Answering my question here. Based on @Gari Singh's answer above the certificate that you have to use in the "tlsCACerts" parameter in the connection.json file has to be created by combining the intermediate and root CA into a single file. The first block in the file should be the intermediate CA and the second block should be the root CA. This certificate chaining is required because the intermediate CA is signed by the root CA and the client should pass both so that they can be validated properly. Comprehensive explanation can be found here: https://www.thesslstore.com/blog/root-certificates-intermediate/

The final thing that I was missing because of which I was getting the error "Failed to evaluate transaction: Error: Committer must be connectable" was that I was passing 3 orderers in the "channels" section of the config and only passing one of their details in the "orderers" section of the config. Adding the ip and other details for the other 2 orderers took care of that issue.

How to resolve "Internal error" from web3.eth.Contract.MyMethod.estiamteGas

Asked 2021-May-18 at 21:30

I have a call to estimateGas from an Express server to a private Hyperledger Besu chain and everything was working fine yesterday, yet today when I run the same method it's returning "Error: Returned error: Internal error". Nothing changed in the code between yesterday and today, and I'm lost as to where to even start troubleshooting.

That is the extent of the error, nothing more descriptive is given, and after googling for hours, I haven't found anything that could help. The stack trace points to the error handler file in the web3 node module.

Code (actual methods and parameters omitted for security reasons):

ANSWER

Answered 2021-May-18 at 21:30

It can be a problem on your web3 provider, but more likely option is that executing of the myMethod() would result in reverting the transaction - that's why it probably throws the error.

You can encapsulate the method in a try/catch block to catch the error message.

How to manually burn tokens on BSC network

Asked 2021-May-12 at 13:04

I have a token contract deployed on Binance Smart Chain and want to burn some of the tokens manualy, thus to execute following function call from some kind of console.

...

ANSWER

Answered 2021-May-12 at 13:04

If the burn() function has a public or external visibility modifier, you can execute it by submitting a transaction containing the function signature and the argument value(s) in the data field.

One of the ways is to build the data field value manually or semi-manually

Best practice for protecting sensitive information on solidity?

Asked 2021-May-09 at 20:16

I have a field in my contract. It's something like this:

...

ANSWER

Answered 2021-May-09 at 20:16

If it's on a public blockchain (mainnet, ropsten testnet, ...), it's always going to be accessible by querying the storage slot containing the secretField value from an off-chain app. No matter the Solidity private visibility modifier because the storage query is performed on a lower layer.

Example: If secretField is the first property of the first defined contract (on this address), its value is stored in storage slot 0.

But if you only want to hide it from on-chain requesters, you can keep the property private and require the getter to be accessed only from a certain address.

Install a Web3.js middleware layer that signs transactions locally, instead of sending a JSON-RPC method to Infura.

ANSWER

Answered 2021-Apr-15 at 20:08

1. Does --opcodes just give a more compact form of assembly code compared to --asm output?

That's somewhat correct. You could still translate the assembly to opcodes and get the same result.

Assembly represents a set of "low level-ish" instructions. Opcodes are the "real" binary instructions passed to the EVM. See for example this table that translates the opcodes to binary.

2. PUSH1 0x80 PUSH1 0x40 MSTORE in --opcodes format vs. mstore(0x40, 0x80) in --asm format. Are they doing the same thing? (I guess so but not 100% sure...)

Yes, they are doing the same thing - see answer to 1. When you run this snippet in Solidity

QUESTION

I am having a difficulty of understanding interfaces in Solidity. What am I missing?

Asked 2020-Nov-08 at 03:30

I came from Java OOP background and understand interfaces.

Currently working on a simple budgeting app (https://github.com/compound-developers/compound-supply-examples) that takes ETH or Stablecoin and put in in Compound and earn interest.

My confusion is how Solidity Interfaces are used. I came from OOP (Java) background and very familiar with interfaces.

So in this code(MyContracts.sol) you can see that there is a mint() function in the interface. However, there is no implementation for it but you can see that it's used here uint mintResult = cToken.mint(_numTokensToSupply); without any implementation.

Can anyone shade some lights on how interface functions are used without implementations ? When you call mint in this case, which code is actually being executed ?

ANSWER

Answered 2020-Nov-08 at 03:30

I created a smart contract that should execute a function after its called by two owners, if and only if both owners call for function X, then this function is performed. It's like a multi signature type. My code is below, but its still not operational. The contract should send 1 Ether to the Wallet account after its called by the two Owners.
