In Bron, every outgoing transaction — whether it's a crypto withdrawal or an internal transfer — must be signed by a team member who holds both the required permissions and key shards. This ensures security, but it also introduces operational delays:
The signer must be available in person,
And manual approval takes time, especially across time zones or during off-hours.
For some businesses, this manual signing process leads to unacceptable operational overhead. Others require full automation of trusted transactions.
Hot Signer is a secure software solution provided by Bron that you install and run on your own infrastructure (e.g. cloud or private server). Once set up, it automatically signs transactions via API — no manual involvement required.
How It Works
You deploy Hot Signer inside an isolated Docker container on your infrastructure.
The signing shards are encrypted by key stored in your cloud provider’s Key Management System (KMS).
A Bron team member with "owner" permissions and access to the shards can securely share them into the Hot Signer container after deployment.
Once set up, Hot Signer can sign transactions automatically.
Note: Only users with owner rights and access to shards can provision Hot Signer.
Security Considerations
While Hot Signer is designed with strong isolation and encryption, Bron does not control how it is installed or maintained on your infrastructure. Its security ultimately depends on your deployment practices.
We strongly recommend working with your DevOps or security team, and reaching out to us for guidance if needed.
