Summary: Using truffle to deploy to rinkeby via infura.

I just deployed my crowdsale and that seems to succeed. However truffle is not showing me a contract address which is worrying. I notice Migrations dry-run (simulation) at the top, which makes me wonder if its not being deployed, its just testing it... is this a thing? How do i get it to actually deploy?

OK as this was hard to debug, I have an answer that may help others.

  1. Using the latest bleeding edge truffle, I was informed through a warning, to use the 1.0.0-web3one.0 version of truffle-hdwallet-provider
  2. Once I installed that, I could get past the simulation. When migrating for the rinkeby/live networks, a simulation will be attempted before actual deployment. This didn't seem documented anywhere and as truffle hung after simulation completed, this was a real brainer....
  3. Although it seems obvious now, if there is any time related code (such as a start time for a crowdsale) this needs to be minutes into the future for deployment. Not something obvious when using ganache - I had mine 20 seconds into the future, but by the time that would have been deployed, that was now in the past, causing a revert on my contracts

I'm making quite good progress with the new 1.0 version of ethereum tools, and beta of truffle, so shout if I an be of assistance!

Please try put it in the networks section, the option skipDryRun: true

module.exports = {

  networks: {

     provider: () => new HDWalletProvider(mnemonics, endpoint),
     network_id: 3,
     gas: 5000000,
     confirmation: 2, 
     timeoutBlocks: 200,
     skipDryRun: true

Mastering Blockchain Programming with Solidity: Write , Write production-ready smart contracts for Ethereum blockchain with Solidity you to dry-run the migration locally before performing the actual migrations on a For each network configuration, you should either define host/port or provider,​  Running various Truffle commands allows us to test our smart contracts in real time: truffle compile, truffle test or truffle migrate will all summon the Solidity compiler to compile the latest

You can use Etherlime for deployment of smart contracts. Actually you can use it for everything instead of truffle. It is simpler and with more information. In my opinion is the better tool. It is based on ethersjs which is a lot better than web3js. Here is a link to the documentation

Truffle | Truffle Commands | Documentation, Run a console with contract abstractions and commands available. Create a new artifact where artifact_type is one of the following: contract, migration or test. test. Run JavaScript and Solidity tests. truffle test [<test_file>] [--compile-all]  truffle migrate --reset --network rinkeby it shows migrations dry-run, 1_initial_migration.js and 2_deploy_contracts.js shows block number ,timestamp, totl sent like that. Then when starting migrations 1_initial_migration.js has transaction hash and blocks still be loaded and not finished.

Hands-On Smart Contract Development with Solidity and Ethereum: , You should run a client (like ganache-cli, Geth, or Parity) in a separate times out // (minimum/default: 50) // skipDryRun: true // Skip dry run before migrations? $ truffle migrate --dry-run Under the hood, this feature forks from your chain of choice to create a new sandbox to run your migrations. This sandbox has access to all the code, addresses, accounts and balances as the old chain, with all new transactions occurring within the sandbox.

Truffle | Running Migrations | Documentation, Migrations are JavaScript files that help you deploy contracts to the Ethereum network. make sure to have a test blockchain such as Ganache installed and running before pragma solidity ^0.4.8; contract Migrations { address public owner; You can optionally pass an array of contracts, or an array of arrays, to speed up  Note 3: By default Truffle does a dry-run before deploying for real when you deploy to a testnet or mainnet. If you don’t want this behavior, add a --skipDryRun flag. Truffle console. The Truffle console is a REPL to interact with your smart contracts.

truffle migrate does a "--dry-run" by default. Can't deploy on network , I can't deploy on network anymore because dry-run is used by I use: truffle migrate --reset --network=sokol Result I got: Migrations dry-run Solidity - 0.4.25 (solc-js) If you'd like to skip the dry run for now, you can add skipDryRun: true When using --skipDryRun truffle exit after compiling the contracts  "Migrations" ran out of gas (using Truffle's estimate.) * Block limit: 0x50e7c * Gas sent: undefined * Try: + Setting a higher gas estimate multiplier for this contract + Using the solc optimizer settings in 'truffle-config.js' + Making your contract smaller + Making your contract constructor more efficient + Setting a higher network block

  • Share your contract, truffle.js, Truffle version you use and the command you just ran.
  • I'll check your migrations scripts, are you using async/await or promises? There's an open issue about it
  • Hey guys, thanks, have answered my own question
  • How did you get the warning? I was having the same problem with truffle-hdwallet-provider ^1.0.5 and after changing the version to 1.0.0-web3one.0 it started to work.
  • Suggesting someone use another tool isn't really helping them to fix the problem.
  • Why not? Have you tried deploying contracts to the mainnet using Truffle? My suggestion will fix their problem and make their life a lot easier.
  • Because you don't know the reasons why they have chosen to use the tool, there may be business reasons or other technical reasons why they've chosen to use the tool that they have. Suggesting they just change instead of trying to fix the problem isn't a help.
