Summary

In EIPs, it said:

• EIP-2930 requires EIP-2718, EIP-2929.
• EIP-1559 requires EIP-2718, EIP-2930.

Axon transactions support EIP-2930 and EIP-1559:

axon/protocol/src/types/transaction.rs

Lines 21 to 25 in c7a471b

	pub enum UnsignedTransaction {
	Legacy(LegacyTransaction),
	Eip2930(Eip2930Transaction),
	Eip1559(Eip1559Transaction),
	}

But Axon receipts not support EIP-2718.

Details

According to EIP-2718:

Receipt is either TransactionType || ReceiptPayload or LegacyReceipt.
... ...
LegacyReceipt is kept to be RLP encoded bytes; it is rlp([status, cumulativeGasUsed, logsBloom, logs]).
... ...
ReceiptPayload is an opaque byte array whose interpretation is dependent on the TransactionType and defined in future EIPs.

As EIP-2930 defined: if TransactionType is 1, ReceiptPayload is rlp([status, cumulativeGasUsed, logsBloom, logs]).

As EIP-1559 defined: if TransactionType is 2, ReceiptPayload is rlp([status, cumulative_transaction_gas_used, logs_bloom, logs]).

Anything else?

It's almost impossible to verify a Axon receipt with receipts root:

• Axon receipts not support EIP-2718.
• Without EIP-2718, the RLP-serialised LegacyReceipt also is incorrect (ref: The RLP implementation of receipt is incorrect #1259).
• Even users use the Axon-specific RLP-serialised of receipts, the receipts_root is still could be verified since the incorrect LegacyReceipt is not used when calculates receipts_root (ref: The implemention of receipts root in block is incorrect #1258).
