A server key signer uses a P-256 or native blockchain keypair injected as an environment variable (or equivalent secret) into a server-side application. Signing happens entirely in-process with no external network call, making this the lowest-latency option available. Because this key lives as a secret in your infrastructure, enforcing regular rotations is recommended — for example, quarterly — to limit exposure in the event of a compromised environment, a departed employee, or an infrastructure incident. For a conceptual overview, see Server key in the Wallet Signers guide. To learn how to register additional operational signers on an existing wallet, see Registering a signer.
