The ganache local node implements a few debugging/test methods that the hardhat local node does not such as the following:

  • evm_mineBlockNumber, params: [blockNumber]
  • evm_setTime, params: [unixSeconds]
  • evm_freezeTime, params: [seconds]
  • miner_start
  • miner_stop

How can the behaviour of these methods be replicated in hardhat?

You can take a look at this hardhat doc to find some of the corresponding methods and their helpers here:



  • Thanks for this, though I couldn't find any equivalents to evm_freezeTime, miner_start and miner_stop. evm_setTime can be emulated using increaseTo(newTimestamp), evm_mineBlockNumber can be using mineUpTo(blockNumber);
