Describe the bug

I have a simple script to deploy a contract. This script executes successfully on Goerli and Arbitrum Rinkeby, but it fails on Arbitrum Goerli with (code: -32000, message: intrinsic gas too low, data: None)

I have tried Alchemy RPC + public RPC (https://goerli-rollup.arbitrum.io/rpc/)

Very weird that Arbitrum Rinkeby works, but Arbitrum Goerli does not. They both run Arbitrum Nitro ... perhaps Goerli is running a newer version since Rinkeby is deprecated...?

Also, I tried increasing the gas price and gas limit by many multiples, but that didn't change anything. And I have more than enough ArbGoerli ETH in my EOA.

The transaction requests are identical between rinkeby and goerli, aside from the nonce, but I also tried using a fresh account with nonce = 0 on goerli and that also didn't change anything:

      "transaction": {
        "type": "0x00",
        "from": "0x...",
        "gas": "0x1c60d2",
        "value": "0x0",
        "data": "0x...",
        "nonce": "0x0"
      },

Full output:

==========================

Estimated total gas used for script: 1859794

Estimated amount required: 0.0001859794 ETH

Also, just tried a simple forge create and that works successfully
forge create Factory --rpc-url arbitrum-goerli

Ok I managed to get the script working...

I had to pass --skip-simulation

The estimated gas usage with simulation was 1,859,794

Without simulation, the gas limit was set to ~20M while the gas used was ~14M

So the gas estimation is off. Does forge estimate gas with the local EVM (rEVM?)? Does it call out to the provider?

@joshieDo do you remember if there is an issue with the arbitrum gas calculation logic? this has been increasingly common

It should be calling out to the provider

foundry/cli/src/cmd/utils.rs

Lines 165 to 168 in fb4a836

	pub fn has_different_gas_calc(chain: u64) -> bool {
	if let ConfigChain::Named(chain) = ConfigChain::from(chain) {
	return matches!(chain, Chain::Arbitrum | Chain::ArbitrumTestnet)
	}

Yeah that explains it. We only have one Arbitrum testnet, we need to add Chain::ArbitrumGoerli .

--skip-simulation works because it's during the simulation that we calculate the gas usage. With the flag, we ask the provider for the gas estimation.

this fixed the same issue i was having with arbitrum mainnet

--skip-simulation solved this issue for me on Mantle as well.
