[Ethereum] Can’t deploy from Remix – network does not support EIP-1559

1. Go here and generate a 12 word mnemonic, for "Coin" select ETH.
2. Save the mnemonic (the 12 words), and, lower down the page, the first address (derivation path ending with 0) and private key somewhere safe.
3. Transfer some ETH from your account to the one that corresponds to the mnemonic you just generated. You can import it into MetaMask with the private key and later return the unused ETH.
4. Use this tutorial to deploy your smart contracts through truffle, of course don't forget to replace the mnemonic from the tutorial with the one you just generated.
5. Adjust the Provider URL in the tutorial with your personal access URL you received in the mail from infura, also, in the network configuration of the code example of the tutorial, change "ropsten" to "mainnet".

then do truffle migrate --mainnet --dry-run (only available in v4beta, but a good habit) to check, if everything is fine, and then truffle migrate --mainnet.

EDIT: Of course you're also free to use the mnemonic from MetaMask.

I was also struggling with this previously. This error occurs with users using Metamask with Ledger/Trezor.

It appears that more recent versions of web3js is requiring Metamask to strictly send txs as EIP1559 txs, although Ledger does not support EIP1559 txs with Metamask just yet.

Metamask have rolled out EIP1559 + Ledger support on version 10.1.0 (https://github.com/MetaMask/metamask-extension/releases/tag/v10.1.0). This should resolve the issue which you're facing. Users could directly update to that version on Chrome already, though still waiting for rollout to Firefox extensions.

Alternatively you could drop the web3js package version to something older (e.g. 1.2.x), though that has its own quirks.

Last I've tested, this also affected other tooling like InstaDapp and Remix.
