wallet_addresses

Iā€™ve tried to figure out the problemā€¦ but without any success. If you try to get this data from 1inch swagger you will recieve the same error, so the problem is on 1inch side. We canā€™t really help you with it :cry:

#28

But it will work correctly for wbnb. I guess the problem is because of wrapping the bnb
