Current Limitations

This page captures what is available now vs planned.

Available now

  • Cryptographic message verification with stack-selected relayer and verifier modules.
  • Destination-side message authentication/verification in ConceroClient / ConceroClientBase.
  • Dynamic message fee based on selected modules and chain inputs.
  • Retry functions for retryable submissions.

Current shipped module defaults

  • Current Concero-run relayer and verifier modules are admin-gated via allowlists/roles.
  • Integrators can choose custom modules, including permissionless implementations, in their own message stack.

Planned (not available yet)

  • Custom RPC selection exposed directly via relayer metadata and verifier metadata.

Integration guidance

  • Build your app assuming current shipped module behavior.
  • Treat planned metadata-level RPC selection as future capability.
  • Keep module choices and app verification policy explicit in your app docs and runbooks.
