Hi! When I use truffle console it automatically loads contracts from the current directory, is there a command to load contracts on other directories?

Hi all. I'm following a tutorial that inside a test validates a BigNumber instance using Chai. I can console log both variables console.log(decimals); and console.log(web3.utils.toBN(_decimals)); which results in the exact same string: BN { negative: 0, words: [ 18, <1 empty item> ], length: 1, red: null } and BN { negative: 0, words: [ 18, <1 empty item> ], length: 1, red: null }. However when I add the following check: decimals.should.be.bignumber.equal(web3.utils.toBN(_decimals)); the following exception is thrown: AssertionError: expected <BN: 12> to be an instance of string, number or BigNumber. Can anyone explain what I'm missing here?

Hi! I have an issue. Is it possible to integrate @truffle/contract library in Angular 13 project? At the moment I get the following error when I try to include "var contract = require("@truffle/contract");" into an component (*.ts file):
"BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need this module and configure a polyfill for it."

Is ganache ui supported anymore? I saw the last commit was in 2020

@roshkins I think it is working in progress... in 2.6.0?

Hello, I am having trouble with running 'truffle test' in the terminal on my contract. When I run a test I keep receiving the error "TypeError: pollInstance.createPoll is not a function." I am unsure of how to fix this given that I declared my artifacts variable at the beginning of the test file and I declared a deployment of my "PollFactory" contract before each test. Does anyone know how to deal with this error?

Hi all, getting this error during migrations rlp: value size exceeds available input length.

Is this a contract size issue? Network is Celo (Baklava testnet). Same migrations works perfectly fine on Celo (Alfajores testnet).

hello

I'm trying to deploy to polygon with a config that is used to work. I'm already willing to pay a high fee, but nothing works.

matic: {
      provider: () => new HDWalletProvider({
        mnemonic: {
          phrase: process.env.MNEMONIC
        },
        providerOrUrl: 'https://rpc-mainnet.maticvigil.com/v1/<ny',
      }),
      network_id: 137,
      confirmations: 2,
      timeoutBlocks: 2000,
      gas: 10000000,
      gasPrice: 150000000000,
      networkCheckTimeout: 10000000,
    },

Is there something wrong here?

Hey everyone. I hope this is a quick question. I'm working on a personal project to use an ERC20 token to pay gas prices. I'm trying to use OpenGSN (find it here: https://opengsn.org/). OpenGSN works by wrapping the web3 provider, so I'll need to update the provider in truffle-config.js for my network. The problem is that the function OpenGSN provides to create a provider is asynchronous (returns a Promise). Does truffle-config.js support Promises for the provider setting?

@d_avantgarde_twitter have you tried using Infura or alchemy instead of maticvigil ?

I had the same issues with truffle... I'd recommend switching to hardhat

the hardhat config for polygon is dirt simple...

polygon: {
url: POLYGON_MAINNET_RPC_URL,
accounts: [PRIVATE_KEY],
saveDeployments: true,
},

RPC_URL pointing at Alchemy API in my case..

works great!

depoyed to Eth, rinkeby, kovan, polygon and mumbai with hardhat.. i really struggled with truffle.

Hello all,

I am trying to deploy my contract to Polygon mainnet. But getting this error
Saving migration to chain.Error [ERR_UNHANDLED_ERROR]: Unhandled error. ({
code: -32603,
message: 'ESOCKETTIMEDOUT',
data: { originalError: { code: 'ESOCKETTIMEDOUT', connect: false } },
stack: 'Error: ESOCKETTIMEDOUT\n'
I can see the transaction in polygonscan, but the migration is not getting saved.

So I don't understand the decision to have truffle test require a separate migration step. Looking at the examples it seems that truffle has all the information it needs to deploy the contracts used by the test to local developer instance. I particularly don't understand how is supposed to work with constructors. Does my migration for testing need to call all constructors as would be used in the test
