d14n migration

D14n Migration 2026 v3 (RFC)

Overview

The Introduction of decentralization necessitates a strategy to move users from "legacy" v3 infrastructure/client to the new decentralization (d14n) infrastructure/client. We want users to experience minimal friction in this process — ideally, the migration to d14n remains completely opaque to the common user. Nevertheless, the migration poses some fundamental challenges:

  • how to migrate data from the centralized infrastructure to d14n (decentralization), without causing group corruption (client + backend; this document focuses on client).
  • how to preserve group, identity and invite state to remain consistent between client, v3 backend, and d14n backend.
  • how to test a migration locally to gain confidence in its implementation

Modular Gateway

  • Problem:
    • Need to build Resolver, Inbox and L2 Node services but provide a consistent API for libXMTP that is quickly iterable on both ends (Gateways and libxmtp)
  • Need:
    • Easy to create more than one gateway
