What's in the portal​

Public site (developers.chacha.charity):

• Getting started guide — local development, first API call, environments
• Platform documentation — architecture, the Invisible Blockchain principle, auth model, event-driven architecture, data model
• REST API reference — auto-generated from the FastAPI OpenAPI spec
• Architecture Decision Records (ADRs 0001–0014, including the full migrated sequence from docs/adr/ and docs/decisions/)
• Contributing guide — code style, PR workflow, release process
• SDK and plugin stubs (coming soon)

Internal site (developers.chachain.de, Keycloak-gated):

• All public content, plus:
• Runbooks: Alembic migration drift, event architecture, Solana devnet setup
• Operations, security, infrastructure, and incidents (incremental migration)

What's next​

• OpenAPI reference populated by the real FastAPI schema (backend team's openapi-export CI workflow)
• German translation (selective pages, when commercially needed)
• SDK TypeScript + Python clients (tracking against SDK roadmap)
• Phase 4 content migration sweep: remaining docs/ subfolders

Technical notes​

The portal is built with Docusaurus 3 from a single charity-chain-developers/ codebase, producing two separate builds (build/public, build/internal). It runs on the same Helm/Ansible/Traefik stack as all ChaCha services.

Web3 vocabulary (Solana, blockchain, wallet, NFT, smart contract, on-chain) is used precisely throughout developer documentation — the "Invisible Blockchain" translation table applies to donor-facing UI copy only.
