Solidity – How to Fix Invalid Address and Capitalization Checksum Errors

blockchainsoliditytransactions

Can anybody please help me fix this error? I do not know why it happens:

Error: Provided address is invalid, the capitalization
checksum test failed, or its an indrect IBAN address which can't be
converted

I tried it on remix and it works

It it may help, I have the same error with the following function :

function addpartner(address partner, uint percent) {}

The error disappears if I switch the parameters :

function addpartner(uint percent, address partner) {}

It doesn't explain the error's origin, but you could try to switch your _a and _id parameters. May be a etheratom bug ?

txin your example is the transaction hash. Function getTransactionCount(...), however, needs an account as parameter.This is what is recognized, therefore the error.

If you want to get more information on the transaction, use web3.eth.getTransaction(tx). Here, tx has to be the transaction hash.

My guess would be Users[_token][_user] wasn't actually set then the operation user.totalAmount -= _amount; resulted in an underflow (i.e. 0 - 50000)

It costs some gas, but maybe just put a simple require:

require(user.totalAmount >= _amount, "Empty wallet");
