Fixed

Known issues

• Broken validation in web3.py prevents sending locally signed EIP-1559 transactions. Patch available here https://github.com/ethereum/web3.py/pull/2099
• chain.priority_fee is provisional, you can use it with this patch https://github.com/ethereum/web3.py/pull/2100 and with Erigon built from devel branch
• Hardhat uses chain.id 31337 by default even in forked mode. If you rely on it, you need to add chainId: 1 to hardhat.config.js. We work with Hardhat on a better fix here https://github.com/nomiclabs/hardhat/pull/1592
