Package Relay
The ability for nodes to relay groups of related transactions together so miners evaluate fees on the package total.
Package relay lets nodes consider parent and child transactions together, enabling CPFP and better fee market behavior. Without it, some fee-bumping strategies are less effective.
- Support varies by client and version
- Wallets may adapt strategies based on detected network capabilities
