Security

Last updated: August 26, 2026

This page summarizes security expectations for Autlantic Billing merchants and integrators. For settlement and custody positioning, see Settlement overview.

API keys and secrets

  • Store API keys and webhook secrets in environment variables, not source control.
  • Use Test keys (abk_test_…) in staging and Live keys (abk_live_…) in production. Do not mix modes.
  • Rotate keys and webhook endpoint secrets if they may have leaked.

Webhooks

Verify the x-autlantic-signature header against the raw request body and the signing secret for that endpoint before trusting an event.

Settlement

Customer USDC settles on Base to the merchant payoutAddressEvm. Autlantic does not custody customer subscription revenue.

Relayers

Autlantic may operate relayers to sponsor gas and submit billing transactions. Relayers are not used to custody customer or merchant subscription balances. See Settlement overview.

Incident reporting

Report suspected security issues privately to [email protected]. Include enough detail to reproduce the issue without sharing production secrets in public channels.
