I'm trying to swap on Binance Smart Chain(which this library also works for it) using 1inch dex. But it says sometimes
"message":"insufficient funds for gas * price + value"
and some times
"message":"INTERNAL_ERROR: insufficient funds"

even if i have fund in my account to do the swap and cover the gas. all my balance is BNB and i'm swaping BNB(0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee) to BUSD(0xe9e7cea3dedca5984780bafc599bd69add087d56).

this are the values used in making the raw tnx

nonce=0x1
gasPrice is 0xd09dc300

ToAddress is 0x1111111254eeb25477b68fb85ed929f73a960582

any encoding error ?Please help 🙏

Hi @DerXanRam Have you checked your balance? or "gas * price + value" value?

Answer 2 · 2023-09-22T19:10:03.000Z

Hello bro... i noticed i didin't encode the value...but even if i encoded the value and check the tnx on this site, value is still zero and through the previous error... take a look at the code

Hi @DerXanRam Have you checked your balance? or "gas * price + value" value?

yeaa i have enough balance... i even do manual swap to check BNB is gas payment on BSC 😄 ... the gas fee are very small and i covered it($0.15)

Is 0xC4a13DA00881cBdaD2285e10aCe80dBF458aDd49 your address?

No. It isn't my address

Is 0xC4a13DA00881cBdaD2285e10aCe80dBF458aDd49 your address?

And sorry for my late reply... it was midnight and i fall in a sleep

Answer 7 · 2023-09-23T16:09:33.000Z

Okay, that's strange. This might be signature (v,r,s) issue.

Answer 8 · 2023-09-23T16:10:10.000Z

any idea what can cause this?

I think i found the problem.... after calculating v, r, s i used rlp0 instead of rlp1. and aslo the zero value next to assigning value must be removed. After this i can see value when i decode the tnx hash.... but still the problem exist..... progressing

Hello bro ... after long try and error, also research.... i found that the rlp function has a bug, which it doesn't encode the tnx correctly.... u can see the previous tnx hashes and also the below one, my address is 0xb438D71c1E6E8E53637e1F1deC37c2E635e335fc but when u decode the transaction using this site the from address is not encoded correctly. i.e in the below tnx hash the address encoded is 0xC4a13DA00881cBdaD2285e10aCe80dBF458aDd49 but must be 0xb438D71c1E6E8E53637e1F1deC37c2E635e335fc .... i correctly added my private key like this (real account with no balance just to show how i pass the private key)

the private key from meta mask
