Package Relay
The ability for nodes to relay groups of related transactions together so miners evaluate fees on the package total.
- Type
- mempoolpolicy
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
