Example EIP 1559 TX

[benwilliamson86]

Is there an example eip 1559 tx for ethers? Not sure that I am setting the msg variables correctly. Thanks.

Fo the most part you shouldn't need to do anything special, ethers will detect if the network is EIP-1559 and automatically populate things for you.

If you wish to explicitly set it, you can pass in type: 2, à la:

signer.sendTransaction({
  to: "ricmoo.firefly.eth",
  value: parseEther("1.0"),
  type: 2
});

If you examine your transaction on Etherscan, it will indicate the transaction type (2 meaning EIP-1559).

Thanks. I understand that the gasPrice is set by the network for eip 1559 but is it beneficial to set maxfeepergas and maxpriorityfeepergas?

You should not set gasPrice any more. You may optionally specify a custom maxFeePerGas and maxPriorityFeePerGas, but by default ethers will populate those for you, using provider.getFeeData().
