108-143: Fix RLP decode/encode field order mismatch.
decode_fields()attempts to decodetx_hashas the second field, butencode_fields()andfields_len()omit it entirely. This breaks RLP decoding viaRlpEcdsaDecodableTxsince the encoded data contains 7 fields while the decoder expects 8, causing all subsequent fields to be read from wrong byte offsets.The correct behavior is shown in the
impl DecodableforTxL1Msg(lines 274–311), which properly decodes the 7 fields and setstx_hashtoB256::ZEROwith the comment "For L1 messages, the hash is typically computed externally."Fix: align decode_fields with encode_fields
pub fn decode_fields(buf: &mut &[u8]) -> alloy_rlp::Result<Self> { Ok(Self { queue_index: Decodable::decode(buf)?, - tx_hash: Decodable::decode(buf)?, + tx_hash: B256::ZERO, nonce: Decodable::decode(buf)?, gas_limit: Decodable::decode(buf)?, to: Decodable::decode(buf)?, value: Decodable::decode(buf)?, input: Decodable::decode(buf)?, from: Decodable::decode(buf)?, }) }

In `@crates/chainspec/src/morph_hoodi.rs`:
- Around line 33-40: The test hardcodes timestamp 0 but MORPH_HOODI's Bernoulli
activation isn't at 0; update the test to use the actual configured activation
time instead of 0: query the Bernoulli activation timestamp from the morph hoodi
config (the value defined on MORPH_HOODI / its hardfork schedule) and assert
MORPH_HOODI.is_bernoulli_active_at_timestamp(activation_ts) (or adjust
genesis/hardfork schedule in the MORPH_HOODI definition if the intent is to have
it active at 0). Use the existing symbol MORPH_HOODI and the
is_bernoulli_active_at_timestamp helper to locate where to plug in the correct
activation timestamp.
In `@crates/chainspec/src/morph.rs`:
- Around line 35-43: The test test_morph_mainnet_hardforks expects all hardforks
active at timestamp 0 but the MORPH_MAINNET genesis config lacks timestamp-based
activation fields; either add the missing fields (bernoulliTime, curieTime,
morph203Time, viridianTime, emeraldTime) with value 0 to the mainnet genesis
JSON so MORPH_MAINNET.is_..._active_at_timestamp(0) returns true, or change
test_morph_mainnet_hardforks to assert the actual configured activation state
(remove or adjust the five assert! calls) to match the current genesis
configuration.
In `@crates/chainspec/src/spec.rs`:
- Around line 100-104: The doc comment above the method is_fee_vault_enabled()
is stale and describes a conversion; replace it with an accurate brief comment
describing this method's behavior (e.g., "Returns whether the fee vault is
enabled.") so readers and docs match the implementation; update the triple-slash
comment immediately above the pub fn is_fee_vault_enabled(&self) -> bool { ... }
to reflect that it simply delegates to
self.info.morph_chain_info.is_fee_vault_enabled().
In `@crates/consensus/src/validation.rs`:
- Around line 151-164: The gas-limit delta validation is being applied
unconditionally in validate_header_against_parent causing post‑Curie blocks to
be rejected; change validate_header_against_parent so it first determines
whether the block is pre‑Curie (using the header/fork metadata available on
SealedHeader<alloy_consensus::Header> — e.g., a pre‑Curie check provided by the
Header or chain/fork info) and only invoke
validate_against_parent_gas_limit(header.header(), parent.header()) when that
pre‑Curie condition is true; leave the other validations
(validate_against_parent_hash_number and validate_against_parent_timestamp)
unconditional.

Use Morph's receipt root calculation to ensure DA-compressed encoding is applied.
The code converts MorphReceipt to ReceiptWithBloom and calls alloy_consensus::proofs::calculate_receipt_root, but MorphReceipt implements a custom encode_2718 that explicitly omits bloom for DA layer compression ("it can be recalculated from logs"). Morph defines its own calculate_receipt_root function (crates/primitives/src/receipt/mod.rs:416-420) that uses ordered_trie_root_with_encoder with this no-bloom encoding. Using the standard alloy calculation instead may produce a different receipt root. Replace with the Morph-specific implementation to ensure consistency with the intended DA compression.

InMemorySize undercounts non‑L1Msg receipts.
as_receipt() drops L1/AltFee fields, so memory accounting ignores those allocations. This can skew cache sizing and metrics. Consider matching variants and delegating to the full receipt type size.

Propagate deserialization errors for hardfork configuration.
When hardfork data is provided in the genesis file but malformed, .ok() silently converts the error to None, making it indistinguishable from an omitted field. This can cause data loss and incorrect fork schedules without alerting the user. Propagate errors instead so invalid hardfork config is caught during genesis parsing.

💡 Result:
I couldn’t find any get_deserialized method in the alloy-serde 1.1.3 API. The alloy-serde crate docs (crate page and module index) do not list a get_deserialized item. See the crate docs: [1], [2].
If you meant a different crate (or a different version) please tell me which one and I’ll look it up.

Preserve deserialization errors for morph config.
When morph is present but malformed, the if let Some(Ok(...)) pattern fails to match Some(Err(...)), causing the code to fall through to the else branch and report "missing_field" instead of the actual deserialization error.
🛠️ Suggested fix
- if let Some(Ok(morph_config)) = others.get_deserialized::<Self>("morph") {
- Ok(morph_config)

Prevent CLI panic on invalid or non-Morph genesis.
User-supplied inputs can panic because MorphChainSpec::from(genesis) expects Morph-specific fields in the genesis config. When parsing custom genesis files (lines 41-46), validate with MorphGenesisInfo::try_from() to ensure the required "morph" field exists before converting to MorphChainSpec.

avoid panics by validating the parsed genesis before calling
MorphChainSpec::from: after calling reth_cli::chainspec::parse_genesis(s)
convert its result into MorphGenesisInfo via MorphGenesisInfo::try_from(...) and
return an Err if that conversion fails (indicating the required "morph" field is
missing); only on successful try_from should you call MorphChainSpec::from(...)
and wrap it in Arc::new(...). This ensures chain_value_parser returns a proper
eyre::Result rather than panicking for non-Morph genesis files.

Preserve ChainSpec fields when converting and apply Morph hardforks.
From<ChainSpec> currently discards the original ChainSpec and rebuilds from only genesis, losing preconfigured fields like bootnodes and deposit contract. Additionally, the suggested fix in the code review is incomplete—it would preserve the original ChainSpec but skip applying Morph hardforks, which the current From<Genesis> implementation adds via base_spec.hardforks.extend(). The fix must both preserve the original spec and apply the Morph hardfork logic (block-based: Bernoulli/Curie; timestamp-based: Morph203/Viridian/Emerald).
🤖 Prompt for AI Agents
In `@crates/chainspec/src/spec.rs` around lines 121 - 125, The current
From<ChainSpec> for MorphChainSpec discards ChainSpec fields by converting only
genesis; update it to start from the full ChainSpec (preserving fields like
bootnodes, deposit_contract, boot_nodes, and any other preconfigured fields) and
then apply the same Morph hardfork extension logic used in the From<Genesis>
implementation: build the base MorphChainSpec from the ChainSpec (not just
genesis), then extend base_spec.hardforks with the Morph hardfork entries
(block-based forks: Bernoulli and Curie; timestamp-based forks: Morph203,
Viridian, Emerald) using the same conditions and ordering as in the
From<Genesis> path so both original fields and Morph hardforks are preserved.
