Conversation
A MorphTx (0x7F) with `fee_token_id > 0` settles its gas fee in an ERC20 token, so the sender needs no ETH beyond `value`. `MorphPooledTransaction` inherited `EthPooledTransaction`'s cost, which is `gas_limit * max_fee_per_gas + value`. The pool compares `PoolTransaction::cost()` against the sender's ETH balance to set the `ENOUGH_BALANCE` bit in `TxState`, and a transaction missing that bit lands in the queued sub-pool. `best_transactions()` only walks the pending sub-pool, so a token payer holding no ETH had their transaction admitted by the validator and then parked forever — the exact user ERC20 gas payment exists for. morph-geth packs the same transaction: `executableTxFilter` sets `txCost = nil` when `IsMorphTxWithAltFee()` and only requires `costLimit >= value` (core/tx_pool.go:1657-1698). Report the ETH-denominated cost as `value` for token-fee MorphTx and keep the inherited cost everywhere else, including the `fee_token_id == 0` ETH-fee MorphTx path. Token affordability is unchanged: `MorphTransactionValidator` validates it on admission and re-validates it every block in `maintain_morph_pool`.

…sactions The MorphTx revalidation task runs alongside reth's own pool maintenance and both subscribe to the canonical state stream independently, so this task can observe a pool snapshot that still contains transactions the new block already executed. It read the sender's account only for the balance and discarded the nonce, so those already-executed transactions were charged against the new (already reduced) post-state balance a second time, and the sender's next, genuinely affordable transaction was evicted. Read the nonce alongside the balance and skip everything below it, as upstream's `AllTransactions::update` and go-ethereum's `demoteUnexecutables` both do. Removal used `remove_transactions_and_descendants`, which deletes every higher-nonce transaction of the sender — including plain ETH-fee transactions that are affordable on their own and only depend on the removed one through the nonce sequence. `remove_transactions` parks them instead (upstream's `remove_transaction_by_hash` calls `park_descendant_transactions`), matching what go-ethereum does by re-enqueueing its `invalids`. A failed token state read was wrapped as `TokenInfoFetchFailed` and handled like any other validation failure, so a transient read error removed a perfectly valid transaction. The rest of this task already skips on a failed state provider, L1 block info fetch or ETH balance read; token reads now follow the same rule. go-ethereum drops the transaction in this case (`executableTxFilter`, core/tx_pool.go:1690) and that is deliberately not mirrored. Also skip ahead to the newest queued notification before starting a round: a round costs one state read per transaction, so the chain can advance while it runs, and the verdicts are a pure function of the latest state. The per-round decision is extracted into `collect_removable_transactions` so it can be driven directly against a hand-built state, which is what the three new regression tests do; each was confirmed to fail before this change.

…udget
The revalidation walk applied one rolling sender budget across every MorphTx in
the pool, pending and queued alike. A transaction sitting behind a nonce gap was
therefore charged against whatever the sender's executable transactions had left
over — but the transactions filling the gap are not in the pool, so how much of
the balance is actually still owed by the time the gapped one executes is
unknown. An unrelated block was enough to evict a future-nonce transaction that
had passed admission on its own.
Stop the walk at the first nonce discontinuity, which is what upstream's
`AllTransactions::update` does ("If there's a nonce gap, we can shortcircuit,
because there's nothing to update yet"). go-ethereum reaches the same place from
the other direction: `promoteExecutables` only ever applies a per-transaction
cost check to the queue and discards `FilterF`'s `invalids`.
Nothing is lost by leaving those transactions alone: without `NO_NONCE_GAPS`
they sit in the queued sub-pool, which is exactly what reth's own stale eviction
reaps.

(cherry picked from commit 65ab7ec)
`query_balance_via_system_call` mapped every error, `EVMError::Database` included, to a zero balance. A failed state read therefore came back as "this account holds no tokens" and the transaction was rejected for insufficient funds — and the `Err(EVMError::Database(e)) => Err(e)` arm in `read_token_balance_with_fallback`, which exists precisely to propagate it, was unreachable. Report the database error and leave the revert / short-return cases as a zero balance, which are genuine statements about the token. At admission a failure to even get a state provider became `TransactionValidationOutcome::Invalid`. That is a verdict on the transaction: the pool records it as known-bad and the network layer holds the sending peer responsible for something that may be perfectly valid and merely could not be checked. Route `TokenInfoFetchFailed` to `TransactionValidationOutcome::Error` instead, which discards the attempt without blaming anyone. `TokenInfoFetchFailed::token_id` becomes `Option<u16>`: the provider failure happens before any token ID is known and was reporting a hardcoded `0`, so the error read "failed to fetch token info for ID 0" for a token that had nothing to do with it. Claude-Session: https://claude.ai/code/session_01PiUjd47Da71WG2BFkDQz9q (cherry picked from commit f1b2f0b)
The token-fee handler resolved the caller's ERC20 balance by building a throwaway `MorphEvm` over the raw database. That EVM carries `BlockEnv::default()` and `CfgEnv::default()` — block 0, timestamp 1, chain id 1, zero coinbase and base fee, `u64::MAX` gas limit — and `system_call_one` issues the call from `SYSTEM_ADDRESS` with a 30M gas cap. go-ethereum reads the same balance through `st.evm` (`GetAltTokenBalanceHybrid`, core/token_gas.go:43), so the call sees the real header, the real chain config, the user as `msg.sender` and a 200k cap. For any call-mode token whose `balanceOf` reads block context or `msg.sender`, the two clients were computing different balances for the same transaction — and that balance both caps `fee_limit` and becomes the `from_balance_before` the post-transfer equality check is measured against, so it decides whether the transaction is valid at all. Resolve it against the executing EVM instead. Slot mode keeps reading storage directly: there is no environment to get wrong, and an `sload` would warm a slot the deduction below is careful to leave cold. `evm_call_balance_of` now queries as the account being asked about, matching `sender := vm.AccountRef(userAddress)`, and returns a `Result` so a failed state read propagates rather than being reported as a zero balance — an I/O failure must not decide a block's contents. A revert or unusable return value stays a zero balance, which produces the same rejection go-ethereum reaches by erroring out of `buyAltTokenGas`. The receipt-field fallback in the block executor switches to `load_storage_only`: it only reads `price_ratio` and `scale`, both plain registry storage, and was spinning up a temporary EVM to resolve a balance it discards. No currently registered fee token is affected — every call-mode token on mainnet and hoodi is a FiatTokenV2_2 or OZ ERC20 whose `balanceOf` is a plain storage read — so this closes a latent divergence rather than an active one. Claude-Session: https://claude.ai/code/session_01PiUjd47Da71WG2BFkDQz9q (cherry picked from commit 516b71e)
The pool resolved a call-mode fee token's balance through a temporary EVM built from `MorphContext::new(db, hardfork)`, which carries `BlockEnv::default()` and `CfgEnv::default()` — block 0, timestamp 1, chain id 1 — and queried it from `SYSTEM_ADDRESS` with a 30M gas cap. go-ethereum's pool builds a real `vm.BlockContext` from the head header and calls `balanceOf` as the user with a 200k cap (`pool.getBalanceFunc`, core/tx_pool.go:330). So for a token whose `balanceOf` reads block context or `msg.sender`, admission and maintenance were answering a different question than the execution layer — admitting transactions that cannot execute, or rejecting ones that would. Thread the block's `EvmEnv` through `MorphTxValidationInput` instead. The validator caches it alongside the L1 block info, built by `ConfigureEvm::evm_env` for the head, and the maintenance task builds it for each canonical tip, so both use exactly what execution would. `read_token_balance_with_fallback` now stands its EVM up in that environment and delegates to the same `evm_call_balance_of` the handler uses, leaving one implementation of the query rather than two that can drift. `evm_call` takes the context error after running the frame group. A database failure inside a frame is recorded on the context and surfaces as a halt; running the frames directly skips the step that normally converts it, so an I/O failure was indistinguishable from the token reverting — which would have silently undone the propagation this relies on. `query_erc20_balance` and `query_balance_via_system_call` are removed: they were the only remaining way to ask this question in the wrong environment.

Assert that the token-fee transaction is removed, otherwise this test can pass without exercising parking.
The test only asserts that descendant is still in the pool. Every early-continue path in maintain_morph_pool_with removes nothing: a failed evm_config.evm_env build, a failed client.state_by_block_hash, a failed L1BlockInfo::try_fetch, or an empty morph_txs filter. In each of those cases the assertion still holds, so the test would report success without ever reaching collect_removable_transactions or pool.remove_transactions. Capture the nonce-0 hash and assert its removal as well.

`evm_call` now takes the context error before running the frame group, not only after it. Post-execution still runs after the main frame halts on a failed read, and the token refund path reaches `evm_call` with that failure still recorded on the context. The previous `debug_assert!` fired on exactly that path; in release it would have re-attributed the main frame's failure to the nested balance read. A nested call must not run in a context the main frame has already poisoned, and the failure it reports must stay the main frame's. `reimburse_caller_token_fee` re-raises `EVMError::Database` instead of logging it and continuing. Once `evm_call` takes the context error, nothing downstream surfaces it: the behaviour that previously covered this case — finalization aborting on the still-recorded error — no longer applied, so a node that failed to read the token during the refund finalized the transaction as a success without refunding. That is a state divergence keyed on I/O. A contract that rejects the refund still soft-fails, matching go-ethereum's `refundGas`. `transfer_erc20_with_evm` preserves `EVMError::Database` instead of wrapping it as `TokenTransferFailed`. The refund regression was found by the second external review of #200 and its reproduction is retained as `refund_database_failure_aborts_final_execution_result`; the `evm_call` ordering came out of verifying that mechanism against revm's `run_without_catch_error`. Claude-Session: https://claude.ai/code/session_01PiUjd47Da71WG2BFkDQz9q
…idation The nonce-gap short circuit judged continuity over the MorphTx-only list the caller had already filtered, so `Legacy(0), Morph(1)` looked gapped at nonce 1 and a MorphTx behind an ordinary transaction was never revalidated. After its token balance was spent it stayed in pending, where nothing time-evicts it. Regression from 85dae28. Walk every transaction of a sender that holds at least one MorphTx. Ordinary predecessors advance the nonce and consume the ETH budget — their spend is owed before the later MorphTx executes — and an ordinary predecessor that is no longer affordable stops the walk without removing anything, since standard maintenance owns it. Found by the second external review of #200. Claude-Session: https://claude.ai/code/session_01PiUjd47Da71WG2BFkDQz9q
…tch to it Block number and timestamp, base fee, L1 fee parameters and the EVM environment were written and read as separate fields. A canonical update racing a validation batch could pair the new block's state with the previous block's environment, and the state provider was opened by block *number*, which a same-height reorg cannot disambiguate. `MorphValidationHead` bundles hash, number, timestamp, base fee, L1 info and the `EvmEnv`, published atomically behind one `RwLock<Option<Arc<_>>>`. A batch pins one head and opens its provider by hash. The inner validator's stateful checks now run against that pinned provider too, so the account read, the token read and the environment agree on a block — previously the inner validator used `latest()` while the token read used the cached head number. Until a head has been published, validation returns `Error` (retry) rather than validating against a zero head. Note for #199: its `validate_inner_with_state` covers the same stateless/stateful split; the EIP-7623 carve-out slots in at the `validate_stateless` call here when that branch is rebased. Found by the second external review of #200. Claude-Session: https://claude.ai/code/session_01PiUjd47Da71WG2BFkDQz9q
…rphTx The mixed-sequence walk charges an ordinary predecessor's `gas × max_fee + value + L1 data fee` against the sender's ETH budget and stopped at the first one that no longer fit, leaving it to reth's own maintenance. That is only right for the part of the shortfall reth can see. Its `cost()` excludes the L1 data fee, so a predecessor that became unaffordable purely because of that fee — the oracle price rose after admission, or the balance dipped into the gap — is never parked by `AllTransactions::update`, and this walk stopped in front of it on every round. The predecessor and the MorphTx behind it sat in pending, where nothing time-evicts them, and the MorphTx was never revalidated again. Track reth's cumulative `cost()` alongside the L1-inclusive budget. When the budget fails but `Σ cost()` still fits the balance, the shortfall is exactly the L1 fees reth cannot see: remove that predecessor, which parks its descendants through `remove_transactions`, matching what go-ethereum's `executableTxFilter` does with an L1-unaffordable transaction. When `Σ cost()` itself exceeds the balance, reth parks it on its own and the walk still stops without removing anything. This only covers senders that hold a MorphTx, because that is the set this task walks. A sender with only ordinary transactions in the same L1-fee gap still stays in pending — the pre-existing asymmetry with go-ethereum, which rechecks the L1 data fee for every pending transaction each block — and is left for a dedicated change. Found by the third external review of #200; its reproduction is retained as `ordinary_l1_fee_shortfall_parks_the_morph_successor`.

Remove the pool-wide and per-sender MorphTx presence filters so ordinary-only senders enter the same per-block fee-maintenance walk. Reth's cost excludes L1 data fees, so admission alone cannot keep transactions payable after oracle updates or balance changes. Reuse the cumulative fee budgets to remove the first transaction whose L1 fees make it unaffordable and park its descendants. Keep standard maintenance responsible for plain ETH shortfalls, skip executed nonces, stop at real nonce gaps, and preserve transactions when state cannot be read. Add real-pool regressions for ordinary-only and mixed-sender pools, exact budgets, single and cumulative shortfalls, parked descendants, nonce gaps, mined nonces and both maintenance-task orders. The fee-increase regression fails before removing the filters.

Token-fee MorphTx must enter
pendingwhen its sender can pay the ETH value and ERC20 fees. This PR corrects pool cost accounting, revalidates L1/token affordability as the chain changes, and aligns internal fee-token calls with Morph geth.Pool behavior
cost()includes only ETH value. The configured local transaction fee cap is still enforced usinggas_limit × max_fee_per_gas.MorphTxValidationErrorseparates transaction invalidity from database/state failures. Only the invalid arm converts to an invalid-pool verdict; unavailable state neither evicts transactions nor marks admission attempts known-bad.(sender, token ID)for one round only. A newer notification arriving during the scan supersedes the old removal verdicts.Consensus-facing token-call changes
These changes deserve execution-layer review in addition to txpool review:
