I am trying to deploy a contract using the following code: const Contract = await ethers.getContractFactory("Contract", { libraries: { UtilsLibrary: "0xF...e", } }); let pool = await Contract.deploy({gasLimit: 10000000, gasPrice: ethers.utils.parseUnits("1", "gwei")}) When I run this on Kovan, Goerly, Arbitrum Goerly, this works totally fine (obviously I correct the library address). When I run this on the Arbitrum mainnet I get an error saying "not enough funds for gas". I have changed multiple RPCs and result is not luck. Contract takes about 5 mil gas to deploy and I have about 1 ETH in wallet. I really have no more ideas on what might be wrong here. Any suggestions appreciated. UPD: I have deployed the UtilsLibrary totally fine as part of the script as well. So the correct signer is being used and it has funds.....

I had to increase the gas limit to 100mil and it took 80 mil to deploy. I am not sure why similar transaction only took 5mil on kovan and Arbitrum testnet

Arbitrum has a different way to compute gas cost, see here https://developer.offchainlabs.com/docs/Differences_Overview#fee-stats In particular, calldata is more expensive than L1, and this explains the contract deployment extra cost.
