BIP 331 explored transaction package relay improvements
BIP 331 proposes package relay rules that consider a child transaction together with its unconfirmed ancestors for fee evaluation.
Package-aware relay can help fee-bumping patterns where a low-fee parent is paired with a higher-fee child.
The proposal addresses mempool policy, an operational layer that affects how transactions propagate without changing consensus validity.
Relay improvements can make fee management more predictable, but miner inclusion and network policy remain distinct from wallet estimates.
