"value": w3.toWei(12, "wei"),
"gas": 21000,
"gasPrice": w3.toWei(1, "gwei"),
"chainId": "0x4",
}
signed_tx = client.sign_legacy_transaction(tx, key_id)
tx_hash = w3.eth.sendRawTransaction(signed_tx)

"gas": 21000,
"maxFeePerGas": w3.toWei(1, "gwei"),
"maxPriorityFeePerGas": w3.toWei(1, "gwei"),
"type": "0x2",
"chainId": "0x4",
}
signed_tx = client.sign_dynamic_fee_transaction(tx, key_id)
tx_hash = w3.eth.sendRawTransaction(signed_tx)
