Module maintain 

Transaction pool maintenance tasks.

Structs

PendingStalenessTracker 🔒

Tracks pending transactions across snapshots to detect stale transactions.

TempoPoolState 🔒

Tracking state for pool maintenance operations.

TempoPoolUpdates

Aggregated block-level invalidation events for the transaction pool.

Enums

AccountKeychainPoolEvent 🔒

Transaction-pool relevant subset of IAccountKeychain::IAccountKeychainEvents.

FeeManagerPoolEvent 🔒

Transaction-pool relevant subset of IFeeManager::IFeeManagerEvents.

Tip20PoolEvent 🔒

Transaction-pool relevant subset of ITIP20::ITIP20Events.

Tip403PoolEvent 🔒

Transaction-pool relevant subset of ITIP403Registry::ITIP403RegistryEvents.

Constants

DEFAULT_PENDING_STALENESS_INTERVAL 🔒

Default interval for pending transaction staleness checks (30 minutes). Transactions that remain pending across two consecutive snapshots will be evicted.

EVICTION_BUFFER_SECS 🔒

Evict transactions this many seconds before they expire to reduce propagation of near-expiry transactions that are likely to fail validation on peers.

NEW_TX_DRAIN_LIMIT 🔒

Maximum number of new-transaction events to receive in a single maintenance wakeup before yielding back to the event loop. Bounds the per-wakeup work so a sustained burst of new transactions cannot starve block-commit processing.

Functions

decode_event 🔒

Decodes after the caller has matched topic0, avoiding the allocating invalid-signature error path for unrelated events.

first_topic 🔒

maintain_tempo_pool

Unified maintenance task for the Tempo transaction pool.
