Wallet Transaction Broadcast Separation Policy
Wallet transaction broadcast separation policy defines when the actor who signs a transaction should be different from the actor or system that broadcasts it, and what controls keep that split from becoming a new mutation risk.
What does this control solve?
Wallet transaction broadcast separation policy defines when the actor who signs a transaction should be different from the actor or system that broadcasts it, and what controls keep that split from becoming a new mutation risk.
Broadcast separation should connect post-sign integrity and execution window control so the release step stays bounded after signers finish their review.
Control map
What controls should teams define first?
| Control | Purpose | Failure if weak | |
|---|---|---|---|
| Role split | Separate key custody from release mechanics | One actor controls too much of the path | |
| Release authority | Define who can broadcast and when | Coordinator becomes hidden executor | |
| Execution logging | Preserve traceability after release | Investigation and control learning degrade |
How should teams operationalize it?
Broadcast separation should connect post-sign integrity and execution window control so the release step stays bounded after signers finish their review.

Frequently Asked Questions
Why separate signing from broadcasting at all?
It can reduce key concentration and improve operational safety, but only if the release step is controlled tightly enough to prevent hidden mutation or timing abuse.
What is the main failure mode?
A broadcast coordinator quietly gaining too much power over timing, routing, or payload integrity after signers believe the review is complete.
