^{Originally posted by **DerXanRam** September 22, 2023} 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 GasLimit is 0x42c23 value is 0x2386f26fc10000 ToAddress is 0x1111111254eeb25477b68fb85ed929f73a960582 ``` The ABI data is `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` and this is the raw tnx generated `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` any encoding error ?Please help :pray:

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 :smile: ... the gas fee are very small and i covered it($0.15)

[mhw0]

Is 0xC4a13DA00881cBdaD2285e10aCe80dBF458aDd49 your address?

[DerXanRam]

Is 0xC4a13DA00881cBdaD2285e10aCe80dBF458aDd49 your address?

No. It isn't my address

[DerXanRam]

Is 0xC4a13DA00881cBdaD2285e10aCe80dBF458aDd49 your address?

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

[mhw0]

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

[mhw0]

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

[mhw0]

hopefully it's not secp256k1 deserialization issue

[DerXanRam]

i hop...... I will close this isse... if it is related i will reopen it. Thanks for ur reply :pray:

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)

please help :pray:

[mhw0]

Hey. Thanks for the detailed explanation. I'll need some time to fix this problem (just don't have free time right now). Thanks!

[mhw0]

If you have a fix for this, do not hesitate to open a PR :)

Ok thanks very much bro :pray: ... i hop u will fix it soon.... my entire project is highly depend on this lib :smile:

[DerXanRam]

If you have a fix for this, do not hesitate to open a PR :)

I' pretty new for blockchain programming... but i will try my best

[mhw0]

Hello @DerXanRam Can you reproduce this error using hardhat?

[DerXanRam]

Hello @DerXanRam Can you reproduce this error using hardhat?

I didn't use hardhat before....to replicate the error put some balance in ur wallet and try to send raw transaction (send token approval transaction...it costs only 4 or 5cents) and u can replicate the issue

[mhw0]

Okay, let me actually test it on local node

[mhw0]

I can't reproduce the error on local node. Are you sure that all the arguments are correct?

[DerXanRam]

I can't reproduce the error on local node. Are you sure that all the arguments are correct?

yeaa... i try the same input on python code i found from the internet and the transaction works

[mhw0]

I can't reproduce the error on local node. Are you sure that all the arguments are correct?

yeaa... i try the same input on python code i found from the internet and the transaction works

Can you please show me the whole code? (with the same secret and transaction arguments)

please help 🙏

this is the code and test account PK and address... and I'm trying to send "approve" transaction

[mhw0]

Yeah, but I can't see the nonce, gasprice, gaslimit etc.

[DerXanRam]

Yeah, but I can't see the nonce, gasprice, gaslimit etc.

Sorry for my late replys... it is mid night and i fall in a sleep 🙏

[DerXanRam]

I will send it tomorrow ... pls🙏

i use gas=150000

[mhw0]

Okay, I think I can't reproduce the issue as it's just "random" thing. Are you still getting this thing with that transaction? What if you remove the call part and tansfer some eth?

[mhw0]

Oh, could you please try eth_keccak256p instead of eth_keccak256? Maybe prefix issue?

[DerXanRam]

ok i will try to transfer,,

[DerXanRam]

Oh, could you please try eth_keccak256p instead of eth_keccak256? Maybe prefix issue?

Finally worked :+1: by changing eth_keccak256 to eth_keccak256p >>> thanks a lot man :pray:

[mhw0]

Closing the issue. Thanks!
