Newbie to Ethereum NFT contract deployment here. So please bear with my questions. I am trying to deploy a ERC-721 contract to ETH Mainnet and I have 0.285 ETH in my wallet. But I am still getting insufficient funds error. The contract is not very complicated and we were able to deploy same 3 months ago.

Am I making any rookie mistake in setting these values in my truffle_config?

Error: "Migrations" could not deploy due to insufficient funds

  • Account: 0x714D..........
  • Balance: 285585911447858493 wei
  • Message: insufficient funds for gas * price + value -- Reason given: Custom error (could not decode).

Command: truffle deploy --network mainnet

truffle-config.js:

mainnet: {
  provider: () => new HDWalletProvider(mnemonic, `https://mainnet.infura.io/v3/${INFURA_APP_KEY}`),
  network_id: 1,
  confirmations: 2,   
  timeoutBlocks: 200,  
  gasPrice: 22000000000, //22 gwei
  gas: 59000000000,//59 gwei,
}, 

Thanks!

The gas limit you are using is too much. If you calculate the amount of ETH needed is around 1200ETH. EG

Deployment Fee (DF) = gasLimit * gasPrice + value
DF = 59000000000 * 22000000000 + 0
Total ETH = DF/1e18 = 1298 ETH

The gas limit should not be in gwei. Try using less gasLimit like 300000 or 500000 then

DF = 400000 * 22000000000 = 0.0088 ETH

  • Hello @Safi, Thank you for your reply. The current gas price was 43 GWEI and my transaction keeps running out of gas even if I set a gas price above the current price such as code' mainnet: { provider: () => new HDWalletProvider(mnemonic, mainnet.infura.io/v3/${INFURA_APP_KEY}), network_id: 1, confirmations: 2, timeoutBlocks: 200, gasPrice: 45000000000, gas: 2000000, //maxFeePerGas: 21000, //maxPriorityFeePerGas: 1000, }, code` ---------------------------------- Please help.

  • try increase gas: 3000000 this will cost you approx. 0.13 ETH. This is too high to deploy a contract. Why don't you try remix.ethereum.org to deploy?
