Comment out shielded query services pending dapi-grpc protobuf types - Fix struct field mismatches in shielded tests (flags/value_balance renamed) - Fix proof verification: use correct flags and value_balance for bundle reconstruction (ShieldedTransfer was ignoring fee, Unshield/ShieldedWithdrawal used wrong flags constant) -

In `shielded_proof.rs:169`, the expression `-(v0.amount as i64)` wraps for values > `i64::MAX` due to two's-complement truncation. + +For example, if `amount = i64::MAX as u64 + 1`, then `amount as i64 = i64::MIN`, and `-(amount as i64)` wraps back to `i64::MIN` in release mode. The `value_balance` passed to `reconstruct_and_verify_bundle` would be semantically wrong. + +The Orchard `BatchValidator` binding signature check prevents exploitation (an attacker would need to construct a valid proof over the corrupted value_balance, which is cryptographically infeasible), but defense-in-depth requires catching this at structure validation time. + +Comparison with peer types: +- `UnshieldTransitionV0`: checks `unshielding_amount > i64::MAX as u64` ✓ +- `ShieldedTransferTransitionV0`: checks `value_balance > i64::MAX as u64` ✓ +- `ShieldedWithdrawalTransitionV0`: checks `unshielding_amount > i64::MAX as u64` ✓ +- `ShieldFromAssetLockTransitionV0`: checks `value_balance > i64::MAX as u64` ✓ +- `ShieldTransitionV0`: only checks `amount > 0` ✗ + +**Fix**: Add `amount > i64::MAX as u64` check to `ShieldTransitionV0::validate_structure`. + +--- + +#### H2: Unshield/ShieldedWithdrawal `fee_amount` hardcoded to 0 + +**Status**: KNOWN (TODO in code) +**Location**: +- `packages/rs-drive/src/state_transition_action/shielded/unshield/v0/transformer.rs:21` +- `packages/rs-drive/src/state_transition_action/shielded/shielded_withdrawal/v0/transformer.rs:73` + +Both transformers set `fee_amount: 0` with `// TODO` comments.

The doc comment (lines 55-56) correctly states `fee = value_balance - amount`, but the implementation passes `unshielding_amount` directly without computing the subtraction. + +This means the minimum fee check compares the total withdrawal amount against the minimum fee threshold, which trivially passes for any meaningful withdrawal. A withdrawal of 1,000,000 credits with 1 credit fee would pass a minimum fee of 111,548,800 only if `unshielding_amount >= 111,548,800`, so the check does provide a floor — but it's on the total outflow, not the fee portion. + +**Fix**: Restructure to compute `fee = unshielding_amount - recipient_amount` or separate the fields. + +--- + +#### M2: Missing minimum fee check in `check_tx` path + +**Status**: OPEN +**Location**: `packages/rs-drive-abci/src/execution/validation/state_transition/check_tx_verification/v0/mod.rs` + +The `check_tx` FirstTimeCheck path validates the ZK proof (`validate_shielded_proof` at lines 138-147) but does NOT call `validate_minimum_shielded_fee`. The import for `StateTransitionShieldedMinimumFeeValidationV0` is absent. + +In the block proposal path (`processor/v0/mod.rs`), minimum fee validation is deliberately ordered BEFORE proof verification (cheap check before expensive check). The `check_tx` path skips the cheap check and goes straight to expensive proof verification. + +An attacker could submit shielded transitions with insufficient fees that trigger expensive ZK proof verification during `check_tx`, wasting validator CPU. The transitions would only be rejected during block processing. + +**Fix**: Add `validate_minimum_shielded_fee` to check_tx before `validate_shielded_proof`, mirroring the process_proposal ordering. + +--- + +#### M3: `ShieldedTransferTransition` allows `value_balance == 0` + +**Status**: OPEN +**Location**: `packages/rs-dpp/src/state_transition/state_transitions/shielded/shielded_transfer_transition/v0/state_transition_validation.rs` + +The structure validation only checks `value_balance <= i64::MAX` but not `value_balance > 0`.

Subject: [PATCH 19/21] refactor(drive): extract shielded pool GroveDB operations into Drive methods Move raw GroveDB operations out of drive-abci into proper Drive methods, following the existing versioned method pattern. This addresses review feedback that drive-abci was directly manipulating drive internals. New Drive methods: - record_shielded_pool_anchor_if_changed: reads commitment tree anchor, writes to anchor trees if changed - prune_shielded_pool_anchors: queries and deletes old anchors below cutoff height - has_shielded_anchor: O(1) key lookup for anchor existence - has_nullifier: O(1) key lookup for nullifier existence - read_shielded_pool_total_balance: reads pool balance sum item - shielded_pool_notes_count: counts notes in commitment tree Drive-abci callers updated to use the new Drive methods instead of direct grove operations.
