After EIP-2718 when the new tx types were added, the “consensus encoding” of a transaction (and receipt) is not a pure RLP encoding except for the legacy transaction. For non-legacy tx/rct types it is an RLP encoding of the tx/rct + prepending it with a specific prefix. This is encapsulated in the new tx.MarshalBinary and rct.MarshalBinary methods. https://github.com/cerc-io/ipld-eth-server/blob/v5/pkg/eth/api.go#L470 and other usages of rlp.EncodeToBytes to encode transaction and receipts need to be replaced with tx.MarshalBinary or rct.MarshalBinary.
